yeah, this is basically what I was expecting, The current auto-pilot
code is a bit hard-coded to use the radio stack for NAV modes, for
example, we need a general course deviation or heading deviation (once
we decide which) input, and then a NAV/GPS toggle on the panels, I guess.

There's a sort of sliding scale here: ranging from 1 class + lots of
configuration to no configuration but lots of classes. I'd prefer it if
the auto-pilot was broken down a little so that we could mix and match
pieces, and reduce the number of configuration options. One *possible*
sub-division I imagined was to configure separate blocks to handle each
state/mode. (with default impls of course). The the MCP/FCP buttons
would basically select a different FGAutopilotMode in as the current
(but we might need two in parallel, ... maybe FGAutoLateralMode and
FGAutoVerticalMode? not sure)
This allows people (err ... me, I guess) to write FGBoeingFLCHMode and
so on if seems necessary.
I'm open to other ideas about subdividing the code, I'm just a bit wary
of 'one big class + one big config file';

The Wilco 767: (good idea of what a Boeing FMC is like)
ftp://ftp.wilcopub/767_FMC.pdf
The KLN-89(B) manual is available here: (along with all the other Bendix
King hardware, very handy...)
http://bkweb01.ais.honeywell.com/static/bk_club/pilotguides/pilotguide.html
BTW it's 12mb, I just realized, hope you've got broadband!
Note the 767 one in particular will be rather over the top if you're new
to FMS systems (especially without an implementation to play with), it
took me quite a bit of playing the first time around to get anywhere at
all. I just purchased the PSS Airbus A320 for FS2k2, and am having to
learn this stuff all over again. Still haven't got it to fly a STAR and
approach correctly, but I think I confused it's descent planning
logic :-)
The KLN-89b is designed for GA use (and it's the 'official' manual, not
the manual for a simulation), but it also has much simpler auto-pilot
interactions (basically just driving the HSI, I think)
H&H,
