Re: [Flightgear-devel] Fuel Weight dialog changes docs
This feature seems to be pretty underutilized, even for a lot of the aircraft for which it was intended. So in case anyone isn't aware of how it works, here are some docs: The FW subsystem is entirely property driven. In your -set.xml file you add a bunch of /sim/weight[n] definitions like: weight n=0 nameLeft Rear Passenger/name weight-lb0/weight-lb !-- initial/runtime value -- max-lb300/max-lb min-lb60/min-lb !-- optional, defaults to zero -- /weight This will get you a slider labeled Left Rear Passenger that you can tweak at runtime from the dialog. The FDM configuration would obviously read /sim/weight[0]/weight-lb to get the weight at runtime. ... Hmm. I'm not sure how this interacts with JSBSim weight and balance properties. I just got back from Keystone (AIAA Modeling and Simulation Conference) and need to take a good look at this more closely, but does anyone know how this interacts with all FDMs?

The dialog is currently disabled for JSBSim, but the interface is really very simple. The weight interface is trivial: if you can import a point mass into the FDM from a property named in configuration file (specifically /sim/weight[n]/weight-lb at the moment) then you can use this without change. The fuel stuff is only a little more complicated; the docs are at the top of Nasal/fuel.nas. But the essence is that the tank capacity and current fill need to be settable from script space via the /consumables/fuel/tank[n]/... property trees, and the engines need to export their consumption (currently YASim sets a fuel-consumed accumulator value, but we could make this work with a flow rate with some extra nasal).

Andy Yeah, this sounds do-able. If someone else doesn't pick this up, I'll put this on my list. Thanks. Jon - Using Tomcat but need to do more? Need to support web services, security?
