And just to clear up Gonzo's phraseology (they don't do it much at Heathrow so forgive him!). If you are following a lander then the words are "land after the 757" not after the landed, cleared to land. If the aircraft ahead is a departure then the words are "after departing 757, cleared to land".
Ref MATS Part 1 (CAP 493), note that in the case of "land after" it is the pilots responsibility to ensure adequate separation which is why we
DON'T use the "cleared" word (hence Yellow snow your post is also a bit wide of the mark).
After the departing xxx cleared to land requires the ATCO to ensure the appropriate separation hence use of "cleared".
Extract from the good book:
When aircraft are using the same runway, a landing aircraft may be permitted to touch
down before a preceding landing aircraft which has landed is clear of the runway
provided that:
a) the runway is long enough to allow safe separation between the two aircraft and
there is no evidence to indicate that braking may be adversely affected;
b) it is during daylight hours;
c) the preceding landing aircraft is not required to backtrack in order to vacate the
runway;
d) the controller is satisfied that the landing aircraft will be able to see the preceding
aircraft which has landed clearly and continuously, until it has vacated the runway;
and
e) the pilot of the following aircraft is warned. (Responsibility for ensuring adequate
separation rests with the pilot of the following aircraft.)
The following bit refers to the after departing cleared to land. The actual procedures are individually approved for each aerodrome by the CAA and currently used(I Think) at Heathrow, Gatwick, Stansted and Manchester:
Unless specific procedures have been approved by the CAA, a landing aircraft shall
not be permitted to cross the beginning of the runway on its final approach until a
preceding aircraft, departing from the same runway, is airborne.
Lesson over. All get reading before your LCE!!!
Have a nice day
