212 - The FMS is a CMA3000 made by Canadian Marconi, though later aircraft will have the CMA9000 which is a later version of the same thing.
From their web page "
The CMA-3000 is a compact flight management / radio management system well suited for fixed and rotary wing aircraft requiring performance, but having space and weight constraints." whatever that means!
We supposedly have a worldwide (European at least) database and it seems to have everything in it for all airfields except those north of Edinburgh. Duh! Of course the contents of the database are not the fault of CMC but there seem to be very few providers of customised databases in the vicinity and our current provider is unresponsive.
You say your UNS can do NPA approaches - does it have TSO 145 GPS receiver? If only TSO 129 I don't think you would be allowed to do NPA approaches with gps as the sole aid in most of the world (except USA).
...with even a 6 kt crosswind capable of generating in excess of half scale localiser deflection close to minima...
225 is amazing in that area - one night I was flying training ILSs into EGPD RW16 with wind at 2000' 75kts at 60 deg right of final approach track (coming over the hills) with ATC man giving real-time surface wind callouts as they like to do. It went like this "....50 kts.....5 kts....50 kts..." etc - kind of gusty! We had to slow to 130 just to reduce turbulence so that we could see the instruments and avoid physical damage with parts of the cockpit, but ILS needles remained dead centre all the way. Afterwards Eurocopter man said they had decided to always paint the needles dead centre regardless, but I think he was joking!
Afterwards ATC man was heard to pass comment that whilst the 737s had been exploring the ILS envelope, the 225 came in right down the middle (they monitor with radar)
That's what an inertial autopilot does for you and personally I would not trade that for a gadget that sets the final approach track for me!
