The following “representative surfaces” can be used for this check: (3)

Answer 7

wing leading edge and control surfaces

• Over head escape hatch
• L-1 Door

• Horizontal stabilizer

Question 8

Takeoff With De-icing/Anti-icing Fluids:

Is use of TO1 or TO2 permitted?

Is assumed temperature permitted?

What modifications are made to the takeoff profile?

Answer 8

Yes

No

None

Question 9

Cold Weather Takeoff Procedure:

Answer 9

Do the normal Takeoff Procedure with the following modifications:

When nacelle anti-ice is required and the OAT is 3°C or below, the takeoff must be preceded by a static engine run-up to a minimum of 60% N1 for approximately 30 seconds duration and confirm stable engine operation before the start of the takeoff roll

Question 10

Nacelle anti-ice must be ON during all flight operations when _____, except when _____

When operating in areas of possible icing, activate nacelle anti-ice _____ entering icing conditions

Answer 10

icing conditions exist or are anticipated

temperature is below –40°C SAT

before

Question 11

Do not rely on airframe visual icing cues before activating nacelle anti-ice. Use the temperature and visible moisture criteria because late activation of engine anti-ice _______

Answer 11

may allow excessive ingestion of ice

and result in engine damage or failure

Question 12

Do not use nacelle anti-ice when TAT is _____

Answer 12

above 10°C

Question 13

Avoid prolonged operation in _____ icing

conditions

Answer 13

moderate to severe

Question 14

During flight in moderate to severe icing conditions for prolonged periods or when fan icing is suspected due to _____, the fan blades must be cleared of any ice.

Do the following procedure every ______ on all
engines, one engine at a time: increase thrust to _____ for _____

Answer 14

high engine vibration

10 minutes

a minimum of 70% N1

10 - 30 seconds

Question 15

Ice accumulation on __(4)__ may be used as an indication of structural icing conditions and the need to turn on wing
anti-ice

Answer 15

flight deck window frames

windshield center post

windshield wiper arm

side windows

Question 16

The wing anti-ice system may be used as a de-icer or anti-icer. The primary method is to use it as a _____

Answer 16

de-icer

Question 17

Do not use wing anti-ice __(when)__

Wing anti-icing is not effective with _____

Answer 17

TAT is above 10°C

leading edge flaps extended

Question 18

When the temperature is colder than ISA, true altitude will be _____ than indicated altitude

Altimeter errors become significantly larger when the surface temperature approaches _____

Answer 18

lower

-30°C or colder

Question 19

An altitude correction due to cold temperature is not needed for the following conditions: (2)

Answer 19

• while under ATC radar vectors

* when maintaining an ATC assigned flight level (FL)

Question 20

Apply cold temperature altitude corrections to all published minimum ____, ____, and ____ altitudes, including _____

Advise ATC of the corrections

Answer 20

departure, enroute, approach
missed approach

• MDA/DA settings should be set at the corrected minimum altitudes for the approach

(The corrected altitude must always be greater than
the published minimum altitude)

Question 21

After prolonged operation in icing conditions with the flaps extended, or when an accumulation of airframe ice is observed, or when operating on a runway contaminated with ice, snow, slush, or standing water: _____

Answer 21

Do not retract the flaps to less than flaps 25 until the flap areas have been checked to be free of contaminants

Question 22

Consider doing the Cold Temperature Altitude Corrections Supplementary Procedure in the FCOM when altimeter errors become appreciable, especially where ____ exist near airports in combination with very cold temperatures of ____.

Also en route minimum altitudes and/or flight levels where ____. In some cases corrections may be appropriate for temperatures between ____
