Proportionally opposite ailerons may help to maintain the plane of
turning.
After the sailplane turns its nose downward into opposite direction,
neutralize ailerons and rudder, so that the sailplane flies out
accurately into opposite direction (180°).
Recover gently without exceeding the load factors.
Lazy eight
Slightly push the control stick forward to reach entry speed not less
than 180 km/h IAS (97 KIAS, 112 mph) (recommended is 200 km/h,
108 KIAS, 124 mph). Gradually pull the control stick while
coordinately applying the ailerons and rudder to perform a climbing
turn in required direction. At a speed of 120 km/h IAS (65 KIAS, 75
mph) change to gliding at 180 km/h IAS (97 KIAS, 112 mph) and
gradually pull the stick while coordinately applying the ailerons and
rudder to perform opposite climbing turn. The trajectory intersection
is in the lowest point of the eight.
In steep turns, the following speeds, depending on load factor, and
degree of bank, should not be less than :
