Stalls should be taught
after the student has demonstrated the ability to control the glider in all
three axes. Teaching stalls prior to
this may cause the student anxiety while performing stalls, which will affect
their ability to recover from them in a timely fashion. Emphasize that the stall is a function of
angle of attack and may occur at any flight attitude regardless of speed.
Stalls, like every maneuver
have a setup, execution and recovery.
Setup for the maneuver by clearing the airspace while performing either
one 180 degree or two 90 degree turns.
Once clear, establish an approximate 50 mph IAS.
For forward stalls, bring
the nose of the glider up to an attitude where the student’s feet are on the
horizon. Maintain this attitude as the
glider slows by apply appropriate back stick pressure. When the stall breaks, center the stick and
let the glider build enough airspeed that recovery can be made smoothly with
minimum altitude lost and not enter into a secondary stall.
For turning stalls, begin a
shallow bank (approximate 10-15 degree) turn.
Bring the nose of the glider up to an attitude where the student’s feet
are on the horizon. Maintain this
attitude as the glider slows by apply appropriate back stick pressure and
opposite aileron to prevent the inside wing from dropping too much, making it
more difficult to stall (be careful not to level the glider or you will end up
with a forward stall). When the stall
breaks, center the stick and apply full opposite rudder. Let the glider build enough airspeed that
the stick can be used to level the wings and recovery can be made smoothly with
minimum altitude lost and not enter into a secondary stall.
Stalls with spoilers are
taught the same way with the exception that spoilers are deployed prior to
raising the nose of the glider, and closed as the stall breaks and the stick is
centered.
