What are the takeoff and landing crosswind limitations?

A

OPERATIONS PROHIBITED

24
Q

Two hydraulic systems inoperative, pilot flying……

A

Be aware to fly 10 to 20 kts above minimum speeds and adjustment for Vref 30 plus 20-25 kts

25
Q

How many motors operate the Outflow Valves?

A

4 total - two electric motors per outflow valve, one AC and one DC.

26
Q

Which main display turns ON when STB PWR is selected to AUTO?

A

Left PFD
Left ND
Upper EICAS

27
Q

When EXT 1 or APU 1 PWR ON is selected, which bus is powered?

A

Synchronous bus is powered.

28
Q

On hydraulic System 4 what does the Aux pump pressurize?

A

It pressurizes the hydraulic brake accumulator.

29
Q

Why do the Leading Edge Flaps (LED’s) retract at Thrust Reverser application?

A

To prevent damage to the LEFs.

30
Q

What are speed brakes not recommended beyond flaps 20?

A

Airflow disruption effectiveness of flaps 25-30 may occur.

31
Q

Pulling the Engine Fire Switch shuts down which fuel valves?

A

Wing spar valve and engine shutoff valves.

32
Q

You fly 18 hours from point A to B. Now you need to fly to C. What MUST you do with the IRUs?

A

Completely Re-initialize / Align the IRUs

33
Q

On a military airport, how would you get position coordinates?

A

The coordinates can be retrieved from the computer flight plan (release) to be verified against the GPS present position coordinates.

34
Q

How does Depress/Discharge work for Main Deck Cargo Fire / Smoke?

A

9,000 ft/min to 20,000 ft

then

2,500 ft/min to 25,000 ft
This action creates vacuum in the system.

35
Q

When the Over Pressure Relief Valve opens, what happens?

A

Pack 2 shuts down to help relieve the excessive cabin pressure

36
Q

Why do we have 11 psi (slight negative pressure) for T/O and LDG?

A

A light weight flight attendant could open the doors

To help minimize pressure bumps during T/O.
