Question for pilots: vertical speed indicator

[Rockcliffe]

Does anyone with more knowledge than I care to comment on how realistic the VSI is in FS?
My understanding is that this instrument has a significant time lag before it shows the plane ascending or descending. In FS, however, it seems the VSI needle can swing to a 1000 fpm deflection when the altimeter has barely begun to move. Is this proper?
Thanks

The behavior of the VSI in FS seems fairly reasonable. The "lag" of the VSI in the real world is that it takes a moment to react, and it takes another bit to get to the actual indication, generally not catching up until the aircraft is in a steady state. But the lag is not all that long, either, just enough that you can't use it for absolute, immediate pitch control.

If you're in level flight with the VSI on zero, then begin a climb, the VSI will start to show a climb fairly quickly, but it will read considerably less than the climb rate until the climb rate has stabilized for a short time,when it finally catches up. Really, you're just dealing with a calibrated air leak.

Very interesting Larry,

Can always rely on you for a good, quick answer.

Thanks Larry.
