Re: [Flightgear-users] DAFIF to disappear from public domain
Paul Surgeon [EMAIL PROTECTED] writes: We are not the only ones who will be affected. I know that the MSFS people use the DAFIF data as well especially for the high end addons like FMC and GPS units. I didn't know that. Perhaps MS will get an exemption, along with Jeppesen, as government contractor. However I don't see it as being a real problem since it's only for flight sim purposes. Having outdated data is not going to cause anyone to die. You'll probably find that the flight sim community will create and update their own source of data in the end. This is all very sad. I didn't find out about it until two days ago. Oddly enough, yesterday was the deadline for public comments on this, so I sent comment...

[Flightgear-users] need some information...
Hi All! In view of previous mail about using FlightGear as a GCS, i have started taking my first steps. I have a few questions and i hope some one here will be kind enough to answer them and advice. I divided my work into milestones and have a few doubts towards the strategy i use to achieve these. Please let me know if i should be rather posting this mail on the developers mailing list! 1) Write an XML file to use the generic protocol. As a first step, i would simply like to write an XML file to implement the Generic protocol, to output control surface positions and take input of position and orientation. The problem i face here is with sending and receiving data in a particular format. The control surface data vary from -1 to 1 and throttle varies from 0 to 1. My system would like an input varying from 2000 to 4000 (R/C servo friendly format). Yes, i can use factor (* 1000) and offset (+3000) and easily vary the values in this range, but the problem is that i cannot do it in integer form but only as float. How do i do it integer form. I have tried declaring as '%d', but this causes multiplication and addition to also happen in integer form thus causing a step from 2000 to 4000 directly. Further can i add the trim value to control surface value and then transmit? For immediate use, i have worked around this problem by using float and modifying the way the onboard system interprets the data received by ignoring all numbers that follow the decimal point. 2) The second task would be to add properties to flightgear. I was just reading JSBSim: An Open Source Flight Dynamics Model in C++ by Jon S. Berndt and was impressed by the flexibility that this system provided. I also read about the Property Manager but was unable to find more information about it. Can some one guide me here, show me where to look for more information and how to use it? It seemed like i could add more properties at run time using XML files! 3) Adding a new protocol to fully support my onboard system. For this i would use the NMEA protocol as a template. This step may take a long time but i was thinking about how i approach it. Any suggestions / advises? Since this protocol will be interactive, i will need to send particular types of packets and on demand. May be depending on property change that could occur from a menu option change, initiated by the user or a packet received from onboard. 4) Add menu items and windows to interact with the onboard system. Configure while on ground and control while in air! 5) Customize the HUD to show data necessary. I would here, desire to have a say, three lines of text scrolling all the commands that are sent to the aircraft, display warnings, etc.. 6) I have some amount of computation running onboard that help control the aircraft, i would like to run the same within FlightGear, so it would work like a simulator for any further experiments. I seek the expert advice of the people developing FlightGear. It could save much time and energy if some one can point out to me where to look for information on any of the above and/or which portion of the source requires to be worked on. This is a little confusing as functionality of FlightGear has been divided into sub projects like flightgear, fgfsbase, simgear etc... While working on it, i do not wish to tweak any of the existing source but to add a sub folder like say, contrib and add all source files here. but i guess some amount of tweaking will be inevitable(?) -- Cheers!

[Flightgear-users] OK I'm back what's changed?
I was on the list about 2 years ago when my old computer died and I had to wait until I could afford to get it fixed properly. I also had my inbox severely restricted by my email provider, but that's been taken care of now so I can get back on the list. So what flight models are supported now, and how is the frame rate on less than cutting edge video cards? -- Let us all bow our heads and contemplate those people stuck in traffic trying to get to a gym to ride a stationary bike. politician on the opening of a new bike trail ___ Flightgear-users mailing list Flightgear-users@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-users 2f585eeea02e2c79d7b1d8c4963bae2d

So what flight models are supported now, and how is the frame rate on less than cutting edge video cards? If you want a thorough breakdown then your best bet is the CVS logs. :) A lot has changed over the last 2 years. We have a few nice WWII aircraft (Seafire, Spitfire) quite well modeled thanks to Vivian. We have a working aircraft carrier. We have a new 3D cloud implementation (added recently) We have proper aircraft shadows (added a couple of weeks ago) Hmmm ... those are the most noticable things I can think of but there are lots and lots of behind the scenes improvements most of which I cannot remember. One such improvement is Display List support (About a 30% increase in performance) Your best bet is to get a new copy and play with it.
