John - the real point here, surely, is that our dashing, noble young speedwinner must at some stage in his or her life flown a s/eng a/c around a circuit in other than 'wind down the runway'? In which case, what is different? As glueball said - possibly in the wrong job?
Incidentally, I did not read that the question was about distance downwind, guys and girls - just how far out
from the runway c/line to start the base turn? All part of sim and base training?
By the way, lunav - it isn't 3 x the drift! Don't confuse the young tyro.
Not forgetting, of course, that we may be talking to a flight simmer here - no clue in the profile - in which case you HAVE to use the nav display since the cat may well be in the way of the view of the runway
