A and C
As a small point of order I think it can be misleading to regard a land after clearance as an instruction, because it implies you must land behind the aircraft on the runway. As we know it is wholly up to the pilot to decide whether he considers it safe to land after - in effect it is a "land at your discretion IF you consider you can safely stop before colliding with the aircraft yet to vacate"
and on that topic if a vehicle is checking the runway can AT give a land after clearance? You would have thought so, but you would be wrong.
and back to topic - what service does Leicester offer these days - is it A/g, FICO, or AT?
and Glush did you not want to tell us the type of aircraft you were flying?
