.
For optimum takeoff performance, use flaps 5, 10 or 15 unless
limited by obstacle clearance and/or climb gradient
.
Use the longest suitable runway provided it is clear of areas of
known windshear
.
Consider increasing Vr speed to the performance limited gross
weight rotation speed, not to exceed actual gross weight Vr + 20
knots. Set V speeds for the actual gross weight. Rotate at the
adjusted (higher) rotation speed. This increased rotation speed
results in an increased stall margin and meets takeoff performance
requirements. If windshear is encountered at or beyond the actual
gross weight Vr, do not attempt to accelerate to the increased Vr
but rotate without hesitation.
.
Be alert for any airspeed fluctuations during takeoff and initial
climb. Such fluctuations may be the first indication of windshear

.
Know the all–engine initial climb pitch attitude. Rotate at the
normal rate to this attitude for all non–engine failure takeoffs
Minimize reductions from the initial climb pitch attitude until
terrain and obstruction clearance is assured, unless stick shaker
activates
.
Crew coordination and awareness are very important. Develop an awareness of normal values of airspeed, attitude, vertical speed, and airspeed build–up. Closely monitor vertical flight path instruments such as vertical speed and altimeters. The pilot not flying should be especially aware of vertical flight path instruments and call out any deviations from normal
.
Should airspeed fall below the trim airspeed, unusual control
column forces may be needed to maintain the desired pitch
attitude. Stick shaker must be respected at all times
.
If windshear should be encountered near VR, and airspeed suddenly decreases, there may not be sufficient runway left to accelerate back to the normal VR. If there is insufficient runway left to stop, initiate a normal rotation at least 2000 feet before the end of the runway even if airspeed is low. Higher than normal attitudes may be needed to lift–off in the remaining runway
Approach and Landing
.
Use flaps 30 for landing.
.
Establish a stabilized approach no lower than 1000 feet above the airport to improve windshear recognition capability
.
Use the most suitable runway that avoids the areas of suspected windshear and is compatible with crosswind or tailwind limitations. Use ILS G/S, VNAV path or VASI/PAPI indications to detect flight path deviations and help with timely detection of windshear
.
If the autothrottle is disengaged, or is planned to be disengaged prior to landing, add an appropriate airspeed correction (correction applied in the same manner as gust), up to a maximum of 20 knots
.
Avoid large thrust reductions or trim changes in response to sudden airspeed increases as these may be followed by airspeed decreases
.
Crosscheck flight director commands using vertical flight path
instruments

. Crew coordination and awareness are very important, particularly
at night or in marginal weather conditions. Closely monitor the
vertical flight path instruments such as vertical speed, altimeters,
and glideslope displacement. The pilot not flying should call out
any deviations from normal. Use of the autopilot and autothrottle
for the approach may provide more monitoring and recognition
time.
Recovery
Accomplish the Windshear Escape Maneuver found in the Non–Normal Maneuvers section of this manual.
