Note: The following are indications the airplane is in windshear:
• windshear warning (two-tone siren followed by
“WINDSHEAR,WINDSHEAR,WINDSHEAR”) or
• unacceptable flight path deviations.
Note: Unacceptable flight path deviations are recognized as
uncontrolled changes from normal steady state flight conditions
below 1000 feet AGL, in excess of any of the following:
• 15 knots indicated airspeed
• 500 FPM vertical speed
• 5 degrees pitch attitude
Pilot Flying Pilot Monitoring
• Maneuver as required to avoid the windshear.

• 1 dot displacement from the glideslope
• unusual thrust lever position for a significant period of
time.

MANUAL FLIGHT
• Disconnect autopilot.
• Push either TO/GA switch.
• Aggressively apply maximum*
thrust.
• Disconnect autothrottle(s).
• Simultaneously roll wings level and
rotate toward an initial pitch
attitude of 15°.
• Retract speedbrakes.
• Follow flight director TO/GA
guidance (if available).
• Assure maximum* thrust.
• Verify all required actions
have been completed and
call out any omissions.

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 required to obtain positive
terrain separation. Smooth, steady control will avoid a pitch
attitude overshoot and stall.
Note: * Maximum thrust can be obtained by advancing the thrust levers
full forward if the EECs are in the normal mode. If terrain contact
is imminent, advance thrust levers full forward.
Note: ** If TO/GA is not available, disconnect autopilot and
autothrottle(s) and fly manually.
WARNING: *** Severe windshear may exceed the performance
capability of the AFDS. The pilot flying must be
prepared to disconnect the autopilot and autothrottle(s)
and fly manually.
Pilot Flying Pilot Monitoring
AUTOMATIC FLIGHT
• Press either TO/GA switch.**
• Verify TO/GA mode annunciation.
• Verify thrust advances to GA
power.
• Retract speedbrakes.
• Monitor system performance***.
• Assure maximum* thrust.
• Verify all required actions
have been completed and
call out any omissions.
• Do not change gear or flap
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.
