1 Nop, the moment you make your turns relative to the air, your ground speed (vector) will vary and as such, you will experience (minimal) accelerations.

For holding, etc, it's ground based (fortunately). But now we are discussing the wind effects on airspeed and kinetic energy, based on assumed manoeuvres.

Wow, what a confusion.

Actually, when you "turn" through a wind field/direction, you get "blown" away. This blowing away, will take care, the wind will increase your kinetic energy. Though, this...

Looks to me, the video shows happening what I described. Though just at the end of the turn to final, where I expected this to happen a little earlier, more at 2/3 of the turn to final.

Maybe read again, what I wrote.....

You think in speed. That's the wrong approach. You need to think in Kinetic Energy, and that is ground reference based. When you turn final with Kinetic Energy...

Sorry, I oversaw the base leg approach with short final for MGQ.

I don't think, this was an "undershoot".

When there is a landing tailwind of (for example) 20kts, and one does approach on the...

A headwind, reducing close to the ground, will let you drop out of the air due to insufficient airspeed, whereas a tailwind, reducing close to the ground, will increase the airspeed and as such,...
