angle of approach or landing range question

I wasn't sure what the poster wanted -- whether he meant glide angle (as
seen from an observer on the ground) or the deck angle (as seen by a
passenger aboard). I think that he meant deck angle.

I think I meant treating the plane as a point source at its center of
mass (as done in physics class). I didn't have a glide angle and deck
angle distinction in mind, and I wasn't clear about that.

I always thought the angle was much greater before I heard about it
from a pilot. I think I had 30 degrees in mind. Tell me I'm not the
only one.
