  1. 1how many sets of boots does the AC have6
  2. 2how many deice boots are there on the wings12
  3. 3how many engine intake boots are there2
  4. 4how many vertical stabiliser boots are there2
  5. 5how many horizontal stabiliser boots are there4
  6. 6what is the normal position of the isolation valve in the bleed systmemopen
  7. 7what is the system pressure of the deicing system18 +/- 3 psi
  8. 8when does a light indication come on15 psi
  9. 9how many distribution valves are there6
  10. 10how many pressure transducers are there2 on each side
  11. 11during auto operation how long does each set of boots activate for6 seconds
  12. 12in slow mode what is the dwell period144 seconds
  13. 13in fast mode what is the dwell period24 seconds
  14. 14when in manual how is operation controlledselect each set of boots for 6 seconds,and have a dwell period of 24 seconds
  15. 15what does the gauge showthe pressure in the L and R systems
  16. 16in normal operation what does the gauges showthe same for the l and r systems
  17. 17how can the L and R boot air systems be isolatedby the boot air switch
  18. 18why would you want to split the L and R systemshelps identify faults and retains the pressure in the unaffected side
  19. 19what does the splitting of the systems allow forallows tail and intake boots to be operated in the event of a system leak
  20. 20what is the only direction that manual should be operated inanticlockwise
  21. 21how are the valves heated in manual modeall at the same time
  22. 22how do ice detection probes workice on probes alters frequency
  23. 23what will happen if ice is detected and the REF SWITCH is not selected to INCRICE DETECTED message will flash orange on the ED
  24. 24how long is the ice detected message illuminated for5 seoncds
  25. 25what is the indication if the ref speed switch has been selected to INCRwhite on black background REF speeds
  26. 26what happens if you get a dual ice protection system faultit will activate a CWP caution
  27. 27what happens if a single ice protection system fails?it is recorded in the Central diagnostic System
  28. 28what does the ice protection spigot indicatethe ice that is accumulating on the tail
  29. 29how much of the prop is deiced70%
  30. 30when is AC power onprop RPM above 400
  31. 31what power does the system need for prop deicingAC
  32. 32describe how the prop deicing test is doneNp (Condition Levers above minimum)
    Prop switch held at TEST
    Each light on for 7 seconds
    Wait 30 seconds before repeating, should you need to
  33. 33what is the limitation for the min temp required to ensure air inlet ice protection in flight65 degrees C
  34. 34what is the limitation for the min oil temp required for entering in flight icing condition and within what time period should it reach the higher temperature55 degrees C
    but must reach 65 within 3 mins of setting takeoff power
  35. 35what does selecting prop heat on doresets the low oil temp amber arc from 0 to 55
    the gauge changes
  36. 36what are the two positions on the Ref speed switch buttonINCR and OFF
  37. 37what does the REF speed switch doincreases the stick shaker activation datum by 20 kts
  38. 38how can you know if the REF SPEED button is on INCRby looking at the ED and seeing the message
    INCR REF SPEED in WHITE
  39. 39what warning will you get that you need to put the switch to INCRice detected message in AMBER
  40. 40what speeds are the 20 kts added toVMIN and the stick shaker
  41. 41what is added to VREFan increment dependant on flap setting
  42. 42what do you have to leave open when leaving icing conditions that wouldn't be on if you didn't enter icing conditions in the first placethe engine intake door
  43. 43what is the definition of icing in the airSAT 5°C or LESS
    and visible moisture
  44. 44what does the ground levers advancing on the ground dopre pressurise the ac
  45. 45what positions can the ENGINE INTAKE SWITCHLIGHT be inOPN
    CLSED
    HEATER
  46. 46what does the heater light indicatethat the engine intake heater is active
  47. 47what does pressing the ENGINE INTAKE SWITCH LIGHT doopens the doors and arms the heaters
  48. 48What conditions are needed for the heaters to activateOAT 15°C or below
    AND
    oil pressure above 44 psi
  49. 49how many pitot static probes are on the FOs side2
  50. 50what are #1 and #2 pitot static probes heated byrelative AC Busses
  51. 51when do the AoA heaters operatewhen the 115 V AC buses energise
