Section 3 – Emergency procedures
LANDING EMERGENCIES
10. LANDING EMERGENCIES
10.1 LANDING WITHOUT ENGINE POWER
In case of double engine failure both propellers should be feathered
to achieve maximum efficiency. Best glide speed is attained with flap
UP and equals V
Y
for current aircraft mass and air density altitude.
Refer to Section 5, Para. “Enroute Rate of Climb”.
Normal landing gear extension requires MASTER switch ON, an ef-
ficient battery and takes around 20 seconds.
LG selection should be appropriately anticipated when sure on fi-
nal.
Flap can be set to T/O or LAND when landing is assured on final to
reduce landing ground roll on short field.
Touchdown speed can be as low as 50 kt with flap down.
2. Flaps UP
3. Emergency landing field Select
Emergency landing strip should be chosen considering surface con-
dition, length and obstacles. Wind can be guessed by smoke plumes
direction and tree tops or grass bending. Select touchdown direction
according to the furrows of a plowed field, not across.
4. Safety belts FASTEN and tighten
5. Flaps Set when landing is assured
6. Landing gear control lever DOWN when landing is assured
To reduce landing gear extension time, evaluate use of emergency
control system which requires about 20 sec.
