DITCHING
Prepare for ditching by securing or jettison heavy objects in the luggage compartment. To
protect the faces of the occupants, obtain folded coats or cushion ready at hand. Send
"Mayday" and state the position and intentions on the frequency 121.5 MHz
.
1)
Plan the approach into the wind when there is strong wind and rough seas. In case of
strong swells and light wind, fly parallel to the swells.
2)
Airspeed 65mph (56 Kts).with 40° flaps and engine power adjusted for descent of 300
ft/min
3)
Doors unlatch
4)
Touchdown at level attitude with adjusted rate of descent. Do not try to flare off as it is
difficult to estimate altitude above the water
5)
At touch down protect the face with cushion or folded coat.
6)
Evacuate the aircraft thought the cabin doors. If necessary open the windows and flood
the cabin for pressure equalization so that the door can be opened
7)
Inflate lifejackets or dinghies (if available) only after leaving the cabin. You cannot count
on the plane to be floating for more than a few minutes.
INADVERT ICING ENCOUNTER
A flight into know icing conditions is forbidden. However, if unexpected icing occurs;
Pitot heat "ON" (if installed).
1)
2)
Turn back of change flight altitude to obtain an outside air temperature that is less
conductive to icing
3)
Pull the cabin heat control full out to obtain maximum defroster air temperature. For
greater airflow at reduced temperatures, adjust the cabin heat as required
4)
Increase engine speed to minimize icing in propeller
5)
Watch out for the signs of induction air filter icing and use carburetor heater if needed. An
unexpected loss of engine power could be a sign of carburetor or air filter icing
6)
Plan a landing at the nearest airport. With an extremely rapid ice buildup, select suitable
off airport landing site
7)
Witch ice built-up of more than 0,5 cm in the wing leading edges be prepared for
significantly higher stall speed
8)
Leave the wing flaps retracted. With severe ice build-up on the horizontal tail, the change
in wing wake airflow direction caused by wing flap extension could result in a loss of
elevator effectiveness.
9)
Open the left window and if practical scrape ice from a portion of the windshield for
visibility in the landing approach
10) Perform a landing approach using a forward slip, if necessary, for improved safety
