cleared outbound for a procedure whilst maintaining an altitude
But that never happened. Quite often one was instructed to " maintain altitude 3 thousand, proceed beacon outbound" and given descent later, but that is sooooo obviously different to "cleared ..." for an approach, which soooo obviously includes both lateral AND vertical profiles
Surely the time to question a clearance is the time you get it, not some time later.
If you got "go-around" when you normally get "cleared to land" would you be unsure and query that??
