Thanks Ron!
I discovered my mistake after looking at the Concorde config for an hour.
The instrumentation config file has to be included inside the  tags 
otherwise the  tag is just treated as a property.
So there is a need for two  sections in a set file. One 
inside the sim section and one outside the sim section.

Sure, it's generic to military aircraft but does that mean that all civilian 
aircraft in FG should have TACAN as well?
Why aircaft like the j3cub must have  tacan, KT-70, wxradar, mk-viii by 
default is beyond my reasoning capabilities.  :)

And why are two nav radios and comms radios set up in the generic config and 
not two dme devices? There are far more aircraft with dual DME devices than 
there are aircraft with TACAN capabilities.

And then there is the mk-viii which should never have been added to the 
generic config since it's used on a very small percentage of aircraft.

Paul

An aircraft's local instrumentation config file is just a replacement
that overrides Generic/generic-instruments.xml, so in principle, if it
does not work with the local config file it wouldn't work any better in
generic.instruments.xml.

Remember that you also have to supply power to your new DME, and that
the serviceable property should be set to "true".

When I created the generic-instruments.xml file I included whatever
existed hardcoded at the time. Since then new instruments have been
added. It would be preferable if every aircraft had its own customized
instrumentation config file (and systems config file).

It works for the Concorde in 0.9.9, I just checked.  It has an aircraft
specific Concorde-instruments.xml containing (among other things)


  
dme
0
  

  
dme
1
  

and loads it from the concorde-set file with :

  
   Aircraft/Concorde/Systems/Concorde-instrumentation.xml
  

Then uses it in Aircraft/Concorde/Panels/Instruments/concorde-dme.xml

TACAN is every bit as generic as DME or VOR.  Every military aircraft
produced since about 1950 has had a TACAN set installed.

[Flightgear-devel] generic-instruments.xml and a second DME device

2006-03-22 Thread Paul Surgeon
After some debating in IRC ...

Can we please add a second DME device to Generic/generic-instruments.xml?

i.e.
  
dme
1
  

It is ***NOT*** possible to create extra devices within an aircraft's local 
config files. I've tried it and it does NOT work.
All you end up with are some properties but nothing that drives them.

The majority of large airliners have a DME device per NAV radio and don't 
feature DME switching between NAV 1 and NAV 2 like a lot of the smaller 
aircraft nav systems have.
At the moment it's impossible to have two DME distances displayed in a 
cockpit.

If the tacan, KT-70, wxradar, mk-viii which are not generic can live in 
generic-instruments.xml then I see no argument against a second dme 
instrument living in there too especially if that's the only place to do it.

Thanks
Paul
