Chapter 7 Flashcards
If starting an engine with a windmilling (from wind) propeller,
FADEC may not perform the check of the propeller independent overspeed protection circuit. If the check is not performed, the PROP 1 (2, 3, or 4) NO 119% PROTECT ACAWS Caution message will appear. Follow Crew Action for the ACAWS.
During engine start, pull the fire handle for…
For all ACAWS Warnings (red master warning light and tone), pull the FIRE handle and then place the ENGINE START switch to STOP.
During engine start, place the engine start switch to stop for…
For all other engine shutdowns on the ground, including normal shutdowns and shutdowns for ACAWS Cautions and Advisories, place the ENGINE START switch to STOP.
If any of the following Warnings occur, pull the engine FIRE handle and place the ENGINE START switch to STOP:
(1) ENG 1 (2, 3, or 4) FIRE.
(2) ENG 1 (2, 3, or 4) MGT HI.
(3) START VLV 1 (2, 3, or 4) OPEN.
(4) Visible indications of a fire.
(5) Visible fluid leak.
If any of the following conditions are observed, discontinue the start by placing the ENGINE START switch to STOP:
(1) No NG within 10 seconds after actuation of the ENGINE START switch to START.
(2) No indication of oil pressure within 15 seconds of NG rotation (ENG 1 (2, 3, or 4) NO OIL PRESS ACAWS Caution).
(3) No indication of oil pressure within 15 seconds of NP rotation (GEARBOX 1 (2, 3, or 4) NO OIL PRESS ACAWS Caution).
(4) ENG 1 (2, 3, or 4) FLAMEOUT ACAWS Caution, ENG 1 (2, 3, or 4) NO LIGHTOFF ACAWS Advisory and ENG 1 (2, 3, or 4) STAGNATED START ACAWS Advisory. (The FADEC automatically aborts the start for these, but still place the ENGINE START switch to STOP.)
Bleed Air consideration for high PAs
At pressure altitudes greater than 3,000 feet, reduce the bleed air requirement during takeoff by selecting the AIR COND CARGO COMPT POWER switch and UNDERFLOOR switch to OFF. This will reduce the possibility of an ENG 1 (2, 3, or 4) MGT HI (W) ACAWS event when takeoff power is applied.
Note regarding abrupt brake release
An abrupt release of deflected brake pedals could possibly cause the brakes on the left side of the aircraft to remain partially engaged, and could result in directional control difficulties during takeoff or landing roll. The pilot should smoothly release fully applied brake pedals over approximately 2 seconds.
