Ice Protection Flashcards
The Ice Detection System is composed of…
One ice detector providing an ice signal when and as long as ice is detected on the sensing element.
How much ice is required on the ice detector to tirgger the Ice signal (mm) …
0.5 mm of ice buildup on the sensing element.
Ice Detection System is only an advisory system. The pilot has the primary responsibility for detecting icing conditions through visual cues and activating ice protection systems.

Which five aircraft components are deiced using electrical heating?
- Stall warner
- Pitot Tubes
- Windshield
- Propeller Blades
- Air intake
Which ice protection system mode is signified by the color blue?
The system is activated automatically.
Which ice protection system mode is signified by the color green?
The system is activated manually.
Which ice protection system mode is signified by the color White?
The system is OFF.
Which ice protection system mode is signified by the color red?
The system is FAILED.
What is the difference between AUTO and MAN ice protection modes?
AUTO: ice is detected, all ice protection automatically activated.
Note: “ICE DETECTED” is displayed in the CAS window.
MAN: all deicing systems turn ON and can be activated/deactivated individually.
For a take-off WITHOUT icing conditions, what mode should the de-icing system be set?
AUTO (Blue)
INERT SEP - ON (Green)
PITOT HEATL/R & STALL HRT - ON (Green)
For a take-off WITH icing conditions, what mode should the de-icing system be set?
MAN (Green)
INERT SEP - ON (Green)
AIRFRAME DE ICE - ON
PROP DE ICE - ON
WIND SHIELD - ON
PITOT HEATL/R & STALL HRT - ON (Green)
When switching the ice protection system from MAN to AUTO pilot action is required to set the INERT SEP to…
pilot action is required to set INERT SEP ON.
For approach and landing WITHOUT icing conditions the ice protection system should be in which mode?
AUTO (Blue)
INERT SEP - ON (Green)
PITOT HEATL/R & STALL HRT - ON (Green)
Memory Items:
- AT . . . . Disconnect
- TRQ . . . . Reduce
- Fly the airplane
- THROTTLE . . . . Actuate
To vary RPM within operating range
Memory Items:
Leave icing conditions as soon as possible.
Memory Items:
- Avoid icing conditions
What does this CAS message indicate?
Indicates thats icing conditions have been detected by the ice detector and all DE ICING SYSTEMS have been automatically activated.
What does this CAS message indicate?
Indicates a failure of the ice detector or of the DE ICE SYSTEM panel printed circuit.
Severe icing conditions If one or more of these visual cues exists, immediately request priority handling from air traffic control to facilitate a route or an altitude change to exit the icing conditions.
- Unusually extensive ice accumulation on the airframe and windshield in areas not normally observed to collect ice.
- Accumulation of ice on the upper surface of the wing aft of the protected area.
ICE signal corresponds to…
…the elementary detection of 0.5 mm of ice buildup on the sensing element.
Heating of pitots and stall warning sensor system condition CAS messages:
Wing and tail boot system must be activated…
- at first sign of ice formation anywhere on the aircraft, and
- continued in automatic mode or manually cycled to minimize the ice accretions on the airframe.
Wing and tail boot system may be deactivated…
…only after leaving icing conditions and after the airplane is determined to be clear of ice.
The pilot must activate manually the ice protection systems as…
Prior to entering icing conditions or when icing conditions are identified.
The Ice Detection System is only an advisory system.
