Review of FLIP and Publications
Listed by state and areas within the state.
Route And Area Restrictions
Listed by state and/or area. Flight hazards and route and area restrictions are not found elsewhere in the
Supplementary Airport Remarks
Listed alphabetically by airport name as in the enroute supplements. As the name implies, this contains
supplementary information of a semipermanent nature too lengthy to be contained in the IFR or VFR
Prior to any cross-country flight and before checking the NOTAM box on the DD-175, Flight Hazards,
Route and Area Restrictions, and Supplementary Airport Remarks should be consulted.
Preferred IFR Routes
A system of preferred routes has been established to guide pilots in planning their route of flight, to
minimize route changes during the operational phase of flight, and to aid in the efficient orderly
management of air traffic, using federal airways. The preferred IFR routes are designed to serve the
needs of airspace users and to provide for a systematic flow of air traffic in the major terminal and enroute
environments. Cooperation by all pilots in filing preferred routes will result in fewer traffic delays and will
better provide for efficient departure, enroute, and arrival air traffic service.
The preferred routes are divided into low and high altitude structures (the division, of course, is 18,000 ft).
The high altitude list shows terminal to terminal routes; on some high altitude routes, low altitude airways
are included as transitional routes.
VOR Receiver Checkpoints
A listing of facilities that are available for operational checks of airborne VOR equipment. Military bases
normally designate a specific ground point for checking the accuracy of aircraft TACAN receivers. The
tolerances for the ground check are similar to VOR within plus or minus 4 degrees of the designated radial
and within one-half mile or 3 percent of the distance to the facility, whichever is greater. See GP
paragraph 5-44 for additional information.
