Where is the flight crew oxygen bottle located on the 757?
Forward cargo compartment
Explain the three different flow selections on a crew oxygen mask.
EMER: 100% oxygen under positive pressure
100%: 100% oxygen on demand
NORM: air/oxygen mixture on demand (air/oxygen ratio depends on cabin altitude)

1,000 PSI
Why is one crewmember required to hold the test/reset switch on the oxygen mask for 10 seconds while monitoring the OXY PRESS readout on EICAS?
A decrease in 100 PSI over a 10 second period would indicate that the crew oxygen shutoff valve is closed.

Normally located in an overhead bin adjacent to the door
True or False: Emergency Locator Transmitters (ELTs) are installed in the passenger compartment and the flight deck.
True
What color are crew life vests? Passenger life vests?
Crew vests are orange, passenger vests are yellow
A passenger’s lithium ion battery in their laptop overheats and catches fire, which extinguisher is more effective: halon or water?
Water. (Halon extinguishers are very effective in fighting most fires, with the exception of combustible metals and metal alloy fires)
What two types of medical kits are available in the aircraft cabin?
- ) Enhanced Emergency Medical Kit (EEMK) usually with a medical accessory pouch nearby
- ) First aid kits
How many passenger entry doors are on most 767-300s?
4 (four)
Where is the inflatable life raft located in the 767-300?
A raft with a capacity for 46 people is located in the middle of the aircraft in a wall mounted compartment
What causes the EMER LIGHTS to automatically illuminate all emergency lights if the switch is in the ARMED position?
If the aircraft’s normal electrical power fails or is turned off
True or False: the EMERGENCY LIGHTS can be activated from the flight attendant panel regardless of the flight deck switch position.
True
How many emergency exits are on the 757-300?
14 (fourteen)
2 cockpit sliding windows, 6 entry doors, 4 overwing exits, and 2 emergency doors
What two instances would cause illumination of the amber UNARMED indicator next to the EMER LIGHTS switch on the overhead panel?
- ) The EMER LIGHTS system has been manually activated in the flight deck (i.e. switch in the ON position)
- ) The EMER LIGHTS switch has been selected OFF in the flight deck
The pneumatics system supplies bleed air to which four systems/purposes?
- ) Air conditioning and pressurization
- ) Wing and engine anti-ice
- ) Engine starting
- ) Hydraulic reservoir head pressure
True or False: the ISOLATION valve on the BLEED AIR panel must always be manually selected to open or close.
True, it has no automatic function
How is bleed air supplied from the engines?
By a low pressure (LP) port and a high pressure (HP) port in the compressor section of the engine
Which bleed air port, LP or HP, is used under most conditions? When is the other used?
Low pressure (LP) bleed air is used under most conditions. However, in some situations, like low power settings, LP bleed air may be insufficient. In this situation, the HP valve opens automatically.
Is there any indication in the flight deck as to which engine compressor bleed air port (LP/HP) is in use?
No.
What would an amber L ENG HI STAGE advisory message on EICAS, along with the HI STAGE light illuminated on the BLEED AIR panel indicate?
That the HP port was in use and it over-pressed. In this situation, the HP bleed air valve automatically locks in the closed position.
How are bleed air valves controlled? (electrically, mechanically, hydraulically, etc.)
They are electrically controlled (i.e. electronic switch in the flight deck), and pneumatically operated (i.e. air pressure physically moves the valve)
What does a L or R ENG amber OFF light on the BLEED AIR panel indicate?
- ) That the corresponding engine bleed air valve has closed automatically due to a system fault.
- ) The switch is OFF.
- ) The engine is not running.
What would an amber L ENG BLEED VAL advisory message on EICAS, along with an amber BLEED light illuminated on the BLEED AIR panel indicate?
A bleed air malfunction has occurred. (e.g. bleed air temperature became excessive)
Can the APU be used to supply bleed air for engine or wing anti-ice operations?
No, it does not provide sufficient bleed air for those purposes.
High pressure external air can be used for what two purposes?
- ) Engine starts (two external bleed carts are required, or one cart with two separate hoses)
- ) Air conditioning pack operation
How are bleed air leaks detected?
Temperature sensors mounted near ducts and manifolds.
What mechanism/power supply controls the outflow valve to maintain the desired cabin pressure?
2 AC powered motors, each a component of their respective automatic pressure controllers, actuate the outflow valve. In the event of a dual auto pressure controller failure, a DC powered motor provides manual control of the outflow valve.
The index mark on the AUTO RATE switch located on the CABIN ALTITUDE CONTROL panel represents what cabin altitude rate of change?
500 FPM Climb
300 FPM Descent
At what cabin altitude will the red CABIN ALTITUDE light on the CABIN ALTITUDE CONTROL panel illuminate, as well as the red CABIN ALT light on the forward discrete panel?
When the cabin altitude exceeds 10,000 feet. Both annunciators will extinguish when the cabin altitude descends below 8,500 feet.
Where are the five negative pressure relief vent doors located on the 767-300?
Two on each cargo door (right side), and another located immediately forward of the positive pressure relief valves (forward left side of fuselage)
Where are the positive pressure relief valves located on the 767-300?
Forward left fuselage.
Where are the two negative pressure relief vent doors located on the 757?
Forward right fuselage.
Where is the outflow valve located?
Aft left fuselage.
Where are the two positive pressure relief valves located on the 757?
Aft left fuselage.
What three pneumatic sources can provide enough air to operate the packs?
Bleed air from the engines or APU, and high pressure air from a ground source.
What is the purpose of recirculation (RECIRC) fans?
To maintain overall cabin air circulation while allowing a reduction of cabin air ventilation, effectively reducing PACK workload. This reduced flow reduces bleed air demand from the engines, reducing fuel burn.
Conditioned air for the flight deck is also used in which 2 compartments? and for what purpose?
Forward and aft E/E compartments, equipment cooling.
