Departure Roll

A small uncorrected heading error at 40 knots becomes a metre of offset per second by 100 knots, noticed only at rotation, producing a crabbed liftoff. Root cause is nearly always eyes on the tape instead of the far end of the runway. Small heading changes displace a distant point visibly long before the nearby centreline stripes look wrong.

Landing Summary

The OV-10 Bronco aircraft successfully landed at runway 17 of the 8U8 Townsend airport, achieving a score of 94.1%. The final approach was initiated from the north, heading 178.0° at an altitude of 286 feet above ground level (agl) and 0 nautical miles from the runway. The aircraft maintained a steady course, eventually touching down on the runway.

The landing performance was satisfactory, with the threshold height being above the target at 62 feet agl. However, the threshold speed was significantly higher than the target at 106 knots, indicating that the pilot may have been able to reduce the speed before touchdown. The touchdown distance of 404 meters was considered good, indicating that the aircraft was able to maintain control and stability during the landing.

The touchdown speed of 92 knots was slightly faster than the target, which may have resulted in a slightly higher touchdown rate of -276 feet per minute (fpm). Despite this, the runway touchdown alignment was very good, indicating that the aircraft was properly aligned with the runway centerline.

The local weather conditions at the time of the landing were favorable, with a temperature of 15°C and a wind speed of 3 knots from 269°. The crosswind component was minimal at 3 knots, while the headwind component was zero. These conditions likely contributed to the successful landing.

The total landing distance of 876 meters was 72% of the runway length, indicating that the aircraft was able to stop within a reasonable distance. The runway rollout alignment was also very good, suggesting that the pilot maintained control and stability during the rollout phase. Overall, the landing was considered successful, with the OV-10 Bronco aircraft demonstrating good performance and control.
