Re: [Flightgear-devel] Printing Logging Values on FlightGear Screen
Ive posted a new version of the JSBSim reference manual with much more included on input/output and scripting. You might be interested in the part on the stripchart application I described below.

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] 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.

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) :)

Hi,
It's is easy to do that from Nasal via the module screen.nas.
Example for a JSBSim aircraft (you can e.g. run it in the Nasal console
available from the debug menu):
var left = screen.display.new(20, 10);
left.add("/orientation/pitch-deg");
var right = screen.display.new(-200, 10);
right.add("/fdm/jsbsim/propulsion/engine[0]/propeller-rpm");

right.add("/fdm/jsbsim/propulsion/engine[0]/thrust-lbs");
right.add("/fdm/jsbsim/propulsion/engine[0]/boost-psi");
With the developer extensions enabled (also in the debug menu) you can
also find any property via the '/' key and display its value by pressing
enter, or put it on-screen by pressing '!' (or open the propert browser
by pressing ':').
Cheers,
Anders

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.
