What was found
A FLIGHT TEST WAS BEING CONDUCTED ON 07/30/07 ON A REWORKED THERMAL SYSTEMS (KATS) EVADE SYSTEM, WHEN THE SYSTEM WENT UNSTABLE CAUSING THE ALTERNATOR TO GO OFF LINE. THE TECHNICIAN MONITORING THE SYSTEM ON A DIAGNOSTIC LAPTOP COMPUTER ANNOUNCED TO THE PILOT THAT THE SYSTEM WAS FAILED BUT THE PILOT DID NOT HAVE A "FAILED" ANNUNCIATION ON THE INSTRUMENT PANEL. KATS CONFIRMED THAT THERE WAS A PROBLEM WITH THE FAULT DETECTION SOFTWARE THAT WOULD ALLOW THIS UNDER VERY SPECIFIC CONDITIONS. KATS STATED THAT THEY DO NOT BELIEVE THIS TO BE A SERIOUS SITUATION SINCE THE SYSTEM IS CERTIFIED INADVERTENT ICING ONLY.
