4. Flight Plan

VFR Flights
a.
Except for operations in or penetrating an
ADIZ, a flight plan is not required for VFR flight.
REFERENCE
−
AIM, Chapter 5, Section 6, National Security and Interception
Procedures
b.
It is strongly recommended that a flight plan
(for a VFR flight) be filed with an FAA FSS. This will
ensure that you receive VFR Search and Rescue
Protection.
REFERENCE
−
AIM, Paragraph 6
−
2
−
6 , Search and Rescue, gives the proper method of
filing a VFR flight plan.
c.
To obtain maximum benefits from the flight
plan program, flight plans should be filed directly
with the nearest FSS. For your convenience, FSSs
provide aeronautical and meteorological briefings
while accepting flight plans. Radio may be used to
file if no other means are available.
NOTE
−
Some states operate aeronautical communications facili-
ties which will accept and forward flight plans to the FSS
for further handling.
d.
When a “stopover” flight is anticipated, it is
recommended that a separate flight plan be filed for
each “leg” when the stop is expected to be more than
1 hour duration.
