1. An aircraft design consideration that avoids a sudden drag rise approaching supersonic speeds, by ensuring there are minimal changes in cross-sectional area distribution from fore to aft, is called the: 

  1. area rule
  2. critical mach rule 
  3. four times rule
  4. Sears-Haack rule 

2. A sudden and significant form of drag produced when an aircraft approaches the critical mach number is termed: 

  1. wave drag
  2. form drag
  3. induced drag
  4. profile drag

3. Along a taxiway, the edge lighting is coloured: 

  1. green
  2. white
  3. white unless there is centreline lighting, and blue if there is not
  4. blue, and the centreline lighting is omnidirectional green

4. One US gallon of avgas is equivalent to approximately: 

  1. 4.5 litres and weighs about 3.2 kilos 
  2. 3.7 litres and weighs 2.7 kilos 
  3. 1.2 imp. gallons and weighs about 3.2 kilos 
  4. 0.75 imp. gallons and weighs about 7.5 kilos 

5. Carburettor icing: 

  1. is more likely at higher power settings 
  2. is most likely at ambient temperatures around -4 °C 
  3. can occur at ambient temperatures up to 38 °C
  4. will not occur at ambient temperatures above 20 °C

6. Dew point depression is the difference between:

  1. the wet and dry bulb temperatures, and fog is more likely as the difference increases
  2. ambient temperature and dew point, and fog is more likely as the difference increases
  3. the wet and dry bulb temperatures, and fog is more likely as the difference decreases 
  4. ambient temperature and dew point, and fog is more likely as the difference decreases

7. Relative humidity: 

  1. changes with temperature even if the amount of water vapour present does not change 
  2. changes with temperature only if the amount of water vapour present changes 
  3. does not change with temperature if the amount of water vapour present is constant 
  4. does not change with temperature if the dew point temperature does not change 

8. When moist air flows over a mountain and forms cloud, the cloud base on the lee side compared to that on the windward side is: 

  1. lower if precipitation has occurred 
  2. always lower due to orographic lift 
  3. always higher due to orographic lift 
  4. higher if moisture has been lost due to precipitation

9. The atmospheric temperature in an inversion: 

  1. decreases with height and the environmental lapse rate is said to be positive 
  2. decreases with height and the environmental lapse rate is said to be negative 
  3. increased with height and the environmental lapse rate is said to be positive 
  4. increases with height and the environmental lapse rate is said to be negative

10. In the presence of an inversion, the range of VHF communications may: 

  1. be reduced to less than line of sight due to an ionospheric reflection 
  2. be reduced to less than line of sight due to dialectric losses 
  3. be increased to greater than line of sight due to atmospheric ‘ducting’ 
  4. be increased to greater than line of sight due to ionospheric reflection 

11. The maximum speed for IFR and VFR aircraft in E or G airspace is:

  1. no restriction
  2. no restriction except 250 KT IAS in a CTAF or MBZ
  3. 250KT IAS below 10,000 AMSL
  4. 250KT IAS below F110

12. When there is high ground to the west of an airport, the official last light: 

  1. will be earlier 
  2. will be later 
  3. will not change but the actual onset of darkness will occur later 
  4. will not change but the actual onset of darkness will occur earlier 

13. The manoeuvring speed (VA) is typically marked on an airspeed indicator as: 

  1. a red line 
  2. the junction of the green and yellow arc 
  3. the high end of the white arc 
  4. is not usually marked 

14. The gyroscopic portion of a turn coordinator instrument responds to: 

  1. bank angle 
  2. bank angle and rate of yaw 
  3. rate of bank and rate of yaw 
  4. rate of yaw 

15. A VFR aircraft with an electrical system capable of powering a transponder may operate in E airspace provided that: 

  1. an airways clearance is first obtained 
  2. a flight plan is submitted and an airways clearance is obtained 
  3. a transponder operating in Mode C is carried and switched on and a listening watch is kept on the area frequency 
  4. a transponder operating in mode C is carried and a listening watch is kept on the MULTICOM frequency

16. On a piston-engine aircraft, the alternate air control: 

  1. is applicable to fuel-injected engines and is otherwise identical to carburettor heat 
  2. is applicable to all piston engines and is another term for carburettor heat 
  3. is applicable to fuel-injected engines and provides heated air to the injectors 
  4. provides an alternative, but not necessarily heated, induction air source in the event of air filter blockage

 

 

Answers:

  1. (a) The area rule is behind the ‘coke-bottle’ shape of some supersonic aircraft fuselages.
  2. (a) The rapid rise in wave drag at transonic speeds is behind the concept of the ‘sound barrier’. 
  3. (d) AIP AD 1.1 5.10.1
  4. (b) 
  5. (c) A carburettor icing probability chart is available from the CASA Online store.
  6. (d)
  7. (a) Relative humidity changes with temperature because the ability of the air to hold water vapour also changes with temperature. 
  8. (d) Moisture loss due to precipitation results in drier air and therefore, a higher condensation level, on the lee side. 
  9. (d) An increase of temperature with height is termed a negative lapse rate (Manual of Meteorology Part 1 para. 4.10). 
  10. (c) Ducting is said to occur when the transmitted wave is curved downwards because the upper portion of the wave encounters air with different refraction characteristics. 
  11. (c) AIP ENR 1.4 4.1
  12. (d) Additional time buffers should be considered in such locations because darkness occurs earlier. 
  13. (d) a is VNE (never exceed), b is VNO (normal operating), c is VFE (flaps extended)
  14. (c) The sensitivity to rate of roll is an aid to maintaining wings level but no indication of bank angle is given; d applies to the earlier simpler turn and slip indicator. 
  15. (c) 
  16. (d) An alternative induction air source is provided, usually unfiltered and from within the engine nacelle, in the event of blockage of the main source.
