REV in amber or green
50
When is use of the thrust reversers prohibited?
During normal taxi and for power back
51
When do you need to select Anti Ice to Engine? When are the bleeds providing Anti Ice to the engines?
When the outside air temperature is between 5-10ºC and visible moisture up to 1700 AFE, or when operating on ramps, taxiways or runways with surface snow, ice, standing water, or slush that may be ingested by or freeze on the engines, nacelles or sensor probes.
Anti Ice is provided on engine start.
52
When do you need to select Anti Ice to ALL? When are the bleeds providing Anti Ice to the engines and the wings?
Anti Ice needs to be set to all when the OAT is less that 5ºC and visible moisture up to 1700 AFE, or when operating on ramps, taxiways or runways where surface snow, ice ,standing water or slush may be ingested by or freeze on the engines or probes.
Engine anti ice turns on with engine start; the engine bleeds are commanded open and heat the 3 outboard leading edges of the wings when wheel speed is above 40 kts.
