You are correct that a 3 degree flight path with a fixed aiming point is fixed in space; I did not dispute that. However to maintain that with any wind, the variable is power. In a strong tailwind there will come a point where this is not possible as the power will be at idle. Of course, the way to maintain the flight path now is to point at the aiming point as the tailwind tries to put you above the profile. Should one arrive at the aiming point at the correct height, you will certainly be fast and….. you will land long. Professional pilots call this an unstable approach.
