Approach to Stall–Clean
Flaps 0°
Entry
• Reduce power to idle
• Maintain altitude as speed decreases
At first indication of stall, simultaneously:
• Reduce angle of attack
• Thrust lever to takeoff power
• Level wings and accelerate out of stall
Before entry
• Flaps 0°
• Altitude 12,000
to 15,000 ft
Use trim
to reduce pressures
Recovery
• Adjust pitch attitude to maintain altitude
as airspeed increases
• Adjust airspeed to 180 kt
or as directed

Flaps 20°, 15° to 30° of Bank, Gear Down
Entry
• Reduce power to 60% N1
• Roll into turn 15 to 30°
• Maintain altitude
At first indication of stall, simultaneously:
• Wings level
• Reduce angle of attack
• Thrust levers to
takeoff power
• Level wings
and accelerate
out of stall
Before entry
• Gear down
• Flaps 20°
• Altitude 12,000
to 15,000 ft
Use trim to relieve
pressures to VLND20 +10
– but not below
Recovery
• Adjust pitch attitude
to maintain altitude
• Adjust airspeed to
180 kt or as instructed
As airspeed
increases
“FLAPS 8°”
Look up VLND20
and VAPP for airplane
weight with flaps 20°
“ABOVE

Approach to Stall
Landing Configuration
Entry
• Reduce power to 60% N1
• Maintain altitude until at VREF,
then descend 500 ft below
existing altitude and level off –
do not add power
At first indication of stall or buffet:
• Reduce angle of attack
• Thrust levers to takeoff power
• Level wings and accelerate out of stall
Before entry
• Gear down
• Flaps down
• Altitude 12,000
to 15,000 ft
As airspeed increases above VREF,
“ABOVE VREF”
• Maintain heading and altitude
• Increase airspeed to 180 kt
or as directed
“VAPP + 20”
