STALLS AND UNUSUAL ATTITUDE RECOVERIES
Practicing stalls and unusual attitude recoveries will give you confidence and experience in recognizing
abnormal situations and in promptly taking the appropriate corrective action. You will perform these
maneuvers entirely on instruments.
STALLS
The stalls consist of recoveries initiated from two types of entries: clean and dirty. Prior to executing
these stalls, complete the stall and aerobatic checklist. You must begin all stalls at a minimum altitude of
10,000 ft AGL.
Clean
Clean stalls are performed with gear up, flaps/slats retracted, and speed brakes in, and they are initiated
at an airspeed of 200 KIAS. To commence the maneuver, reduce throttle to idle, extend the speed brakes
to assist in slowing down, retract the speed brakes at 150 KIAS, keep the wings level, and maintain
altitude. As the airspeed bleeds off, you will have to increase back stick pressure to hold altitude
constant, do not trim past 150 KIAS. Maintain altitude until you feel the rudder shaker, heavy buffet, and
obtain wing drop-off at stall. To recover, advance the throttle to MRT, retract the speed brakes, lower the
nose to attain 20-21 units AOA, and level wings. Hold 20-21 units AOA until you see a positive rate of
climb on the VSI and altitude trend indicator.
