The Argentinian airline Aerolineas has suspended domestic ticket sales until Mar 25. They say multiple aircraft were recently damaged by hail in SABE/Buenos Aires during a storm on Mar 14, which means they now need to reprogram their schedule until the aircraft get fixed.

The aircraft that sustained the damage were 15 Boeing 737’s in the airline’s domestic and regional fleet. Strangely, perhaps, no other airlines have reported similar damage to their aircraft from the storm.

Aerolineas say they are now assessing the aircraft damage with help from Boeing, with the hope that they will have most of the aircraft back in operation before the Easter travel weekend.

FACT/Cape Town is facing a fuel restriction, no fuel available as of now (20 MAR 2018). The reason for the restriction is not known, but we have reached out to several suppliers who have all confirmed the same information.

We’re checking up to find the reasoning, as well as an estimated date of availability.

The Iraqi Prime Minister has lifted the government ban on international flights to the Kurdish airports ORER/Erbil and ORSU/Sulaymaniyah.

The central government will take full control of the airports, and will start allowing international flights to resume in the coming days. No international flights have operated from these airports since the end September 2017. Their closure was seen as a punitive measure taken by the Iraqi central government following the September 25th independence referendum in the Kurdistan Region.

The authorities have now withdrawn the Notams that were previously in place for both of these airports advising that they were closed to international flights. Both Iran and Turkey currently still have Notams in place prohibiting flights to these airports from using their airspace – but we expect these to be updated soon to reflect the lifting of the ban.

For the first time in over twenty years, the city’s second airport, SBSP/Congonhas, will be open to international flights, from 9-18th March 2018.

This is happening as the World Economic Forum on Latin America 2018 will be taking place in Sao Paulo from Mar 13-15, and as space is limited at the main airport, SBGR/Sao Paulo International, the authorities think they’ll need extra space for attendees’ aircraft. So at SBSP/Congonhas, only BA/GA will be accepted, and nothing larger than 737BBJ / A319ACJ.

This will also serve as a trial period to check if the airport could regain its international status on a permanent basis. Scheduled international flights stopped operating from Cogonhas back in 1985, and the airport finally lost its international status in 2008.

The airport’s runways were resurfaced last resurfaced back in 2007, but were not extended because of the rapid growth of Sao Paulo, which has now completely surrounded the airport. The longest runway is 1940 meters, and the airport is open from 07-23 local time, seven days a week.

On 1st April 2018, Fraport will be increasing the rates for landing and parking fees at the 14 international airports it manages in Greece: Aktion, Chania, Corfu, Kavala, Kefalonia, Kos, Lesbos, Mykonos, Rhodes, Samos, Santorini, Skiathos, Thessaloniki and Zakynthos.

Parking charges used to be simple here: at every airport, it was free for the first five hours, and then EUR 1.08 per ton (MTOW) for every 24 hours after that. That same price applied regardless of aircraft size.

Now things are set to become a little more complicated, but effectively, parking will now be at least twice as expensive as it used to be, with even higher costs being introduced for longer stays during the summer months:

Landing fees are going up too. Aircraft below 10 tonnes have always had to pay a flat fee, and from 1st April, these are set to double. For larger aircraft, Fraport set the rate per ton (MTOW), and with the exception of LGKV/Kevala and LGSA/Chania, these are being increased across the board:

Operating to these Greek airports has become increasingly challenging since their privatisation in April 2017. Fraport initially struggled to deal with providing parking to non-scheduled and business aviation, and new slot procedures were introduced to try to better manage the volume of requests being made.

Ryanair have already complained about the price hike, as well as a new EUR 90 fee that will be charged to send a fire engine every time a plane refuels whilst passengers are being boarded – something which they say does not happen anywhere else in the world except Greece.

With the new rates set to come into force on 1st April 2018, many operators may prefer to take their business elsewhere. As the President of Corfu CAA Association, Dimitris Roussos, says – “[the price increase] is exorbitant and almost prohibitive. A lot of people will choose other airports such as Ioannina which have lower charges and where they can refuel and spend 1-2 days instead of coming to ‘expensive’ Corfu. It is quite probable that we will see the Corfu Air Club move to Ioannina as well as a significant decrease in the number of small private aircraft visiting Corfu in the summer.”

Full details of the changes to the landing and parking fees at all 14 airports can be found on Fraport’s dedicated page.

The FAA has revised its warning for Kenyan airspace – the area to ‘exercise caution’ is now limited only to that airspace east of 40 degrees East longitude below FL260 (i.e. the border region with Somalia, and 12nm off the east coast of Kenya). Prior to this, their warning applied to all airspace in Kenya below FL260.

Published on 26 Feb 2018, the warning maintains the same wording to clarify the type of weapons and phases of flight that the FAA is concerned about, specifically:

• fire from small arms,
• indirect fire weapons (such as mortars and rockets), and
• anti-aircraft weapons such as MANPADS.

The scenarios considered highest risk include :

• landings and takeoffs,
• low altitudes, and
• aircraft on the ground.

The updated guidance is intended for US operators and FAA License holders, but in reality is used by most International Operators including EU and Asian carriers, since only four countries currently provide useful information on airspace security and conflict zones.

The Notam uses FL260 as the minimum safe level, though we would suggest, as usual, that a higher level closer to FL300 is more sensible.

You can read the NOTAM in full on our Kenya page on SafeAirspace.net, a collaborative and information sharing tool used by airlines, business jet operators, state agencies, military, and private members of OPSGROUP.

Sectors of airspace over southern Germany are ahead of schedule with plans to bring in Free Route Airspace (FRA). With effect from 1st March 2018, FRA will be implemented in the EDUU/Karlsruhe UAC, EDWW/Bremen ACC , and EDMM/Munchen ACC above FL245.

By the end of 2019, most European airspace is expected to have implemented Free Route Airspace, with all airspace having this type of operations by 2021/2022.

We like the idea of Free Route Airspace – direct routing is the way of the future. We also like cool maps. Thankfully, good old Eurocontrol have provided us with some great ones, showing where Free Route Airspace currently exists, and where it will be implemented in the future:

For everything you could possibly want to know about FRA in Europe, check out Eurocontrol’s page on it here: http://www.eurocontrol.int/articles/free-route-airspace

Update: November 1st, 2019: The Notam Team is up and running – we’re fixing Notams. Follow our progress at fixingnotams.org.

We think Notams suck. No other way to say it. After a few articles we wrote (BS Notams, The Notam Goat Show, and more worryingly, the MH17 Notam problem), we got some feedback in the comments section. And thought we should share, because they really show the problem. So, here they are.

Caution, some strong language!

We’re working on a solution, so you can help and add your thoughts as a comment below. Also, send us the really bad ones and enter the 2018 Notam Goat Show contest.

Personally I think taxiway and apron closure NOTAMs are too readable, I think they should be distributed in RADIAL/DME format, or perhaps raw Lat-Lon. Additionally, time should be specified in seconds since the founding of the FAA.

Post your thoughts below!

It’s not only the North Atlantic that will be seeing PBCS being implemented on March 29th – on that same date, the weird acronym is coming to Singapore too!

However, the requirements for Singapore airspace are slightly different to that for crossing the NAT.

The short of it – compliant aircraft will be allowed a reduced separation of 50NM (or 10 minutes in trail) on certain airways: L642, M635, M767, M771, M774 and N884. For everyone else, it’ll be 80NM (or 20 minutes in trail). For Singapore, ‘compliant aircraft’ basically means anything with RNP10, CPDLC and ADS-C capable of the RCP240 / RSP180 performance requirement.

You’ll still need to obtain some kind of operator approval from your State of Registry. As we mentioned in our article on PBCS on the NAT – the best way to do that will probably be to submit an AFM Statement of Compliance for PBCS, showing exactly what data link communication systems you aircraft has, along with the selected performance.

For Singapore, if you want to operate on those airways at the reduced separation, here’s what you’ll need to remember to include in your ATC FPL:

In 10a:

In 10b:

In Item 18:
Make sure you include SUR/RSP180 to show you’re capable of the RSP180 performance requirement.

For more info, check out the full AIC published by Singapore here.

2018 version – NAT Doc 007

The 2018 version of NAT Doc 007, North Atlantic Airspace and Operations Manual, was published in January 2018 by ICAO/NAT SPG.

Download the original document here (PDF, 5mB), and see also:

• The North Atlantic page with a summary of the changes so far in 2018
• The FSB/OPSGROUP NAT Ops Guide – “My First North Atlantic Flight is tomorrow“

2018 is off to a flying start again with NAT changes – these are the latest important changes. These are also published in the latest edition of NAT Doc 007, January 2018.

• PBCS From March 29th 2018, PBCS is a requirement for the NAT Tracks between FL350-390 – RCP240 and RSP180. Read more about PBCS in our article.
• RLAT  From January 4th 2018, Shanwick and Gander increase the number of RLAT tracks – most tracks between FL350-390 will now be RLAT – 25nm separation between them.

And there will be more! Keep an eye on the FSB NAT Changes page, we’ll keep it updated.

Feb 2nd, 2018: FSB updated the full NAT Crossing Guide “My first North Atlantic Flight is tomorrow“.

– What’s different about the NAT, changes in 2018, 2017, 2016, 2015, NAT Quick Map
– Routine Flight Example #1 – Brussels to JFK (up at 5.45am)
– Non Routine-Flights: No RVSM, No RNP4, No HF, 1 LRNS, No HLA, No ETOPS, No TCAS, No Datalink – what you can do and where you can go
Take a look.

ICAO is introducing another acronym in the North Atlantic Region. This time, it’s PBCS (Performance Based Communication and Surveillance), and from March 29th 2018 you will need to be compliant if you want to fly on the half-tracks between FL350-390.

Initially, there will only be a maximum of three daily tracks where you will need to be PBCS-compliant between FL350-390. These will likely be the same tracks as we currently see being assigned as ‘half-tracks’ each day.

This requirement will eventually be extended to all the NAT tracks between FL350-390, but we understand that will only happen when the filing of PBCS designators on flight plans reaches the 90% mark, or 28^th March 2019 – whichever comes first. Either way, the ‘transition period’ for this PBCS implementation is set to last six months, so the roll-out of the requirement to all the tracks won’t happen until Oct 2018 at the earliest!

But from March 29th 2018, Shanwick and Gander will basically just continue the concept used in the RLatSM trial – whereby daily tracks spaced at less than 60nm from an adjacent track will be specified as a ‘PBCS Track’ and will be notified in the Track Message Remark-3.

So what is PBCS?

PBCS is the thing that will replace two trials in the NAT which are both coming to an end on March 29th:

• RLAT – Reduced Lateral Separation Minimum: where a reduced lateral separation of 25 nm has been implemented on the tracks between FL350-390 (so now there are extra “half tracks” each day, spaced by one-half degree of latitude)
• RLong – Reduced Longitudinal Separation Minimum: in the Shanwick Oceanic Control Area (OCA), longitudinal separation has been reduced to 5 minutes between aircraft following the same track.

When these trials end, PBCS standards will be introduced to continue to allow the application of both reduced lateral and longitudinal separation for aircraft that meet the Required Communication Performance (RCP) and Required Surveillance Performance (RSP) specifications.

How do I comply with PBCS standards?

To operate on the PBCS tracks between FL350-390, you will need to be RNP4 compliant, with CPDLC capable of RCP240, and ADS-C capable of RSP180.

But watch out! Some aircraft do have ADS-C and CPDLC but have never demonstrated RCP or RSP, and have no statement of compliance (e.g. most Honeywell Primus aircraft and several early Boeing aircraft). These aircraft may struggle to get approval to operate in PBCS airspace. Which brings us neatly on to…

Do I need PBCS approval from my state of registry?

PBCS approval will differ depending on which country operators are from.

For UK operators, check the requirements here.

US operators will need to update their LOA for Data Link Communications (A056). The FAA have published a new guide, which tells operators exactly what they need to do to get this authorisation, namely:

1. Submit an AFM Statement of Compliance for PBCS, showing exactly what data link communication systems you aircraft has, along with the selected performance
2. Since July 2016, various oceanic FIRs have been collecting data on whether certain aircraft meet RSP and RCP criteria. You need to make sure your aircraft isn’t already listed as having failed to meet these criteria, by checking here: https://www.faa.gov/air_traffic/separation_standards/pbcs_monitoring/

What new codes do I need to put down on my flight plan?

• FANS 1/A CPDLC equipped aircraft planning to operate in the NAT HLA shall insert the appropriate designator (J2, J3, J4, J5 and/or J7) in Item 10a of the flight plan.
• FANS 1/A CPDLC RCP 240 compliant aircraft intending to operate in the NAT HLA shall insert the designator P2 in Item 10a of the flight plan.
• FANS 1/A ADS-C compliant aircraft planning to operate in the NAT HLA shall insert the designator D1 in Item 10b of the flight plan.
• FANS 1/A ADS-C RSP 180 compliant aircraft planning to operate in the NAT HLA shall insert SUR/RSP180 in Item 18 of the flight plan.
• RNP 4 compliant aircraft planning to operate in the NAT HLA shall insert PBN/L1 in Item 18 of the flight plan.

If I’m not eligible for PBCS, where can I go? 

ATC may allow you to do either of the following, depending on how stressed/busy they are (i.e. decided on a ‘tactical basis’):

• You can infringe on the daily PBCS tracks between FL350 – FL390 at only one point (including Oceanic Entry/Exit Point) i.e. cross but not join an NAT PBCS track
• You can climb or descend through levels FL350 – FL390 on a PBCS track provided the climb or descent is continuous.

In their NAT OPS Bulletin 2018_001, ICAO have published a handy little picture to demonstrate this:

Heavy clashes broke out in the Libyan capital Tripoli on Jan 15, leaving at least twenty people dead and forcing HLLM/Mitiga airport to close for five days, re-opening again on Jan 20.

Gunfire at the airport damaged multiple aircraft, including a few A319s and at least one A330.

Here are some photos of some of the damage:

Both airports in Tripoli are focal points for fighting. Given their strategic value, they periodically serve as headquarters for various local militias.

HLLT/Tripoli has been more or less completely closed since mid-2014, when at least 90% of the airport’s facilities were destroyed in fighting between local militias. Since then, international flights to and from Tripoli have been using HLLM/Mitiga instead. Technically, HLLT/Tripoli is now only available for VIP, emergency and ambulance flights; but in reality, it should be avoided at all costs.

HLLM/Mitiga is the old military airfield, which is now being used for civilian traffic, since the closure of HLLT/Tripoli. However, the airport has been plagued by violence over the past few years, and has been forced to close a number of times.

Back in July 2017, we reported on the intense fighting that took place at Mitiga airport where 5 people were killed and 32 injured, and then on 19 Oct 2017, a Libyan Airlines A330 at the airport was hit by gunfire during an exchange of fire between local militia in the district directly south of the airport.

A number of countries already have blanket warnings in place against operating to Libya, and they all say pretty much the same thing: avoid the entire country – don’t land at any airport, don’t even overfly.

So we suggest you ignore whatever gets pumped out on the HLLL FIR Notams about airports being “AVAILABLE H24 FOR INTERNATIONAL FLIGHTS AND EN-ROUTE DIVERSIONS”. (You can read that nonsense in full by clicking here.)

Libya remains categorised as a Level One country (Do Not Fly) at safeairspace.net

Back in December 2017, the U.S. FAA issued KICZ A0025/17 which lifted the full ban on the Baghdad FIR, and allowed U.S. operators to overfly the country above FL260.

Now the three other big countries that regularly publish airspace safety information—France, Germany and the UK—have followed suit with new advice of their own.

France recommends that overflights should only be on airways UM860 and UM688, and should be at or above FL320.

The UK says that overflights should only be on airways UL602 to ALPET, UM860 and UM688, and should be above FL250.

Germany just say that overflights should be at FL260 or above.

Back in November 2017, several international airlines (Emirates, Turkish) resumed Iraq overflights after their national authorities removed restrictions. With the announcement that Iraqi forces had defeated ISIS and that the country had been fully returned to government control, the airspace risk in Iraq has reduced.

Iraq has published a few of its own Notams with various different areas of closed airspace at lower levels due to ongoing military operations. The only one that affects the higher flight levels is in the north-west, along the border with Syria, where a no-fly area has been introduced from SFC-FL460.

However, airways UM860 and UM688 (the two main routes through the Baghdad FIR) to the east of this zone are unaffected, and now effectively open above FL260.

This means that operators will have shorter routes through the Middle East available once again. Emirates is already reported to be routing around 150 flights a day via Iraq, rather than having to take longer routes via Saudi Arabia or Iran – so expect this bit of airspace to start to get busy again soon.

Effective January 1st, 2018, the official line is that you need an 8.33 VHF Radio to operate anywhere in Europe. If you’re heading to Europe without one, expect problems.

Until now, it’s really only been a requirement above FL195 – 8.33 has been around at the higher levels since 2007. However, Europe is keen to get everyone on the same page and make sure new frequencies can be used by all aircraft at the lower levels also.

However, not everywhere is actually requiring 8.33 just yet.  Eurocontrol have built a handy tool that shows each the requirements for each airspace sector. Click on the image below to check it out.

Can I get an exemption? If you’re operating a ferry, delivery, or some other flight where you don’t have 8.33, then you should be able to get an exemption to operate without 8.33 – but it will vary state to state. Write to the Ministry of Transport for the particular state.

Eurocontrol have published all the details on this as follows:

Above FL195, in the IFPZ, not equipped aircraft may be exempted from the carriage of the 8.33 kHz radios (refer to the national AIP of the state concerned to see if the flight is eligible) in which case the letter Y shall not be inserted in Item 10a (Equipment), but the letter Z shall be inserted in Item 10a as well as COM/EXM833 in the Item 18 (Other Information) of the filed flight plan.

Below FL195, in the airspace of the EU member states (plus Switzerland and Norway) some airspaces may be exempted from the carriage of the 8.33 kHz radios (refer to the national AIP of the state concerned) in which case the airspace is not inserted in the area where the mandatory carriage check takes place. Such exemption will permit a non-equipped aircraft to fly but only if the flight trajectory remains exclusively in airspaces where 8.33 kHz is not mandatory.

Below FL195, in the airspaces of the EU member states (plus Switzerland and Norway), state aircraft non-UHF and non-833 are exempted. The letters Y and U shall not be inserted in Item 10 (Equipment), but STS/STATE shall be inserted in the Item 18 (Other Information) of the filed flight plan.

In the IFPZ, State aircraft that are not equipped with 8.33 kHz capable radios but are equipped with UHF shall be permitted to fly in 8.33 kHz airspace where UHF coverage is provided or special procedures are implemented (see the national AIP of the State concerned). To indicate such, the letters U and Z shall be inserted in Item 10a (Equipment) and ‘COM/EXM833’ shall be inserted in Item 18 (Other Information) of the filed flight plan.

Confused? Here’s a quick crib-sheet of what to do:

When you file a flight plan in Europe, it goes through the automated IFPS system, which is now quite clever at checking for 8.33 kHz radio compliance.

The IFPS system will crosscheck between the concerned airspaces crossed by the flight plan and the radio communication equipment indicated in Item 10: (Equipment) and Item 18 (Other information) provided in the submitted message.

Here’s what will happen, depending on what you put in your flight plan:

• If Item 10 (Equipment) of the submitted message contains Y, then that flight is considered to be compliant.
• If Item 10 (Equipment), of the submitted message does not contain Y, but contains Z and U and the exemption indicator COM/EXM833 is present in Item 18 (Other Information), and the flight is a STATE flight, then that flight shall be considered compliant.
• If Item 10 (Equipment) of the submitted message does not contain Y but contains the exemption indicator COM/EXM833 and the flight is not penetrating the 833_UHF_VHF region and is entirely within the 833_EUR_IFPS, then that flight shall be considered compliant.
• If Item 10 (Equipment) of the submitted message does not contain Y, neither U and Item 18 (Other Information) contains STS/STATE and the flight is exclusively in the airspace of the EU member states (plus Switzerland and Norway) below FL195 then that flight shall be considered compliant.

In all the other cases, the flight shall be considered not compliant and shall fail automatic processing!

Update Jan 23: The current phase of the trial for RLatSM Tracks will come to an end on March 29, when PBCS standards will be introduced for the NAT tracks. More info on that here.

Since Dec 2015, there have been three daily NAT tracks spaced by one-half degree between FL350-390. These are officially called ‘RLatSM Tracks’ (Reduced lateral separation minima), but we all just prefer to call them ‘Half-Tracks’.

Separating flights by one-half degree of latitude rather than the standard one degree means that aircraft can be separated laterally by 25nm, which helps improve the efficiency of North Atlantic operations.

In Jan 2018 the Half-Tracks will be expanded from the three that now run each day, first by one additional track and then (maybe) to all NAT Tracks between FL350-390 inclusive. Jan 4 is the earliest day that this might happen, but because they will be decided tactically, it will most likely be the first busy day after Jan 4.

If you want to operate on the RLatSM tracks, you’re going to need CPDLC, ADS-C, and RNP4; along with the other standard pre-requisites for operating in the NAT HLA between FL350-390: an HLA approval, TCAS 7.1, RVSM approval, two LRNS, and a working HF radio. To figure out where you are welcome on the NAT, depending on what equipment and training you have, check out our quick and dirty guide here.

One thing to be cautious of when using the half-degree tracks – most aircraft FMC’s truncate lat/long waypoints to a maximum of 7 characters, so it will often show up as the same waypoint whether you’re operating along whole or half degree waypoints. So when operating on the half-tracks, just remember to double-check the full 13-character representations of the lat/long waypoints when you enter them into the FMC.

For more details about the new RLatSM procedures, have a read of the UK AIC 087/2017 here.

Update: Yemen-based Houthi forces fired another missile into Saudi Arabia on Dec 19. Saudi Arabia claim they intercepted it south of the capital Riyadh, with no damage or casualties reported, though a loud explosion was heard throughout the capital. The Houthi forces claim they were targeting a palace in southern Riyadh. This follows the previous Houthi missile attack on OERK/Riyadh Airport on Nov 4th, when they said: “the missile that targeted King Khalid airport was a warning shot and we warn all companies to prevent landing of their planes in the UAE and Saudi Arabia airports”. A Yemeni Army spokesman has said that the November 4 missile attack on OERK was a “warning shot”.

That missile was launched from rebel territory in Yemen, specifically targeting OERK/Riyadh King Khalid airport. Although most mainstream media carried the “missile was intercepted” story, we’re not sure that this is the case – even if it was, parts of it did fall on airport property and there was a visible explosion.

The spokesman said “the missile that targeted King Khalid airport was a warning shot and we warn all companies to prevent landing of their planes in the UAE and Saudi Arabia airports”.

Given that the Yemeni rebels have demonstrated their capability of reaching their target, there is some credibility to the threat.

Operators should consider this in operations to OE** and OM** airports.

At present, there is no indication of increased threat to overflight of Saudi or UAE airspace.

On Monday, the Saudi Arabia coalition closed all air, sea and land borders with Yemen after the missile strike on Riyadh on Nov 4, effectively closing all airports in Yemen. Yemenia airlines said that the coalition, which controls Yemen’s airspace, had declined it permission to fly out of Aden and Seiyun, the only two remaining functioning airports. OYSN/Sanaa has been closed since August 2016.

Also, all UN humanitarian flights to Yemen, one of the few international operators, have been cancelled after flights were no longer given clearance from the Saudi-led coalition to land in the country.

SCATANA remains active in the southwestern portion of the Jeddah FIR, no new Notams have been issued in relation to the last few days.

Afghanistan has changed a bunch of waypoint names on its border with Pakistan today. If you’re flying that way, you’ll need to know these for when you submit your Pakistan permit – they only approve permits for specific entry/exit points.

For more details, check out the full AIP AIRAC AMDT here.

Overflight advice for Afghanistan averages out at a minimum FL250, though as with other mountainous countries we think FL320 is a better starting point. For Pakistan, the consensus among foreign authorities is to cross the OPLR/Lahore and OPKR/Karachi FIR’s at higher flight levels. For full details check out safeairspace.net

Crew onboard a Cathay Pacific flight witnessed the re-entry of North Korea’s latest missile near their position late last week. The CX893 service from San Francisco to Hong Kong on Nov 29 was over Japan at the time when North Korea launched its missile.

The crew reported: “Be advised, we witnessed the DPRK missile blow up and fall apart near our current location.”

Here’s Cathay Pacific’s full statement:

“On 29 November, the flight crew of CX893 reported a sighting of what is suspected to be the re-entry of the recent DPRK test missile. Though the flight was far from the event location, the crew advised Japan ATC according to procedures. Operation remained normal and was not affected. We have been in contact with relevant authorities and industry bodies as well as with other carriers. At the moment, no one is changing any routes or operating parameters. We remain alert and review the situation as it evolves."

North Korea’s missiles are larger, and can fly further, than the other missiles we’ve previously seen. Over the past year, most of these missiles land in the Sea of Japan, well inside the Fukuoka Flight Information Region (Japanese airspace). But as we see with this latest test, there is clearly a danger of some of these missiles not re-entering the atmosphere intact – meaning that a debris field of missile fragments passes through the airspace, not just one complete missile. If you haven’t done so already, make sure you read this: our article on why North Korean missiles are now a real threat to Civil Aviation.

This latest test is also significant because of its unprecedented altitude – 4500km (2800 miles). Experts seem to agree that if it had been fired on a standard trajectory, the missile would have been capable of traveling around 13000km (8100 miles), meaning it could have struck anywhere in the mainland US.

If you’re operating in the region, we recommend avoiding the ZKKP/Pyongyang FIR entirely and avoiding the affected areas over the Sea of Japan. For more info, check out Safeairspace.

Volcanic eruptions from Bali’s Mount Agung earlier last week forced the closure of WADD/Denpasar and WADL/Lombok airports, as volcanic ash spread across both islands.

Here’s the current situation at the airports on Dec 4:

• WADD/Bali: Re-opened on Nov 29. (Although the airport will be closed for runway repair from 18-23z daily [except Saturdays] until Dec 31).
• WADL/Lombok: Re-opened on Nov 30. 
• WARR/Juanda: Open and operating. So far has not been affected at all by the volcanic ash. (Although the airport will be closed for runway repair from 16-22z daily until Jan 06).

Although Mount Agung has now stopped emitting ash, another large eruption is still likely. The local monitoring agency are registering powerful and continuous tremors, and authorities have ordered locals and journalists within 10km of the volcano to evacuate. Further intermittent airport closures are possible, depending on wind direction.

Update 1800z Nov 30: A strike by airport workers at LLBG/Tel Aviv which was originally planned for this weekend has now been cancelled.

The Airports Authority says the strike was canceled after the government intervened and were able to reach a deal with the workers’ union to delay any strike action this weekend.

The FAA Safety Team have issued a mysterious new Notam today, about a possible fuel contamination problem at airports in the central U.S.

Update: The FAA has sent a follow up, seems things weren’t as widespread as they made it sound:

SPECIAL..NOTICE..

THE FAA CONTINUES TO INVESTIGATE A FUEL CONTAMINATION PROBLEM. SUBSTANTIAL EVIDENCE INDICATES THE CONTAMINATION HAS BEEN ISOLATED TO GENERAL AVIATION AND MILITARY AIRCRAFT AT EPPLEY AIRFIELD, OMAHA, NE (KOMA) DURING THE TIME PERIOD NOVEMBER 18-20, 2017. FAA RECOMMENDS THAT ALL AIRCRAFT OPERATORS CHECK NOTAMS FREQUENTLY FOR POSSIBLE CHANGES TO THIS ONGOING SITUATION.

FOR FURTHER INFORMATION CONTACT FLIGHT STANDARDS AIR TRANSPORTATION DIVISION AT 202-267-8166.

Here’s what they have to say:

FDC 7/4900 (A1362/17) - FL..SPECIAL NOTICE..THE FAA IS CURRENTLY INVESTIGATING 
A FUEL CONTAMINATION PROBLEM THAT HAS RECENTLY APPEARED IN JET FUEL WI THE CENTRAL U.S. THE EXACT SOURCE AND THE GEOGRAPHICAL SCOPE OF THE CONTAMINATION IS UNKNOWN. THERE HAVE BEEN REPORTS OF BLOCKAGES IN FUEL FILTERS, FUEL NOZZLES, AND FUEL TANKS. THIS HAS RESULTED IN SEVERAL ENGINE FLAMEOUTS AND OTHER ERRATIC ENGINE OPS. ALL OPERATORS ARE ADZ TO CLOSELY FOLLOW FUEL SAMPLING PROC AND REPORT ANY DISCOVERY OF CONTAMINATION OR ERRATIC ENGINE OPS TO THEIR FLIGHT STANDARDS DISTRICT OFFICE OR NEAREST FAA FACILITY. 30 NOV 00:20 2017 UNTIL 30 DEC 00:20 2017. CREATED: 30 NOV 00:48 2017

We haven’t seen or heard any reports about this issue recently. The FAA Safety Team say that this is currently still under investigation, and can’t provide any additional information just yet. We’ve also reached out to a few of the major suppliers, who are saying pretty much the same thing – no more info yet, beyond the Notam.

Several sources are telling us the NOTAM is related to a fuel issue at KOMA, limited to a single truck at a single FBO:

There seems to be no end in sight for the French Guiana ATC strikes. Here’s the current situation:

SOOO FIR: the entire airspace will be uncontrolled from 00-11z until further notice (extended beyond 01Dec).
That means there will be no ATC staff on duty during these times. Basically, during the closure, there’s a contingency plan in place: so if you want to cross this bit of airspace, there are now very specific routes and levels you have to fly at. Check these carefully prior to ops, and make sure you’re at the right flight level before crossing the FIR boundary. Once you’re inside the FIR, don’t change your speed or level.

To read the contingency plan in full, with all the published routes and what to do, click here.

TTZP/Piarco ATC (who control the FIR to the north) have said that everything has been running smoothly so far with this contingency plan, and they haven’t had any problems with directing overflying traffic from TTZP to SOOO.

SOCA/Cayenne Airport: the airport will be limited between 0100-1100Z until further notice.  This means you can’t file as an alternate, and if you’re arriving or departing during these times, you’ll need to call ATC for PPR at +594 35 92 72, or +594 39 93 02.

Emirates will be the first international airline to resume overflights of Iraq, with the first flights through the Baghdad FIR expected today, Monday Nov 27. According to FSB sources, effective 0001Z this morning the GCAA will authorize UAE based airlines to use this airspace, after several years of restrictions. Emirates anticipates that about 150 flights a day will now route via Iraq, rather than having to take longer routes via Saudi Arabia or Iran.

This is the first in several steps we expect will lead to almost full resumption of overflights over Iraq, meaning operators will have shorter routes through the Middle East available once again.

The next step will be for the FAA to authorise US carriers to overfly Iraq – most likely at FL260 or above. That approval was initially slated for the end of October, but was held back after events on the ground posed a security concern for UM860 and UM688 – the two main routes through the Baghdad FIR to Europe and vv.

The FAA were about to hit ‘publish’ on a Notam  which would have enabled US airlines to start overflying Iraq again. The text of this Notam included:

• An amendment to the existing Iraq restriction
• An authorisation for US airlines and operators to overfly Iraq at or above FL260

But then, a military operation by Iraqi forces to take control of Kirkuk from the Kurds the same day, created concern as to overflight safety. Kirkuk sits pretty much underneath the UM860 airway on the map above.

For now, only UAE carriers have been given the green light for Iraq. Other operators and authorities are likely to follow suit soon.
