The Cessna 208B touched down on runway 27 at KMMH Mammoth Yosemite Airport with a satisfactory approach quality, demonstrating good control and precision throughout the descent. The aircraft descended from 3 nm and 1,298 ft above ground level (agl) to a good threshold height, setting up for a smooth touchdown. The threshold speed was slightly below the target at 59 kt, but still within acceptable limits.
As the aircraft made contact with the runway, it exhibited good touchdown characteristics, with a speed of 46 kt and a touchdown rate of -22 fpm, indicating a controlled and stable descent. The touchdown distance of 975 ft was also within the desired range. However, the runway touchdown position was slightly misaligned by 19 ft from the centreline, which may require some adjustment in the approach and landing technique.
The aircraft's rollout was well-managed, with very good alignment on the runway. The total landing distance of 1,738 ft, which accounted for 25% of the runway length, was within acceptable limits. Overall, the landing was considered satisfactory, with a score of 97.3%. The local weather conditions, with a temperature of 59 °F and a light wind of 2 kt at 49 °, contributed to a relatively straightforward landing.
