INSTRUMENT ROUTES (IR ROUTES)
Comply with FLIP AP/1B, local letters of agreement, and in-flight clearances.
VISUAL ROUTES (VR ROUTES)
Same as IR routes. Normally, you will contact the controlling ARTCC to cancel the IFR portion of
your flight plan and receive clearance to descend for route entry. Contact the nearest FSS
(255.4 MHz) and provide your call sign, route number, entry point, times in Zulu for entry and exit,
number of aircraft, type of aircraft, true airspeed, and altitude for route of flight. Check sectional and
FLIP publications for the correct FSS for route entry and exit (if different). If no response is received
from the FSS, transmit in the blind. This will alert other potential route users in the area. Monitor
255.4 en route, and fly the route as filed. At exit, check off the route with FSS and contact Center
(ARTCC) to resume your IFR flight plan.
