Unrealistic needle wobble

[julpeuz]

Hi guys,

I find the needle wobbling on the MAP, altimeter and VSI to be pretty unrealistic and artificial. Especially on pneumatic instruments, which by definition are dampened by the length of the pneumatic lines. 
 

See here, I cannot see a single needle wobbling like that :

I know they’re modern instruments, but the physic hasn’t changed. 
 

What are your thoughts ?

I also find the wobbling a bit annoying, but probably in the video there are modern avionic modules installed in the cockpit, whereas in the simulation the goal is to recreate period accurate avionics... I’m not sure what the mechanics behind that wobbling are, maybe it should sync with the dashboard vibrations or other forces…

However, your reference video is not particularly suitable, as modern instruments are installed there...

The pitot static associated needles definitely should not wobble, with the exception of airspeed, which would be associated with transient airspeed changes, or turbulence, not cockpit vibration.  Manifold pressure too.  Caught my eye as well.

I could not agree more with julpeuz! I've been flying IRL since 1973 and have accumulated over 11,000 hours, mostly in helicopters and have never witnessed that kind of defect in those type instruments. As opposed to Havebug, I find it very annoying, especially given that there doesn't seem to be any good reasoning behind it.

I’m also a plane pilot IRL and although not as experienced as you, never seen that before as well. Maybe on the RPM gauge in my PA38 days, but never in a pneumatic instrument. And seemingly the airspeed wobbles is not associated with transient airspeed changes.

So I haven’t flown the Corsair, but I’ve ran it, taxiid it, and I fly a number of other warbirds in real life.

This needle wobble drove me nuts when I saw it! I have never seen manifold pressure, altimeter or VSI bouncing in flight. Other gauges might wobble, notably RPM, but it’s minor. So I agree with you 100% that the wobble is way excessive.

Thanks for your feedback

Also fly planes IRL , only RPM could be bouncing, I have seen than a few times, the rest don't.

Needle wobble is very annoying distracting. A bit  overdone. How do you hold 38in of manifold pressure?  34-42 on the bouncy gauge is close enough

I figured that it was my knees shaking causing those needles to vibrate.

We'll look into this.  It was added to give the cockpit a bit more life.  

We may add a slider in the special options to allow users to set their preference.

It’s a great touch! Just a little much, and the wrong instruments from what I’ve seen flying warbirds in real life.

Agreed. If you wanna bring life to this bird, may I suggest heavy grey smoke on startup and low frequency vibrations of the whole cockpit for startup and cutoff.

I think the majority would prefer historically accurate as a baseline, in all aspects.  Thanks.

It’s a different thing, cockpit frame might shake, things in the cockpit might shake, like aiming sight, but never needles in the altimeter or VSI, as others mentioned maybe RPM but not the rest.

To make cockpit more alive shake the cockpit not the needles, it’s unrealistic and indeed annoying.

In a damaged engine the Manifold Pressure gauge could bounce some, but damaged engine, not normal.

Couldn’t have said it better.

Fuel pressure needle can wobble a bit too

I've flown a dozen gliders... I've never seen pneumatic instruments ASI, VSI, Altimeter be anything but smooth with one educational and a little amusing exception (*1).

Common sense tells me if some design error made pneumatic instruments twitchy on the prototype, this error wouldn't be let into mass production. Engine instruments are a different category, maybe those could wobble, I wouldn't know,  but developer should not add things without evidence to make things "livelier".

I would not want all wobbly instruments on the same "slider". It would be annoying since the pneumatic instruments doesn't wobble AFAIK. Unless they actually have specific information that they do, which I doubt.

Googling wobble and pneumatic instruments, bunch of weekend private plane flyers don't expect wobble in Cessna and Pipers, they think it's broken. One suggestion is unplugging static air intake on back of instruments to distinguish if it's instrument itself or tubing.

*1) Pulling the stick hard (to hard) while turning the Schleicher ASK 21 , the static air intake comes into turbulence, making the ASI, VSI and Altimeter twitch rapidly and synchronously. Makes sense as all three connects to static air input.

How VSI works in two minutes.
