Takeoff

The engine is equipped with an altitude compensating fuel
pump that automatically provides the proper full rich mixture.
Because of this, the mixture should be left full rich for takeoff,
even at high altitude airfields. To ensure maximum power
output from the engine, verify that the hottest EGT is at least
1250° F. Lean engine, as required, if EGT's are less than
1250° F.
Power Check: Check full-throttle engine operation early in takeoff run.
The engine should run smoothly and turn approximately 2700 RPM.
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 using 0% are permissible, however, no
performance data is available for takeoffs in the flaps up configuration.
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
accelerate 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 ailerons 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.
Fuel BOOST should be left ON during takeoff and for climb as
required for vapor suppression with hot or warm fuel.
