Landing on runway 36 at RCKU Chiayi Airport in the Cessna Citation CJ4
Landing Score 93.85 %
Landing Summary

The Cessna CJ4 Citation aircraft successfully landed at RCKU Chiayi Airport, achieving a score of 93.8%. The final approach to runway 36 was initiated from the south, heading 360.0° at a distance of 4 nautical miles and an altitude of 1,268 feet above ground level (agl). The aircraft's approach was characterized by a good threshold height, indicating a stable and controlled descent.

Upon touchdown, the aircraft's threshold speed was slightly below the target speed of 102 knots, registering at 101 knots. This minor deviation from the target speed did not significantly impact the overall performance of the landing. The touchdown distance of 438 meters was also deemed good, indicating a controlled and smooth touchdown. The touchdown speed of 87 knots was within the acceptable range, further contributing to the success of the landing.

One notable aspect of the landing was the excellent touchdown rate of -89 feet per minute (fpm). This rate suggests that the aircraft touched down with minimal deceleration, indicating a well-executed landing. However, the runway touchdown position was misaligned by 11.2 meters from the centerline, which may have been due to factors such as wind or pilot error.

The local weather conditions at the time of the landing were favorable, with a temperature of 18°C and a wind speed of 11 knots at 9°. The crosswind component was minimal at 2 knots, while the headwind component was 11 knots, which may have contributed to the slight misalignment of the runway touchdown position. The total landing distance of 1,113 meters was 36% of the runway length, indicating a relatively short landing distance.

During the rollout phase, the aircraft's alignment was slightly misaligned by 11.2 meters from the centerline, which may have been due to the same factors that contributed to the initial misalignment. Overall, the Cessna CJ4 Citation aircraft demonstrated a high level of proficiency in landing at RCKU Chiayi Airport, with a score of 93.8% reflecting its successful performance.
