ADIZ – International Ops 2018

Tag: ADIZ

Expanded Canadian ADIZ

As of May 24, Canada has expanded its ADIZ to include all its national territory in the Arctic Archipelago.

Requirements for operations in the ADIZ remain the same. You’ll need a transponder with altitude reporting and a working two-way radio. Remember, you’ll need to include the time and location of ADIZ border crossing in your flight plans RMK section.

Bangladesh is now one big ADIZ

6 February, 2018 / David Mumford / 0 Comments

Bangladesh has decided to establish an ADIZ over the entire country, including a massive chunk of airspace off their south coastline that actually extends over much of the adjoining Indian VECF/Kolkata FIR.

Aircraft intending to fly into, through, or within this new Bangladesh ADIZ must now obtain an ADC (Air Defence Clearance) number beforehand. Just file your flight plan, and they will send this to you by AFTN. Make sure you write it down – as they will ask you for it on HF before you enter their airspace.

If you don’t have AFTN access, you can get the number by calling +880-2890-1081 or emailing adnc@baf.mil.bd

The authorities in Bangladesh have released a scary sounding AIC on all this, which you can read in full here. What they fail to mention there, but have published by Notam, is that there are actually a bunch of airways over the ocean (P646, N895, M770, L524 and W112) where you won’t have to get this ADC number, unless you deviate towards the landmass of Bangladesh.

As the Notam clarifies:

A0032/18 NOTAMN Q) VGFR/QXXXX/IV/BO/AE/000/999/ 
A) VGFR B) 1802010001 C) PERM E) THE FLW AMDT/UPDATES ARE BROUGHT TO THE AIP-SUPP 01/2018: 
1. ACFT INTENDING TO OPR INTO, THROUGH OR WI BANGLADESH ADIZ SHALL OBTAIN ADC NR FM THE FLW CONTACT DETAILS. 
TELEPHE: +880 2 8901081 
FAX : +880 2 8901081 
E- MAIL: ADNC AT THE RATE OF BAF.MIL.BD 
AFTN : VGHSZQZX 
2. FLT OPR ON ATS RTE P646, N895, M770, L524 AND W112 SHALL NOT REQUIRED TO OBTAIN ADC NR UNLESS DEVIATED TOWARDS THE LAND MASS OF BANGLADESH. 
3. GUARD FREQ. 121.50 MHZ SHALL NOT BE USED TO CTC THE AIR DEFENCE UNIT. 
4. ARTICLE 'L' IN THE PROCEDURES FOR AIR DEFENCE CLEARANCE IN THE AIP-SUPP SHALL BE TREATED AS CNLD. 
5. FOR THE TIME BEING DOMESTIC FLT AND FLT OF STATE ACFT AND GENERAL AVIATION ACFT OF BANGLADESH SHALL NOT BE REQUIRED TO OBTAIN ADC NUMBER.

So you won’t need an ADC number on those airways, but for everywhere else in that big red ice-pick-shaped chunk of airspace, you’ll need to get authorisation. As the Bangladesh AIS office politely warn in their AIC: “Aircraft flying without a valid ADC number or failing to comply with any restriction or deviating from flight plan will be liable to interception by Bangladesh Air Force Interceptor aircraft according to ICAO Standard Interception Procedure.”

US 737 tests the China ADIZ

China: Go away quickly please
US Aircraft: Nope
China: Go away quickly!
US Aircraft: No!

The US is doing us all a huge favour at the moment. In fact, it’s been providing this service to the world for some time.

Every so often, a country extends its borders a little too far – outside the normal 12nm limit, for example. China has been busy. They’ve been building some things in the South China Sea. Islands, in fact. And on those islands they’ve built runways, control towers, and big radars. Naturally, they confirmed last Friday that they are for civilian use only. Hmmm.

So the US dusts off an airplane and knocks on the door. Flies around for a bit. Sees what’s going on. And reminds the country that international waters are just that. They publish a list each year of where they’ve done this. Worth a read.

In 2013 they popped up an ADIZ. And made everyone passing through it copy their Flight Plans to Beijing. In principle, ADIZ’s are a pretty good idea. The normal 12nm isn’t really much time for the military to figure out if you’re coming to bomb them. Especially on the weekend.

But you can’t tell airplanes to get out of an ADIZ. It’s an Identification Zone, not an Intercept Zone. So, normally ADIZ’s require you to squawk something and have a Flight Plan.

That much is OK. But China has been warning aircraft to get out of ‘their airspace’. And it’s not. This 737 (aka P-8 Poseidon) went for a nosey.

These operations help us all operating internationally to have less rules to worry about. Which is good.

Initially, most abided by the 2015 ADIZ rules. In 2016 that adherence quietly eroded. And China quietly didn’t care too much. It did threaten a second ADIZ in the South China Sea, but since the first one didn’t really take off, they probably won’t.

It’s part of a bigger diplomatic game. Interesting to watch, though.
