The November Mega OpsChat – All the Links…



The November 24th “East/West-One-Day-Two-Calls” OpsChat Bonanza was great! Thank you to all who joined us, and those who shared some useful intel with the group.

Boy, did we cover a lot! The good news is if you missed the show, you can re-watch the recording here:

During the chat, we provided a bunch of links for each topic covered. If you weren’t quick enough to catch them at the time (we don’t blame you), here’s a little summary….

November Updates…


What? Baffling Notam issued declaring Greenland’s airports were closed.

What else? Panic not, a better one was then reissued, saying that you could still use Greenland’s airports for ETOPS and diversion alternates. We called them and they said that tech-stops and ferry flights are also allowed (although not listed in the Notam). They’ve basically just banned passenger flights, and don’t want people staying overnight.

What? You can now overfly Israel (as well as Jordan, Saudi Arabia and Bahrain).

What else? You need a local sponsor, should depart from an approved airport (but they do make exceptions) and need a permit.

Hong Kong

What? Strange ILS behaviour, especially on Runway 07R/25L. Pretty much down to antennas, terrain and Boeing AFDS…

What else? They have also updated their Covid entry restrictions for crew – it’s now slightly harder to get in.

What? When will you get in trouble for not having it.

– Europe: ADS-B is required from June 2023, but have your retrofit plan in by December 7 (unless your AoC is before 1995).
– US: ADS-B is required anywhere Mode C, or in the picture below.
– Rest of World: Above FL290, pretty much.

Where you need ADS-B in the US

North Atlantic Datalink Mandate

What? The North Atlantic Datalink Mandate (NAT DLM) is the thing that came into effect in Jan 2020, which meant that CPDLC was then required between FL290-FL410 throughout the entire NAT region. Simply put, you must be equipped with CPDLC and ADS-C if you want to fly between these flight levels.

And then what happened? Then Covid happened. Because of the resulting reduction in traffic they suspended this mandate, and it looks set to stay this way until the end of Feb 2021. Bottom line, aircraft which do not have CPDLC and ADS-C can continue to operate across the North Atlantic between FL290-410 until then.
