2.
Aggressively apply maximum thrust to ensure maximum acceleration and performance. To ensure maximum thrust is obtained with minimum delay, an overshoot to the mechanical stops is recommended until positive indications of recovery are confirmed. Positive indications of recovery include:
A. Altimeter and IVSI indicate level flight or a climb; and
A. Airspeed stable or increasing; and
B. No stick shaker warning.
Note: If positive indications of recovery are confirmed while advancing the throttles to the mechanical stops, the power setting for continuous recovery to normal flight parameters may be limited to maximum rated thrust (i.e., go-around thrust) to avoid unnecessarily exceeding engine limitations.
3.
Rotate initially toward a 15 degree pitch attitude at normal rotation rate. Stop rotation immediately if stick shaker or buffet should occur. Roll wings level if in a turn to provide maximum lifting force.
4.
Disregard or turn off the flight director.
5.
Monitor vertical speed, attitude, and altitude. If the aircraft develops a sink rate, increase pitch attitude smoothly and in small increments to achieve zero or positive vertical path. Always respect stick shaker and use intermittent stick shaker as the upper limit for pitch attitude.
6.
Do not change flap, gear, or trim position until terrain contact and/or loss of airspeed is no longer a factor.
Note: After liftoff or initiation of a Go-Around, adjust pitch to achieve a positive vertical flight path. Although exact criteria cannot be established, a target pitch attitude of 15 degrees should provide a positive vertical path. Keeping a positive or zero rate of climb is the major objective. Airspeeds below normal must be accepted at least temporarily. Control pitch attitude in a smooth, steady manner to avoid overshooting the attitude at which stall warning is initiated. Heavy and unusual control column forces (up to 30 lbs) may be required.
Speed is the least important item. If the pilot attempts to regain lost airspeed by lowering the nose, the combination of decreasing airspeed and decreasing pitch attitude produces a high rate of descent. Unless this is countered by the pilot, a critical flight path control situation may develop rapidly.
7.
The pilot not flying should focus attention on vertical path, altitude, and pitch attitude. Inform the pilot flying of impending and negative vertical speeds by a callout of “SINK RATE.” The pilot flying should focus attention on pitch attitude and flying the airplane.
8.
Windshear ends when the tailwind component stops increasing.
Crew Coordination
The pilot flying should focus attention on flying the airplane. In a windshear encounter, appropriate action should be taken in response to callouts.
The pilot not flying should focus attention on airspeed, vertical speed, altitude, pitch attitude, glidepath deviation, and thrust. If significant deviations should occur, call them out immediately. In a windshear encounter, the pilot not flying should call aircraft trends such as “CLIMBING” or “SINKING” accompanied by radio altitude (AGL).
Pilot Reports
As soon as possible, report the encounter to the tower or controlling agency. The aircraft following might not have the performance required to recover from the same windshear encounter. The windshear may also be increasing in intensity making flight through it even more dangerous.
The pilot report should contain the following information:
.
Specifically state either GAIN or LOSS of airspeed.
.
Magnitude of GAIN or LOSS.
.
Altitude at which shear was encountered.
.
Location of shear with respect to runway in use.
.
Aircraft type.
.
Use the term PIREP to encourage rebroadcast of the report to other aircraft.
Critical remarks establishing severity such as ...MAXIMUM THRUST REQUIRED, ...ALMOST CONTACTED TERRAIN, ETC. are also helpful.
PREDICTIVE WINDSHEAR SYSTEM
Introduction
FAR 121.358 requires installation of an airborne windshear warning and flight guidance system, an approved airborne detection and avoidance system, or an approved combination of these systems. Since 1990 Continental in association with Allied Signal Corporation has participated in the development of the RDR-4B Forward Looking Windshear Detection / Avoidance Weather Radar System.
