grossly out of trim as the vertical air columns change veloc-
ity and direction. If necessary to avoid excessive airspeeds,
lower the landing gear.
WIND SHEAR
Wind shears are rapid, localized changes in wind direction,
which can occur vertically as well as horizontally. Wind
shear can be very dangerous to all airplanes, large and
small, particularly on approach to landing when airspeeds
are slow.
A horizontal wind shear is a sudden change in wind direction
or speed that can, for example, transform a headwind into a
tailwind, producing a sudden decrease in indicated airspeed
because of the inertia of the airplane. A vertical wind shear,
is a sudden updraft or downdraft. Microbursts are intense,
highly localized severe downdrafts.
The prediction of wind shears is far from an exact science.
Monitor your airspeed carefully when flying near storms,
particularly on approach. Be mentally prepared to add power
and go around at the first indication that a wind shear is
being encountered.
WEATHER RADAR
Airborne weather avoidance radar is, as its name implies,
for avoiding severe weather--not for penetrating it. Whether
to fly into an area of radar echoes depends on echo inten-
sity, spacing between the echoes, and the capabilities of
you and your airplane. Remember that weather radar
detects only precipitation drops; it does not detect turbu-
lence. Therefore, the radar scope provides no assurance of
avoiding turbulence. The radar scope also does not provide
assurance of avoiding instrument weather due to clouds and
fog. Your scope may be clear between intense echoes; this
clear area does not necessarily mean you can fly between
the storms and maintain visual sighting of them.
