Q

What is the significance of high swept wings versus less swept wings in ice accumulation?

A

The more swept the wing, the less time for the moisture to attach.

Q

Climbing through FL240 in visible moisture, the crew notices the TAT is - 22°C and the SAT is -45°C. What would be appropriate use of the ENG anti ice?

A

Engine anti ice may be turned OFF in this scenario. Engine anti ice is required when icing conditions exist or are expected except during climb or cruise when the SAT is below -40°C.

Q

Starting a descent out of FL350 with visible moisture, the TAT is -32°C and SAT is -53°C, what would be appropriate use of the ENG anti ice?

A

Engine anti-ice must be ON during the descent in icing conditions even if SAT is below -40°C

Q

Descending through 10,000ft, the pilots notice ice accumulation on the cockpit windshield blades. What should they do?

A

Turn on the WING anti ice. WING anti ice may either be used to prevent or remove ice accumulation from the wing leading edges. After takeoff, WING anti ice can be used after the aircraft is in a clean wing configuration. Ice accumulation can be detected by observing the ice indicator located between the two cockpit windshields or by observing the windshield wipers blades.

Q

Can the WING anti ice be used on the approach and landing?

A

Yes, but it should only be considered in severe icing because second segment climb performance could be affected if a go-around is performed.

Should a flight crew use TAT or SAT when determining whether to turn anti ice systems on?

A

Remember TAT indicates when to turn anti ice ON. SAT indicates when it may be able to be turned OFF.
