The DHC-4 Caribou aircraft successfully landed at LSTA Raron Airfield, achieving a score of 92.4%. The final approach to runway 10 was conducted from the west, with a heading of 90.0° at a distance of 4 nautical miles and an altitude of 1,697 feet above ground level.
The aircraft touched down on the runway with a good threshold height, and the threshold speed of 59 knots was well below the target speed, indicating a safe approach. However, pilots were advised to exercise caution to avoid stalling the aircraft. The touchdown distance of 84 meters was satisfactory, and the touchdown speed of 57 knots was also within acceptable limits.
The touchdown rate of -203 feet per minute was considered fair, suggesting that the aircraft could have been brought down more smoothly. Nevertheless, the runway touchdown alignment was perfect, indicating that the aircraft was properly aligned with the runway.
The local weather conditions at the time of landing were characterized by a temperature of -3°C and a wind speed of 0 knots from 231°. There was no crosswind or headwind, which made the landing conditions ideal.
The total landing distance of 297 meters was 51% of the runway length, indicating that the aircraft was able to stop within a reasonable distance. The runway rollout alignment was also perfect, suggesting that the aircraft was properly aligned with the runway during the rollout phase.
