18
Q

when the master “LIGHTS TEST and DIM SWITCH” is placed in the test position what happens to the system

A

placing the master lights test and dim switch in the TEST position will result in a master caution recall and any stored fault will cause the associated light to remain illuminated when the switch is released

19
Q

when the EMER EXIT LIGHTS switch is in the ARMED position when will the emergency lights automatically illuminate

A
  • DC BUS no.1 power lost; OR
  • AC power is turned off
20
Q

what frequencies does the ELT (Emergency Locator Transmitter) transmit on

A

121.5/243/406MHz

21
Q

with the ELT in the armed position what triggers its transmission

A

when a preset G-load limit is reached

22
Q

what do the following lights mean on the flight deck access panel:
- green
- amber
- red

A
  • green = door unlocked
  • amber = correct emergency access code entered before door unlocked
  • red = door locked or flight deck access system switch - OFF
23
Q

what does the “LOCK FAIL” light indicate on the flight deck door lock panel

A
  • flight deck door lock in AUTO and door has unlocked or failed; OR
  • flight deck access system switch - OFF
24
Q

what does the “AUTO UNLK” light indicate on the flight deck door lock panel

A

correct emergency access code entered.
indication will flash and continuous chime until door unlocks

25
Q

what does an amber exterior door annunciation mean

A
  • related door is not closed and locked
26
Q

what does an amber overwing door annunciation mean

A
  • related door is not closed and locked
  • related flight lock failed to engage when commanded locked
27
Q

with the PASS OXY switch in the normal position when will the passenger drop downs mask automatically drop

A

14,000’ cabin altitude

28
Q

with the “fasten seat belts” switch in the AUTO position what controls the lights

A

ON = flaps OR gear extended
OFF = flaps AND gear retracted

29
Q

what controls are available to switch on the emergency exit lights

A
  • flight deck 3 position switch (OFF/ARM/ON)
  • aft attendant panel switch (overrides flight deck switch)
30
Q

what are the interior emergency lights made up of

A
  • lower inboard corner of stowage bins to illuminate the aisle
  • over the entry/svce and overwing emergency doors to indicate the door exits
  • ceiling to locate the exits and provide general illumination in exit areas.
  • self-illuminating exit sign FWD, MID, AFT cabin
  • photoluminescent strips which require charging)
31
Q

what are the exterior emergency lights made up of

A
  • illumination of the escape slides
  • fuselage lights illuminate the escape slides and overwing ground contact area
32
Q

cabin drop down masks:
- where are they located
- how many masks per location
- how are they dropped (auto/man)

A
  • PSUs, attendant stations, lavatories
  • 4 masks/ PSU, 2 masks/ attendant station + LAV
  • AUTO = CAB ALT > 14,000’
    MAN = passenger oxy switch - ON
33
Q

when is the pressure breathing automatically triggered for the FC oxy masks (EMER)

A

27,000’

34
Q

how long do the portable protective breathing equipment (PBE) units last

A

15 to 20 minutes

35
Q

how long do the passenger oxy masks last

A

12 minutes (22 minutes 900 and beyond)

36
Q

passenger portable oxygen cylinders:
- pressurised to?
- sizes
- flow rates (uses)

A
  • 1800psi
  • 120L/202L/311L
  • 2L/min = supplemental walk around oxy
    4L/min = first aid oxy
37
Q

what does the pressure regulation valve in the cargo compartments do

A

the pressure regulation valve at the aft bulkhead of each cargo compartment allows only enough air flow in or out of the cargo compartments to keep the pressures nearly the same as the cabin

38
Q

what do blowout panels in the cargo compartments do

A

provide pressure relief at a greater rate than the pressure equalisation valves in case the airplane pressurisation is lost

39
Q

what emergency exits are available on the aircraft

A
  • FWD/AFT ENTRY doors
  • FWD/AFT SVCE doors
  • OVERWING exits (2/4)
  • 2x flight deck windows
40
Q

how are the overwing emergency exits held in place

A
  • mechanical locks
  • cabin pressure
41
Q

when does the flight lock engage

A

the overwing emergency exits lock when:
- 3/4 ENTRY/SVCE doors are closed; AND
- either engine is running; AND
- airplane air/ground logic indicates that the airplane is in the air or both TL are advanced
the overwing emergency exits unlock when any one of the above conditions is not met OR DC power is lost

42
Q

what indications appear if flight lock has failed locked or a fault is detected

A
  • PSEU (Proximity Switch Electronic Unit) light illuminates
  • OVERHEAD annunciator
  • MC
    inhibited from takeoff until 30s after the airplane is in the ground mode
