Brize LARS Hours are (As per the BINA):
0800(L)-2000(L) Mon-Fri
*Outside these hours, subject to controller workload.
I understand that these hours have at last filtered through to some civil documents. Though dont ask me which ones.
I have no idea what the "BINA" is. There's only one publication that matters for civil pilots, and that's the AIP. ENR 1.6.3, last updated 8 May 2008 says:
6 ATS Units Participating in the Lower Airspace Radar Service
...
Brize Norton Position: 514500N 0013500W Frequency: 124.275 Service Radius: 60 Availability H24.
If that is
not the case in reality then someone needs to get the AIP updated.
BookWorm - Try calling up as 'Ascot' and see what happens
Tempted though I was on Tuesday and Wednesday, using my normal callsign I got the usual exemplary level of service from Brize, for which, as always, I'm most grateful.
