Wizofoz thinks that wind is the same as no wind because all inertial frames of reference (IFR) are equally valid and he can measure a velocity relative to any IFR

The difference between these two examples is that in one the windspeed is less than the airspeed and in the other the windspeed is greater than the airspeed. In both cases airspeed is positive. In...

No not an identical force.

Vessbot you cannot be serious. Even if it is a cessna flying at 1kt in a 500 kt wind there is still no 1000 kt change of groundspeed

It does not matter whether it is an FMS turn or a HDG turn. It is a turn with a reducing tailwind component ( same effect as an increasing headwind component). The increase in performance should be a...

In the second example the math is wrong (500+1) - (500-1) = 2 not 1000

You are on the right lines talking about acceleration. Particularly that tangential acceleration is different to centripetal acceleration for an aircraft

Here you are saying that airspeed can change just because of changing head/tailwind components without a force being applied
Well that's the same as what I am saying
