Maximum Power Fuel Flow

Target fuel flow is indicated by the top of a dynamically calculated green arc
displayed on the fuel gauge. Target fuel flow should be maintained at the
top of this arc by use of the mixture lever.
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.
