Big_Johnno. The Stability Augmentation System (SAS) fitted on the Koala is basically the guts of the Agusta autopilot but without the hardwear associated with the autopilot. Therefore there is no heading hold/height hold etc, but the SAS will hold heading and altitude for short periods, to look up info in manuals and flight planning docs, but eventually will deviate and will require pilot input to correct. For me it worked ok, but had Agusta offered an autopilot as an option we would definitely have taken that option. IMHO the option of an autopilot at the expense of weight/cost would have enhanced buyers choice and likely to have attracted more sales.
