Icing Conditions
Exist when Static Air Temp on the ground/takeoff or Total Air Temperature in flight is:
- 10°C or below; and
- Visible moisture is present, in any form, such as clouds, fog with visibility of one mile or less, rain, snow, sleet and ice crystals; or
- 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.
Engine and Wing Anti-Ice System Operations
CAUTION
On the ground, do not rely on visual icing evidence or ice detector actuation to turn on the engine anti-icing system. Use the temperature and visual moisture criteria specified in this section.
Delaying the use of the anti-icing system until ice build-up is visible from the flight Eco may result in ice ingestion and possible engine damage and/or flameout.
Minimum Fuel Tank Temperature:
-40°C
Max Fuel Imbalance Between Tanks
790 lbs
Max Altitude for Single PACK operation:
31,000 ft
Crossfeed Operations
The XFEED Selector must be set to OFF during takeoff and landing.
FLAPS
- Maximum Altitude with Flaps Extended: 20,000 ft
- Enroute use of flaps is prohibited
- Do not hold in icing conditions with Flaps extended
- The use of Flaps 4 during approach and landing is prohibited
Thrust Reversers
Must be stowed below 60 KIAS
RVSM
The ADS3 is not considered RVSM compliant in case of loss of sideslip compensation. (EICAS message ADS3 SLIPCOMP FAIL displayed)
FMS
FMS Speeds may only be used during normal flight operations.
Warm Up / Cool Down
- Before applying takeoff thrust, allow the engines to warm up for a min of two (2) minutes.
- A two (2) minute cool down must be observed prior to shutting down an engine.

Normal Operating Range
(FLEX) Use of reduced takeoff thrust procedures is not allowed:
On runways contaminated with standing water, slush, snow, or ice and
Are not allowed on wet runways unless suitable performance accountability is made for the increased stopping distance on the wet runway surface.
