Term
When will you see a VOR symbol on the MFD?
Definition
FMS Map or FMS Plan pages only w/HI/LO NAVAIDS selected on FMS MFD MENU page.
Term
How do you cancel a 'sink rate' GPWS warning?
Definition
Correct the aircraft condition to recover from the caution envelope. Note: Selecting GND PROX/TERRAIN switch to OFF does not inhibit GPWS modes 1-7 (sink rate is a mode 1 function).
Term
How do pax O2 generators work?
Definition
Chemical oxygen generators create O2 via a chemical reaction.
Term
How are the passenger O2 generators activated? How long will they last?
Definition
Activated by pulling on mask to release pin, lasts approx 13 min.
Term
When do you get the CABIN ALT caution message? CABIN ATL warning message?
Definition
CAUTION: Cabin Alt 8500'-10,000'.
WARNING: Cabin Alt > 10,000'.
Term
When will the O2 masks deploy?
Definition
CPAM deploys when cabin alt > 14,000', or manually by PASS OXY switchlight.
Term
How many PBE's are installed?
Definition
Three. 1 on the flight deck and 2 in the cabin (fore/aft).
Term
What is the minimum crew O2 dispatch pressure? To Canada?
Definition
1410/960 or Appendix A, 1650 Canada or lower approved by Mx.
Term
When does the OXY LO PRESS caution illuminate?
Definition
CREW oxygen bottle pressure < 1410/960 psi.
Term
What is the purpose of the SOP Appendix A O2 masks chart?
Definition
To determine if oxygen on-board is sufficient to dispatch when pressure is less than the standard minimum.
Term
On the pilot O2 mask, what is the function of the Normal/100% Emergency Flow Switch?
Definition
Normal: O2 mixed with ambient air, on demand.
100%: O2 only, on demand to 30,000', then continuous above.
Emergency Flow: 100% continuous.
Term
What does the OXY LO PRESS caution message indicates?
Definition
CREW oxygen bottle pressure < 1410/960 psi.
Term
When does the engine ATS normally cutout?
Definition
55% N2
Term
What is APR? How is it armed?
Definition
Automatic Performance Reserve. During takeof/climb, if either N1 drops below 67.6%, APR system automatically increases N1 approx 2% on the good engine for 5 minutes. APR switches to ARM, ENG Speed switches ON, WOW, N1 both engines >79%.
Term
Do you have APR on the Go-Around?
Definition
No, APR is not triggered due to arming logic (no WOW). However, the GA thrust settings are roughly 2% N1 higher than the TO thrust settings.
700/900: APR is available on the GA.
Term
How is the APR activated?
Definition
Once armed, during takeoff/climb, if either N1 drops below 67.6%, the other N1 is automatically increased approx 2%.
Term
You gain an additional ____ % or ____ lbs. of thrust with APR?
Definition
2% or 500 lbs.
Term
What do the engine speed switches do?
Definition
ON: Arms FCU to respond to thrust lever input using N1 "electronic fan speed" mode for power settings >79%, or N2 "hydro-mechanical" mode for lower power settings.
OFF: N2 mode only.
Term
What would happen if the right engine speed switch was selected OFF during climb out?
Definition
Rapid increase of N2 due to N1/N2 thrust lever position difference (N2 is greater for same position), which may result in exceedance of RPM and ITT limitations.
Term
When do you need continuous ignition?
Definition
1. Takeoffs and Landings on contaminated runways.
2. Takeoffs with high crosswind components >10 knots. (CRJ 200 only)
3. Flight through moderate or heavier intensity rain.
4. Flight through moderate or heavier intensity turbulence.
5. Flight in the vicinity of thunderstorms.
Term
When will continuous ignition be automatically activated?
Definition
High AoA, approaching stall.
Term
When does the thrust lever auto-retard?
Definition
When the reverser inadvertently deploys in flight.
Term
What does the UNLK light mean on the Thrust Reverse panel?
Definition
Thrust reverser is unlocked.
Term
What does L or R REV UNSAFE caution message mean?
Definition
Reverser is unsafe to arm in flight.
Term
Normal N1 thrust is displayed on ED1 in what color? Flex thrust?
Definition
Thrust reverser is unsafe to arm in-flight, Thrust reverser deploy switches have failed in a commanded deploy state but thrust reversers are not locked and are not armed.
Term
When do we check engine oil? How much oil can be added?
Definition
3 min to 2 hrs after shutdown, 2 quarts w/o dry motoring.
Term
If needed, when can you add engine oil?
Definition
15 min to 2 hrs after shutdown.
Term
When do you have to dry motor an engine after adding oil?
Definition
f the system has to be replenished to maximum capacity and the replenishment period has been exceeded, the engine(s) must be dry motored.
Term
When taxiing onto the runway, you receive a ____ caution message. What is the appropriate response in regards to maintenance action per the current FOM procedure?
Definition
