What are the prerequisites for the Automatic Descent Mode (ADM)?
• Cabin Altitude at or above 10,000 ft.
• Aircraft altitude at or above FL 340
• Autopilot engaged.
How long can we fly with the Standby Battery?
60 Minutes if one of the SMCs is depowered.
What happens when a fire handle is pulled?
Pulling the fire handle sends a fire shutdown signal to the FADEC, closes the Engine Hydraulic Shutoff Valve, closes the Engine Fuel Shutoff Valve.
The tiller will turn the nose wheel how many degrees?
+/- 60 degrees left and right of center.
What is the PMA and what is its function?
The PMA (Permanent Magnet Alternator) is mounted on the accessory gear box. It provides power to the FADEC when N2 is greater than 45%.
What hydraulic system operates the flaps?
LEFT
What spoiler will still operate with a loss of the left hydraulic system fluid?
- Inboard Spoilers (Multifunction Spoilers - MFS)
Which hydraulic system operates the ailerons?
None.
Ailerons are manually actuated (conventional mechanical)
What control surfaces are locked with the gust lock engaged?
Ailerons while on the ground.
In addition to locking the aileron surfaces, the locking mechanism prevents activating the engine thrust levers to prevent takeoff with locked aileron surfaces.
If the stall warning (stick shaker) activates, what will be disengaged and what will be enabled?
- Autopilot and autothrottles will be disengaged
- Auto-ignition and stick shakers will be enabled
When will the taxi lights turn off automatically?
Landing gear retraction
During a climb, at what altitude will the landing lights automatically turn off?
18,000 ft
Which hydraulic system components are powered by both the left and right system?
Elevator
Rudder
Park Brake
What modes will automatically engage the autothrottles?
Automatic Descent Mode
What cabin altitude will cause the passenger oxygen masks to deploy?
Cabin altitude of greater than 13,500 ft if landing field elevation is equal to or lesser than 8000 ft; or 14,750 ft if landing field elevation is greater than 8000 ft.
What happens when the AFCS DISCON bar on the FCP is pulled?
It disconnects the Auto Pilot, yaw damper and auto throttles. It also removes power from the elevator and aileron servos which disables the stick pusher.
What is the primary purpose of the APR mode?
To provide additional thrust on the operating engine during a single engine failure.
What are the four subsystems of the Pneumatic System?
• Wing Anti-Ice (WAI) System
• Environmental Control System (ECS)
• Temperature Control System (TCS)
• Bleed Air System (BAS).
What is the AMSC responsible for?
The AMSC (Air Management System
Controller) is responsible for Bleed Air
Management.
Basic functions include:
1. Engine port selection;
2. Regulation of pressure, temperature, and flow delivered to the pneumatic manifolds;
3. Bleed air cooling utilizing engine fan air, Wing Anti-ice, and Isolation between the left bleed air source and the right bleed air source.
