Ice and Rain protection GROUND
The TO DATASET MENU on the MCDU must be set to ENG on in the following cases when OAT is between 5C and 10C and:
- if there is any possibility of encountering visible moisture up to 1,700 ft AFE
- when operating on ramps, taxiways, or runways where surfaces snow, ice, standing water or slush may be ingested by the engines, or freeze on engines, nacelles, or engine sensor probes
Ice and Rain protection GROUND
The TO DATASET MENU on the MCDU must be set to ALL on in the following cases when OAT is less than 5C and:
- if there is any possibility of encountering visible moisture up to 1,700 ft AFE

Prohibited
Ground Start Tailwind
When it is necessary to perform an engine start with tailwind, monitor N1 indication. When there is no positive increase of N1 indication before starter cut out 50% N2, the engine start must be mentally aborted.
Engine thrust
Take off with the automatic take off thrust control system ATTCS off is not authorized.
Crossfeed operations
If you crossfeed must be selected off during takeoff and landing.
APU General
Wait 30 seconds after the EICAS is energized to start the APU. Do not leave the aircraft unattended more than five minutes with the APU running SW. Simultaneous use of the APU bleed and the HP cart is prohibited.
Ice and Rain protection FLIGHT
The engine and wing anti ice systems operate automatically, in case of ice encounter when the ice protection mode selector is the AUTO position. When either one or both ice detectors are failed, the crew must set the mode selector to ON when icing conditions exist or are anticipated below 10° TAT with visible moisture.
Instrument, navigation, and communications
TAS, TAT, and SAT information are only valid above 60 kts. When transmitting in VHF1 the standby magnetic compass indication is not valid. Barometric altimeter minimum’s must be used for all cat one approaches. Prior to joining a publish segment of an instrument approach, verify the NAVAID identification visually displayed matches a chart being used. When the identification is not visually displayed verify the ID matches a chart being used.
Audio panels
Do not plug in dual prong and ANR 5 pin headset to the same Jack panel simultaneously. This may cause damage to the digital audio panels.
Enhanced ground proximity warning system EGPWS.
Navigation is not to be predicated on the use of the Terrain awareness system. The use of predictive EGPWS functions should be manually inhibited when landing at an airport that is not in the database to avoid unwanted alerts. The use of predictive EGPWS functions must be manually inhibited during QFE operations, when GPS data is unavailable or in operative. Press in the GED PROX TERR INHIB button to inhibit predictive EGPWS functions.
FMS limitations
RNAV (GPS) LP minima are not authorized.
