SECTION III
THE
PIPER
COMANCHE
TAKE OFF
Just before take-~off the following should be checked:
1.,
Controls free
6.
Carburetor heat off*
2.
Flaps set
7.
Fuel on proper tank
3.
Tab set
8.
Electric fuel pump on
4.
Propeller get
9.
Engine gauges normal
5.
Mixture set (rich*)
10.
Door latched
*Carburetor induction system only.
In a smooth, steady motion of the throttle apply full power
allowing the aircraft to accelerate in the three point attitude
until the control surfaces become effective.
Then apply slight
back pressure on the control column to lift the nose wheel. Under
normal take-off conditions the Comanche will leave the ground
at about 65 MPH.
Trying to pull theaircraft off beforethe pro-
per speed is obtained will only prolong the take-off run.
After
the take-off has proceeded to the point at which a landirg could
no longer be made with the wheels down in the event of power
failure,
the gear should be retracted.
As soon as the gear is
up and sufficientaltitude has been gained, reduce power toclimb
setting.
For a minimum take-off run the flaps should be lowered to
the recommended
15 degrees.
With
the
flaps in this
position
the take-off run will be reduced
approximately
20 per cenmt.
Normally
flaps are
not
used during
crosswind
take-offs.
It is desirable to hold the nose wheel on the runway until a
higher than normal take-off
speed
is obtained,
then apply a
definite but not abrupt back pressure
to the control column
to
lift the aircraft from the runway.
Once
airborne,
set up the
required crab angle,
retract the gear, and continue the climb-
out.
During cold weather operation, when taking off from slush
or water covered runways, allowthe gear to remaindown lenger
than usual so that any slush remainingon the gears will freeze
and be broken away when the gear is retracted.
