20 / 20

Given:

Hdg 230°T
GS 340 kt
W/V 270° / 40 kt

Calculate the Track and TAS.

  • A
    Track = 226° ,TAS = 370 kt
  • B
    Track = 225°, TAS = 310 kt
  • C
    Track = 234°, TAS = 308 kt
  • D
    Track = 234°, TAS = 371 kt

Refer to figure.

Determining track and TAS with the flight computer:

  1. Set wind direction under "True Index" => 270º
  2. Chose any convenient datum to measure from (ie 340 kts), under grommet in the center of the wind face. Plot the wind speed downwards (6 o'clock direction) => 300 kt
  3. Set your heading under "True Index" => 230º
  4. Slide Wind Velocity Mark to Ground Speed.
  5. True Airspeed TAS reads under centre => 370 kt
  6. Drifts reads between the center line and the TAS mark => approx. 4ºL
