C) When electrical power is established
D) Only after both engines have been started
5) 757/767: According to the graphic, the R AOA light is illuminated. This indicates:
A) Angle of attack vane heater failure or only one engine running on ground
B) Angle of attack vane heater failure or neither engine running on ground
C) An air leak has been detected in the probe heater system
D) An overheat condition has been detected in the probe
6) 764: According to the graphic, the ICE DET light is illuminated, what does it indicate?
A) System anti-icing is no longer available
B) The ice detector system has failed
C) Icing conditions have been detected and an anti-ice valve is not open
D) Auto operation is still available but manual anti-ice/de-ice can no longer be selected
7) 764: According to the graphic, the ICING light and engine anti-ice VALVE light are illuminated. The aircraft is airborne. What is the status of the anti-ice system?
A) Auto operation is still available but manual anti-ice/de-ice can no longer be selected
B) System anti-icing is no longer available
C) The ice detector system has failed
D) An anti-ice valve is closed and engine/wing icing is detected
8) 757: The wing anti-ice system provides bleed air to:
A) The three outboard leading edge slats on each wing
B) Three leading edge slats immediately inboard of the engine on each wing
C) The three inboard leading edge slats on each wing
D) Three leading edge slats immediately outboard of the engine on each wing
9) 767: The wing anti-ice system provides bleed air to:
A) Three leading edge slats immediately outboard of the engine on each wing
B) The three outboard leading edge slats on each wing
C) Three leading edge slats immediately inboard of the engine on each wing
D) The three inboard leading edge slats on each wing
10) 757: Thermal anti-ice (TAI) pressure indicators are installed near the forward side of each engine directly aft of the intake. The TAI is normally flush, but extends outwards:
A) After first engine start
B) When the associated engine anti-ice switch is selected ON
C) If a leak is detected in the inlet cowl ducting
D) When the wing anti-ice switch is selected ON
11) 757/767: Maximum EPR/N1 limits are automatically reduced:
A) When the wing anti-ice valve is in the open position
B) When the wing anti-ice valve is in the closed position
C) When the VALVE light illuminates and the EICAS advisory message L or R WING ANTI-ICE displays
D) On the ground, when the wing anti-ice switch is selected ON
12) 757/767: Maximum EPR/N1 limits are automatically reduced:
A) When the associated engine anti-ice switch is selected off
B) When the VALVE light illuminates and the EICAS advisory message L or R ENG ANTI-ICE displays
C) When the associated engine bleed air valve is closed
D) When the associated engine anti-ice switch is selected on
13) 757/767: The thermal anti-ice (TAI) annunciation appears above the EICAS N1 indication when:
A) When a wing anti-ice valve is open
B) When an engine anti-ice valve is open
C) When a wing anti-ice valve disagrees with the switch position
D) When an engine anti-ice valve disagrees with the switch position
14) 764: The anti-ice (WAI) annunciation appears above the EICAS EGT indication when:
A) When a wing anti-ice valve is closed
B) When the wing anti-ice valve disagrees with the switch position
C) When a wing anti-ice valve is open
D) When a landing is made with the WING ANTI-ICE switch ON
15) 757/767: According to the graphic, the total air temperature (TAT) probe(s) light is illuminated. This indicates:
A) Total air temperature probe(s) heater failure or neither engine running on ground
B) Total air temperature probe(s) heater failure or only one engine running on ground
