Pitot Heat should be turned ON for flight into IMC, flight into

• Note •
RPM drop must not exceed 150 RPM for either magneto. RPM
differential must not exceed 75 RPM between magnetos. If
there is a doubt concerning operation of the ignition system,
RPM checks at higher engine speeds will usually confirm
whether a deficiency exists.
An absence of RPM drop may indicate faulty grounding of one
side of the ignition system or magneto timing set in advance of
the specified setting.

Maximum Power Fuel Flow
Leaning for Takeoff and Maximum Climb is accomplished at full throttle
by leaning the mixture from full rich to the target fuel flow for the given
pressure altitude. The fuel flow values in the table below were
demonstrated to obtain the takeoff and climb performance presented
in Section 5.
• Note •
Excessively rich mixture will occur if the Mixture control is set to FULL
RICH above 7500 feet pressure altitude.

SR22 Normal Procedures
Takeoff
Power Check: Check full-throttle engine operation early in takeoff run.
The engine should run smoothly and turn approximately 2700 RPM.
All engine parameters should read in the green. 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.
• Note •
Fuel BOOST should be left ON during takeoff and for climb as
required for vapor suppression with hot or warm fuel.
