How do the cabin seat belt signs work when operating in the AUTO position on the Seat Belt Selector?
Seat Belt Signs are turned off or on automatically with reference to:
Landing gear configuration (not up and locked) or
Flap position (lever not up and locked) or
Aircraft altitude (below 10300 ft 200A/B) or
Cabin altitude above 10000 or
Passenger oxygen on
Each emergency lighting system component has battery power that provides at least ______ minutes of operation if fully charged?
15
When does the nose landing light illuminate in the on position?
Only when the nose gear is down and locked
With the nose gear retracted does the Taxi light illuminate?
No. Only with gear down and locked
What switch positions allow emergency lights battery packs to be charged from DC power?
All switch positions. But lights on is insufficient to maintain the battery packs charge
When pilot oxygen masks are not in the container, closing the left door and then pushing down on the PUSH TO TEST AND RESET slide lever does what?
Shuts off oxygen to the mask and re-selects the boom mic.
The oxygen masks and chemical generators are located above the seats in passenger service units (PSUs). How are the masks deployed?
Automatically when cabin altitude exceeds approximately 13,500 ft or
Manually from the flight deck using the PASS OXYGEN switch on the panel
What does pilot oxygen EMERGENCY position supply?
100% oxygen under positive pressure at all cabin altitudes.
(200A/B/322) When the flight deck door is closed and electrical power is available, the door locks automatically. How is access granted
Using the emergency access code or depowering the airplane
(200A/B/322) Flight Deck Door emergency access can be denied by the pilots at any time within the first ____ seconds by momentarily selecting ____.
30, DENY
(200C) If the Flight Deck Door does not automatically unlock 30 seconds after pushing the emergency entrance switch, pilots should
Contact MX
Bleed air is supplied to _____
Aft and Bulk cargo heat Air conditioning Air driven hydraulic pumps APU and engine start Hydraulic reservoir pressurization Potable water system pressurization Pressurization TAT probe aspiration Wing and engine anti−ice
APU bleed air is used primarily during ___ for ____.
Ground operations, for air conditioning pack operation and engine starting
The engine bleed air valves are armed when the ENGINE bleed switches are selected ON.
For what reasons do the engine bleed valves close automatically?
During engine start When a ground cart is supplying air For bleed source loss (think engine shut down) When an engine fire switch is pulled For bleed air over−temperature For bleed air overpressure For a bleed air duct leak
Left, center, and right isolation valves divide the bleed air duct into segments. The center isolation valve is normally closed, except during _____.
during engine start or single engine bleed source operation
Engine bleed air comes from _____.
High stage or low stage engine compressor section.
When one pack enters standby cooling mode and the other is operating normally, the pack in standby may automatically shutdown at ____ and will restart when _____.
at lower altitudes or higher outside air temperatures
when ambient conditions permit standby cooling
Air from the lower recirculation fans is mixed with ____ before entering supply ducts. Air from the upper recirculation fans feeds directly into the ____.
pack air
supply ducts.
The target temperatures of each passenger cabin temperature zone can be modified ____ degrees F, within the range of ____F to ____F.
+/- 10
65
85
The FLIGHT DECK TEMP selector sets flight deck temperature between ____ degrees F and ____ degrees F.
65
85
The HIGH setting on the bulk cargo temperature selector turns on bulk ventilation fan, which provides for animal carriage. What does an overheat in the aft or bulk compartment cause?
Can heat be restored?
The system to shut down automatically and an EICAS advisory message CARGO HEAT (AFT/BULK).
Cargo heat to the affected compartment cannot be restored inflight.
The forward cargo compartment is heated by air from the ____
forward equipment ventilation system.
If the forward equipment cooling system is inoperative the EICAS advisory message EQUIP COOLING displays. How is the ground crew made aware of the condition?
The ground crew call horn in the wheel well sounds.
In flight smoke evacuation of the flight deck and equipment cooling of the lower forward
pressurized section is provided by the equipment cooling system override mode. Under what
conditions does this override mode operate automatically?
The EQUIP COOLING switch is OFF, or In flight, both supply fans fail, or In flight, low airflow is detected, or Smoke is detected in the forward equipment cooling system or the forward equipment ventilation system, or The FWD CARGO FIRE ARM switch is ARMED.
