16
Q

When will packs turn on with wings turned on

A

500’

17
Q

Concerns with single pack ops

A

Max alt. 31,000
Temp control is different
Make slight temp changes on operative zone with 10 minute delay between selections

18
Q

What hydraulic features assist an air start

A

FADEC unloads the EDP to help spool up

19
Q

Red circle on gear indication, is gear down and locked

A

Yes, but handle and position don’t match

20
Q

What is only surface powered by all 3 Hyd systems

A

Elevator

21
Q

What is 5 thing ac ess bus provides

A

Battery charging

22
Q

If you land in manual press mode, will plane depressurize on landing

A

No

23
Q

What is the min Hyd temp to run a PBIT and what do you do if the temp is lower than it

A

10°C

Perform a Hyd system warmup per the SOPM procedure

24
Q

What is the min Hyd temp for an engine start

A

-18°C

25
Q

You don’t have a Landing field elevation number on EICAS, what is a reason why

A

No closed flight plan on MCDU

26
Q

What does the Air management system use bleed air for

A

Environmental Control System (ECS);
Engine start;
Engine anti-ice and wing anti-ice;
Water pressurization.

27
Q

What is a consideration if you have put out an engine fire and are in icing conditions

A

You may want to stow the fire handle.
The wing xbleed will be commanded closed if the handle is pulled and you cannot provide heat to the wing on the inoperative engine side

28
Q

Can you use the APU to run the packs when taking off in icing conditions

A

No, the APU cannot provide for engine or wing anti-icing

29
Q

What is the only condition where the packs will be on during takeoff

A

With all anti ice selected off and the APU bleed avail

30
Q

When will the packs turn back on after takeoff

A

500’

31
Q

When will the recirc fans be commanded off

A

Both packs are commanded OFF;

– During on ground, cabin warm-up mode with the APU as bleed source according to a function of ambient temperature and altitude;

– The cargo bay fire signal activates;

– The DUMP button is pressed;

– Smoke is detected in the recirculation bay

32
Q

When will the RAM air open

A

The flight deck pack emergency ram air ventilation valve is commanded OPEN only if both ECS cooling packs are commanded OFF or failed OFF and the plane’s altitude is less than 25000 ft.

An emergency ram air ventilation check valve is provided and does not require electronic control. The emergency ram air check valve will be open whenever the pressure in the ram air circuit is greater than cabin pressure.

33
Q

When will Hyd 3b pump turn on automatically

A

When 3a fails

34
Q

How does the Hyd system help an engine air start

A

FADEC will depressurize the EDP to facilitate an easier air start

35
Q

What does the unloader valve do in Hyd sys 3

A

Used only in electrical emergency The pump unloader valve is used to reduce the discharge pressure of ACMP 3A during its start-up. This will reduce the pump torque and therefore reduce the electrical power required to start the pump.

36
Q

What does the flow limiter valve do in Hyd sys 3

A

Used only in electrical emergency
The flow limiter valve is used to reduce the amount of flow provided by the ACMP 3A. This will limit the electrical power that the pump can draw and prevent the electric hydraulic pump from stalling the RAT

37
Q

What is the purpose of the gear electrical override switch

A

When the landing gear lever control box fails the electrical override system is used to extend the landing gear.

The electrical override system bypasses the PSEM and commands gear extension in the same sequence as the normal operation.

38
Q

When can the landing gear aural warning not be inhibited

A

SLAT/FLAP lever in a landing position (5 or FULL) • Regardless of thrust lever position and radio altitude.

SLAT/FLAP lever in the 0, 1, 2, 3 or 4 position • Radio altitude below 700 ft AGL, and

  • Either thrust lever is set below 45° for two operative engines, or
  • Thrust lever is set below 59° for a one-engine inoperative condition.

Radio Altimeter Fail • In the event of dual radio altimeter failure, the warning inhibition button silences the aural warning only if the SLAT/FLAP lever is in the 0, 1, 2, 3 or 4 position.

39
Q

What are the main functions of the BCM

Brake control module

A
  • Locked wheel protection.
  • Antiskid protection.
  • Automatic wheel braking.
  • Touchdown protection.
40
Q

Below what speed does anti skid protection turn off

A

10 kts
