Q

What is the difference between MAX and TOGA?

A

MAX provides TO/GA reserve with ATTCS on, TOGA for normal ops.

Usually if you go MAX thrust manually it gives you GA RSV
Usually if ATTC does it automatically it gives you T/O RSV

Q

How many ways can you lower the landing gear?

A
  1. Normal
  2. Override
  3. EMER extension
17
Q

What does electrical gear override do?

A

Overrides dear down regardless of position normal selector is in.

18
Q

What does the Alternate Gear Extension lever do?

A

releases his Raul if pressure in the system, free falling the gear.

19
Q

Systematically, what happens when the landing gear lever is selected up or down?

A

Commands extension/ retraction of landing gear, requiring pressure in Hydraulic 2

20
Q

How does aircraft know to give a green down indication on the EICAS (what component verifies the signal)?

A

2 up and down lock sensors

21
Q

What causes a landing gear Lever Disagree msg.? How is it fixed?

A

Landing gear lever does not agree with at least one of the gear positions.

22
Q

What criteria must be met for the auto brakes to be armed to low, med or HI?

A
  1. Knob selected
  2. WOW indicates in flight
  3. Wheel speed below 60kt
  4. No faults
  5. Brakes not pressed,
  6. Any thrust lever position
23
Q

What can be done to disarm the auto-brake from low, med, or high?

A
  1. 20% pressure on toe brakes
  2. Thrust levers above idle
  3. Faults detected
24
