pump if left engine
is
out). If enough altitude has been reached
for reaching the airport with the gear extended, leave the landing
gear in the down position.
d. Maintain a best rate of climb airspeed of 102 MPH.
e. Trim directionally with rudder trim.
f . As the airport
is
approached for landing,
reduce
power
on the good engine and gradually retrim with the rudder tab.
When it is obvious that the airport can be reached easily, lower
the landing gear and check the indicators to make sure it is
down and locked. Maintain a little extra altitude and speed
during the approach, keeping in mind that the landing should be
made right the first time, and that either undershooting or over-
shooting may require the use of full power on the good engine,
making control more difficult. Lower the flaps at the last moment
if desired.
NOTE
If the left engine is inoperative the gear and
flaps must be pumped down by hand.
3. Unfeathering:
It is not recommended that propeller feathering and unfeath-
ering be practiced on the ground because of
the excessive
vibraticn that occurs in the engine installation. In flight, feath-
ering should be practiced ooly to familiarize the pilot with the
proper procedures. To unfeather a propeller in flight, the fol-
lowing technique is recommended
:
a. Fuel -
"ON".
b. Ignition switches .;
"ON".
c. Electric fuel pump -
"OFF".
(prime if necessary)
d. Throttle - open 1/2
inch.
e. Prop control - full forward.
f. Mixture - full rich.
