Q

Assuming that fuel consumption is directly related to the power delivered by the engine, which point represents the airspeed at which to fly for maximum endurance:

A

The earliest point of the power airspeed curve

23
Q

If the stalling speed of a particular aircraft in the landing configuration (Vso) is 50kts, therefore the minimum approach speed is approximately:

A

65kts

this is 30% above 50kts

24
Q

When landing with a tailwind, the ground speed will be

A

Greater than TAS

25
Q

Assuming that fuel consumption is directly related to the power generated by the engine, what point represents the best speed to fly for maximum range

A

The middle of the graph

26
Q

An aircraft having a lift drag ratio of 6:1 will have a maximum gliding range from 5000ft of

A

5nm

6*5000 = 30000
30000 / 6000 = 5nm

27
Q

When compared to a lightly loaded aircraft, to achieve the maximum glide range in a heavy aircraft.

A

a faster speed must be used

28
Q

What is zero fuel mass

A

All passenger and cargo but no fuel

29
Q

Using a high airspeed than that recommended in the flight manual during an approach to landing will have what effect

A

it will increase the landing distance

30
Q

ice on an aircrafts wings will

A

increase weight and drag and seriously reduce the lift generated

31
Q

With all tanks full an aircraft holds 230 litres of fuel. If the Specific Gravity of the fuel is 0.72 what is the approximate weight of the fuel in lbs?

A

364lbs

Use CRP1 or
230 x 0.72 = 165.6kg
165.6 x 2.2 = 364.3lbs

32
Q

How will and uphill slope effect take off and landing

A

Decrease landing distance

Increase take off distance

33
Q

Calculate the max fuel that can be loaded and what is the centre of gravity

Max take off mass 2400lbs

A

Work how much fuel can be loaded

2400 - all other weight = 300lbs

Convert lbs to kg 300 / 2.2 = 136.4 kg

Divide by the specific gravity (0.72) to get litres

136 / 0.72 = 189.3 litres

34
Q

Calculate center of gravity postion

Total mass = 2400lbs
Moment = 49550 Lb ln

A

Moment / mass =cg

49550 / 2400 = 21.08

35
Q

On landing what is the cg position

Departure weight = 2300
Cg on departure = 85.75
Fuel burn = 300lbs (82 inches aft)

A

Moment on departure =weight x moment
2300x85.75 = 197225

Moment arm of fuel used = fuel burn x moment
300x82 = 24600

Landing moment = departure moment - fuel used moment
197225 - 24600 =172625

Landing weight 2300 - 300 = 2000

Cg position = landing moment / landing weight
173625 / 2000 =86.31

36
Q

Before refueling your aircraft weighs 1800lbs
Total moment was 151200
310lbs of fuel was loaded with an arm of 90 inches

Total moment is?
Cg is?

A

310 * 90 = 27900

151200 + 27900 = 179100

Total weight = 1800 +310

179100 / 2110 = 84.88 inches

37
Q

How does use of flap effect the approach

A

Steeper approach path

Slower approach path

38
Q

How does. Grass or snow effect ground roll

A

Brake effectiveness is reduced meaning a longer ground roll

39
Q

How does a head wind effect take off

A

Lift off at lower speed

Shorter ground run

40
Q

Carburettor icing is more likely at

A

Low power settings

When the butterfly is only partially open

41
Q

Gliding with a tail wind will

A

Increase distance covered

Rate of decent will remain the same

42
Q

When compared to still air conditions with a strong tailwind the best range speed will

A

Slower

43
Q

You have planned an early morning departure the aircraft requires a measured takeoff distance to a height of 50 ft of 350m and you calculated that the todr as 512m using a 2% upslope runway a 1900 lbs aircraft and an outside air temperature of + 10 degrees centigrade poor visibility prevents your planned early departure and by the time Departure is possible the outside air temperature is + 20 degrees centigrade and your friend wearing £190 can make the trip what is the new take of distance required

A

676m

350 x 1.1 (2% upslope) x 1.2 (10% increase in weight) x 1.1 (10 degree temp increase) x 1.33 (saftey factor)

44
Q

A small flap setting of up to 20 degrees will provide

A

An increase in lift reducing the take off run

45
Q

V2 The saftey take off speed is

A

VS1 x 1.2 and should provide at least 20% margin above the stalling speed

46
Q

An increase in gross weight will? The speed at which the aircraft rotates and? The take off saftey speed

A

Increase

Increase

47
Q

Whilst flying in the vicinity of a broken layer of cumulus cloud you notice ice building up on the wings the most appropriate action to take is to

A

Descend into warmer air or make a 180 turn

48
Q

Overloading an aircraft will

A

Slow acceleration and increase take off run

49
Q

Advice is contained in a safety sense leaflet regarding the effect of a runway surface on distances required. It states that one landing on dry grass less than 8 inches long will? The landing distance by? Landing on very short wet grass will? The landing by distance of up to?

A

Increase
20%
Increase
60%

50
Q

If an aircraft is loaded so that the centre of gravity is at the forward limit the aircraft will

A

Be very stable in Pitch and require high elevator forces during the flare

51
Q

If an aircraft is loaded so that the centre of gravity is at the aft limit the aircraft will

A

Require a reduction in elevator Force required during the flare

52
Q

With all tanks for an aircraft holds 380 l of fuel if the specific specific gravity of the fuel is 0.72 what is the approximate weight of fuel in pounds

A

602

380 x 0.72 = 273.6
273.6 x 2.2 = 601.92

53
Q

What is a gradient of a 2500 foot runway which has a threshold elevation of 355 and 460 ft

A

4.2 degrees

460 - 355 = 105
105 / 2500 = 0.042
