Our manual states that if we cannot issue a landing clearance to an aircraft on approach before 2 miles from touchdown then we should issue "expect a late landing clearance". This may be something historic which needs an update.
IMO it needs a review and some thought and logic applied.
IMO "expect late landing clearance" improves SA for all concerned.
How can it provide
situational awareness for the pilot on final if it lacks any information about the relevant traffic situation? The latter would convey what to look for, its probable performance, any speed difference and potential separation/wake turbulence issues. If ATC wants a preceding arrival off the runway pronto, I am sure that there would be an instruction to expedite without the pilot having to interpolate from information to another. As it stands, that nebulous (and totally unofficial) phrase could mean anything, including that ATC is just pushing his/her luck!
