[Opengc-devel] nav display?

[Wendell T. <we...@ad...>]

What is the name of the nav display (HSI) shown on the home web
page?  I get blank screens when I load Boeing737NAV.

What files should be in the 'NAV DATABASE PATH'?  Should this
point to the directory with the apt.dat, etc. files?  Or one
above it?

If there is no nav data to read, or no connection to flightgear,
will that result in a blank screen for the nav display?  That
is, does the nav display need a valid position from the flight
sim?

Hi,

I've not kept up with the latest CVS version, so I'm not sure which version
you are running. If you are running an "older" version perhaps I could help,
if you'r running the latest then Damion...

Again, I've not looked at the latest CVS source, but I think Damion was
creating a generic nav display whereas the earlier version was specific.

The earlier version should work (i.e., load and display irrespective of nav
data since there were default values for LAX). But data or a connection is
NOT required to bring up the display (at least not in the earlier version)

If you are running flightgear, I might note there has not been an update to
the FG/OpenGC interface in some time

Regards
JW

The cvs version.  As I'm on a Linux platform, I only have access
to CVS; there don't seem to be older tar files around.

I don't really care which version, just any nav/hsi display
would be nice.

Ok, thanks for that piece of information.

The other displays (pfd) seem to work fine, so I have no reason
to doubt that interface.

If you go to the website, you'll see some screenshots. the latest show the
generic display, go down (back) a few pages and you'll see some earlier
(circa Feb 02) shots of the PFD/ND and PFD/EICAS.

Sorry, I don't have the latest CVS (I've been quite busy this year and not
kept up with the development) but perhaps that code is still there and you
might have to edit the make files to compile. As I recall, an entry in
opengc.ini not supported by the code is simply ignored which might account
for the blank screen

Hope this helps.

Sorry for the confusion... the name of the gauge is: NavTestGauge (note 
case sensitivity). The current incarnation of this gauge only loads 
airports and some classes of VOR's, and is best used in latitudes below 
60 degrees n/s because of the Mercator projection. I'm working on a new 
map projection system but it's not finished yet.

Boeing737NAV used a bunch of code that was incomplete (the original 
developers disappeared) so I should remove any references to it from 
the .ini file.

It should point to the .dat files - I should clarify this in the 
documentation.

If there is no nav data to read, I believe this results in OpenGC 
aborting (I haven't tried that error case in a while). If it does not 
receive a network comm from flightgear or another sim, the gauge will 
display but remain static.

Hope this helps, any other questions please let me know.

Thank you, that one looks nice.

This one is fine.

Oops, the 'NAV DATABASE PATH' must end in a '/'.  My mistake.

It just reports 'The navaid list contains 0 items' and
continues.

Yes, and thank you for your hard work.
