Answer 3

IAS will decrease and rate of decent will increase

Question 4

Partial extension of flap in a glide at constant IAS will result in …..

Answer 4

an increase in rate and angle of decent

Question 5

The best angle of climb speed for a particular piston engine aircraft is 65kts IAS. What could reduce this best angle of climb …..

Answer 5

a decrease in IAS or a tail wind

Question 6

A pilot assesses that he is undershooting the selected field while on final for a forced landing in nil wind at the best L/D ratio speed. The safest procedure to employ is to …..

Answer 6

maintain the present nose attitude and airspeed as there is no better than the best L/D ratio

Question 7

Describe the effect of an increased headwind during a steady climb with constant IAS and constant power maintained …..

Answer 7

rate of climb remains the same but the angle of climb increases

Question 8

The effect of fitting an aircraft with a more powerful engine would be most noticable during …..

Answer 8

a max rate climb

Question 9

When manoeuvering at low level on a windy day the pilot should be aware of the following illusions …..

Answer 9

Slipping into a turn when turing from upwind to downwind

Skidding when turning from downwind to upwind

Question 10

If nose attitude and power are kept constant, a sudden decrease in headwind during the final approach will initially cause …..

Answer 10

a decrease in IAS and an increase in the gliding range

Question 11

Describe how increased weight effects the maximum gliding performance in nil wind …..

Answer 11

the speed for best gliding increases and the gliding distance remains the same

remember the picture of the black and white planes on the slope. The heavier one gets to the bottom faster but they both go the same distance in nil wind.

Question 12

if angle of bank and IAS are kept constant, an increase in altitude will cause …..

Answer 12

an increase in the radius of the turn since the density is less the TAS must be higher when compared with the lower altitude turn

Question 13

An effect of lowering full flap during a descent is to …..

Answer 13

increase both the lift and drag

Question 14

If the headwind component suddenly decreased in a decent …..

Answer 14

IAS would decrease and rate of decent would increase

Question 15

The IAS at which the stall occurs during a 75-degree banked level turn would increase over the level flight stalling speed by approximately ……

Answer 15

100%

remember that stall speed increase with the square root of the load factor. since the 75-degree turn is a load factor of 4 the square root is 2 so it is 2 times faster which is 100%

Question 16

Relating to turn radius

2 planes identical in every respect except for gross weight, carry out a balanced level turn at the same IAS and anfle of bank. The heavier aeroplane will …..

Answer 16

the same radius of turn and the same rate of turn as the lighter one

Question 17

What will be the effect on turning performance if IAS is increased during a level turn at a constant bank ….

Answer 17

the rate of turn decreases and the radius of the turn increases

Question 18

The angle of bank required to perform a rate one turn at a TAS of 180kts is closest to ….

Answer 18

25⁰

Question 19

During a steady descent at a constant IAS thrust is …..

Answer 19

less than drag

Question 20

During a glide forced landing the pilot is maintaing the best L/D ratio but realises he is undershooting. The best course of action would be to …..

Answer 20

maintain the current decent attitude to acheve max gliding distance.

Take what you get at best L/D since there is no better

Question 21

The limit to the rate of turn that can be acherved by a typical GA aircraft is governed by …..

Answer 21

the amount of power available from the engine

The load factor at high angles of bank are accompanied by a dramatic increase in drag as well as the stalling speed. This must be over come by applying extra power but a light aircraft runs out of power and can no longer maintain the speed at or beyond the stalling angle.

Question 22

The load factor limit is most likely to be exceeded during a level turn if the angle of bank is ….. at a speed ……

Answer 22

increased, V_a

Question 23

Abrupt control movements are likely to impose excessive stresses on the airframe if they are made above …..

Answer 23

V_no

Question 24

If power is increased during a turn while maintaining the stalling angle of bank what happens to the radius and rrate of turn …..

Answer 24

Radius of turn will remain the same and the rate of turn will increase.

Remember if the angle of bank remains the same then the radius of the turn will stay the same.

If power is introduced then the turn will be completed faster so the rate of turn will increase.

Question 25

An aircraft entering ground effect on landing will experience ….

Answer 25

1. Nose pitching down
2. Increased longitudinal stability
3. ASI and Altimetre under-reading
4. Decrease in induced drag

Question 26

An aircraft leaving ground effect will experience …..

Answer 26

1. Nose pitching up
2. Decrease in longitudinal stability
3. Over-reading of ASI and altimetre
4. Increase in induced drag

Question 27

What does ground effect do to wing tip vortices and induced drag …..

Answer 27

Vortices decrease and induced drag decreases also

Question 28

While maintaining a constant angle of bank speed is increased. What happens to rate and radius …..

Answer 28

Rate - Decreases

Radius - Increases

Remember if the speed increases the AoA will increase so to keep the turn level with more power you will need to lower the nose or reduce back pressure

Question 29

While maintaining a turn with a constant angle of bank, speed is increased. What happens to rate and radius …..

Answer 29

Rate - Increases

Radius - decreases

Question 30

During a turn with constant bank power is increased. If level flight is to be maintained lift would ….. and back pressure would need to …..

Answer 30

lift remains the same and back pressure needs to reduce.

Since we are trying to keep the level turn more power increases the lift whcih needs to be countered with the relaxing of the controls and AoA.

AoA must reduce to keep the lift the same as before the power was applied.

Question 31

During a level turn bank is increased. If the IAS is to remain the same the pilot must ….. the AoA and ….. power to balance the ….. in induced drag

Answer 31

increase the AoA, increase power, increase in induced drag

Question 32

During a prolonged climbing turn to the right the pilot will need to apply

Answer 32

right rudder and left aileron

Question 33

During a climbing turn to the left, the nose is raised until the stall occurs. Describe the most likely consequence …..

Answer 33

The right wing will stall first and the aircraft will roll abruptly to the right

Question 34

Select the types of motion occurring during a level turn …..

Answer 34

Pitch and Yaw

Question 35

A slow aircraft and a fast aircraft are carrying out a rate 1 turn at the same height. The slow aircraft would need ….. bank and would turn in a ….. radius

Answer 35

less, smaller

Question 36

During a balanced medium decending turn the inside wing has the …… AoA but there is ….. tendancy to …..

Answer 36

greater, no , over or underbank

Question 37

During a turn at low level on a windy day the pilot should be aware of the illusions that make him feel as though he is

Answer 37

Slipping into the turn from upwind to downwing

Skidding out of the turn from downwind to upwind
