Amplification
Do not takeoff with frost, ice, snow, or other contamination on
the fuselage, wing, stabilizers, and control surfaces.
Because this aircraft has a turbocharged system that
maintains 36.0 in.Hg manifold pressure for all takeoffs, the
mixture should be full rich for takeoff, even at high elevation
airports.
performance climb may cause excessive cylinder head
temperatures.
During cold weather operations, the engine should be properly
warmed up before takeoff. In most cases this is accomplished when
the oil temperature has reached at least 100°F (38°C). In warm or hot
weather, precautions should be taken to avoid overheating during
prolonged ground engine operation. Additionally, long periods of idling
may cause fouled spark plugs.
Pitot Heat should be turned ON for flight into IMC, flight into visible
moisture, or whenever ambient temperatures are 41° F (5° C) or less.
During the Magneto Check, 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.
