Proline 21 Very pretty to look at... seems under developed compared to the airliner avionics I've used before, particularly the FCC software.
Our CL 605 seems unable to capture a LOC cleanly, either in NAV to NAV transfer or 'green' source selected 'it' turns to a 30 degree intercept (normally fairly aggressively), sits there wobbling/rocking the wings for a while and sometimes changing heading by 5 degrees or so.. before finally 'pinning' the localizer... is this normal for this bit of kit?? Aerials have been checked... Can't remember the B737 or 757/767 avionics having these capture problems.
AP FLC mode has a nice and pronounced 'porpoise' effect when the speed drops 1 kt slow... passengers must love it... requiring the use of V/S or pitch to smooth things.
Can't view the co-located ILS DME read out without 'green' source being selected on PM/PNF side.. retrograde step from CL 604.
The most heard phrase on our flightdeck regarding the autopilots handling abilities is.. 'Ooo what the hell is 'it' doing now!' normally with some hilarity..
Underdeveloped or just our FCCs (all 4)??
I do like the VGP function.. works very well.
