Thanks for your help but I am still not getting it!
I understood that, when the aircraft is in the air, a headwind, (or tailwind) has no effect on TAS?
I thought that an aircraft in the air is analogous to walking on a conveyor belt.
If the conveyor belt is going forward or backwards it makes no difference as the only thing that matters is your relative speed to the conveyor belt as though it were still? To complete the analogy, the speed of the conveyor belt (wind speed) only affects the speed of the object on the conveyor belt relative the ground?
I'm struggling to understand how the wind can contribute to TAS on the ground (and shorten takeoff) and then once in the air have no effect on it?
Would really appreciate any help.
thanks
