How do I reset the Attitude Indicator after a roll?

Postby xen_steda » Tue Jan 28, 2020 12:35 pm

So in my Warrior II I sometimes perform a complete roll and afterwards, the Attitude Indicator is all over the place and doesn't settle, is that something I can reset mid-air or is it messed up until I land? How can I reset it if possible? Thanks!

what kind of attitude indicator does the craft use?

is there a lock for it that you can apply for some time and then unlock? the idea here is to lock it and let it settle... then when unlocking, maybe it will swing to the proper orientation...

It's the traditional non glass style indicator. I will poke around and see if there is a lock somewhere near the indicator. Thanks!

the ones i'm familiar with in most craft have a knob you pull/push to lock or unlock the device... it may be there in the rendering but not even implemented... fingers crossed that it is...

i may take a look later if i get a chance... if the craft is available in the default FG hanger, that is...

It's the Piper PA 28-161 Warrior II thats in the Flightgear GUI hangar. Thanks for attempting to figure this out! Ill be able to try it later tonight in case you're unable to.

Don't let the FAA watch you rolling this plane...

When you fly relatively straight and level a few minutes afterwards, the attitude indicator will slowly realign itself as such a traditional mechanic instrument will do. Not designed for hitting certain pitch and roll limits.

I like discovering these gems, seeing someone has really taken care to model the real thing!

Ok so I should do some straight and level flying for a few minutes after my rolls? well, ok I guess I can do that for a LITTLE while xD Thanks for the information!

You should read the flight manual:

2.15 MANEUVER LIMITS

(a) Normal Ca tegory - All acrobatic maneuvers including spins prohibited.


So the proper modelling of this should probably be similar to the c172p, in that your wings fall off ;)

Well, to be honest, luckily it isn't as that would be highly unrealistic. An aircraft normally sustains far more than what is allowed.

It was a joke. I wonder if Piper actually knows what forces from which directions will snap the wings off. And how did we work that out for the c172p?

POH gives positive g-limit 3.8 normal and 4.4 utility. Should be possible in everything other than snap role.
Surprisingly negative g limit is given as zero. Strange. The wing will not be the limiting factor, as the underside will be able to sustain some compression stresses. Maybe due to fuel flow to engine?


There was one actual tragic accident with wings coming of. https://www.aopa.org/news-and-media/all-news/2019/september/06/report-cites-metal-fatigue-in-2018-piper-arrow-crash
Fatique due to high numbers of cycles flown.

i think you'd have to ask wlbragg about that... i think he was behind implementing it... if not, he would know who was ;)

Someone needs to review the numbers used if it is an issue. I don't recall exactly what they were but I know they were looked at, at least a glance. I would be surprised if some adjustments aren't warranted. Any changes based on real world figures would be gratefully accepted, for either aircraft.

So are you guys saying that I shouldn't be able to roll in the Warrior II?
