Section 3 - Emergency Procedures
A failure of the Anti-Ice System is any condition, observed or
suspected, in which the system fails to remove ice from protected
surfaces including the propeller, in addition to any Anti-Ice System
CAS failure annunciations. An unobserved failure may be indicated by
a decrease in airspeed, anomalous handling characteristics, or
airframe vibrations.
• Note •
Significant loss in cruise or climb performance may be an
indication of propeller ice accretions that are not visible to the
naked eye. Operation of the engine at 2700 RPM will help
shed ice in severe icing conditions.
• Caution •
Ice accumulations on protected areas are abnormal.
• WARNING •
With ice accumulations on the horizontal stabilizer leading
edge, flaps should remain retracted for landing and the
landing speed increased accordingly.
With asymmetrical ice accumulations on large portions of the
wing or horizontal stabilizer, avoid flight at speeds less than 95
KIAS.

Anti-Ice System Failure / Excessive Ice Accumulation
1. ICE PROTECT A and B Circuit Breakers.................................SET
2. Anti-Ice - TKS Quantity ....................SWITCH TO FULLEST TANK
3. WIND SHLD Push-Button ...................................................PRESS
a. Repeat operation of windshield pump to verify system is
primed properly as evidenced by anti-ice fluid exiting
windshield nozzles.
4. ICE PROTECT Mode Switch....................................VERIFY HIGH
5. PUMP BKUP Switch ................................................................. ON
If determined windshield pump is not priming:
6. Exit Icing Conditions Immediately.
7. Airspeed.................................................... 95 KIAS OR GREATER
Maintain a minimum airspeed of 95 KIAS or higher to stay above
pre-stall buffet. If unable to maintain this airspeed, allow altitude to
decrease in order to maintain 95 KIAS.
8. Minimum Approach Speed w/ Residual Ice (Flaps 50%)...88 KIAS
In severe icing conditions, it may not be possible to maintain
altitude or proper glide path on approach; in this case, it is
imperative that a safe airspeed be maintained, the stall warning
system may not function and there may be little or no pre-stall
buffet with heavy ice loads on the wing.
9. FLAPS.........................................................MINIMUM REQUIRED
When landing is assured, select the minimum flap setting
required, not to exceed 50%, and maintain extra airspeed
consistent with available field length. Do not retract the flaps once
they have been extended unless required for go-around.
