Tower controllers had problems with 27R departures as vortex effect had to be avoided with traffic on short final for 23.
Wow that would be a windy day for the paths of the typical types using Heathrow to cross.
Missed approach off 23 versus something like a FK50 departure off 27L I could understand the posibility but would there be anything operating from 27R that would rotate before the centerline of 23?
