If you're not cleared descent on GP then you don't descend and if necessary ask to be resequenced or carry out a Go Around - surely you'd want to ensure safe clearance from other traffic?
But this is the irony of the current phraseology. ATC doesn't want you to go around if you reach glideslope intercept at your assigned altitude and haven't got a "descend with the glide instruction". The glideslope itself is inevitably clear. The phraseology is intended to prevent descent
below the glideslope when the initial clearance (in the UK to "intercept the localiser", everywhere else "for the ILS") is given.
I have a dream... the same procedures and phraseology all over the world.
Indeed. Perhaps NATS and ATSD should get out more.
