BASIC FIGHTER MANEUVERS (BFM)

Zero airspeed departure.

Cross control departure.

Adverse yaw departure.

TACAN Rendezvous.

Tail Chase demonstration (demo pursuit curves and guns envelope).

RTB.

Performance Characteristics Exercise

The purpose of the performance characteristics exercise is to demonstrate the performance

capabilities of the aircraft. The exercise will demonstrate timed turns, timed accelerations, as

well as instantaneous "G" available at different airspeeds.

The maneuvers will be demonstrated independent of the other aircraft. To initiate the exercise,

the section will divide the working area and take flight separation. At 15,000 feet MSL, the

following performance exercises will be demonstrated:

Timed acceleration from 200 to 300 knots straight and level at MRT.

2. Timed acceleration from 200 to 300 knots unloaded at "zero G". The timed accelerations

will demonstrate the advantage of unloading the aircraft for rapid energy addition.

Timed turn at 12 units AOA for 180 of turn maintaining 250 KIAS.

4. Timed turn at 15 units AOA for 180 of turn maintaining 250 KIAS. The timed turns will

demonstrate the higher turn rate available at 15 units AOA versus 12 units AOA. During the 15

unit AOA turn however, a loss of altitude will be the expected performance trade-off for the

increased turn rate performance.

Instantaneous "G" available at 200 knots.

6. Instantaneous "G" available at 250 knots. The instantaneous "G" comparison will

demonstrate the fact that as airspeed increases, available "G" increases.

1009. STALLS AND DEPARTURES

Numerous stalls and departures will be flown to demonstrate the edge of the aircraft's envelope.

During a BFM engagement, maximum performance from your aircraft will be demanded. The

stalls and departures will demonstrate aircraft performance and handling characteristics at the

"edge of the envelope". The tactical aircrew must be able to fly the aircraft to the limits of the

envelope in order to take full advantage of its capabilities. Therefore, it is likely the aircraft
