No, if you read the report, he was on final and, for whatever reason, instead of continuing the landing procedure he decided to change the aircraft mode to vertical landing and this caused the helmet to glitch.
- db48x 2y agoThe redacted version of the report does not state that there was any causal link between switching to SVTOL and the failure of the HMD. Only that the HMD happened to fail shortly after he switched modes: 95. Approaching the final approach fix, the MFL made the radio call to convert the flight to Mode 4 (STOVL) and slow the flight to 150 knots in preparation for the 100-knot slow landing. This was the last radio call Swede 12 heard from Swede 11. [Encl (17), (19)] 98. MP reported his HMD flickered shortly after converting. Near simultaneously, a momentary caution displayed in his HMD that he perceived to be engine-related and then the HMD flickered out. While MP considered missed approach options, the HMD came back. [Encl (17)] And from the evaluation: 19. Primary factors contributing to the mishap can be traced back to event that occurred at 13:32:05. This event induced failures of both primary radios, the TACAN, and the ILS. [FF 100, 101, 126-129] 20. Additionally, it is probable that the HMD and PCDs were not operational for at least three distinct periods. [FF 98, 103, 104, 106, 114, 132-136, 141]
