Refer to figure or CAP 698 Figure 3.2.

Mass: 4350 lb
Elevation: 2000 ft
Temperature: 32°C
Wind: 100/04
Runway: 34

Determine the accelerate stop distance of an MEP aircraft, fitted with heavy duty brakes in the following conditions:

  • A
    4400 ft
  • B
    3767 ft
  • C
    4620 ft
  • D
    4092 ft
Refer to figure.
With RWY34 and wind 100º/4kts, we have an angle of 120º (wind from rear right)
Tail wind component = Wind Speed x cosine (Relative Bearing)

Tail wind component = 4 x cosine (120) = -2 kts

Graphical Distance 4400 ft
Heavy duty brakes installed x 0.93 Reduce distance by 7%
Total Distance = 4 092 ft
