I can't make any promises as to time, but I'll take gradual stepstowards getting a copy of the code on my machine and diddling with it.Is there a real helicopter pilot on the list who'd be interested in taking my changes and saying yes, this is realistic or not onanything I've ever flown? I can help u with that, i fly a ec-120 for cpl(h) certification.. now i have ~ 50 hours... i think i can give you a clue. I also dreamed about improving the helicopter code for FG, but my programming skills are limitated, so i'm looking forward to your work. I will take a look at documentation and see if i will be able to develop a model of ec-120 to use your code. X-plane, have so far the most realistic helicopter model, i was tring to develop the ec-120 for x-plane, but does not offer suport for FENESTRON and i gived up, as far as i remember neither FG has FENESTRON support. any way... i'll give it a try.

The only reference point I have, is a few weeks flying the Bell 206 in Microsoft flight simulator, and that was 5 years ago, but in Fligh Gear, I feel that two things are wrong. I'm not yet a real helicopter pilot, but i managed to optain a scolarship to be trained to ATPL (H) Level, teoretical and practical. Wright now i'm o teoretical part until 1'st of May when the fling part begins. I also advanced a project to my aviation academy to permit finance us (the helicopter clas) to build a heli sim based on FG (mybe will be aproved by JAA), i'm waiting an answer from them (but the big problem is absence of autorotation in FG :(. ). From may, i can compare FG with realthing and help you with improving FDM for heli... also, if the academy will accept my project i will have a group of flight instructors with a vast experience in many helicopter types, as betta testers and critics for our simultaor. In any case, you can count on my help soon. ps i will fly EC 120 155. this is my academy: http://www.aviationacademy.ro/english/index.htm IS ___ Flightgear-users mailing list Flightgear-users@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-users 2f585eeea02e2c79d7b1d8c4963bae2d
Re: [Flightgear-users] Re: Flying Helicopters ?
I'm afraid that fgfs is not suitable for helicopter training yet. Autorotation isn't the only thing that's missing. Ground effect and a few other effects aren't implemented either. I knew that... but i was hoping... this is the reason for way i mentionated X-plane too in my project, The FDM author knows pretty exactly what is missing[1]. He knows experienced real-world helicopter pilots, even bo105 pilots (one of which is AFAIK the head of all bo105 helicopters issues of the German army). What is missing now isn't so much good advice, but someone who knows enough physics and mathematics to implement it! (The original author hasn't had time since a great while.) :( I was hpoing to be usefull, i don't have a good skill in writing code, i tryed once to imiplement a flight planner for FG, in Java, but it was to complicated for my skills. I would love to be able to imporve the Yasim's FDM but i'm not :( A different matter is the 3D representation, the bo105 model. I'm not a helicopter (or other) pilot and I can still be taught a lot. (Just spare me comments about how the bo model should be textured etc. If anyone knows that, it's definitely me! :-) About 3D representation af AC, i'm not demanding much... i'm flying from cokpit ;) IS ___ Flightgear-users mailing list Flightgear-users@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-users 2f585eeea02e2c79d7b1d8c4963bae2d
