Brings back memories of the RFDS King Air crash at YMTG years ago when they were going to pick up a young lad to take interstate for a transplant.
The pilot of that flight was very experienced. Dark night final approach in mist. Pilot reported visual but aircraft crashed on final at 3nm. Witness saw the aircraft landing lights on final. ATSB unable to determine cause of that accident. After the ATSB report was published it was revealed that the T-VASIS was previously known to give erroneous indications in similar weather conditions.
