Aircraft on 'simultaneous' approach to 09L and 09R at Heathrow
Spent half an hour watching the professionals land their airliners at Heathrow at the weekend whilst there was strong northerly winds.
Noticed that although most aircraft were on 09L, there were a few on 09R as well although not not at exactly the same time , there was a gap.
Correct me if I'm wrong but aircraft cannot be simultaneously on approach on both runways whilst they are side by side as the runways are a little bit close?
So presumably it is done to get the aircraft a little bit closer spaced that would be possible on a single runway?
Is this procedure only adopted on the 09 runways as there are no noise abatement procedures like those for the westerly runways?
