ILS,
Strictly the minimum service(s) is/are FIS and Alerting Service.
TUTH,
'Management' or 'SRG'? (Assuming you meant NATS management not eJ's).
Radar,
Perhaps those living close to such airfields should be sufficiently informed to enable them to chose whether or not to travel by other modes of transport to or from an airfield within CAS?
and to all,
You're not putting lives more or less at risk, in my opinion, you are leaving yourself wide open or quite well protected from a subsequent prosecution over dereliction of duty of care.
