Re: Trying to simulate instrument errors in a VSI
Yeah. IVSI Have INSTANTANEOUS written on the face of the Gauge somewhere

Re: Trying to simulate instrument errors in a VSI
Good proof of concept, but I am afraid that’s a bit of a hair pull. Most if not all of the modern aircrafts are equipped with IVSI (instantaneous vertical speed indicator), built to counteract the effect you’re trying to implement by using counterweights and small pistons. https://www.mcico.com/reso...

Re: Source for low profile rotary encoder and housing
Flat encoders which were used mainly in old mouses with ball are a good solution. Only 1.2 mm width you have to add a shaft though and there’s no pushbutton

Re: VSI and altitude
The calibration hole is mainly here to introduce a certain lag in the indication so it’s more realistic, instead of showing an instant rate of climb/descent where the needle literally jumps to the max ROC/ROD. A slight delay if a couple of seconds is introduced.

Re: VSI and altitude
I “think” you are probably overthinking this. In the standard atmosphere model the pressure decreases “almost” linearly with altitude since density is derived from temperature that changes linearly with altitude. The real formula is here: http://fisicaatmo.at.fcen.uba.ar/practicas/ISAweb.pdf Integra...

Re: ((autopilot_state >> 4) & 1 == 1) )
Interesting question.
Not sure if in Lua true is equal to 1 and false equal to 0 as in other languages. Not a Lua specialist to be honest, just using the normal stuff, never used bitwise operations.
Take care my friend!

Re: ((autopilot_state >> 4) & 1 == 1) )
Hi guys if ((autopilot_state >> 4) & 1 == 1 basically is shifting right the bits of autopilot_state so by shifting 4 places and then 'anding' with 1 means we are looking specifically at the bit 4 in autopilot_state. the & 1 == 1 could simply be & 1 as far as I can see as this is operati...

Re: ((autopilot_state >> 4) & 1 == 1) )
1==1 is always true AFAIK. I don’t know what’s the point with this part of the code. And without the surrounding code it is difficult to understand what it is doing. Where autopilot_state gets its value from? Is it for MSFS? Which addon? The best is to tell which autopilot instrument the code extrac...

Re: VSI and altitude
Hi. What you described is the principle for an altimeter. The aneroid capsule is sealed and submitted to the ambient static pressure taken from the static port. Less ambient pressure outside the capsule, inflates the capsule and moves the needle through a set of reduction gear. A VSI in its principl...
