[Flightgear-devel] Fw: Multiplayer ATC aircraft, feature request...
Syd et al -- Me: I'll also see what I can come up with by way of my own solutions. I actually have hacked together an ATC version that (in my own opinion, of course) takes the best features of V1 and V2 and combines them, but also with a bigger radar screen, and the makings of a localizer guideline. I'm not the coder you guys are (yet... someday!) so I'm stumbling through a lot of the Nasal, but it's coming together better than I thought. It stores both a heading (rotation transformation) and an offset (x-shift transformation). While I haven't yet implemented the hotspots and CTRL-keys to change the settings, I have it working well enough now that if I align it with a runway, the x-shift scales with the radar scope scale setting, so it remains aligned no matter what the zoom level is. One problem I'm having right now is that it likes to extend past the edge of the radar screen. I also stole the Tower Adjust and message to target scripts -- One of my next projects is, as you (Syd) mentioned before, rotating everything into magnetic heading, to avoid confusion. I'm also thinking I'm going to add a panel of pre-canned messages as well, so within two or three keystrokes one can say, for example, MD-Terp, descend and maintain and just type the altitude on the end. I may come running to you guys to see if it's possible to select an aircraft by clicking on it on the radar scope. Let me polish off what I have so far and then I'll post some screenshots and see if you guys want to help me clean it up some. Thanks, -R. (MD-Terp) Robert M.

I think you're referring to a ground-controlled approach or GCA. However, this is not what I'm referring to -- I'm simply talking about approach controllers vectoring their planes from the end of their STARS procedure toward the localizer of the active arrival runway. Yes, intercepting it *is* the pilot's job, but the approach controller needs to get them in the vicinity of it, fare enough out, and with not too sharp a turn, and I'm pretty certain that the extended centerlines are indicated on their screens. Since I can't say this with any definitiveness, though, I understand Syd's reluctance to make changes. I'll see if I can come up with any RL references. And, as I said, I'll also see what I can come up with by way of my own solutions. I guess I'm just not patient enough for that sometimes. :) Cheers, -R. (MD-Terp) Robert M.

I was at a fly-in to an RAF base last week, which included a tour of their tower. Interestingly, they still do radar-guidance (I forget the official term) where the controller provides instructions to the pilot to bring them to the center-line and appropriate glideslope to the runway - Left two degrees, slightly high..., and the guides them all the way down to decision height. For this they had two radar displays, one showing the horizontal track and one showing the vertical, with an external center-line and glideslope marked on the display. I got the chance to try this out on their Tornado simulator, and it worked pretty well. I even got a nice print-out of my track afterwards :) -Stuart -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

[Flightgear-devel] Printing Logging Values on FlightGear Screen
Hi, I'm researching for weeks to understand FlightGear system. First, I tried to examine the source code of FlightGear project, it was hard though. Although I understood some basic things, such as which source file is needed for what, I couldn't go into details. Then, I researched the wiki page and saw that there is an API system called property tree, it can be accessed by C++, XML or Nasal scripting language. I studied Nasal a bit and learned how to use it. Actually what i want to do is that I want to print some logging properties directly on the FlightGear screen. I couldn't see any information how to print something directly on the FlightGear screen. I can handle properties with Nasal and show them on terminal but as i said i want them to show up on gamescreen. If anyone knows, can you just explain how I can do it, at least which source file? Or is there a declared API function to do that? Any help would be appreciated, thanks!!! -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

Re: [Flightgear-devel] Printing Logging Values on FlightGear Screen
I thank you dear Anders and Nicolas, Anders' method is more convenient for me because i want a permament display, from the very beginning of opening the simulator till the end. Both answers are appreciated, thank you very much. 2009/8/15 Nicolas Quijano nquij...@gmail.com Hi, You can also just open the property tree in-sim with /, browse to the desired property, shift-click on it, and it'll be on screen for that session. Convenient when you just need to check a few values that are not in your script(s) :) Ctrl-click toggles booleans from true to false.

Re: [Flightgear-devel] Multiplayer ATC aircraft, feature request...
Syd, Csaba, et al... This is by no means complete, or really even close... and I'm not done trying, but I'm just taking a little break from working on it. I just wanted to show you progress and get your input, in case there are any major problems with it so far (particularly in the Nasal). By the way, I know that the bigger radar screen obstructs most of the window, but I consider it an improvement, at least as a matter of personal preference. Your mileage may vary. http://i289.photobucket.com/albums/ll209/rmsjr1974/atcrmsjr-01-setloc.jpg http://i289.photobucket.com/albums/ll209/rmsjr1974/atcrmsjr-02-markfinal.jpg http://i289.photobucket.com/albums/ll209/rmsjr1974/atcrmsjr-03-markfinal.jpg http://i289.photobucket.com/albums/ll209/rmsjr1974/atcrmsjr-04-markfinal.jpg NOTES: When the sim boots up and initializes, the radar scope view will be set to a range of 1. Before zooming out, use CTRL-J and K to rotate the localizer guide paralell with the intended arrival runway, then use CTRL-G and H to move it left and right until aligned with it. Now you can zoom out to your preferred view distance and the localizer guide will self-adjust to remain on the centerline as you defined it. Also, please note that all heading references (on the screen and also in the data panel) are given in MAGNETIC. KNOWN BUGS / ISSUES: (1) The localizer guideline extends past the edge of the radar screen. (2) The current transformation for the radar screen actually rotates the screen itself, rather than just the indicators on it. I presume I have to connect the magnetic variation to the user's orientation in order to correct this. I think I can work that out myself, following what was done in ATC2. (3) The wind heading only updates when a target's info is updated, since I could not figure out where else in the Nasal script to put this operation. I tried to attach that script to a listener which would trigger when /environment/wind-from-heading-deg changes, but I didn't do it right, I guess. So I just threw it in the Target Update script for now. (Yes, I know that's not a great place for it!) PLANNED IMPROVEMENTS: (1) Panel hotspots to toggle and maneuver the localizer guide. Right now that can only be done with the CTRL-keys indicated above. I can add those, no problem. (2) Commands activated by either (well, really, both) CTRL-key and panel hotspots which prepare canned directives to the target plane. I want to do this in such a way that the piece to be added (i.e. which heading, which altitude, which runway) is always at the end of the message. I can manage this part, I think, based on what's already there. (3) Prettier panel and buttons. Shading for 3D effect, etcetera. I can do that on my own as well, but I just wanted to have something quick-and-dirty to test with for now. Here it is... look at it... play with it... tell me what a hack I am... improve it... give it back to me. :) LOL http://filebin.ca/mdscns/ATC-rmsjr.zip Cheers, -R. (MD-Terp) Robert M.

Re: [Flightgear-devel] Multiplayer ATC aircraft, feature request...
It's looking good so far ... I haven't tested it yet myself , but if the guidelines are a separate texture , you can have them clipped my making the instrument the same dimensions as the radar screen ... cheers -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

Re: [Flightgear-devel] Printing Logging Values on FlightGear Screen
Greetings, It may not be straightforward, but I can tell you how to send output from any JSBSim aircraft model in FlightGear to a stripchart program, which plots data at runtime. But, the stripchart program only runs on a Windows machine. It communicates via socket, so you could send the data from FlightGear/JSBSim running on any machine to a Windows machine running the stripchart application. You can get the stripchart application here: www.jsbsim.org/stripchart.zip You need to have an output element in your JSBSim aircraft definition file. I will be posting an updated version of the JSBSim Reference Manual in the next day or two. I will try to add some information about this Stripchart application. I really should modify this application to support any arbitrary data stream coming from FlightGear as well as JSBSim, because its such a darned useful tool. Im sure there are other ways to do this, too, using Matlab or something. I might be willing to send the code to someone if there is a serious desire to port it, but its an old Borland C++Builder application u sing Steemas TeeChart library.
