Windshear Warning alerts are given if a decreasing headwind
(or increasing tailwind) and/or a severe downdraft exceed a
defined threshold. These are characteristic of conditions
within or exiting an encounter with a microburst.
Windshear Warning results in illumination of red Windshear
Warning lights and an aural siren followed by the message
"WINDSHEAR, WINDSHEAR, WINDSHEAR". The lights
remain on for as long as the aircraft is exposed to conditions in
excess of the warning alert threshold. The aural message will
not repeat unless another separate windshear event is
encountered. The threshold is adjusted as a function of
available climb performance, flight path angle, airspeeds
significantly different from normal approach speeds, and
unusual fluctuations in Static Air Temperature (typically
associated with the leading edge of a microburst). The
Windshear Warning envelope is illustrated in the figure shown
on page 23.
Mode 7 Windshear alerting is active under the following
conditions:
• During takeoff; from rotation until an altitude of 1500 feet
AGL is reached,
• During approach; From an altitude of 1500 feet down to
10 feet AGL,
• During a missed approach; until an altitude of 1500 feet
AGL is reached.
