Hi guys
While flying this morning my Enigma nearly gave me a heart attack. I was at 6500ft when suddenly the VSI indicated +2350 and in one second I found myself at 23700 ft! some record Ill say

when on finals the negative was happening, descending at more than 2000ft per minute is not for the feint at heart

Has anybody ever experienced this? the airspeed seems to be ok in fact the rest of the readings were fine as I have steam to verify them. It was just the ALT and VSI that went crazy.
Help
Cheers
