Best Power Fuel Flow
The fuel flow values in the table below were demonstrated to obtain the
takeoff and climb performance presented in Section 5.
Takeoff
Power Check:
Check full-throttle engine operation early in takeoff run.
The engine should run smoothly and turn approximately 2700 RPM. Verify
all engine parameters are not in caution or warning ranges. Discontinue
takeoff at any sign of rough operation or sluggish acceleration. Make a
thorough full-throttle static run-up before attempting another takeoff.
For takeoff over a gravel surface, advance Power Lever slowly. This allows
the airplane to start rolling before high RPM is developed, and gravel will
be blown behind the propeller rather than pulled into it.
Flap Settings:
Normal and short field takeoffs are accomplished with flaps
set at 50%.
Takeoffs with 100% flaps are not approved.
Soft or rough field takeoffs are performed with 50% flaps by lifting the
airplane off the ground as soon as practical in a tail-low attitude. If no
obstacles are ahead, the airplane should be leveled off immediately to accel-
erate to a higher climb speed.
Takeoffs into strong crosswinds are normally performed with the flaps set
at 50% to minimize the drift angle immediately after takeoff. With the aile-
rons fully deflected into the wind, accelerate the airplane to a speed slightly
higher than normal while decreasing the aileron deflection as speed
increases then - with authority - rotate to prevent possibly settling back to
the runway while drifting. When clear of the ground, make a coordinated
turn into the wind to correct for drift.
