Resource summary

Question 1

Question
The term angle of attack is defined as
Answer
  • The angle between the wing chord line and the relative airflow
  • The angle between the longitudinal axis and the horizon
  • The angle between the longitudinal axis and the wing chord line
  • The angle between the wing chord line and the horizon

Question 2

Question
Which of the following refers to Bernoulli's principle
Answer
  • For every action there is an equal and opposite reaction
  • An upwards force is generated as the lower surface of the wing deflects air downwards
  • Air travelling faster over the upper surface of an aerofoil creates a low pressure region above the upper surface
  • The the velocity of a fluid decreases, it's pressure decreases

Question 3

Question
An aircraft said to be inherently stable will
Answer
  • Be difficult to stall
  • Require more control inputs to maintain altitude
  • Not spin
  • Require less control inputs to maintain altitude

Question 4

Question
Which of the following increases the load factor compared to straight and level
Answer
  • Climbing
  • Turning
  • Stalling
  • Descending

Question 5

Question
Electrical power is distributed to the various components via the
Answer
  • Fuses
  • Generator
  • Bus bar
  • Ammeter

Question 6

Question
In what flight condition must an aircraft be placed for a spin to occur?
Answer
  • Partially stalled with one wing low
  • A steep, low airspeed climb
  • A steep divind spiral
  • Stalled

Question 7

Question
What is one purpose of wing flaps?
Answer
  • To enable steeper approaches to land without increasing speed
  • To relieve control pressure
  • To decrease wing area to vary lift
  • To decrease lift in order to descend.

Question 8

Question
What must a pilot be aware of regarding ground effect?
Answer
  • Wingtip vortices increasing creating wake turbulence for following aircraft
  • Induced drag decreases, any excess speed at the flare may cause excessive floating
  • A full stall landing will require less up elevator than a stall out of ground effect
  • Settling to the surface abruptly when landing

Question 9

Question
When taking off or landing behind larger aircraft, pilot should be aware of wake turbulance
Answer
  • Rising from a crossing runway into the take off or landing path
  • Rising into the circuit pattern
  • Rising into the flight path of aircraft above the aircraft generating wake
  • Sinking into the flight path of aircraft below the aircraft generating the wake

Question 10

Question
During the pre-flight the pitot heater (if fitted) should be checked
Answer
  • If flight into known icing is planned
  • Turning is on and letting it run
  • By turning it on briefly and feeling for it to start warming up, then turning it off
  • The pitot heater must not be turned on while on the ground

Question 11

Question
Given airfeild elevation 1000 feet, temperature 12 celsius and QNH 1024. calculate density altitdue
Answer
  • 463
  • 703
  • 583
  • 943

Question 12

Question
The operating principle of a float type carburettor is based on the
Answer
  • Automatic metering of air in the venturi as the aircraft climbs
  • Difference in air pressure between the venturi throat and the air inlet
  • Increasing air velocity at the throat causing increased air pressure
  • Decreasing air pressure at the throat causing increasing air pressure

Question 13

Question
I an aircraft with a fixed pitched propeller and a carburettor, the first sign of carburettor ice
Answer
  • Is increasing oil temperature and cylinder head temperature
  • Is engine roughness
  • Is a loss in RPM
  • Is decreasing oil temperature and cylinder head temperature

Question 14

Question
Filling the tanks after the last flight of the day
Answer
  • Forces any existing water to the top of the tank, away from the fuel lines
  • Prevents expansion of the fuel and subsequent evaporation
  • Makes it easier for the next pilot especially if they have passengers
  • Prevents moisture condensation by eliminating the airspace in the tanks

Question 15

Question
If detonation is suspected during climb with a fixed pitch propeller the pilot should
Answer
  • Lean the mixture
  • Raise the nose to decrease speed
  • Lower the nose to increase speed
  • Apply carburettor heat

Question 16

Question
Best angle of climb speed is the speed that gives the
Answer
  • Most altitude gained per unit distance covered
  • A compromise between climbing and distance travelled
  • Most altitude gained per unit time
  • The greatest angle of attack the aircraft can climb

Question 17

Question
What is the main advantage of a constant speed propeller?
Answer
  • It permits the pilot to select and maintain desired airspeed
  • It permits the pilot to select the blade angle for the most effective performance
  • It provides smoother operation with stable RPM
  • It is easier for student to learn

Question 18

Question
In which flight condition is the engine torque effect greatest for a single engine aircraft?
Answer
  • Low airspeed, high power, high angle of attack
  • Low airspeed, low power, low angle of attack
  • High airspeed, high power, high angle or attack
  • Straight and level flight at cruise speed

Question 19

Question
Which instruments become inoperative if the static port is blocked?
Answer
  • Air speed indicator
  • Altimeter
  • Altimeter and vertical speed indicator
  • Altimeter, airspeed indicator and vertical sped indicator

Question 20

Question
Which colour on the airspeed indicator shows the power-off, no flap stall airspeed?
Answer
  • The upper limit of the green arc
  • The lower limit of the green arc
  • The upper limit of the white arc
  • The lower limit of the yellow arc

Question 21

Question
What should be done if, during a turn, the balance ball is observed to be left of centre
Answer
  • Apply back pressure
  • Apply right rudder
  • Increase power
  • Apply left rudder

Question 22

Question
If the local QNH is not available before flight, what should be set on the altimeter?
Answer
  • The elevation of the nearest airfield, corrected to mean sea level
  • The elevation of the departure airfield
  • Pressure altitude corrected for non-standard temperature
  • Density altitude corrected for non-standard temperature

Question 23

Question
To receive accurate indications from a direction indicator, it must be
Answer
  • Regularly adjusted for changing QNH
  • Regularly checked against the local magnetic dip
  • Regularly aligned with the magnetic compass in level, unaccelerated flight
  • Regularly checked from gyroscope toppling

Question 24

Question
The angular difference between true north and magnetic north is called
Answer
  • Magnetic deviation
  • Magnetic dip
  • Acceleration error
  • Magnetic variation

Question 25

Question
If the outside air temperature at a given altitude is warmer than standard, the density altitude is
Answer
  • Equal to the pressure altitude
  • Not effected by temperature
  • Lower than the pressure altitude
  • Higher than the pressure altitude
