Meteorology Review
(6) Significant differences between winds at
1,500-2,000 ft AGL and surface winds
(7) LLWAS (Low-Level Windshear Alert
System) alert
(8) PIREP of windshear or airspeed gain or
loss
NOTE: Although PIREPs are important to
alert other pilots of microbursts, microburst
intensity can change rapidly, so even
recent PIREPs may not reflect the true
strength of a microburst--listen to the
aircraft ahead or ask for PIREP information
from ATC. Report any airspeed
fluctuations of 5 kts or more as soon as
possible.

(1) Takeoff: delay departure
(2) Landing: delay approach or use alternate
runway/approach/airfield
d.
Response during landing
(1) Execute a missed approach immediately—
response time is critical
(2) Recognize that excess airspeed is neces-
sary to maintain flight beyond core of
microburst--don't pull power
(3) Report encounter to ATC as soon as
possible
NOTE: With proper technique, high
performance aircraft will be able to fly out of
some microbursts, but not out of all.
Avoidance is the best course of action but if
a microburst is encountered, recognition
and reaction prior to being caught “low and
slow” are the only safeguards.
