The term angle of attack is defined as
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
Which of the following refers to Bernoulli's principle
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
An aircraft said to be inherently stable will
Be difficult to stall
Require more control inputs to maintain altitude
Not spin
Require less control inputs to maintain altitude
Which of the following increases the load factor compared to straight and level
Climbing
Turning
Stalling
Descending
Electrical power is distributed to the various components via the
Fuses
Generator
Bus bar
Ammeter
In what flight condition must an aircraft be placed for a spin to occur?
Partially stalled with one wing low
A steep, low airspeed climb
A steep divind spiral
Stalled
What is one purpose of wing flaps?
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.
What must a pilot be aware of regarding ground effect?
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
When taking off or landing behind larger aircraft, pilot should be aware of wake turbulance
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
During the pre-flight the pitot heater (if fitted) should be checked
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

The operating principle of a float type carburettor is based on the
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
I an aircraft with a fixed pitched propeller and a carburettor, the first sign of carburettor ice
Is increasing oil temperature and cylinder head temperature
Is engine roughness
Is a loss in RPM
Is decreasing oil temperature and cylinder head temperature
Filling the tanks after the last flight of the day
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
If detonation is suspected during climb with a fixed pitch propeller the pilot should
Lean the mixture
Raise the nose to decrease speed
Lower the nose to increase speed
Apply carburettor heat
Best angle of climb speed is the speed that gives the
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
What is the main advantage of a constant speed propeller?
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
In which flight condition is the engine torque effect greatest for a single engine aircraft?
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
Which instruments become inoperative if the static port is blocked?
Air speed indicator
Altimeter
Altimeter and vertical speed indicator
Altimeter, airspeed indicator and vertical sped indicator
Which colour on the airspeed indicator shows the power-off, no flap stall airspeed?
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
What should be done if, during a turn, the balance ball is observed to be left of centre
Apply back pressure
Apply right rudder
Increase power
Apply left rudder
If the local QNH is not available before flight, what should be set on the altimeter?
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
To receive accurate indications from a direction indicator, it must be
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
The angular difference between true north and magnetic north is called
Magnetic deviation
Magnetic dip
Acceleration error
Magnetic variation
If the outside air temperature at a given altitude is warmer than standard, the density altitude is
Equal to the pressure altitude
Not effected by temperature
Lower than the pressure altitude
Higher than the pressure altitude
