3.6
Spiral dive recovery
Apply rudder and aileron in opposite direction and carefully pull out of
the dive.
Spiral dive occurs only when spinning more than 3 turns with medium
C.G. positions, see sect. 4.5.12.
To prevent spiral dives intentional spinning should only be executed at aft
C.G. positions.
Recovery from unintentional spinning should be done immediately.
3.7
Recovery from unintentional cloud flying
Spins are not to be used to loose altitude. In an emergency, pull out the
dive brakes fully before exceeding a speed of 200 km/h and fly with max.
200 km/h (108 kts.) until leaving the cloud.
At higher speeds up to VNE, pull out the dive brakes very carefully be-
cause of high aerodynamic and g-loads.
3.8
Flight with asymmetric waterballast
If you suspect that the waterballast does not dump symmetrically you
have to close the dump valves of the wingtanks immediately, to avoid
greater asymmetry.
Asymmetry can be verified by the necessary aileron deflection in straight
flight at low airspeeds.
When flying with asymmetric waterballast you have to increase the air-
speed, especially in turns, so that you can avoid a stall at all costs.
If the aircraft does enter a spin, you have to push the stick forward clearly
during recovery.
Fly the landing pattern and touch down aprox. 10 km/h (6 kts.) faster than
usually and after touch down control carefully the bank angle to avoid the
wing touching the ground too early.
3.9
Emergency wheel up landing
It is not recommended to execute a wheel up emergency landing, as the
energy absorption capability of the fuselage is much smaller than that of
the landing gear.
If the landing gear can't be extended touch down with small angle of at-
tack.
