Preflight

e. Pilots are encouraged to give their departure

times directly to the FSS serving the departure airport

or as otherwise indicated by the FSS when the flight

plan is filed. This will ensure more efficient flight

plan service and permit the FSS to advise you of

significant changes in aeronautical facilities or

meteorological conditions. When a VFR flight plan

is filed, it will be held by the FSS until 1 hour after the

proposed departure time unless:

1. The actual departure time is received.
2. A revised proposed departure time is

received.

3. At a time of filing, the FSS is informed that

the proposed departure time will be met, but actual

time cannot be given because of inadequate

communications (assumed departures).

f. On pilot’s request, at a location having an active

tower, the aircraft identification will be forwarded by

the tower to the FSS for reporting the actual departure

time. This procedure should be avoided at busy

airports.

g. Although position reports are not required for

VFR flight plans, periodic reports to FAA FSSs along

the route are good practice. Such contacts permit

significant information to be passed to the transiting

aircraft and also serve to check the progress of the

flight should it be necessary for any reason to locate

the aircraft.

EXAMPLE−
1. Bonanza 314K, over Kingfisher at (time), VFR flight
plan, Tulsa to Amarillo.
2. Cherokee 5133J, over Oklahoma City at (time),
Shreveport to Denver, no flight plan.

h. Pilots not operating on an IFR flight plan and

when in level cruising flight, are cautioned to

conform with VFR cruising altitudes appropriate to

the direction of flight.

i. When filing VFR flight plans, indicate aircraft

equipment capabilities by appending the appropriate

suffix to aircraft type in the same manner as that

prescribed for IFR flight.

j. Under some circumstances, ATC computer

tapes can be useful in constructing the radar history

of a downed or crashed aircraft. In each case,

knowledge of the aircraft’s transponder equipment is

necessary in determining whether or not such

computer tapes might prove effective.
