,
When applying power for take-off, move the throttle to tile full
open position slowly to avoid picking up loose stones, etc., with
the propeller. Apply back pressure
at
about
65-75
mph airspeed.
When the Mark
21
breaks ground, it will tend to "rock" into
a
nose-high attitude. To compensate for this tendency, relax
some of the elevator back pressure as the nose-wheel leaves
the ground. For best results and a smoother take-off, do not
allow the nose of the Mark
29
to lift above the horizon during
take-off. After
some practice, you will find that you can ivake
your snloothest takeoffs by applying elevator back pressure
as flying speed
is
approached and then slowly reducing the back
pressure as you feel the nose wheel lifting
from the ground,
This will allow the
aircrafi to
fly
smoothly from the runway
widlout any abrupt change in pitch attitude.
As soon as the
Mark
21
is
airborne and under good contl-01, per-
forrri the following procedures:
4.
Apply brakes to stop whesl rotation.
2.
Retrace the gear,
3.
Reduce the propeller rpm to 2550-2600.
4,
Retract the flaps.
5.
Establish climb-out attitude,
6.
Turn electric fuel pump to the "off9 position.
(Note fuel pressure indication to verify that the
engine
driven fuel pump will provide fuel pressure.)
An
enroute cliinb speed of 115-120 inph TAS
is
recommended
for improved cooling and good visibility. The speed for
maxirnuni
rate of climb is approxinlately
105
1.4s.
The speed for inaxiinuin
--
(obstacle clearance) is about 80 n?ph IAS. Recom-
mended power setting for clii:?bir.g is 2500 rpm and
25
inches
manifold pressure.

CHANGES
The following sequence is reconln~ended for increasing or
de-
creasing power settings.
