What is the lowest altitude to initiate a wind shear escape maneuver?

The lowest altitude to initiate a wind shear escape maneuver is 1,500 feet AGL. This altitude is established to ensure that pilots have sufficient altitude to execute a safe escape maneuver without being too low to the ground, where control and performance could be critically compromised.

Wind shear can occur unexpectedly and may lead to abrupt changes in airspeed or altitude. Initiating an escape maneuver at 1,500 feet AGL gives pilots a buffer to ensure they can adequately respond to the situation while retaining adequate control of the aircraft. It allows for necessary altitude to assess the flight conditions and perform the escape procedure safely, reducing the risk of an accident.

Choosing an altitude lower than this could lead to insufficient margins for recovery in case of severe turbulence or downdrafts associated with wind shear, increasing the risk of a controlled flight into terrain or other hazardous outcomes.
