ATC doesn't want you to go around if you reach glideslope intercept at your assigned altitude
ok bookworm, so just fly the localiser until you receive atc clearance to descend or if too high then ask for resequence?
Having to intercept the G/S from above was mentioned as one of the Swiss cheese holes lining up in the Turkish crash in Amsterdam.
sabenaboy, they didn't
have to "intercept the G/s from above" they elected to do so having found the a/c in that situation - an atc clearance doesn't, I am sure you will agree, absolve the flight crew from managing the approach safely. They could have said "unable ILS due height, request resequence us please"
