what sort of service from Brize
 

I just checked the NOTAMs for a flight tomorrow and note that aircraft flying in the Didcot and Thame areas are advised to call Brize and Benson as appropriate.

As a non transponder VFR type, what service should I ask for?

The issue is the increased traffic density in those areas due to traffic skirting the R112 and gliding at Thame and Bicester (competition in progress).

Ta, Rans6........

Whatever ATSOCAS service you want.
