Calculations and Figures

Question 1

Required track miles for descent

Answer 1

Cruise FL (thousands of feet) x 3 + 10

e.g. Cruise FL350 - 35x3 + 10 = 115NM from TOD to destination

Question 2

Wind Additive for VFLY (when gusty)

Answer 2

Wind additive = Half steady wind + [gust factor]

(Up to a maximum of 15)

[Gust factor = Gust wind - Steady wind]

e.g. VREF = 140 and wind is 250/12G26

6+14=20 (this is greater than 15),
so VFLY = 140+15 = 155kts

Question 3

VFLY (light winds)

Answer 3

VREF + 5kts

Question 4

Limiting Speed for Flap 1

Answer 4

250kts

Question 5

Limiting Speed for Flap 5

Answer 5

250kts

Question 6

Limiting Speed for Flap 15

Answer 6

200kts

Question 7

Limiting Speed for Flap 30

Answer 7

165kts

Question 8

Power/Pitch settings for Initial Climb

Answer 8

N1: As Take Off ref page

Pitch: 15 degrees, then pitch for V2+20

Speed: V2+20

Question 9

Power/Pitch settings for Level, clean - UP

Answer 9

N1: 55%

Pitch: 5 degrees

Speed: -UP

Question 10

Power/Pitch settings for Gear down, flap 30, 3 degrees G/S (VREF+5)

Answer 10

N1: 56%

Pitch: 2 degrees

Speed: VREF + 5

Question 11

Circling Approach Timing for Downwind leg - Abeam Threshold

Answer 11

3 x 100’ AGL - 1/2 TWC

(3 seconds per 100’ AGL) - half of the tailwind

Question 12

Circling Approach Timing for Crosswind track - 45 degrees

Answer 12

20 - 1/2 TWC

Break 45 degrees and fly crosswind track, timing from wings level
