Q

When must cowl anti-ice be turned on?

A

When the OAT is 10 degrees or lower and visible moisture of any form is present. (Fog with a visibility of less than 1 mile, rain, snow, sleet and ice crystals.

Cowl anti-ice must also be on when the OAT is less than 10 degrees C and the aircraft is operating on runways, ramps, taxiways where surface snow, ice, standing water or slush is present.

When in icing conditions or ICE is annunciated by the ice detection system, cowl anti-ice should also be turned on.

Q

When must wing anti-ice be turned on?

A

During final taxi prior to takeoff if OAT is 5 degrees or less, unless deicing/anti-icing fluids have been applied.

Wing anti-ice must also be selected and confirmed on when OAT is less than 5 degrees, and visible moisture is present, below 400ft AGL, or runway is contaminated, or there is precipitation.

Wing anti-ice system must also be turned on when ICE is annunciated by the ice detection system, and when in icing conditions and the airspeed is less than 230KIAS

A

60 seconds to engage the starter, followed by a cool down period of 10 seconds off for the first and second start attempt.

32
Q

What is the maximum time the engine starter may be engaged for? How much time must be allowed for the starter to cool off, assuming it is the THIRD or subsequent start attempt?
