Re: [Flightgear-devel] Spitfire - new release
OK, Melchior helped to debug this via chat while I was working on cell phone UI bugs at work. :) It turns out to have been a pair of typos in fuel.nas that were causing all the problems. What I *read* wasn't what the code was actually doing, which explains all the confusion. This one, though, isn't fixed: > 3. When a tank is empty, the tank is de-selected by fuel.nas. Thus > the position of the fuel cock levers on the Spitfire panel do not > necessarily reflect the state of the tank. This is really a metaphor collision. The notion of a tank "selected" as used by the fuel code and FDM isn't quite the same as that of position of the switch in the cockpit (the magneto switches have traditionally had the same issue). It might be a better idea to define a different property to drive the fuel cock animation, and use a Nasal binding to synchronize this with the tank selected property only when it changes (basically: make the fuel cocks "output only" devices).

That's bad news not only for the flying community but for the Ah...oh. H. What is the "AIP"? I hadn't read "government" into that first posting at all, but maybe there was a typo. If it is the RAAF or Aussie government in some form, this could be a serious problem for information on the web, that goes a bit beyond this one data set. Uggh...greed.

The patch to fuel.nas changes the intended behavior, for no reason that I can identify. Describe only the bug please, not the changes.

[Flightgear-devel] tough week
Hey guys, For all of you who have emailed me and still haven't received a response, I just wanted to let you know that I haven't forgotten about your messages. They are still in my pending/inbox. I was out of town over the weekend and this has been a tougher than average week here. My wife started back to work full time and the kids started up in day care full time so we have massive scheduling adjustments going on here, and mornings/evenings have become way more hectic. Also I have a huge thing going here at my day job with a tight deadline (end of next week) so it's tough for me to sneak a few background few cpu cycles during the day for FG stuff. And on top of all that, my big dog has become very un-well and we aren't sure yet what's going on. We are starting to get pretty worried about him. I know that several people have emailed me with important FG stuff and it's all still in my pending inbox, but other than lurking and maybe kicking out a quick message here or there relating to things that are quick/easy, I'm probably not going to be able to deal much with FlightGear stuff this week ... and maybe not next week either the way things are going ...

[Flightgear-devel] Spitfire - new release
Eric has kindly uploaded the most recent release of the Spitfire model to cvs. If you haven't already noticed, this release adds a fuel system with Upper and Lower tanks (which are interconnected), priming pump, fuel cocks, and a fuel gauge. Unfortunately, there are three problems with this release: 1. With both fuel cocks open, when the fuel in the Upper tank runs out, the engine stops, despite the lower tank having fuel available and being selected. This is, I believe, due to a bug at line 67 of the script ~/data/nasal/fuel.nas which improperly sets the tank property "kill-when-empty". This problem is not unique to the Spitfire model, but affects all YASim models. This can readily be demonstrated by taking any such model, and using the drop-down dialog to reduce the fuel in one tank. With the engine running you can watch the fuel in that tank run out and the engine stop. 2. If both fuel cocks are moved to the "off" position and back to the "on" position the engine will not start or restart, even if fuel is available in all tanks. The Simulator has to be restarted to overcome this problem. This problem is caused by the logic of fuel.nas, and is not a bug. 3. When a tank is empty, the tank is de-selected by fuel.nas. Thus the position of the fuel cock levers on the Spitfire panel do not necessarily reflect the state of the tank. Again, this is not a bug, but a consequence of the logic of fuel.nas and of the operation of the levers. Solutions: 1. Short term. A. Use only the Lower Tank. Although this is contrary to the POH, it works perfectly well. B. Avoid setting both fuel cocks to "off". C. Move the fuel cocks through their full range to realign them 2. Medium Term. I attach a script - fuel-new.nas which is a minor modification of fuel.nas that works around the bug at line 67 and modifies the logic so that problems 1 & 2 above are corrected. Problem 3 remains. You can use this script to replace fuel.nas if you want, or perhaps, if accepted, it could be uploaded to cvs as a temporary replacement for fuel.nas. I believe that it will work for all YASim models, and has no adverse effects on non-YASIM models: don't throw fuel.nas away just in case (But don't leave both in ~/data/nasal). 3. Longer term. It would be a better solution if the problem with line 67 could be investigated so that it can be made to work correctly. Similarly, the logic of fuel.nas could be reviewed to correct problems 2 & 3 above. I am well aware that Andy is very busy right now, but perhaps he could spare some time? On the other hand, this is not a show-stopper. Melchior Franz has been most helpful in helping me with testing the problems and the replacement script. I think that he may be in a position to confirm both my findings and the efficacy of the new script.
