Absolutely. There is a strong need for a dedicated LARS unit to cover the Open FIR below 2,500ft underneath the TMA North and East of the Heathrow and City CTRs
This is made all the more important by the presence of Biggin Hill's instrument approach and the fact that the ALKIN hold extends below CAS.
But of course with privatisation we ain't gonna get it. At least until there is a spectacular mid-air and the press starts asking 'why weren't they talking to a radar controller?'. Because Thames Radar, Heathrow Radar, Essex Radar and Luton Approach can't provide LARS anymore.
