Operational Navigation Flight Training Instruction
Routes in the Training Command
ROUTES IN THE TRAINING COMMAND
All pertinent regulations, i.e. FAR 91 and OPNAVINST 3710 apply to all routes flown within the
conterminous U.S. The only waiver applicable to flying a military training route within the U.S. is the 250
knot airspeed restriction below 10,000 ft MSL. This waiver exists while operating within the route’s lateral
and vertical limits.
WEATHER
Training Command Operational Navigation missions will not be flown unless weather is above minima and
forecast to remain so. Weather minima for IR and VR routes are 3,000 ft ceiling and 5 nm visibility on the
low-level portion of the route. Two plane road reconnaissance requires 8,000 ft and 5 nm visibility.
PLANNED AIRSPEED
All ONAV flights will be planned for 360 knots and 45 degrees AOB.
ALTITUDE
The minimum altitude for CNATRA aircraft is 500 AGL. Never violate the route minimum altitude. For
field departure and recovery, use altitudes published for the route or choose the best altitude for fuel
efficiency.
AREAS OF AVOIDANCE:
1. Do not overfly airports or their control zones. Avoid uncontrolled airstrips by 3 miles if you are below
1500 AGL. (FLIP AP/1B)
2. Over any congested area of a city, town, or settlement, or over an open-air assembly of persons, you
must remain 1,000 ft above or 2,000 ft horizontally from the highest obstacle. (FAR 91)
3. Avoid noise sensitive-areas (e.g., breeding and poultry farms, resorts, beaches, national parks) by 1
mile if you are lower than 3,000 AGL. If it is necessary to overfly wild fowl habitations, maintain at
least 3,000 AGL. (FAR Part 91)
4. Do not fly into restricted areas without clearance from the controlling agency. (FLIP AP/1B)
5. You may not make simulated attacks on installations important to national defense. You may not
simulate attacks on refineries, chemical plants, and other potentially dangerous targets. On single-
plane ONav flight, attacks may be simulated by fleet experienced IPs only. Roll-aheads are
forbidden. Depending on local SOP, an angle-off pop-up may be demonstrated at the instructor’s
discretion.
