I got what I wanted. My altimeter needle runs noticeably faster than the variometer needle. That's the code I did it with:
Code
// vertical speed
<[vertical_speed_indicator][VerticalSpeedIndicator][]
<[string8][StaticPressure][PitotTube.StaticPressure]>
>
<[first_order_low_pass][SlowerVerticalSpeed][]
<[string8][Input][VerticalSpeedIndicator.VerticalSpeed]>
<[float64][TimeConstant][15.0]>
// <[string8][StaticPressure][0.0]>
>
<[output][VerticalSpeed][]
<[string8][Input][SlowerVerticalSpeed.Output]>
>

Note that the string with zeroing of the Value parameter is commented on. I needed the static pressure not to slow down in any way, the altimeter had to work fast.
And that was my last fix on the C172mod.tmd file. I made a few more editions in it, after which my Cessna in Aerofly began to fly almost the same way as the real one, which I had to pilot. She began to feel the full load of 3 passengers and fuel under the maximum permitted gross weight.
Thank you for your help.
