One of the three, at least, will be in use for take-off only. It
ought to be possible for the aircraft on the middle runway approach
to turn towards that other runway and do a circuit in that direction.

However at LHR the proposed third runway is a short one, and so
presumably will be used by smaller aircraft for both landings and
take-off.

Two outside runways have simultaneous take offs - I very much doubt they
will be turning towards one another, therefore the landing on the center
can
go straight on!

We're not talking about a landing, but the need to "go round again" if the
landing has to be aborted. This is unlikely to happen later than when the
captain calls finals, when he will be a couple of miles away from the
threshold, at least.

Last time this happened to me (Dublin) we were over the threshold when the
pilot aborted. Apparently an Aeroflot plane had, quote: 'Got lost' and
hadn't cleared the runway when expected to. We went up in a straight line
and much steeper than a normal take-off. I've also seen go-rounds at
Heathrow happen much closer than two miles from threshold.
