Operations personnel. Changes should be kept to a minimum and
given as much lead time as possible.
c. Filed flight plans remain within the system for two
hours from proposed departure times. After that, flight plans
must be re-filed with base operations.
d. Pre-filed routes
(1) Flight strips for pre-filed routes are not fed to
clearance delivery until thirty minutes prior to the proposed
departure time. If a flight plan is required before that time,
clearance delivery should be informed on initial contact of the
early departure request in order to "force" an early "print out"
of the clearance. When possible, this should be done via phone
call to base operations to avoid delays.
(2) NPA pre-filed routes containing terminal delays or
VFR segments are filed into the ATC system as a separate flight
plan for each segment. Pilots receiving ATC clearance via
stereo route codes which contain terminal delays or VFR portions
must obtain further ATC clearance prior to operating IFR on any
subsequent route segment. Pilots receiving ATC clearance via
stereo route codes which contain VFR portions shall consider
their initial IFR clearance limit to be the last fix prior to a
VFR route segment. It is recommended that further ATC clearance
be requested prior to commencing a practice approach at an enroute
terminal delay point to alert approach controllers of your
intentions and avoid departure delays.
(3) NPA pre-filed routes may be used to file stopover
flights to and from local area airports. This may be done by
placing both route codes in the route block of the squadron
flight schedule, (e.g. NPA-800/800R) and adhering to the on-deck
time stated in the route REMARKS. If actual on-deck time varies
by more than one hour from what is published, the stopover base
operations should be provided a revised departure time.
(4) Alternate pre-filed routes should be used (if
available) to preclude any delays in filing an alternate route
of flight airborne when the weather precludes the execution of
the next portion of the original flight plan. Base Operations
will schedule Alternate pre-filed routes for all routes that
have “A” or “B” stereo routes published (e.g. NPA-
500/500A/500B). Aircrew may activate the alternate route code
with ATC at the appropriate time. If the alternate route is
scheduled and not used, it will automatically drop out of the
system. No aircrew action is required. If a published
