HRW Director is right with a number of points. Westerlies is no real problem, Easterlies would quite interesting. As it stands, approaches to RW07 at Northolt hav a 30 deg dog-leg at 4nm. At this point traffic is 3.1nm displaced from final approach on 09L at HRW. I'm sure that this problem could be adressed with systems such as MLS and appropriate 'parallel' runway type procedures.
Regarding access, the airfield is already adjacent to two seperate underground lines and the A40.
Jinking the runway onto 09/27 - not impossible but a lot of work and land purchase required.
