Hi guys
A question for any Faa licenced guys.

What is the procedure for loss of comms if you have clear air Turbulence over the north pacific ocean(ie hawaii to Japan).

is it climb/descend 1000ft and turn off track by a certain distance?


Thanks for the answers and any reference if you have it

According to the Jeppesen High/Low chart 1/2 for the Pacific Ocean, if you are unable to continue the flight in accordance with the ATC clearance, and you can not obtain an amended clearance, you should turn at least 45 degrees right or left and offset 15nm. If unable to maintain the current altitude, you should select a final altitude that differs from the normal altitude by 500 ft if operating at or below FL410.

According to the chart this is excerpted from ICAO DOC 4444, SECTION 15.2, Special Procedures for In-Flight Contingencies In Oceanic Airspace.

Hope this helps. :ok:
