MODEL TR182
Full power runups over loose gravel are especially harmful to pro-
peller tips. When takeoffs must be made over a gravel surface, it is very
important that the throttle be advanced slowly. This allows the airplane to
start rolling before high RPM is developed, and the gravel will be blown
back of the propeller rather than pulled into it. When unavoidable small
dents appear in the propeller blades they should be corrected immediately
as described in Section 8 under Propeller Care.
After a manifold pressure of 31 inches Hg is obtained, adjust the
throttle friction lock clockwise to prevent the throttle from creeping from a
maximum power position. Similar friction lock adjustment should be
made as required in other flight conditions to maintain a fixed throttle
setting.
WING FLAP SETTINGS
Normal takeoffs are accomplished with wing flaps 0° to 20°. Using 20°
wing flaps reduces the ground run and total distance over an obstacle by
approximately 20 per cent. Flap deflections greater than 20° are not
approved for takeoff.
If 20° wing flaps are used for takeoff, they should be left down until all
obstacles are cleared and a safe flap retraction speed of 70KIAS is reached.
To clear an obstacle with wing flaps 20°, an
obstacle clearance speed of 59
KIAS should be used.
Soft field takeoffs are performed with 20° flaps by lifting the airplane
off the ground as soon as practical in a slightly tail-low attitude. If no
obstacles are ahead, the airplane should be leveled off immediately to
accelerate to a safer climb speed.
With wing flaps retracted and no obstructions ahead, a climb-out speed
of 80 KIAS would be most efficient.
CROSSWIND TAKEOFF
Takeoffs into strong crosswinds normally are performed with the
minimum flap setting necessary for the field length, to minimize the drift
angle immediately after takeoff. With the ailerons partially deflected into
the wind, the airplane is accelerated to a speed slightly higher than
normal, and then pulled off abruptly to prevent possible settling back to
the runway while drifting. When clear of the ground, make a coordinated
turn into the wind to correct for drift.
LANDING GEAR RETRACTION
Landing gear retraction normally is started after reaching the point
