Speed Caution
Airspeed is less than 95 KIAS - too low for effective Anti-Ice System
protection,
OR
Airspeed is greater than 177 KIAS and 204 KTAS - too high for
effective Anti-Ice System protection.
1. Airspeed....................................................MAINTAIN 95-177 KIAS
or less than 204 KTAS
Left/Right Anti-Ice Fluid Level Caution
L / R fluid quantities on Anti Ice - TKS block of ENGINE page is
“greyed out” and/or fluid quantity is marked with a “Red X”. The antiice
fluid sensing system has detected conflicting system information
regarding the fluid level in one of the reservoirs.
1. Revert to manual control of the fluid source to control the fluid level
quantity.
If ANTI ICE FLO or ANTI ICE PSI annunciates:
a. Switch to opposite tank.
b. WIND SHLD Push-Button.............................................PRESS

Stall Warning / AOA Heater Failure Caution
1. STALL VANE HEAT Circuit Breaker ....................................CYCLE
2. PITOT HEAT Circuit Breaker...............................................CYCLE
3. Icing Conditions ........................................................ AVOID / EXIT
4. Fly aircraft normally using airframe buffet as the stall warning. Ice
accumulations on the stall warning vane may result in unreliable
stall warning system operation.
Pitot Heat Off Caution
Displayed when system detects OAT is above 41°F (5°C) and Pitot
Heat Switch is OFF.
• Note •
Operation of Pitot Heat on hot days may annunciate the AOA
OVERHEAT Warning when flying at slow speeds. When air
temperatures are greater than 41°F (5°C), operation of Pitot
Heat is at discretion of the pilot. If overheat warning is
annunciated, Pitot Heat should remain OFF
1. PITOT HEAT .............................................. ON, at pilot’s discretion
Dynamic Stall Speed Band Unavailable Advisory
Angle of Attack signal has failed. This signal is used to calculate and
display a dynamic stall speed awareness band (red band) on airspeed
tape. With a failed AOA signal, the low speed red band extends to a
fixed value of 61 knots.

Section 4 - Normal Procedures
• Caution •
Limit ground operations of Pitot Heat to 45 seconds.
Operation of Pitot Heat in excess of 45 seconds while on the
ground may cause excessive temperature on stall warning
transducer faceplate and surrounding wing skin.
Pre-Flight Inspection
A visual inspection and tactile check of the entire aircraft is required
before takeoff whenever conditions conducive to ground icing are
present. Dispatch into known icing conditions is prohibited if porous
panels do not fully “wet-out” or persistent annunciation of any Anti-Ice
System CAS messages.
System priming is only necessary if planning to enter Forecast Icing
Conditions or Instrument Meteorological Conditions (IMC) and OAT is
less than 41°F (5°C).
