• Note •
When the Anti-Ice System has been used, avoid touching the
airframe structure or windshield as they will be partially
covered with anti-ice fluid. Clean the anti-ice fluid from the
windshield and the porous panels as described in Section 8,

Section 5 - Performance
Airplane performance and stall speeds without ice accumulation are
essentially unchanged with the installation of the Ice Protection
System.
Significant climb and cruise performance degradation, range
reduction, as well as buffet and stall speed increase can be expected if
ice accumulates on the airframe. Residual ice on the protected areas
and ice accumulation on the unprotected areas of the airplane can
cause noticeable performance losses and stall speed increases even
with the Anti-Ice System operating.
Stall Speeds with Ice Accumulation
• Note •
Altitude loss during wings level stall may be 600 feet or more.
KIAS values may not be accurate at stall.

Enroute Climb Gradient with Ice Accumulation
• Note •
Climb Gradients shown are the gain in altitude for the horizontal distance traversed
expressed as Feet per Nautical Mile.
Fuel flow must be set to top of green arc for all takeoffs and climbs.
Cruise climbs or short duration climbs are permissible at best power as long as altitudes
and temperatures remain within those specified in the table.
For operation in air colder than this table provides, use coldest data shown.
Conditions:
• Power.................................................................................................... Full Throttle
• Mixture............................................................................................ Set Per Placard
• Flaps...........................................................................................................0% (UP)
• Airspeed .................................................................................... Best Rate of Climb
