Revision – 3.9.2
Emergency landing with retracted undercarriage
An emergency landing with the main wheel retracted is on principle not
recommended, because the potential energy absorption of the landing gear is
many times higher as compared to the fuselage shell.
Should the wheel fail to extend, the aircraft should be landed at a flat angle, with
flaps set at “L”' and without pan caking.
Landing against an obstacle
If there is the danger of the aircraft overshooting the boundary of the landing field
in mind, a decision whether or not to initiate a controlled ground loop should be
made at least 40 m (131 ft) away from the boundary:
o
If possible, always turn into the wind
o
As the wing tip is forced down, push the control stick forward simultaneously.
Emergency water landing
From experience gained from composite sailplane landings on water following
recommendations can be given:
Approach:
o
Landing pattern parallel to the shore
o
Undercarriage extended
o
Ventilation closed
o
Water ballast tank valves closed
o
Main switch OFF
Landing:
o
Touch down with minimum speed and airbrakes retracted.
