Hi Dirk

Still use here for OIRT and VOR etc but mainly summer time.

I think finding the cause of the issue rather than turning off a useful 
feature albeit underused for a large part of the year. If it was a piece 
of rogue software then hopefully it was fixed rather than turned off 
only to reappear next ctest.
