But actually reading your post again, it may just be the 'alternation'
when we changed from the Southerly Runway (27L) to The Northerly (27R)
for landing at 1500L This only occurs on Westerly operation ie landing
over London from the East to the airport. On Easterlys we i.e landing
over Windsor we always land on the Northerly (09L).

Phil - I'm assuming that the Northerly/Southerly runway are quite well-
spaced given the dislocation of the incoming aircraft from the pre-3pm
flight path?
