"If you begin descent when ten miles from DEPRE you've busted your

DEPRE."

I thought the last instruction was "AWI123 cleared ILS runway three six
contact tower one one eight point seven." You may not be able to
intercept the glideslope from 3000 (e.g., if the signal is weak there),
which is why I suggest descending.


You might want to read the scenario again. The approach clearance was
issued when the aircraft was five miles from DEPRE, so when you're ten miles
from DEPRE that hasn't happened yet. When ten miles from DEPRE the last
instruction was indeed "descend and maintain 3,000, join the runway 36
localizer". When you're five miles from DEPRE you're about 700' below the
glideslope and less than tem miles from the GS transmitter. The signal is
fine.
