Can someone elaborate on the formula GAG=GAA(airspeed +/- wind)/airspeed

I'm a little confused on what GAA is and if it's just a constant number. I
kind of derived it as being 30 degrees as a constant target of angle you
want to the touchdown point (?). it works for Tom Knauff's calculation in
his book with 50mph a/s and 30 mph headwind, and using 30 for GAA. but when
I reduce it to a 5 mph headwind the resultant doesn't come within the cone.
Am I missing something here?

You're making it way too hard. Just set your flight computer to 0 altitude
at the threshold. "Call the ball" and follow the needles. There's no actual
need to look outside anymore.


















This being R.A.S., it's sad but true that it's necessary to point out the
above was sarcasm.
