c. cabin differential will decrease

28. An aircraft climbs from sea level to 16 000 ft at 1000 ft per min, the cabin pressurization is set to climb at 500 ft per min to a cabin altitude of 8000 ft. The time taken for the cabin to reach 8000 ft is:

a. the same time as it takes the aircraft to reach 16 000 ft

29. The aircraft inhibiting switch connected to the A/C landing gear:

b. stops pressurizing on the ground and ensures that there is no significant pressure differential

30. Negative differential is limited by:

b. inward relief valve

31. To maintain a steady and constant airflow regardless of altitude or cabin pressure:

c. a mass flow controller is fitted

32. The term “pressurization cycle” means:

a. at higher than maximum differential

35. Ditching Cocks are operated:

b. to shut all outflow valves

36. Duct Relief Valves operate when:

a. excessive pressure builds up in the air conditioning system supply ducts

37. During a normal pressurized cruise, the discharge valve position is:

b. partially open

38. A dump valve:

b. is controlled manually

39. When air is pressurized the % of oxygen:

c. remains the same

40. If pressure is manually controlled:

d. care should be taken to ensure climb/descent rates are safe

41. An aircraft is prevented from pressurizing on the ground by:

b. inhibiting microswitches on the landing gear

42. If the pressurization air is passed over the cold air unit compressor it:

a. increases the charge air temperature

43. If the cabin pressure increases in level flight does the cabin VSI shows:

c. rate of descent

44. The term pressure cabin is used to describe:

b. the ability to pressurise the aircraft to a higher than ambient pressure

45. A pressurization system works by:
