[Flightgear-devel] ASW20 panel

Hi Amos I don't know if you just want to use the T38 panel in the ASW20 or if you want to make a new panel using the T38 as a template. If it is the first then all you need to do is change the panel path in asw20-v1-nl-uiuc-set.xml to point at the T38 panel . If it is the second you need a

[Flightgear-devel] Gliding (Stall)

2003-08-01 Thread Christopher S Horler
I'm under the impression that an aircraft should be able to glide sensibly up to the stall and then you may encounter problems depending on the type of the wing, where the stall will occur on the wing and whether it will occur on both wings together. A prop driven a/c may give additional benefits

[Flightgear-devel] Opinion on different flight models

2003-08-01 Thread Martin Spott
Hello together, I'd like to comment on my experiences with different flight models - especially JSBSim and YASim. I'm using the C310 for the comparison. Take off with the default c310u3a-jsbsim, accelerate to somewhat over 120 knots and pull the elevator quick and firmly. Only a few seconds later

I experimented a little further. If I give the plane a stall by gradually reducing power and trying to keep my vsi 0, then release the stick and wait for some semblance of order to return. I notice that the stall develops on one wing and then eventually the plane will return to level, but it

The YAsim aircraft seem to have something slightly strange with the prop windmiling when then engine is not running. It's almost as if as you glide, you are winding up a big rubber band or something as the props windmill. Then eventually the props begin to generate so much negative thrust (drag)

From the description of the a/c oscillating, I'd guess you're using auto-pilot heading hold/wing-leveller. Try it without and you shouldn't get any oscillation. You can also get pitch oscillation or porpoising in some a/c at low speeds with AP alt hold too - that can be tamed by increasing

No I'm not using the Autopilot. I just don't think that the behaviour after the stall (when the plane begins to recover) is that realistic - this is when it oscillates On Fri, 2003-08-01 at 21:26, Lee Elliott wrote: From the description of the a/c oscillating, I'd guess you're using auto-pilot
