Landing on runway 19 at KWYS Yellowstone Airport in the North American Rockwell OV-10 Bronco

Landing Score 90.42 %

Landing Summary

The aircraft approached runway 19 at KWYS Yellowstone Airport from the north-east on a heading of 206.0° while 2 NM out and 590 ft AGL, with ambient temperature 15 °C, wind 6 kt from 270°, a 5 kt cross-wind component and a 3 kt head-wind component.

At threshold the height was reported as good and the threshold speed was good at 88 kt. The aircraft crossed the touchdown zone 109 m beyond its start, touched down at 80 kt, and the touchdown rate was firm at minus 326 fpm. Runway touchdown alignment was very good.

Touchdown occurred with the stated speed and rate, confirming the firm contact and the very good alignment noted at the moment of wheel-strike.

The total landing distance was 700 m, representing 27 % of the 2 558 m runway, and the rollout alignment was slightly misaligned by 13.0 m from the centreline.

To improve the already strong score of 90.4 %, focus on reducing the 13.0 m rollout deviation and aim to touch down closer to the intended touchdown zone to keep the landing point within the optimal range.
