Icing Conditions on Ground and for Takeoff -
MCDU TO DATASET MENU - set to ENG when:
- SAT is 5C to 10C and visible moisture will be encountered up to 1,700’ AFE or:
- Operating on ramps, taxiways, or runways where surface snow, ice, standing water, or slush may be ingested by the engines, or freeze on engine nacelles, or engine sensor probes.
Icing Conditions on Ground and for Takeoff -
MCDU TO DATASET MENU - set to ENG when:
- SAT is less than 5C and visible moisture will be encountered up to 1,700’ AFE or,
- Operating on ramps, taxiways, or runways where surface snow, ice, standing water, or slush may be ingested by the engines, or freeze on engine nacelles, or engine sensor probes.
Icing conditions exist in flight whenever static air temperature (SAT) on the ground (taxi or takeoff), or the Total AirTemperature (TAT) in flight is:
Equal to or less than 10C and visible moisture in any form is present (such as clouds, fog with visibility of one mile or less, rain, snow, sleet, and ice crystals)
If either one or both ice detectors are failed,
The crew must set the mode selector to ON when icing conditions exist or are anticipated with a TAT of 10C or below with visible moisture.
Random Limitations: when the airplane is stopped on the ground,
The taxi and landing lights must be OFF
Random Limitations: for takeoff and in flight the taxi nose light must be:
Off.
How long should you wait after the GPU switch is pushed in, or the APU power is available before shutting down the engine(s)?
10 seconds
Minimum Flight Speed - All Altitudes, exceptions
Except as described in the normal/abnormal/emergency procedures, the airplane may never be operated below the “green dot” speed.

Must be used for all Cat I approaches
VOR flight director mode:
Is prohibited/inhibited. VOR navigation using the FD must be predicated on HDG mode and VHF (green) needles or LNAV mode (magenta).

Before stopping the APU after engine start:
- Engine N2 must be stabilized for 5 seconds, OR
2. Power transfer is confirmed on the Electrical Synoptic Page
Before starting the APU after an engine is shutdown:
- Wait for the engine to go below 30% N2
