Hi. I'm doing a project where I'm developing a hover assist gauge. I do know that there are 1 or 2 of these floating around, but I'm doing this for my own sake of learning. Since I am new to FSX development I'm fussing over an issue I have. I want to show current drift (implemented) and also Yoke position (implemented) but I also want to show a suggested counteraction to bring you to a steady hover. (Chase the ball type representation) The issue I'm having is that a centered yoke position will not mean that you stay in a static hover, if i just give a division of the inverted current drift, in the big picture that'd bring you closer to a hover, but at a close to hover it wouldn't give the correct info to "stay on the ball" if you know what i mean Eg.. at a still hover it'd say keep the yoke dead centered since there is no drift. Whereas in alot of helicopters I've tried in FSX a centered yoke will cause the helicopter to start flying forward and to stay in one position you actually have to angle the yoke back slightly. What I'm wondering is are there any FSX variables that could help me predict this and take it into account in my display or is that something that I'd have to model for each helicopter. Since there are some autopilot gauges out there I'm figuring that it can be solved.. I'm just curious if anyone can point me in the direction as to how. Ty in advance =) Ofc the results will be freeware and accessible to anyone who wants them when they are done.
