Question 13

Definition of icing

Answer 13

Icing conditions exist when:
• OAT on the ground and fortakeoff or TAT in-flightis 10°Cor belowand visible moisture in any form is present.
Visible moisture is a form of precipitation (e.g., clouds, fog with visibility of one mile
(1600 m) or less, rain, snow, sleet, or ice crystals).
• OAT on the ground and for takeoff is 10°C or below when operating on ramps, taxiways, or runways where surface snow, ice, standing water, or slush may be ingested
by the engines or freeze on engines, nacelles, or engine sensor probes.

Question 14

Engine Anti-Ice Operation - On the Ground

Answer 14

Engine anti-ice must be selected ON immediately after both engines are started and remain on during all ground operations when icing conditions exist or are anticipated, except when the temperature is below –40°C OAT.

Question 15

Engine Anti-Ice Operation - In Flight

Answer 15

Engine anti-ice must be ON during flight when icing conditions exist or are anticipated, except during climb and cruise when the temperature is below -40°C SAT. Engine anti-ice must be ON prior to and during descent in icing conditions, including temperatures below -40°C SAT.

Question 16

Operation in Ice Crystal Icing Conditions

Answer 16

Engine anti-ice must be ON when ice crystal icing conditions exist, even when the temperature is below -40°C OAT. Do not use anti-ice if OAT or TAT exceeds 10°C.

Note: Ice crystal conditions exist when in visible moisture and one or more of the
following indications are present:

• Amber or red weather radar returns below the airplane.
• Appearance of liquid water on the windshield at temperatures too cold for rain (the sound is different than rain).
• The autothrottle is unable to maintain the selected airspeed.
• TAT indication on EICAS stays near 0°C.
