[Flightgear-devel] No 0.9.9 scenery yet?
Folks: I keep hearing comments to the effect that though 0.9.9 scenery *will* appear RSN, 0.9.8 scenery works fine with 0.9.9. Is that true? There doesn't seem to be any info on the FlightGear project pages to guide users around this issue. Might it be easier to issue scenery under its own numbering system, making it clear that a given version of FlightGear needs scenery version x.y.z (or maybe = version x.y.z)? This might be an important consideration as FG goes to 1.0.0 and beyond.

For an end user app, this seems to be less beneficial. For what it's worth, we did use this version numbering scheme for a while. Officially 0.8.0 is our 'stable' release. However, as soon as we released 0.8.0 and made 0.9.0 available, *everyone* ignored 0.8.0 and ran with 0.9.x. So we tried this approach and it died a natural death of being ignored.

The reason for creating my own properties was to isolate properties that are special to the particular autopilot and to keep the properties organized. I did have some trouble finding out what properties are available. I looked through every .nas and XML file I could find in the distribution until I had a good idea of the properties I needed. I read the list of properties in the source documentation. I watched some properties in the property viewer (on the File menu).

To go partly off topic, presumably we could use the current g force to determine when the plane goes past design limits and breaks up. From the Pilot's Handbook of Aeronautical Knowledge, the different aircraft category limits are as follows. Normal: 3.8 to -1.52 Utility: 4.4. to -1.76 Acrobatic: 6.0 to -3.0 There is a safety factor of 50% on the numbers above, but it would give us a first-pass at knowing when an aircraft breaks up due to rough handling.

[Flightgear-devel] KLN89 GPS added
Hi folks, I've added a KLN89 GPS unit hardcoded in C++ (OK'd by Curt). Briefly, since it's late, it's only included on the c172p 2D panel (--aircraft=c172p-2dpanel). It looks best at --geometry=1024x768 since the fonts are at 1:1 pixellation at that resolution. As with the KAP140, it's independent of the menu dialog, and needs reference to the real life manual for proper use, which can be found on the web via Google. For non-manual readers (!), very briefly the inner and outer knobs and the crsr button are the crucial ones to get started (hit Ctrl-C for hot-spots). Inner knob changes subpage or item under cursor, outer knob changes page or cursor position, crsr toggles cursor on/off. A few flight plans are hardwired in - others can be added through the unit, but are not saved between FG sessions. Non-precision approaches for C83 and KHWD (both in the FG base package) are hardwired in and can be loaded from the APT8 page (IIRC), and the unit will simulate non-precision approach operation, including the cdi scale changes at the approach-arm and approach-active points (make sure you switch nav1 to gps on the annunciator/switch unit). Thanks to Roy Ovesen for supplying me with the svg drawings of his KAP140 as a starting point for the background.

[Flightgear-devel] Patch for 3d model_panel
Hello,
Attached is a patch for flightgear and simgear that removes the
model_panel kludge and fixes a potential memory leak.
Thoughts/comments?

If you use the --offset-distance workaround to taxi onto the white cut-out areas in, say, a cessna, you fall down to the hell. (That was a marvelous description of the problem). Thanks, I will look into that today evening. May be I can reproduce that one.

Re: [Flightgear-devel] Displaying Multiple Views/Using cockpit controls
Of course, any changes to the Getting Started Guide will only be present in the next release for most users, so we'll have a fair few questions until then... It's safe to assume that if users are smart enough to RTFM and see the local docs folder, then most of them will also check the up-to-date doc on the flightgear org site, provided the local version has a big notice that the most updated version is always to be found there. (Same as with HOWTOs). Another question is to how to drive the users to the guide in the first place, local or remote copy :-) V ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
