Key Points

• Renewed conflict between Armenia and Azerbaijan on Sep 19, with military operations and exchange of fire in the Nagorno-Karabakh border region. Ceasefire agreed on Sep 20, coordinated by Russia.
• Azerbaijan published new Notams saying that cross-border waypoints were closed. These Notams were cancelled on Sep 20, but most operators are still actively avoiding the region, and routing north via Georgian airspace (UGGG/Tbilisi FIR) instead.
• There have been no changes to state-issued warnings. 

Update: 20 Sep 2023

Azerbaijan has cancelled its Notams which closed its airspace on the border with Armenia. But most operators are still actively avoiding the border region, and routing north via Georgian airspace (UGGG/Tbilisi FIR) instead.

A ceasefire has been agreed on Sep 20, coordinated by Russia, with further talks set for Sep 21.

Several sources report that on Sep 19 Azerbaijan targeted Armenian forces using drones, artillery, and surface-to-air-missiles. This followed a statement from the Ministry of Defense of Azerbaijan accusing Armenia of shelling the positions of the Azerbaijani Army in the Nagorno-Karabakh region.

There has been no update yet to EASA’s Conflict Zone Information Bulletin. 

No new foreign airspace warnings for Armenia or Azerbaijan have been issued yet either. Several of these were withdrawn at the end of the war in 2020. Following brief clashes in Sep 2022, only Canada issued a new airspace warning (for both countries) advising caution due to potential risk from anti-aviation weaponry and military ops.

But with the latest escalation in hostilities, we currently assess both Armenia and Azerbaijan on SafeAirspace.net as Risk Level 2: Danger Exists – any further large-scale ceasefire violations involving missiles or anti-aircraft weaponry present a risk to overflights in the border region.

Update: Sep 2022

• In September 2022 there were renewed border clashes between Azerbaijan and Armenia – the worst flare-up in hostilities since the war ended in 2020.
• The waypoints along the border between the two countries (VETEN, PEMAN, ELSIV, MATAL) were temporarily closed on Sep 13, but reopened the next day, after Russia brokered a ceasefire to end the fighting.

Update: Oct 2020

At the peak of the conflict in late October 2020, the airspace picture looked like this:

Here’s what happened at that time:

Azerbaijan

• Azerbaijan established a Temporary Restricted Area along the border with Armenia, which meant that all East-West airways between the two countries were effectively closed. 
• They also issued a Notam advising caution across the UBBA/Baku FIR due to the spillover of the conflict, with the specific warning of the threat posed by long-range missiles which they claimed Armenia had been using to target locations throughout Azerbaijan. 

Armenia

• Armenia never closed any parts of its airspace. Instead, they issued a Notam advising operators to expect tactical rerouting and short notice closures in the airspace along the border, and recommended they carry additional fuel. 

Germany

• Germany issued airspace warnings for both Armenia and Azerbaijan. It did not advise that overflights be restricted to a certain altitude, but instead warned of a “potential risk to aviation… from military operation including anti aviation weaponry.” 

France

• The airspace warnings issued by France were a bit different. Essentially, they said that operators should not overfly the border region except on certain airways in the far north of the UBBA/Baku FIR at FL340 or above.

2020 was a heck of a ride. But therein lies the risk – what else might you have missed amongst all the Covid-related noise? Sadly, conflicts and their risks to civil aviation have not taken a break during the pandemic.

As it’s a new year, we thought a summary of Airspace Risk was called for. Here’s what’s making headlines at the moment:

Saudi Arabia & Yemen

Houthi rebels in Yemen are regularly firing explosive drones and rockets across the border into Saudi Arabia, and these usually target airports in the south such as OEAH/Abha and OEGN/Jizan. Their latest attack was on OYAA/Aden airport in late December which resulted in mass casualties.

Saudi Arabia continues to retaliate with airstrikes. The latest was in the capital Sanaa just weeks ago, where multiple munitions landed near the airport.

The risk to aviation is that overflying aircraft may get caught in the crossfire or might be misidentified by Saudi air defences. Active terrorist groups in Yemen may also use anti-aircraft weaponry to target foreign interests.

The FAA prohibit all US operators from entering most of the OYSC/Sanaa FIR at any level. Only two airways are allowed, and they are well off the coast – UT702 and M999.

There are no restrictions on Saudi Arabia but use caution in the southern regions. France and Germany have issued their own warnings.

Iraq

Rocket attacks on military interests at airports have become a common occurrence. They are generally fired by local militia without warning. ORBI/Baghdad is frequently targeted, along with other airports including ORER/Erbil. There is a clear risk to aircraft at low levels.

US relations were further strained through 2020 with multiple attacks on the US embassy in Baghdad. The tensions escalated to a point where the US considering closing it.

Foreign aircraft continue to be at risk from armed militia who have access to portable anti-aircraft weaponry, while misidentification by the air defence systems of multiple foreign forces in the country is also possible.

The FAA has extended its ban on US operators entering the Baghdad FIR at any level. Even though the SFAR says you can enter above FL320, the long-running Notam KICZ A0036/30 says otherwise.

Syria

There have been several recent Israeli airstrikes on targets throughout Syria. In late December there are reports that Israeli fighters transited Lebanese airspace at low level causing alarm in Beirut before attacking targets in Western Syria. Just weeks ago, several sites around Damascus were targeted by Israeli missiles.

The primary risk is that aircraft may be misidentified by Syrian air defence systems which are regularly activated. Civil operators may get caught in the crossfire as missiles may erroneously lock on to the wrong aircraft.

The FAA are taking no chances – the ban on US operators entering the OSTT/Damascus FIR at any level has been extended a full three years to 2023.

South Sudan

Just this week ICAO issued a concerning warning about the risk to aircraft operating below FL245 in the HSSX/Khartoum FIR over South Sudan, or flying in and out of HSSJ/Juba. They are ‘gravely’ concerned about ATC disruptions, a lack of contingencies, inadequate training of controllers, limited info about equipment outages and a lack of co-ordination with other ATS units.

Emerging Conflict Zones

2020 saw three new conflict zones emerge, here is what is happening with them now.

Ethiopia

A civil conflict erupted in October last year in the Tigray region of Northern Ethiopia. The government went to war with the TPLF – a regional force seeking independence.

The region’s airports were closed and TPLF showed an intent to internationalise the conflict by attacking aviation interests. They fired rockets into Eritrea targeting HHAS/Asmara, and also attacked multiple airports to the South of the Tigray region.

Two airways were closed (T124, and M308) with no explanation of the risk.  Other airways remained open but uncomfortably close to the fight – especially UG300, UN321 and UL432. No airspace warnings were issued despite the dangers.

What’s the latest?

In late November Ethiopian forces captured the region’s capital Mekelle and regained control. Remaining TPLF forces have retreated leaving behind a humanitarian disaster and a vow to continue the fight. Since then, the airway closures have been removed and things have gone quiet, but an airspace risk remains – armed militia continue to be active in Northern regions and may be looking to make a statement. Be wary of operating in the area.

Western Sahara

Late last year the region’s independence movement (the Polisario) declared war on Morocco for breaching a ceasefire agreement. The FAA published a warning that the Polisario might have access to anti-aircraft weaponry left over from previous conflicts.

What’s the latest?

It is still an active conflict zone.  The fight has reached the international stage after the US declared their support for Morocco. The Polisario have indicated they are willing to at least talk, but so far have not put down their weapons. So, it is a wait-and-see type deal.

The risk to overflying aircraft remains. The GCCC/Canarias FIR keep extending a Notam advising operators to not fly below FL200 on the following airways: UY601, UN728 and UT975.  However, the reason is still missing: because of the risk of anti-aircraft fire. The GOOO/Dakar FIR haven’t issued any warnings despite the threat. Take care if operating in the area.

Armenia-Azerbaijan

In September last year, an ethnic conflict erupted over a disputed territory in Western Azerbaijan – Nagorno-Karabakh. The fight was between Azerbaijan and Armenia.

As a major air corridor for en-route traffic, there were significant flight disruptions. Azerbaijan swiftly closed all but one west/eastbound airway and routed traffic via Georgia. Armenia asked aircraft to take extra fuel and expect re-routes. The conflict was short but intense, with heavy artillery fire from both sides. The conflict eventually spread beyond the contested regions with longer range weapons. The entire border region posed a risk for civil aircraft.

What’s the latest?

For once the news is good. In November a ceasefire agreement was signed with the help of Russia. Armenia effectively lost and withdrew from the region and the conflict was officially over. Armenia removed its airspace warning, while Azerbaijan re-opened the affected airways and a large section of airspace near the border.

With the conflict now over, and no new reports of significant fighting since the peace agreement in November, direct crossing traffic between the two countries is now technically possible again.  However, most East-West flights are currently still electing to go further north instead, connecting between Azerbaijan and Georgia’s airspace, avoiding Armenia.
