Top opportunity

Fixing the bounce

Arrival Touchdown

Fast at the threshold, normal flare, and the runway seems to refuse the aircraft. The instinctive fix - pushing it on - causes the next one. A fast aircraft forced onto the runway touches nosewheel-first or nearly so. The tell is a touchdown that feels soft followed by a bounce that steepens. Pilots fix the bounce recovery; the cause was the 10 knots at the threshold.

Flight narrative

The flight began with a departure roll from runway 26 at LSGK Saanen Airfield, where the aircraft, a Piper PA-24-250 Comanche, accelerated down the 351-meter runway, using 45% of its length. The liftoff speed was achieved at 74 knots, and the aircraft lifted off into the local weather conditions, which included a temperature of 15°C and a wind of 4 knots at 359°.

As the aircraft climbed away from the airfield, it began its enroute climb, which started overhead Saanen in the Canton de Berne, Switzerland. The climb was steep, with the aircraft rising from 3,594 feet above sea level to 5,005 feet in just 2 minutes, covering a distance of 2 nautical miles. This rapid ascent was followed by a brief enroute level cruise, which lasted for 2 minutes and covered a further 3 nautical miles.

The enroute descent began 2 miles southwest of Zweisimmen in the Canton de Berne, Switzerland, and was a more gradual process, with the aircraft descending from 5,378 feet to 3,656 feet in 3 minutes, covering a distance of 3 nautical miles. The final approach to runway 14 at LSTS Sankt Stephan Airfield was made from the northwest, with the aircraft heading 133.0° at 1 nautical mile and 337 feet above ground level.

The landing itself was not without issues, as the touchdown speed was excessively fast at 87 knots, and the touchdown rate was very hard at -520 feet per minute. The touchdown point was also very long, using more than 50% of the available runway, and the runway touchdown position was misaligned by 11.4 meters from the centerline. The local weather conditions at the time of landing were a temperature of 14°C and a wind of 6 knots at 359°, with a crosswind of 4 knots and a tailwind of 4 knots.

The total landing distance was 808 meters, which was 88% of the runway length. The runway rollout alignment was also slightly misaligned, by 12.2 meters from the centerline. Despite these issues, the total flight distance was only 9 nautical miles, and the aircraft used a relatively small amount of fuel, just 6 kilograms.

Landing Summary

The Piper PA-24-250 Comanche aircraft has successfully landed at LSTS Sankt Stephan Airfield, but the landing was not without its issues. The final approach was conducted from the north-west, heading 133.0° at 1 nautical mile and 337 feet above ground level (agl). The aircraft touched down on runway 14, which has a length of 917 meters.

Upon reviewing the landing, it appears that the threshold height was good, but the threshold speed was excessively high at 88 knots. This indicates that the pilot may have been unable to slow the aircraft down sufficiently before reaching the runway threshold. As a result, the touchdown point was very long, using more than 50% of the available runway. This is a concern, as it leaves little room for error in case of an unexpected stop or other issues.

The touchdown speed of 87 knots was also excessively fast, which contributed to a very hard touchdown rate of -520 feet per minute (fpm). This is a significant impact, which could potentially cause damage to the aircraft or pose a risk to the occupants. Furthermore, the runway touchdown position was misaligned by 11.4 meters from the centreline, which could have contributed to the difficulties in slowing the aircraft down.

The local weather conditions at the time of the landing were relatively calm, with a temperature of 14°C and winds of 6 knots from 359°. The crosswind and tailwind components were both 4 knots, which is relatively minimal. Despite these favorable conditions, the pilot was still unable to achieve a smooth and controlled landing.

The total landing distance was 808 meters, which is 88% of the available runway. This is a significant portion of the runway, and it suggests that the pilot may have been unable to slow the aircraft down sufficiently before reaching the end of the runway. The runway rollout alignment was also slightly misaligned by 12.2 meters from the centreline, which could have contributed to the difficulties in controlling the aircraft during the landing.

Overall, while the aircraft was able to land safely, the landing was not without its issues. The excessively high threshold speed, fast touchdown speed, and hard touchdown rate all contributed to a difficult and potentially hazardous landing. The pilot will need to work on improving their landing technique and slowing the aircraft down more effectively in order to achieve a smoother and more controlled landing.
