That's all true. For instance, the playback.xml protocol should not bother to replay the state of the starter, since the process whereby the starter starts the engine is under control of the FDM, and the null FDM doesn't do this at all. It works better for the protocol to just replay the engine RPM. Similarly if you want the rate-of-turn needle to work, the protocol should replay /instrumentation/turn-indicator/indicated-turn-rate However ... that doesn't solve the mystery. I have already made those changes to my copy of playback.xml, and things are still messed up: -- The rate-of-turn needle flickers between correct (replayed) rate and zero. (This may be related to the longstanding flicker/shudder problems with external views during playback.) -- Replaying /engines/engine[0]/rpm has no effect ... even though setting the same property via the property browser has the expected effect: causing the engine to spin at the specified rate. -- As previously mentioned, the LOC and GS needles are frozen, even though the properties used by the animations in vor.xml are being set. It's one thing to say more properties need to be set ... but when the properties are being set and the instruments still don't work, I have no idea how to get them to work. If the FDM should do more ... what more should it do? ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
