Limit roll and pitch rotation

[csw123]

Hi everyone! :)

I'm trying to build some simulator and one of the demands is that my plane rotation and pitch cannot pass the 30 degrees (from the center ofc), how can I limit the plane rotation in order to achieve that?

I hope i explained it good enough..:confused:

Thank you :)

Thank you so much for your quick answer!

Your answer is for autopilot, how can i do that for manual also?

Thx again

Of course not. MAN... is unrestricted of his own stupidities and can kill his own self any time accordingly.

Build a simulator? Explain more.

[csw123]

ok ill need to explain it better :$

I have something similar to this pic

and it can't roll/pitch(mechanically) over 30 degrees , and at FSX it obviously can

I want to limit it at FSX as well, so the aircraft won't be able to roll/pitch more than 30 degrees.

better? :confused:

Thx!

I can only come up with putting some kind of mechanical limiters on your joystick controller to limit the movement side to side and front to back. After seeing your contraption..….I advise keeping a barfbucket handy!

Sorry Mr Z, I don't think that will help. Limiting joystick movement will only limit the RATE at which the plane pitches and rolls, not the amount. Great idea on the sick sack, though.

You are probably right! For a pilot to keep a 30 degree pitch/roll rate, like the A/P does, wouldn't he be constantly making adjustments to the stick? My head hurts just thinking about it! Where's that barfbucket??

[mabe5454]

MZ why not place mechanical limits to the contraction instead? 50 degree on the roll either side and pitch up and down, that should be enough excitement. OP should make sure the insurance cover is up to date and includes experimental contractions.

Thank everyone for your answers :)

So i guess its complicated that I thought..

Any chance that FSUIPC or something similar can help?

Thanks again

Just think that if you want to limit the input to your actuator, then you are complicating the system as you will need feedback position sensors. Mechanical stops by far the easiest & possibly safest, and if you have say a microswitch, that can stop the input to the actuator. It might be possible to write an xml input, similar to that which I created for my Meteor U16, but that used the autopilot, but as I said it will need feedback info.
