41
Q

Anti ice system usage in flight?

A

Engine anti ice must be AUTO or ON during all flight operations when icing conditions exist or are anticipated, except when the temperature is below -40 degrees SAT.

42
Q

Icing conditions ground definition?

A

Icing conditions exist when the OAT on the ground and for the take off is 10 degrees 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.

43
Q

46
Q

VNAV operation restriction?

A

If levelling off within 2000ft after changing altimeter setting from QNE to QNH or QNH to QNE, do not use VNAV to execute the level off if QNH is less than 29.70in/1006 hPa. After the level off is complete VNAV may be re-engaged.

- Do not attempt to start APU in flight.
Additional for all types except -8
- The APU may be used to supply bleed air to air conditioning pack #2 for take off, provided the isolation values remain closed. If engine failure occurs, do not change air conditioning bleed configuration until flap retraction altitude has been achieved.
