    Three full face quick-donning oxygen masks
  3. Where is the cockpit oxygen cylinder installed?
    The cockpit oxygen cylinder is located in an enclosure behind an access panel inside the forward left wardrobe closet aft of the cockpit wall.
  4. What occurs when the cockpit oxygen cylinder has less than 1410 psi?
    The readout changes to amber and an EICAS caution message "OXY LO PRESS" is displayed on the primary page.
  5. Where is the oxygen overboard discharge indicator located?
    It is installed flush with the outer skin on the lower left side of the fuselage, forward of the main passenger entry door and a few inches ahead of the static port.
  6. What is the location of the cockpit oxygen ground service panel?
    Ground Service Panel is on the right forward fuselage below the First Officer's side window
  7. What is the function of the yellow blinker located on the cockpit oxygen mask stowage box?
    It shows yellow when oxygen is flowing or when the harness is inflated. Black indicates no oxygen flow.
  8. What does the white oxygen on flag indicate?
    The oxygen shutoff valve is open.
  9. How is the oxygen flow shutoff valve closed after use?
    By closing the oxygen mask container doors and pressing the "press to test & reset" lever stops oxygen flow to the mask & removes the white on flag.
  10. What is the function of the Emergency Flow Control Knob located on the cockpit oxygen mask?
    To select a continuous flow of 100% oxygen to its mask
  11. What is the function of the NORMAL / 100% lever?
    • Normal: provides a mixture of ambient air with oxygen on demand.
    • 100%: provides 100% pure oxygen on demand.
  12. When will the cockpit oxygen masks supply 100% pure oxygen at a constant flow regardless of Normal/100% lever?
    With a cabin altitude of 30,000 feet or greater.
  13. How is the oxygen mask microphone activated?
    By selecting the MASK / BOOM switch to the MASK position on the associated audio control panel (ACP).
  14. What is the location of the cockpit oxygen cylinder service panel?
    The forward right side of the aircraft nose.
  15. What type of system provides oxygen to the passengers during a depressurization?
    Chemically generated oxygen system (oxygen generators).
  16. When will the passenger oxygen system automatically activate?
    When the cabin pressurization system detects a cabin altitude at or above 14,500 +/- 500 feet.
  17. How can the passenger oxygen system be manually deployed from the cockpit?
    By pressing the PASS OXY switchlight located on the cockpit overhead panel.
  18. What are the three ways the passenger service unit (PSU) oxygen mask container latch mechanism can be activated?
    • Automatically when the cabin altitude is at or above 14,500 +/- 500 feet
    • Manually via the pass oxy switchlight on the cockpit overhead panel or;
    • Physically by the flight attendant with either oxygen tools.
  19. How is a passenger oxygen system chemical generator activated?
    Pulling on the mask releases the firing pin and a chemical reaction produces and supplies gaseous oxygen.
  20. How long does chemical generator supply oxygen to its associated masks?
    Thirteen minutes.
  21. How many passenger oxygen masks are in each container on the Captain's side of the aircraft?
    Two
  22. How many passenger oxygen masks are in each container on the First Officer's side of the aircraft?
    Three
  23. How many oxygen masks are at each Flight Attendant station and in the lavatory?
    Two at each Flight Attendant station and two in the lavatory.
  24. How many portable oxygen cylinders are installed in the passenger cabin of the CRJ-700?
    Two
  25. What is the minimum dispatch pressure for the portable oxygen cylinders?
    1600 psi
  26. What is the location of the crew life vests on the CRJ-700?
    3 in the cockpit and one at each Flight Attendant seat
  27. When will the secondary navigation lights illuminate?
    The secondary navigation lights will activate automatically should the primary navigation lights fail.
  28. What is the difference between the primary and secondary wingtip navigation lights?
    The physical size and wattage of the secondary navigation lights is smaller than the primary lights.
  29. What occurs after selection of the rotating beacon switch to the on position?
    Two anti-collision beacons (one on the upper & lower fuselage) illuminate and the flight data recorder (FDR) is activated.
  30. What is the function of the ON position of the anti-collision strobe light switch?
    Three anti-collision strobe lights illuminate and the flight data recorder (FDR) is activated.
  31. What is the function of the RECOG / TAXI lights switch?
    It illuminates the left and right taxi/recognition lights.
  32. What is the function of the ON position of the LEFT LANDING light switch?
    It illuminates both the left wing landing light and left wing taxi/recognition light.
  33. What is the function of the on position of the RIGHT LANDING light switch?
    It illuminates both the right wing landing light and right wing taxi/recognition light.
  34. What are the locations of the cabin sterile lights?
    One cabin sterile light is located on the forward flight attendant control panel and the other is located on the aft flight attendant control panel.
  35. What is the function of the passenger service unit (PSU) reading light test switch light located on the forward attendant miscellaneous panel?
    Pushing the test switch supplies a ground to energize the test relay, which sets the PSU logic, causing all the reading lights to illuminate.
  36. What is the function of the AUTO position of the seat belt and no smoking sign switches?
    • No smoking auto position: signs illuminate with the gear down or cabin altitude greater than 10,000 feet.
    • Seat belts auto position: signs illuminate with the gear down or the flaps not at zero or cabin altitude greater than 10,000 feet.
  37. What is the function of the emergency lights battery packs?
    Four battery packs supply electrical power to the emergency lights if AC Essential and DC Essential power is lost and the Emergency Lights switch is set to ARM.
  38. How long will the battery packs provide power for the emergency lighting system?
    15 minutes
  39. What is the function of the ARM position of the emergency lights switch?
    It allows the battery packs to be charged by the aircraft electrical system and monitors for the loss of either essential DC or essential AC power which will cause the emergency lights to illuminate automatically.
  40. What is the function of the OFF position of the emergency lights switch?
    The emergency light system is disarmed and battery pack charging terminates.
  41. What is the total recording time of the Cockpit Voice Recorder (CVR)?
    120 minutes
  42. When does the Cockpit Voice Recorder (CVR) begin recording?
    Operation of the recorder system is continuous and starts automatically when the aircraft is powered.
  43. When does the Flight Data Recorder (FDR) start to record?
    Upon selecting the rotating beacon or anti-collision strobe light switches to the on position. The FDR will also automatically activate upon weight-off-wheels (strut extension after takeoff).
  44. What is the recording time of the Flight Data Recorder (FDR)?
    Twenty-five hours
