John Dow Posted January 19, 2011 Share Posted January 19, 2011 I've fiddled a bit with the air file and the aircraft.cfg file for this release to try and get a bit of 'weight' back into the landings. For me the flight model floats too much in the last 20 feet or so, I've made some minor alterations to the ground effect, flaps drag and wing area to make it feel more like I would expect a twin with a high wing loading would behave. Here's a video of a long stable approach into Friday Harbor that for me feels about right: I've uploaded a file with my tweaks to Avsim, search for C340Mods.ZIP in the next file library update.

rockliffe Posted January 19, 2011 Share Posted January 19, 2011 Hey John, that's interesting. I'm not a real world pilot but have had occasional experience with flying and my initial concern with the C340 was the strange ground effect on landing. It may well be accurate, I don't know, but I will try out your tweak, thanks a lot EDIT Just been on Avsim John but cannot find the file. Forgive me, but where exactly should I be looking? Next file library update? Link to comment Share on other sites More sharing options...
John Dow Posted January 19, 2011 Author Share Posted January 19, 2011 I only uploaded it last night so I assume it will have to wait to be vetted. If it doesn't appear today I will upload to flightsim.com where at least I know it will appear. Link to comment Share on other sites More sharing options...
John Dow Posted January 20, 2011 Author Share Posted January 20, 2011 UPDATE: OK Avsim had a whinge because I didn't put my email address in the readme file, so it seems you won't be able to download the two modified files from Avsim after all. However, as they are tiny files and won't upset the system here, I'm attaching them to this post. I have also uploaded the zip file to flightsim.com it's called C340Mods.zip and it should be there tomorrow. I would love feedback on these files, they work for me but I haven't exhaustively tested the effect on other aspects of the flight model. Link to comment Share on other sites More sharing options...
rockliffe Posted January 20, 2011 Share Posted January 20, 2011 Well done John, thanks a bunch. I'll look forward to trying those later. I'll let you know how I get on Link to comment Share on other sites More sharing options...
Guest Posted January 20, 2011 Share Posted January 20, 2011 Thanks John, i'll give them a go. The only thing that concerns me is that one of the beta testers for the 340 said on the avsim forum that the air file was correct, and he had x hundred hours in the 340 in real life, the 'floating' was a peculiarity of the real world aircraft and meant pilots had to know what they are doing to get her down. If this is so, does your mods take this (realistic) effect out? I'm a little confused. Link to comment Share on other sites More sharing options...
Ron Attwood Posted January 20, 2011 Share Posted January 20, 2011 Wot he said. ^^^ I'd be a bit worried about using a plane that was made to fly the way I wanted to, rather than the way it really does....If you catch my drift. Link to comment Share on other sites More sharing options...
rockliffe Posted January 20, 2011 Share Posted January 20, 2011 No, I absolutely agree Ron and following on from what John was saying in reference to the other forum, if it's true that the diffilcult landing parameters are realistic and part of the plane's aerodynamic characteristics then I will wholeheartedly accept them and learn to fly accordingly. My initial concern was that perhaps it was a bug or Carenado had missed this aspect of the plane's design and it was not true to the real world aircraft, however, I now know differently Link to comment Share on other sites More sharing options...

John Dow Posted January 20, 2011 Author Share Posted January 20, 2011 I understand the concerns about the reality of the landing and the statements that the aircraft floats a little in real life, I cannot argue other than to say there are at least three real world landing videos up at youtube and they all show a bit of power on and a reasonably quick touchdown, except one where the pilot kept the speed up quite noticeably on a long runway in Switzerland and held it off while reducing power slowly for about 5 seconds, and even he had some power on all the way until the wheels were well and truly planted. So I based my mods on real world examples. None of the landings on youtube show the kind of throttle closed behaviour that I found necessary to get the original release down on the mains without floating halfway down the runway. I believe my video closely resembles the approaches that are seen on youtube, without having the aircraft feel in any way like it's lacking lift in the approach.

Ron Attwood Posted January 20, 2011 Share Posted January 20, 2011 That's the very devil of it John, I agree with you too! You'd think that a professional outfit like Carenado would have that well and truly sussed eh? Seems so fundemental to me, it does or it doesn't kinda thing. Oi vey!

rockliffe Posted January 21, 2011 Share Posted January 21, 2011 So forgive me John, are we saying that the Carenado version does not resemble the real world aircraft and that your tweak brings it closer to the real thing? Link to comment Share on other sites More sharing options...
Ron Attwood Posted January 21, 2011 Share Posted January 21, 2011 No Howard, WE aren't saying that 'cos we know doodly squit. John is saying that. I've seen the videos he refers to and he's right. Confused? You wont be if you watch the next episode of "Carenado FDE" Doo do-do, do dooo* *Soap theme Link to comment Share on other sites More sharing options...

John Dow Posted January 22, 2011 Author Share Posted January 22, 2011 So forgive me John, are we saying that the Carenado version does not resemble the real world aircraft and that your tweak brings it closer to the real thing? Hi Howard Not exactly sure what you got out of my posts, but I believe if you go to Youtube and watch the three in-cockpit landings available you will see the rate at which it decelerates and gets down to the runway once over the threshold, with the engine sound showing there's still at least a little bit of power on until the wheels touch, and then try and duplicate those landings with the original Carenado files, and then try the same with mine, you should find that my files show landing behaviour considerable closer to the Youtube videos. Other than that I make no claim as to the accuracy or suitability of my mods! Link to comment Share on other sites More sharing options...
