Cirrus SR20 and SR22 Flight Operations Manual
Section 4 Maneuvers
Autopilot Stall Recognition
The purpose of this maneuver is to identify the conditions when a stall
with the autopilot engaged may occur, recognize the affects of an
impending autopilot stall and learn the recovery procedure. Do not
exceed any autopilot limitations during this maneuver. The maneuver
is started by programming the autopilot for conditions it is not capable
of maintaining (excessive climb rate, insufficient power…) This
maneuver will not be executed to a full stall condition. Recovery will be
initiated at by disconnecting the autopilot and following the stall
recovery procedure.
AP Stall Recognition (Power Off)
Execution
• Execute clearing turns,
• Flaps 50%,
• Engage HDG and ALT modes on the autopilot,
> SR20 - 20% Power / 15" MP (approximately),
> SR22 - 15% Power / 12" MP (approximately),
> SR22 Turbo - 25% Power / 12" MP (approximately).
• Note •
Autopilot will increase the angle of attack to maintain altitude
sacrificing airspeed. Recovery will be performed at a speed no
lower than 80 KIAS as per the autopilot limitation.
Recovery
• Disconnect autopilot,
• Reduce angle of attack and level wings,
• Apply full power,
• Accelerate to V
Y
• Flaps 0%,
>SR20- 85 KTS,
>SR22- 80 KTS.
• Clear of terrain and obstacles,
• Positive rate of climb.
