Year 3 general

Question 1

A/T LIM (white)

Answer 1

A/T Computer is calculating a single fixed N1 thrust limit for affected engine/s when FMC calculations become invalid or if either engine N1 is less than 18%.

Question 2

• • • • (on thrust mode display)

Answer 2

FMC not computing thrust limit.

Question 3

REVERSER (amber)

Answer 3

One or more:

• Isolation valve or thrust reverser control valve not in commanded position
• Thrust reverser sleeve position sensors are in disagreement.
• Auto restow circuit has been activated.

Question 4

LOW IDLE (amber)

Answer 4

• Thrust lever for either engine is near idle and the MEC on either engine is not commanded to maintain high idle RPM in flight.
• The speed of either engine is below 25% N1 in flight.

Question 5

What’s the difference between GPWS and EGPWS?

Answer 5

GPWS provides alerts based on radio altitude and combinations of baro altitude, airspeed, glideslope deviation, airplane config.
EGPWS uses these as well as an internal terrain database.

Question 6

In terms of predictive windshear, what does MONITOR RADAR DISPLAY tell you?

Answer 6

• Windshear within 3 miles and ahead of aircraft.
