Obstacles are what minima are about.
There are plenty of LPV approaches to short runways, and more in the pipeline.
Obviously, there will never be a 24 LPV. The difficulty with 06 would be the missed approach, though in reality it could be designed.
As far as the housing estate goes, I trust Grant Shapps completely.
As long forecast, Biggin has made its first tentative step towards controlled airspace.
From their consultation paper, issued today:
London Biggin Hill Airport should consider the provision of Regulated Airspace to protect traffic using departure and arrival routes.
Aircraft arriving and departing London Biggin Hill Airport will likely be required to follow ‘procedurally deconflicted’ routes as they climb to 7,000ft AMSL in order to join or leave the airspace above. This means that, provided they do not deviate from a prescribed and unique route, they will not come into airborne conflict with any other traffic. This is the basis upon which modernised airspace below 7,000ft will operate in future. In order to assure safe separation of aircraft it is therefore imperative that aircraft do not need to deviate from the prescribed route – for instance in order to avoid another aircraft in uncontrolled airspace. The provision of Controlled Airspace would provide essential protection to climbing and descending aircraft through a known air traffic environment where all safety standards can be maintained.
So, with Farnborough already announced, anyone wishing to operate in the LHR/LGW corridor, including anyone using Redhill or Fairoaks will need to willing and able to pass through regulated airspace. It may be restricted by the CAA to be only an TMZ and/or RMZ, but it more likely it is a bid for Class D.
