Thanks James.
It seems to work with my test buzzing london and associated VOR/ILS
am now trying to refine autopilot in concert.

Ok, and then the final step is the bits.test(bar,0). I spent a couple of
minutes searching the web but could not find docs for the bits.test
function. I assume bits.test(oddnumber,0) returns 1 and something else
for even numbers, presumably 0?

Committed now - also made the same fix for 'has-gs' which was similarly getting
stuck on the old value when no valid station was tuned.

I can't read Nasal so I can't say if the function below is correct. For
what it is worth: A frequency between 108.100 and 111.950 (including end
points) is a localizer frequency if the first decimal is an odd number.

Nasal is like C, C++, perl, and php in many ways so if you can read any of
those, you should be pretty confident that what you think nasal is doing is
what it's actually doing. Writing nasal code from scratch is harder of
course because it requires knowledge of all the picky language syntax
For me the Nasal function looks strange. I can't understand what the
addition of 0.001 to freq does? For me it seems to be a waste of
precious CPU time.

I wouldnt spend too much time on the b1900d , as Ive already redone most of
it ,and added the CLM /DSC modes , and will probably commit tonight .
OK, I tuned only implemented modes on old aircraft :)
My patches are only suggestions
The main problem
Yes Ive sorted some of that out .
What makes it a bit more difficult is that all pitch modes have to be output
to target-pitch-deg to run the flight director bars .
If you want to experiment with the version I just uploaded , I'm sure it
could be greatly improved.
But I'd prefer if you posted
you can also check the instrumentation/nav/nav-loc , but it seems to stay

Hi!
I would like to join the discussion about AP tuning. I recently posted
a message on the forum
(http://www.flightgear.org/forums/viewtopic.php?f=4t=6853) for
b1900d. With enclosed files, action is quite smooth and autopilot
seems stable, at least on my conputer.
For vertical stabilization
I wouldnt spend too much time on the b1900d , as Ive already redone most of
it ,and added the CLM /DSC modes , and will probably commit tonight .
The main problem i found on that is the yaw damper was fighting any turn in
roll modes,so at the moment Ive disabled it.
I'm still tuning the pitch
Wonderful, brilliant stuff Giuseppe,
The way that the autopilot works with those patches is the way I expected.
Hope this stuff makes its way into CVS so at least there's a good
reference implementation.

Is one of you aircraft in CVS so I cant study the autopilot.

Would it be possible to wire up the VNav autopilot as follows, or is it
a bad idea.

the pids, which would mean taking into account the current elevator
