Definition

An airborne wind shear warning system is a device which identifies the presence of wind shear.

Description

Some systems detect a potentially severe windshear phenomena far enough in advance of the encounter, in both the takeoff/climbout profile and the approach/landing profile, to allow the pilot to successfully avoid the phenomena.

Other systems provide the pilot with timely warning and adequate flight guidance, in the event of severe wind shear, to fly a successful escape manoeuvre:

1. Approach/Missed Approach: using the maximum performance capability available without inadvertent loss of control, stall, and without ground contact.

2. Takeoff and Climbout: during the initial or subsequent climb segments using the maximum performance capability available without inadvertent loss of control or ground contact with excess energy still available.
