CHAPTER TEN
BASIC FIGHTER MANEUVERS (BFM)
the direction opposite to the aileron input, due to adverse yaw, will be noticed. With an increase
in the aileron deflection, the aircraft will depart, with mild roll and yaw, followed by the nose
falling through. Recovery will occur quickly with neutral controls.
Break Turn Stall
The purpose of the break turn stall is to demonstrate the characteristics of a stall and correct
recovery techniques during a break turn. The stall will be conducted in a clean configuration at
250 KIAS. Upon completion of a clearing turn, the IP will roll into a level, 60 angle-of-bank
turn, while simultaneously reducing power to idle and extending the speedbrakes. The IP will
maintain altitude by varying AOB while maintaining approximately 3-4 Gs in the turn until the
aircraft stalls. Recovery will be initiated by simultaneously relaxing the backpressure, rolling
wings-level with the nose in the level flight attitude for the recovery airspeed, adding maximum
power, and retracting the speedbrakes. Crosscheck AOA and airspeed in order to prevent reentry
into the stall.
Steep Turn Stall
The purpose of this maneuver is to demonstrate the characteristics of a steep turn stall and its
proper recovery techniques. Steep turns are obviously extremely common during BFM
engagements. The steep turn stall will be conducted in a clean configuration at cruise airspeed
and power.
Upon completion of the clearing turn, the IP will roll into 80 angle-of-bank and attempt to
maintain altitude by increasing backpressure until the aircraft stalls. Rudder shaker should be
felt at 17-1/2 units AOA. Airframe buffet will occur shortly before the stall. The IP will initiate
recovery by simultaneously relaxing back pressure, leveling the wings, and adding maximum
power.
Zero Airspeed Departure
The purpose of this maneuver is to demonstrate the characteristics of an extreme nose-high low
airspeed departure. The maneuver will be conducted in a clean configuration. The IP will
initiate the maneuver by accelerating the aircraft to approximately 280 KIAS and commence a
4 G pull to 90 nose-up, by referencing the tip tanks perpendicular to the horizon. As the
airspeed decreases below 180 KIAS, the IP will reduce the power to idle and maintain a vertical
attitude. The airspeed will decrease to zero and the nose will fall forward or backward,
depending on the aircraft's exact attitude at the top of the maneuver. The rudder and elevator
may try to go full throw if the aircraft backs down on its tail.
As the airspeed decelerates below 120 KIAS during the initial climb, the student will ask the
pilot, "BELOW 120. DO YOU HAVE CONTROL?" The IP will answer "NO". The student
will direct recovery in accordance with the NATOPS out-of-control flight (OCF) recovery
procedure.
