simple fault in the air/ground sensing system:

panel is released the GPS light extinguishes.
c) The GPS light illuminates when the annunciator panel is pressed. When the panel is
released the GPS light remains illuminated.
d) Only when a dual GPS receiver failure occurs, the GPS light will illuminate.

released the GPS light remains illuminated.
The Landing Gear Configuration Warning .
a) Can always be silenced with the warning HORN CUTOUT switch.
b) Can only be silenced with the warning HORN CUTOUT switch, above 200 feet, when
the flaps are UP through 10.
c) Can only be silenced with the warning HORN CUTOUT switch, above 200 feet, when
the flaps are UP through 15.
d) Can only be silenced with the warning HORN CUTOUT switch, above 400 feet, when
the flaps are UP through 15.
b) Can only be silenced with the warning HORN CUTOUT switch, above 200 feet, when
the flaps are UP through 10.
Statements: 1) Altitude alerting is inhibited when the trailing edge flaps are extended to 25 or greater. 2) At 200 feet from the selected altitude, the ALT ALERT annunciation does not longer show. a) Only statement 1 is correct. b) Only statement 2 is correct. c) Both statements are correct. d) No statement is correct.
a) Only statement 1 is correct.
Which statement about the Proximity Switch Electronic Unit light on the aft
overhead panel is not correct?
a) It is illuminated on the ground when a fault is detected in the PSEU.
b) It is illuminated on the ground when an overwing exit flight lock fails to disengage
when commanded.
c) On ground the light is illuminated when a ‘simple’ fault occurs.
d) In flight the light is inhibited for 30 seconds after landing.
c) On ground the light is illuminated when a ‘simple’ fault occurs.
Statements: 1) The Mach/airspeed warning systems can only be tested on the ground. 2) On the PFD amber bands indicate the minimum and maximum manoeuvring speed. a) Only statement 1 is correct. b) Only statement 2 is correct. c) Both statements are correct. d) No statement is correct.
c) Both statements are correct.
The GPWS provides alerts based on
a) Radio altitude and combinations of barometric altitude, AOA, airspeed & glideslope
deviation.
b) Radio altitude and combinations of airspeed, AOA, airplane configuration &
barometric altitude.
c) Radio altitude and combinations of airplane configuration, AOA, glideslope deviation
& airspeed.
d) Radio altitude and combinations of glideslope deviation, airplane configuration,
barometric altitude & airspeed.
d) Radio altitude and combinations of glideslope deviation, airplane configuration,
barometric altitude & airspeed.
The Look-Ahead Terrain Alerting GPWS
a) Database only contains terrain data near major airports.
b) Terrain data can be used as an independent database.
c) Will show terrain within 2000 feet of the airplane barometric altitude.
d) Will automatically be switched on when the airplane passes through the transition
level.
c) Will show terrain within 2000 feet of the airplane barometric altitude.
The red landing gear indication lights are illuminated under the following
conditions:
a) Landing gear is in disagreement with LANDING GEAR LEVER position.
b) Landing gear is not down and locked (with either or both forward thrust levers
retarded to IDLE, and below 800 ft AGL).
c) Landing gear is UP and locked, with the LANDING GEAR LEVER UP or OFF.
d) Both A and B are correct.
d) Both A and B are correct.
While performing the LANDING checklist, the PSEU light illuminates on RECALL.
This indicates:
a) A normal condition.
b) A fault is detected in the landing gear locking system or the air/ground sensing
system.
c) The landing gear configuration warning horn will sound upon landing.
d) A problem exists in the PSEU light, because this light should be inhibited in flight.
d) A problem exists in the PSEU light, because this light should be inhibited in flight.
.The stall management yaw damper (SMYD) computers determine when the stall
warning is required based on which of the following?
a) Anti-ice controls.
b) ADIRU outputs.
c) FMC outputs.
d) All of the above.
d) All of the above.
How can an Airspeed/Mach warning be silenced in flight?
a) Reduce the airplane speed to below Vmo/Mmo.
b) Press the Airspeed/Mach warning test switch.
c) Reduce the airplane speed to minimum manoeuvring speed.
d) Press the Airspeed/Mach override switch.
a) Reduce the airplane speed to below Vmo/Mmo.
When flying an ILS approach, to inhibit a BELOW G/S alert:
a) The BELOW G/S alert cannot be inhibited
b) Move the BELOW G/S switch to the Alert Inhibit position.
c) Push the BELOW G/S light (so that the alert will be inhibited below 1000 ft RA)
d) All of the above.
c) Push the BELOW G/S light (so that the alert will be inhibited below 1000 ft RA)
GPWS test can be performed:
a) Only on the ground.
b) From lift-off to 1000 ft RA.
c) Momentarily on the ground, or above 1000 ft RA in flight.
d) Anytime.
a) Only on the ground.
