Update March 4:
Local agents report that ATC services are back to normal in Myanmar, as most ATC staff have returned to work. Operators overflying the VYYF/Yangon FIR should therefore be getting normal ATC service again now, and the Contingency Procedures are no longer in effect, but be on alert for the situation to change quickly.
Story from Feb 13:
Myanmar is no longer providing ATC service to overflights, due to lack of ATC staff.
Thousands of people across the country are taking part in nationwide strikes and protests against the military who overthrew the government at the start of February, and some ATC staff have joined in.
Local sources estimate that 70% ATC and 80% AIS staff are on strike, with very limited operations at NOTAM offices.
ATC service is still being provided at VYYY/Yangon, the country’s main airport, which remains open for arrivals and departures.
But for overflights of the country (the VYYF/Yangon FIR), all operators now have to follow the Contingency Procedures:
- 15 minute separation will be applied to all overflights
- You can only transit the airspace via specific waypoints, airways, and at certain flight levels.
Here are the VYYF/Yangon Notams that carry the announcement:
A0038/21 - DUE TO DISRUPTION OF ATS IN YANGON FIR ALL ACFT ARE ADVISED THAT THE MYANMAR INT'L CONTINGENCY PLAN FOR ACFT INTENDING TO OVERFLY THESE FIRS IS IN EFFECT.FLIGHT PLANING MUST BE IN ACCORDANCE WITH THE CONTINGENCY ROUTES LISTED AND FL ASSIGNMENT.PILOTS MUST STRICTLY ADHERE TO THE CONTINGENCY PROCEDURES.ONLY APPROVED INT'L FLIGHTS ARE PERMITTED TO OVERFLY MYANMAR AIRSPACE.(RMK- YANGON INT'L AIRPORT APP AND TWR CONTROL SERVICE AVBL FOR ALL ARR/DEP TRAFFIC. 08 FEB 12:28 2021 UNTIL 28 FEB 23:59 2021.

From the Myanmar ATS Contingency Plan. Click image to download.
Following the coup on Feb 1, the Myanmar Military declared a state of emergency and assumed control. Airports across the country were briefly closed, but a Notam issued on Feb 3 declared they were all open again. The strikes and protests started up on Feb 6, and show no signs of stopping anytime soon – despite a ban on large public gatherings and night-time curfews imposed by the military.
The VYYF Notams say that the current airspace restrictions will remain in place until Feb 28, but given the volatile situation on the ground right now, this could well get extended. We will keep this page updated with the latest news as we get it.
You won’t find the full version of the Myanmar ATS Contingency Plan in their AIP yet – the Myanmar CAA have stored it elsewhere on their website. You can find it here.

No wonder I have been seeing some strange flight routings recently, avoiding Myanmar airspace. I had been wondering if that was a Burmese government directive or not. This helps clear it up. Anyway, some examples I saw were flights from Guangzhou, China, Hong Kong or even Japan bound for destinations in India, Sri Lanka, the Maldives and East Africa diverting from Bangkok via Ranong and then straight across the Andaman sea over the Andaman Islands, rather than going straight across northern Thailand and cutting across central Myanmar as would be the shortest route.
By contrast, middle eastern and European flights bound for/ex Bangkok/BKK or Saigon/Manila would still fly over Burmese territory, overflying Dawei. Ditto for Bangladesh/Indian routes bound for China/Hong Kong/Japan, which would overfly northern Myanmar (Mandalay, Myitkyina etc.)
Hello
Notam A0038/21 is now cancelled. Yangon ACC resumed normal.
hi how we give notification to Myanmar since no ATC is working. or only OVF permit is sufficeient
