Intial T/o Climb

Question 1

NADP is not advisable when

Answer 1

The r/y surface is contaminated
Horizontal visibility is less than 1.9km (1nm)
The crosswind component including gusts exceeds 15kts
Wind-shear has been reported
Ts are expected to effect the aprch or dep
The a/c has suffered an eng failure and system failure

Question 2

2 different NADP

Answer 2

1 - noise sensitive area is close to r/y

2 - noise sensitive area is distant from the dep end of the r/y

Question 3

NADP 1

Answer 3

Starts at screen height

After SH V2 + 10kts and TOGA till around 800ft

Maintain V2 + 10kts till 3000ft, nose is pitched down and a/c accelerates while maintaining a positive roc

After 3000ft - flaps retracted and accelerate to cruise

Question 4

NADP 2

Answer 4

Starts at SH

From SH to 800ft, V2 + 10 and TOGA

From 800ft, push nose down and accelerate while retracting the flaps, still on TOGA

On reaching Vzf, reduce to MCT and increase ROC to cruise

Question 5

NTOFP

Answer 5

Assumes engine failure at V1

4 segments - all based on 1 eng inop

All figures are gross

Question 6

NTOFP segments

Answer 6

Seg 1 - getting the gear up to SH (15ft or 35ft), on TOGA thrust min speed = Vlof

Seg 2 - all about climbing to clear obstacles, up to a min 400ft, on TOGA thrust, min speed = V2

Seg 3 - has variable height depending on acceleration and height covered in 10mins, flaps are retracted till Vzf, nose is lowered to gain acceleration, on TOGA thrust, will reach Vmd ish by the end

Seg 4 - MCT to 1500ft, bigger roc

Question 7

Seg 1 min climb gradients gross

Answer 7

Twin eng = positive climb gradient (0%)

3 eng = 0.3%

4 eng = 0.5%

Question 8

Seg 2 min climb gradients gross

Answer 8

2 eng = 2.4%

3 eng = 2.7%

4 eng = 3.0%

Question 9

3rd segment min climb gradients gross

Answer 9

2 eng = 1.2%

3 eng = 1.5%

4 eng = 1.7%

No climbing in this segment but it can prove you have excess thrust

Question 10

4th seg min climb gradients gross

Answer 10

2 eng = 1.2%

3 eng = 1.5%

4 eng = 1.7%

Question 11

Max time in TOGA

Answer 11

10min

Question 12

Safety factor to add to gross climb gradients to get net

Answer 12

2 eng = 0.8%

3 eng = 0.9%

4 eng = 1.0%

Question 13

NTOFP - turning

Answer 13

A turn must not be commenced below 50ft or half the wingspan - whatever is greater

Question 14

NTOFP AoB

Answer 14

Angle of bank may not exceed 15* below 400ft

Above this, class A a/c may not exceed 25*

Question 15

NTOFP Obstacle clearance

Answer 15

Vertical distance of 35ft or 50ft in a turn
Or
60m + 1/2 wingspan (up to 90m) + 0.125D where D is the distance the a/c has travelled from the TODA

Question 16

NTOFP - max dep sector width with no req track change

Answer 16

300m - if the pilot is able to maintain nav accuracy through the obstacle accountability area

600m - for flights under all other conditions

Question 17

NTOFP - max dep sector width with a req track change

Answer 17

If the req flight path track change is more than 15*

600m - if the pilot is able to maintain the req nav accuracy through the obstacle accountability area

Or

900m - for all flights under other conditions
