To the best of my knowledge, only North Midlands [Derbyshire/Notts] have no autopilot at all and they have a SPIFR EC135 in the pipeline. Everyone else has stabilisation, whether the AS355 autopilot, the SAS on the EC135 CDS or the full system of the EC135 CPDS, MD902 or the lone BK117.
I've done both unstabilised and full autopilot work on v. dark nights and I know which is by far the safest when things start going wrong with other bits of the aircraft.......
