Eine Antwort aus dem COPA-Forum:

I don’t trust the STEC after it tried to kill me on a few occasions and would never ever trust it in IMC close to the ground. IMO the fact that you can have it capture current altitude by pressing the ALT button a microsecond before VS is criminally dangerous. At least the DFC90 is better in that sense.

Aber was wissen die blöden Amis schon vom Fliegen!
