last week with a glider going directly across Gloucesters glide slope while I’m descending down it in IMC, I can understand why Exeter wanted the protection
Firstly, Exeter wanted vastly more airspace than their ILS approach protection; and more airspace than any other regional airport with fewer forecast movements.
Your anecdote is interesting - assuming you were within 10 miles of the runway that puts you below 3,000ft. How low was cloudbase for you to be in IMC? Or did you mean flying IFR in Class G in VMC ?
