Perf

Question 1

The EOL is derived from what three distances subtracting 45m

Answer 1

ASDA
TODA
STODA 1.9

Question 2

V2 mustn’t be less than

Answer 2

1.1 VmCa or 1.2 vs

Question 3

What does v2 overspeed achieve

Answer 3

On climb weight limited take offs you can use the extra remaining runway to get more speed resulting in increasing Vr and improving climb performance. The cost of this is increased torr and todr

Question 4

What correction to add for slope on landing distance available

Answer 4

Specified in 4-2 if the runway slope exceeds 1% down, reduce LDA by 10% for each 0.5% in excess of 1%

Question 5

What happens to asda and todr with a higher v1

Answer 5

ASDA increas
Todr decrease

Question 6

What happens to asda and todr with a higher v1

Answer 6

ASDA increase
Todr decrease

Question 7

Why is it good to use a balanced field length where possible

Answer 7

Maximise brw on a runway that has no stopway or clear way beyond the TORA. It is when ASDA =toda

Question 8

What does a low v1 do

Answer 8

Results in short accelerate stop distance but a long 1 inop takeoff distance, useful when there is a clear way

Question 9

What does having a high v1 (close to Vr) do

Answer 9

Results in long ASDA but short 1 inop take off distance. Useful when there’s a stopway

Question 10

What do you interpolate to on average eprs for take off graph limitations

Answer 10

Nearest 1000ft PA and 5C

Question 11

40 flap max structural landing weight is

Answer 11

64650kg

Question 12

How long must you wait if quick turn around is not permitted

Answer 12

44mins

Question 13

What are the considerations for reference field length

Answer 13

Casr 121 6.02 abc
Level, dry, still air, isa at sea level, mtow

Question 14

Mzfw is related to what ,limitation

Answer 14

Wing structure

Question 15

Minimum v1 speed is

Answer 15

Vmcg

Question 16

You have an ldr of 1000m but the runway is wet.what is your new LDr

Answer 16

1150m
1000+15%

Question 17

What wind components corrections are made to normal p charts

Answer 17

Not greater than 50% hwc and no less than 150% twc

Question 18

On a 3 degree profile and you cross the threshold at 100ft.
How much longer will your ldr be

Answer 18

1000ft

Question 19

ATC requires you to maintain a particular altitude so how would you preserve maximum range

Answer 19

Fly aT optimum design speed and that speed will reduces as weight decreases

Question 20

Which is higher mrc or mlrc

Answer 20

Mlrc

Question 21

Max range speed is

Answer 21

Vimd 1.32 best tas/drag

Question 22

Correct rotation at the right Vr will ensure proper acceleration to

Answer 22

V2

Question 23

What happens to stall speed in forward c of g

Answer 23

Increase

Question 24

Clear way is 400m and stopway 100m
If the stopway became 400mt what happens to v1 and mbrw

Answer 24

They both increase

Question 25

Changes in oat effect sfc at a particular weight speed and altitude is

Answer 25

Increase in oat results in increased sfc

Question 26

Do changes in oat have significant effect on sgr

Answer 26

No

Question 27

Max range tas for a turbojet aircraft is

Answer 27

Determined by angle of attack for best gs/drag

Question 28

Max range tas for a turbojet aircraft is

Answer 28

Determined by angle of attack for best gs/drag

Question 29

The angle of attack for max endurance in a turbojet is

Answer 29

Independent of wind and weight

Question 30

In order to maintain profile for a given ias

Answer 30

You need more power in hedwind than nil or tail

Question 31

The angle of attack required for minimum thrust in level flight

Answer 31

Doesn’t vary with changes in weight

Question 32

Vr mustn’t be less than

Answer 32

V1 or 1.05 vmca

Question 33

Average tas in a climb formula

Answer 33

Anm/eti x 60

Question 34

What cg position results in lower vmca

Answer 34

Forward

Question 35

727 cg datum is located

Answer 35

Just in front of main landing gear

Question 36

What happens to tas with oat increase

Answer 36

TAS increases

Question 37

If asked best sgr without given a cruise schedule

Answer 37

Use lrc first then check faster speeds to see if there’s a faster one if headwind is strong

Question 38

Balanced field length occurs

Answer 38

When distance require Oei to 35ft is equal to asda

Question 39

Minim v1 is

Answer 39

Vmcg plus recognition time

Question 40

MLRC differs from MRC

Answer 40

MLRC is faster than MRC and involves a reduction in thrust as fuel is burnt and weight reduces

Question 41

Characteristics of fwd cg

Answer 41

Bad Increase stall speed due tail down force Increased drag Thrust required increase Range reduced Good Reduced vmca due longer arm to rudder Increased longitudinal stability

Approach attitudes with flaps Leading Trailing

Answer 42

Leading edge flaps are high attitude Trailing flaps are low attitude
