An aircraft flies from A to B, distance 155 nm, in 1 hour and 23 minutes. If there is a tailwind of 12 kts the TAS is?

  • Are you unable to calculate the ground speed from that information? Basic algebra. – KorvinStarmast Mar 17 '18 at 19:01
  • How would you calculate the speed of a vehicle from time and distance information when there is no wind? – Cpt Reynolds Mar 17 '18 at 19:15
  • The TAS is not affected by the wind. The aircraft flies within the mass of air, and the TAS is the speed of the aircraft with respect to that mass of air. The only speed affected by the wind is the groundspeed... – xxavier Mar 17 '18 at 20:57

Try this: (a small amount of rounding, not considering instrument error -basic)

Speed = Distance x 60/Time (in minutes)

Speed = 155 x 60/83(minutes)

Speed = 112 nmh

Speed of 112 nmh consists of 100 kts TAS and 12 kts Tailwind.

Then, TAS = 100 kts.
