Windshear Escape Maneuver
Note: Aft control column force increases as the airspeed decreases. In
all cases, the pitch attitude that results in intermittent stick shaker
or initial buffet is the upper pitch attitude limit. Flight at
intermittent stick shaker may be needed to obtain a positive
terrain separation. Use smooth, steady control to avoid a pitch
attitude overshoot and stall.
Note: * Maximum thrust can be obtained by advancing the thrust levers
to the takeoff or go-around limit. If terrain contact is imminent,
advance thrust levers full forward.
Note: ** Do not exceed Pitch Limit Indication.

MANUAL FLIGHT
• Disengage autopilot
• Push either TO/GA switch
• Aggressively apply maximum*
thrust
• Disengage autothrottle
• Simultaneously roll wings level
and rotate toward an initial pitch
attitude of 15 °
• Retract speedbrakes
• Follow flight director TO/GA
guidance (if available)**
• Verify maximum* thrust
• Verify all needed actions have
been completed and call out any
omissions.
AUTOMATIC FLIGHT
• Push either TO/GA switch***
• Verify TO/GA mode annunciation
• Verify GA* thrust
• Retract speedbrakes
• Monitor system performance****
• Verify GA* thrust
• Verify all needed actions have
been completed and call out any
omissions.
MANUAL or AUTOMATIC FLIGHT
• Do not change flap or gear
configuration until windshear is
no longer a factor
• Monitor vertical speed and
altitude
• Do not attempt to regain lost
airspeed until windshear is no
longer a factor.
• Monitor vertical speed and
altitude
• Call out any trend toward terrain
contact, descending flight path,
or significant airspeed changes.
