With the right oil filter message displayed what is the first thing you will do?
Call for the QRH
What does a REV ISLN light on the ground indicate?
One thrust reverser may not deploy
When will the in-flight start envelope be displayed?
When an engine is shut down in flight and the secondary engine display is in view, and the associated ENG fire handle has not been pulled.
What malfunction has occurred if the right engine oil pressure light is on, the R ENG OIL PRESS message is displayed and the oil pressure indicates normal for the right engine?
Oil pressure switch fault

Moderate to severe turbulence
Volcanic ash
Icing conditions
Standing water or slush on runway
When is continuous ignition automatically selected on?
When engine A/I is on or LE flaps Extended
What colour does the EGT change to if the EGT limit is reached?
Red
What EEC normal mode protection is not available in EEC ALTN (or off) mode?
Overboost protection
How is the engine thrust reverser actuated on GE engines? PW engines?
767–300 GE: Pneumatically actuated by Fan air from respective engine
767–300 PW: Hydraulically actuated by respective HYD system

62,100
What is indicated when the start switch is in the AUTO position and VALVE light extinguished?
The start valve is closed, ignition off
Which rotor speed is indicated by N1?
Low pressure, fan section
What will occur if EGT exceed the red line limit?
Maximum exceedance value will be displayed and remain unless cleared by using the max indication reset button
How is fuel flow normally displayed?
Both Digital read out and pointer
What is the position of the Start valve with the start switch in GRD, and the VALVE light extinguished?
Open
What is the status of the engine ignition system with the fuel control switch in CUTOFF?
Off
What indicates that the start valve has opened and the air driven starter is turning the high-pressure compressor?
N2 Increasing
When that TMC computes a reference N1, where does the reference N1 appear?
Above the N1 digital counter
When must you have some indication of oil pressure during engine start?
Stabilised idle
What is the position of the reversers when the REV annunciations are not displayed?
Stowed and locked
Reverse thrust is supplied from?
The fan
What is the thrust reverser status if the Amber REV annunciation is displayed?
Unlocked or in transit
What colour is the REV annunciation when the thrust reverser is in transit?
Amber
When does the engine idle speed change to approach idle?
Approach idle is commanded whenever:
1. the engine anti Ice is on
2. CONT ignition is selected, or
3. When landing flaps are selected (25-30)
