PA-46-350P, MALIBU
SECTION 5 - PERFORMANCE
Climb speed should be increased to 130 knots when icing conditions are
encountered during climb.
Cruise speeds are reduced approximately 5 knots when the surface boots
are installed.
Ice accumulation on the unprotected surfaces can
result in significant performance loss. During
cruise, loss of airspeed can be as much as 30
knots or more.
When icing conditions are encountered, loss of
cruise airspeed and increased fuel flow resulting
from higher than normal power settings to
maintain altitude will reduce the aircraft range
significantly. The use of an alternate airport
should be considered if fuel quantity appears
marginal.
If cruise airspeed drops below 130 knots in icing
conditions increase power to maintain 130 knots.
If maximum continuous power is required to
maintain 130 knots immediate action should be
taken to exit icing conditions.
For additional general information on inflight
icing refer to FAA Advisory Circular 91-51,
Airplane Deice and Anti-ice Systems.
