3.12.2 Vibrations caused by the propeller or the propulsion system
Reasons for abnormal vibrations may be a local propeller-damage or a
malfunction of the engine or the drive system. It is recommended to REDUCE
the engine-RPM immediately. If the vibrations are not clearly reduced, the
following procedure is recommended:
1.
Throttle
IDLE
2.
Ignition
OFF
3.
Fuel-shut-off-valve
CLOSE
4.
Change to glider-configuration (see section 4.7.3.3)
5.
Prepare for an off-field-landing or landing on the next suitable airfield.
3.12.3 Flights in Icing-Conditions
Flights into icing-conditions are not allowed. If icing-conditions are met
unintentionally, ice can build-up on:
- Wings
- Tail-surfaces
- Flight-controls
- Propeller.
The risk of ice is greater at high altitudes. Additionally, ice on the cockpit-canopy
can reduce the visibility.
It is recommended to initiate an
emergency-descent
immediately to
reach a lower altitude:
1.
Throttle
IDLE
2.
Cowl-flaps
OPEN (to avoid freezing
locked in the CLOSED
position)
3.
Air-brakes
EXTEND
4.
Flight-controls
MOVE (to avoid freezing
locked)
Warning:
Ice on wings can increase the stall-speed remarkably and
can change flutter-behavior. The minimum-speed is also
increased by the additional weight.
