FLIGHT PLANNING
1. FLIGHT PLAN ENTRIES - DD Form 1801 or ICAO standard
format. Flight plans must be filed at least 30 minutes prior to
proposed departure time to ensure clearance.
(AFFSA/AFFSA)
NOTE: To prevent misinterpretation of Item 10 in the Flight Plan,
it is emphasized that HF communication equipment is considered
as standard equipment for aircraft planning flight outside VHF
coverage in Sondrestrom FIR. Use of the letter "S" in Item 10 of
the Flight Plan therefore indicates the aircraft is HF as well as VHF
equipped.
(AFFSA/CL II NOTAM)
2. When there is reason to believe that the arrival report will
not reach the appropriate air traffic service unit within 30 minutes
after the estimated time of arrival, notification shall be made in
the flight plan concerning the time when such report may be
expected.
