01.How many outflow valves are there? Two, one electro-pneumatic and one pneumatic outflow valves. Two, electro-pneumatic outflow valves. Two. pneumatic outflow valves.
02. The pneumatic outflow valve: Is always slaved to the electro-pneumatic outflow valve. Operates in manual mode only. Is slaved to the electro-pneumatic outflow valve in automatic mode only.
03.In normal operation without failure the digital controller uses as reference: ADC 1 and captain altimeter Baro setting. ADC 2 and Captain altimeter Baro setting. ADC 1 and 1013 HPa. ADC 2 and 1013 HPa.
04. What are the correct indications during a pressurisation system test? The amber FAULT light in the MAN PB. The landing elevation indicator displays alternatively 18800 and -8800. A+B and the test is inhibited in flight.
05. If automatic pressurization control is desired, in which position should the MAN RATE KNOB be placed: NORM. AUTO. 9 o'clock position.
06. What do you set in AUTO PRESS PANEL before each flight? Departing airport field elevation, using QNH or zero if using QFE. Landing airport field pressure altitude. Landing airport field elevation, using QNH or zero if using QFE.
07. After take off the cabin altitude remains at take off elevation until the aircraft reaches 3500 FT ABOVE: Airfield elevation. Sea level. Theorical cabin altitude. Standard setting 1013 Hp.
08. The max cabin rate of climb, up to 20000 Ft in auto mode is: +550 ft/min. +400 ft/min. +500 ft/min.
09. What is the maximum cabin differential pressure? Positive 6.35 PSI, limited by a manometric capsule. Negative 0.5 PSI, limited by a non-return valve. A+B are correct.
10. What is the maximum cabin altitude (FL250 AP 6 PSI) ? 10000 FT. 6740 FT. 7640 FT.
11. How is the system protected against exceeding the maximum cabin differential pressure? Both outflow valves incorporate an electrically driven torque motor designed to fully open the valve. Both outflow valves incorporate a manometric capsule (aneroid) to hold the valve open sufficiently to prevent overpressure. Only the electro-pneumatic valve incorporates a manometric capsule to hold the valve open sufficiently to prevent overpressure.
In AUTO, what is the highest cabin rate of descent available with the descent rate push-button erased (norm)? -400 ft/min. -500 ft/min. -550 ft/min.
13. In AUTO, what is the highest cabin rate of descent available with the descent rate PB depressed (FAST)? -400 ft/min. -500 ft/min. -550 ft/min.
14. Before landing to avoid cabin pressure bump at touch down, the cabin altitude is automatically maintained at 300 ft bellow: Aircraft altitude. Theorical cabin altitude. Selected landing elevation.
15. After landing, the cabin depressurization rate is: +450 ft/min. +550 ft/min. +300 ft/min.
16. In case of ADC failure, the digital controller uses a reference aircraft static air pressure generated by: ADC 2 and CM 1 altimeter BARO setting. ADC 2 and CM2 altimeter BARO setting. ADC 2 and 1013 HPa.
17. What is the correct way to switch from automatic to manual operation? Select MAN on the CABIN PRESS PB, turn the MAN RATE KNOB to 9 o'clock position and operate the MAN RATE KNOB as required. Turn the MAN RATE KNOB to 9 o'clock position, select MAN on the CABIN PRESS PB and operate the MAN RATE KNOB as requiered. Select MAN the CABIN PRESS PB and operate the MAN RATE KNOB as required.
18. In MAN, what is the highest cabin rate of descent and climb available? -1500 ft/min +2500 ft/min. -2500 ft/min + 1500 ft/min. -550 ft/min + 1000 ft/min. -1000 ft/min. + 550 ft/min.
19. What is the correct way to switch from manual to automatic operation? Select to AUTO MODE the CABIN PRESS PB and turn the MAN RATE KNOB smoothly to normal position. Turn the MAN RATE KNOB to NORM position and select to AUTO MODE the cabin PRESS PB. It is not possible.
20. What happens in case of loss of electrical supply to the digital controller in automatic mode? Both outflow valves remain in the last position. Both outflow valves go to full open position. Both outflow valves go to full close.
21. In case of total DC electrical power lost? AUTO PRESS mode is lost. MANUAL PRESS MODE and CABIN PRESS IND are still available. A+B are correct.
22. The CCAS system is activated when the cabin altitude reaches: 6740 ft. 11000 ft. 10000 ft.
23. When is the DUMP function available? On ground only, MAN or AUTO PRESS mode. It only works in AUTO PRESS mode. It only works in AUTO PRESS mode, if differential pressure is below 1 PSI.
24. How many outflow valves are opened in DUMP function? Only the pneumatic valve. Only the electro-pneumatic valve. Both.
25. Selecting the DITCH MODE with the DITCH PB: Two electrical motors maintain both outflow valves in closed position, regardless of AUTO or MANUAL PRESS mode use. In addition to the white light on DITCH PB, MASTER CAUTION flashes amber and AIR amber light illuminates on CAP. A+B are correct.
