Global - Ops & System Knowledge (ORAL) Flashcards
Which hydraulic pumps have priority in order? Name priority order of AC hydraulic pumps.
- 3A, 3B, 2B, 1B.
What does the color white mean when you select the flaps or slats?
- In transit.
What does yellow mean when you select slats or flaps?
- Inoperative or failure.
What does green mean when you select slats or flaps?
- Good. Flaps or slats are in the position pilot selected.
Why does pump 3A have an OFF switch and not an AUTO switch position?
- It’s a primary hydraulic pumps & operates continuously during normal ops.
Does the APU need one or two batteries to start?
- Needs both batteries to start APU. Rear APU BATTERY operates the starter. AVIONICS BATTERY is the brain with the FADEC.
At what point in the checklist do we retract the flaps and slats? In the air and on the ground?
- In the air: At FRA.Vfto-30 = Flaps 0. Vfto-10 = Slats In.
- On the ground: After exiting runway and performing After Landing flows.
Are SID and ODP departure procedures Single-Engine or Two-Engine?
- Two-Engine procedures.
Is Vac Two-Engine or Single-Engine performance?
- Vac is a Single-Engine performance based climb speed.
Will the RAT deploy on the ground?
- Yes.
What is climb gradient on departure based on?
- Two Engines operating.
How many Fuel Pumps does the Globals have?
- 10 total Fuel Pumps.
- Wing Tanks: 3 per tank (2 AC Primary Pumps and 1 DC Aux Pump)
- Center Tanks: 2 (AC Pumps).
- Aft Tanks: 2 (AC Pumps).
When do Fuel DC PUMPS operate?
- Operates when an AC pump fails, and…
- Slats/Flaps > 0°.
- In the air with gear down and locked.
- < 600 lb in each respective wing.
- Auto transfer stops.
Are Slats / Flaps electric or hydraulic?
- Electric.
What causes a secondary hydraulic pump (1B, 2B and 3B) to start if it is in AUTO?
If the secondary hydraulic pump is in AUTO and one of the following conditions occurs:
* Slats or Flaps are not IN / 0 degrees and at least 1 Engine Generator is operating.
* In flight when low pressure is detected, the associated B pump is automatically activated and will remain energized for a minimum of 5 minutes.
How do you know the climb gradient percentage by looking at a SID Chart?
- Under Ground Speed, reference the number at 100 kt. Next move the decimal over 2 spaces from the far right. (i.e., 417 = 4.17%).
Does ANTI-ICE come on in AUTO on takeoff?
- Not until 400 ft (ANTI-ICE can’t be in AUTO for takeoff…either on or off).
What are the APU Start Limitations?
- 3 start attempts in one hour.
- May start at or below 37,000 ft (bleeds can only be used up to 30,000 ft).
What are the Engine Start Limitations?
- 3 minutes ON, 15 seconds OFF.
- 3 minutes ON, 15 seconds OFF.
- 3 minutes ON, 15 minutes OFF.
What are the Fuel Panel Locations? Which Fuel Panel is “master” & which is the “slave”?
- Right Wing root and behind the LP’s seat.
- The 1st one turned on is the “master”.
- Wing Nav Lights: If secondary light is ON (smaller of two lights), does that mean a bulb is inoperative?
- Tail Nav Lights: If secondary tail-cone light is ON, does that mean that the primary light (T-Tail) inoperative?
- No, most likely overheated, could be failed.
- Yes. In this case you will be MEL’ing.
What turns ON Emergency Lights?
- Loss of DC Essential Bus.
How are the emergency lights powered?
By their own batteries (4).
How are the batteries charged?
- Each battery (Avionics & APU) has a dedicated AC powered battery charger.
How is the Engine operation managed?
- FADEC (L & R Engine and APU FADEC’s).
What hydraulic system does the RAT power?
- System 3.
What operates the nose wheel steering?
- Hydraulic powered and electrically controlled.
Can you steer with nose wheel steering off?
- Yes.
What is the crosswind limit when using the EVS HUD?
- 15 kt.
(EVS = Enhanced Vision System. Forward looking infrared used w/HUD).
What hydraulic system does the parking brake use?
- System 3.
If you set the parking brake and leave the plane can you trust that the brake will remain on?
- No.
What happens if you pull the emergency landing gear extension on the ground?
- Gear doors open.
What does the gear handle solenoid switch do?
- Prevents gear retraction on the ground.
- Allow gear retraction in the air if you can’t lift the gear handle up.
How many Pitot Covers? How many Gears Pins?
- 4 Pitot Covers.
- 6 Gear Pins (Left, Right, Nose Gear, Nose Door (maintenance), RAT, and Emergency Exit).
When does a Rotor Bow Start occur?
20 min to 5 hours after engine shutdown (FADEC is cooling a bowed N1 shaft due to uneven shaft cooling. Just spins until cools to temp, not a hot start).
