Static system froze during the previous night. The a/south indications were normal until altitude was gained. The V/south indicator showed no climb. The altitude showed field elevation. The a/south slowly unwound down to zero. Pushing the nose over did no good. Alternate static fixed problem and flight continued west/O further incidents. Nobody ever mentioned this possibility in any of my training. I have flown a lot of partial panel but never with the a/south, V/south and altitude missing. A ceiling a few ft lower would have killed us as we tried for airspeed.
Original NASA ASRS Text
Title: GA SMA LOSS OF CRITICAL INSTRUMENTS JUST AFTER TKOF.
Narrative: STATIC SYS FROZE DURING THE PREVIOUS NIGHT. THE A/S INDICATIONS WERE NORMAL UNTIL ALT WAS GAINED. THE V/S INDICATOR SHOWED NO CLB. THE ALT SHOWED FIELD ELEVATION. THE A/S SLOWLY UNWOUND DOWN TO ZERO. PUSHING THE NOSE OVER DID NO GOOD. ALTERNATE STATIC FIXED PROB AND FLT CONTINUED W/O FURTHER INCIDENTS. NOBODY EVER MENTIONED THIS POSSIBILITY IN ANY OF MY TRAINING. I HAVE FLOWN A LOT OF PARTIAL PANEL BUT NEVER WITH THE A/S, V/S AND ALT MISSING. A CEILING A FEW FT LOWER WOULD HAVE KILLED US AS WE TRIED FOR AIRSPD.
