Landing on runway 31 at KPIR Pierre Regional Airport in the F-35A Lightning II

Landing Score 80.53 %

Landing Summary

The F-35A Lightning II aircraft successfully landed on runway 31 at KPIR Pierre Regional Airport, but with some notable deviations from optimal landing procedures. The aircraft approached the runway from the southeast, heading 321.0° at 4 nautical miles and 1,055 feet above ground level (agl). The landing was executed on a runway with a length of 2,097 meters, which provided sufficient space for the aircraft to touch down safely.

However, the threshold speed was excessively high at 197 kt, indicating that the pilot may have been unable to slow down the aircraft sufficiently before reaching the runway threshold. This could be attributed to various factors, including the aircraft's speed at the start of the final approach or the pilot's decision-making during the approach. On the other hand, the threshold speed was a little below target at 132 kt during the second landing, suggesting that the pilot was able to adjust their approach to achieve a more optimal speed.

The touchdown distance of 106 meters was considered good, and the touchdown speed of 126 kt was also within acceptable limits. However, the touchdown rate of -682 feet per minute (fpm) was heavy, indicating that the aircraft may have touched down with a higher rate of descent than desired. This could have resulted in a bumpy ride for the pilot and potentially caused damage to the aircraft.

One of the most significant deviations from optimal landing procedures was the runway touchdown position, which was significantly misaligned by 15.4 meters from the centerline. This could have resulted in a longer rollout distance and increased the risk of veering off the runway. The runway rollout alignment was also significantly misaligned by 44.5 meters from the centerline, further exacerbating the issue.

The local weather conditions at the time of the landing were characterized by a temperature of 19°C and a wind speed of 22 kt at 41°. The crosswind component was 22 kt, while the headwind component was 3 kt. These conditions may have contributed to the difficulties experienced by the pilot during the landing.

Overall, while the F-35A Lightning II aircraft successfully landed on runway 31 at KPIR Pierre Regional Airport, the landing was not without its challenges. The pilot's ability to adjust their approach and landing procedures to compensate for the adverse weather conditions and the aircraft's performance was crucial in ensuring a safe landing. However, the deviations from optimal landing procedures highlighted in this report suggest that further training and practice may be necessary to improve the pilot's skills and the aircraft's performance.
