Good question.
There are several options...
Firstly (most costly) NHT is re-alligned to 09/27. That would leave the 25 threshold in its current place, and possibly allow an extension to be built (as now further away from the A40. Seperation from LHR 09 arrivals maintained, but arrivals on NHT 27 would seriously conflict with LCY outbounds from 28.
Secondly. LHR Dir takes all sequencing tasks for NHT and hands over to NHT TWR or GCA when seperated. NHT then has no requirement for Radar, thus MoD save a small fortune on the upkeep of its Watchman and SSR link (Debden/LHR)
Thirdly. Flying ops cease from one of the longest operational airfields in UK history. stn based a/c move to other locations and the helis 'detach' to Battersea when required.
I would like to see a re-alignment, but who knows... the MoD will probably close the runway and consign yet another piece of this countrys history to the books.
