1The total drag on an aircraft is at a minimum
- AAt the normal cruise speed
- BJust below normal cruise
- CJust above the stall speed
- DAt Vne
2A spin is the result of
- AA stall
- BA turn
- CA yaw
- DA stall with yaw present, resulting in an angle of attack difference between the wings
3Frost on the wings will have the greatest affect by
- AIncreasing weight
- BChanging the shape of the aerofoil
- CCausing an early breakaway of the streamline flow
- DAll of the above
4The angle between the wing chord and the relative airflow is the
- AAngle of incedence
- Bflight angle
- CAngle of attack
- DRiggers angle
5The 406MHz ELT provides
- AA reduced accuracy in locating the beacon, reducing search areas
- BA greater accuracy in locating the beacon, reducing search areas
- CA louder and thus more noticeable distress signal
- DDirect link of position information to a computer at the aircraft's base
6Flaps are used on approach to land to
- ALower the nose, reduce the rate of descent and reduce the descent angle
- BRaise the nose, increase the rate of descent and reduce the descent angle
- CLower the nose, increase the rate of descent and increase the descent angle
- DSlow the aircraft down
7During a steep turn, more lift is required therefore
- AA reduced angle of attack is required
- BThe stalling angle increases
- CAn increased angle of attack is required
- DThe pilot must push forwards to prevent a stall
8In a steady climb, which of the following is correct
- ALift=Weight
- BLift is less then weight
- CThrust = Drag
- DDrag is greater than thrust
9If the pitot tube blocks instantaneously, what happens to the airspeed indicator
- AThe indication remains constant at the value it was showing when blocked
- BThe indication slowly decreases to zero
- CThe indication slowly increases to the maximum
- DThe airspeed indicator functions normally
10For any aircraft
- AThe stall airspeed remains constant and the stalling angle of attack varies
- BThe stall airspeed and the stalling angle of attack remain constant
- CThe stall airspeed and the stalling angle of attack both vary
- DThe stall airspeed varies and the stalling angle of attack remains contant
11The angle of attack on an aerofoil is the angle between?
- AThe fuselage and the aerofoil
- BThe aerofoil chord line and the relative airflow
- CThe bottom of the aerofoil and the relative airflow
- DThe aerofoil chord line and the horizontal stabilizer chord line
12Mass balancing of control surfaces is to
- AAssist the pilot in moving them
- BTo prevent the controls becoming too heavy at high airspeed
- CTo prevent flutter
- DThe ensure they don't return to neutral unless the pilot makes them do so
13The never exceed speed (Vne) is the maximum
- ASpeed at which aerobatics is permitted
- BSpeed at which full control deflection is permitted
- CSpeed permitted in smooth air
- DSpeed permitted in turbulent air
14To maintain altitude in level flight lift must remain constant. For this to occur
- AAngle of attack must increase if airspeed dereases
- BAngle of attack must increase if airspeed increases
- CAngle of attack must decrease if airspeed decreases
- DAngle of attack should be maintained if airspeed increases
15If an aircraft's indicated stall speed is 45 knots at 3000 feet, what is the stall speed at 6000 feet?
- ALower than 45 knots
- B45 knots
- CHigher than 45 knots
- D50 knots
16Which of the following will not cause an increase in stall speed?
- AA steep turn
- BA steep climb
- CA pull-out from a steep dive
- DLoading two additional passengers
17Induced drag is caused by the total reaction being inclined rearwards, when is it greatest
- AVne
- BAt cruise airspeed
- CA low airspeed
- DAs low airspeed and high angle of attack
18The aircraft enters bad turbulence. What should the pilot do?
- ASpeed up to get out of the turbulence faster
- BSlow down to just above the stall
- CSlow down to the bad weather airspeed and lower flap
- DSlow down to the manoeuvring airspeed
19A spin is
- AAn auto-rotative state with the aircraft experiencing auto-yaw and auto-roll
- BThe aircraft flipping over and over
- CA tight descending spiral at high airpseed
- DThe aircraft rolling by itself very fast.
20If the ignition switch is set to off with the engine running and the earth wire to the magneto is broken then
- AThe engine will stop
- BThe engine will keep running
- CThe engine will backfire
- DThe windings will be damamged
21Lift always acts
- A90 degrees to the angle of attack
- B90 degrees to the relative airflow
- C90 degrees to the angle of incedence
- DDirectly opposite weight
22At an aerodrome situated at 2500 feet above sea level, the take off distance compared to that at sea level given the same meteorology conditions will be
- AShorted due to the lower air density
- BShorted due to the higher engine porter output due to richer mixtures at altitude
- CGreater because the true airspeed required to produce sufficient lift is greater
- DGreater because the indicated airspeed required is higher
23Pressure decreases with altitude, and temperature decreases with altitude at the rates of
- A27 hPa per 30 feet, 2 degrees per 1000 feet
- B27 hPa per foot, 1 degree per 1000 feet
- C1 hPa per 27 feet, 2 degrees per 1000 feet
- D1 hPa per 1000 feet, 1.98 degrees per 30 feet.
