My guess is that one of the key factors which may test them will be whether their ops manual requires them to have a Deconfliction Service outside CAS. If it does, they'll regularly get vectored al over the shop by Brize, who will then dump them on to non-radar Oxford
Unfortunately, at the flight times published 0800 out and 1830 back, Brize will not be operating (they are now LARS 0900-1700 - 7 days per week!) so it'll be APC to and fro Airways! Also, due to the relatively short flight times from CPT & DTY, Oxford work most of the commercial traffic both to and from Airways; unless Brize or Benson wish to work the traffic if they have specific (deconfliction Service) traffic to affect.
Traffic loading at these times is 'normaly' light. The only conflictor will be the 'Traffic Survey' C172 :-).
