FSX heading off

[Guest nhraracer90]

You should know that in forums that require people to reply it is polite to consider the level of imposition on any request. What you have effectively said is that you can't be bothered, but expect everyone else to...? Not good thinking. :( What I say is that I have answered your question in a form which will probably also answer many more of your questions, saving you from needing to impose on others. It would certainly have answered your follow-on question, so it is obvious that you are not looking for a hand up, you expect a hand out. You need to re-think that rationale.

What I have said is I can't be bothered, but expect everyone else to? I asked a simple question at first, then a simple question after that. (You missed the clue, ITS ALL IN THE LEARNING CENTER) does not seem to be a polite response to my simple question now does it? Even after I got that good explanation from pontiuspilotus. I'm the one being mean here? Right.

Most here are happy to assist you, while at the same time pointing you to additional sources of pertinent information. It's the best of both worlds, so don't let some discourage you from asking, but you should use all available recources provided.

Yes I know I should use all resources provided, but the resources do not have to be given his way. I also like how I am getting heat on here for responding to the way someone attempted to answer my question, but not the response that was given.

EVERYBODY just calm down. You are free to ask whatever you want in these forums so long as you abide by the AVSIM terms of use. It is not an inconvenience for anyone to answer a question. If you don't want to answer, you don't have to.

getting back to the main question, if the aircraft has a slaved gyro system, should it be assumed that there is 0 drift? (IRL and I assume FSX will always give 0 drift?) I guess in some cases there can be a slave meter to show the difference in heading, though I've never seen this in an FS panel.scott s..

Don't think slaved gyros are natively supported by FSX - it's a bit `on/off` simplistic in that regard, but that's not to say there aren't addons that mimic the effect - but then the simple solution is simply to turn off the gyro drift in the options menu, and it doesn't get much simpler than that - other than to make regular use of the `D` key if you keep it on!

Thanks, I note from aircraft.cfg:direction_indicator.0 to direction_indicator.n One or two codes. If the indicator is type 4, then there must be two entries here (the indicator, and the indicator to which this one is slaved). The indicator codes are:0 = None1 = Vacuum gyro2 = Electric gyro3 = Electro-mag slaved compass4 = Slaved to another indicator scott s..

But is there any effective difference? Certainly none I can see with the default aircraft and their gauges.To be honest I gave up on this after FSX was released and they clearly didn't fix what was already in FS9, so I just switch gyro drift off and forget about it. It's not as if the declination is accurate anyway. I suppose one might amend magdev .bgl using Herve Sors tools but you still end up with a static rather than dynamic effect, with no variation caused in-cockpit from use of electrical items.

What you're describing in-cockpit is deviation, not variation. I don't list that among FSX' shortcomings...that'd be something you'd have to program into the panel gauges anyway, as each acft is different. It wouldn't be that hard to do, but you'd have to supply a compass card on the panel. Odd that nobody seems to have done this on some of the smaller GA acft.Remember, True Virgins Make Dull Company:True hdg -> plus Variation -> Mag hdg -> plus Deviation -> Compass hdgOn the other hand, the presence of GPS-derived heading displays in almost all categories of acft has made compass deviation and gyro drift something less of an issue than it once was.RegardsBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO

I was aware of the difference but one without the other renders the usefulness of the other somewhat moot. And the variation is subject to, er, variation over time as the Earths magnetic field constantly fluxes, so this moves it well outside the realm of the `easy gauge fix` into some quite complicated programming, and with undesirable effects on anything in the sim that is based on the initial improper constant. And it this total `improperness` that gives rise to the best solution which is to switch off gyro drift!GPS has all but rendered this proper pilotage irrelevant but, as my old flight instructor warned me once, while stressing the importance of aligning even in the digital age: "Engines can stop. Batteries can fail. Electricity can be interfered with. Magnetism makes the World go round....When there's no motor, no juice and no power only a compass points the way to the nearest airfield!" :(
