Fixing the bounce
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.

The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
One stabilised approach gate: five checks where the approach path is 500 ft above the runway. The 1,000 ft gate was not assessed, because the approach did not join final that far out.
Side view — the last 1,524 m of the approach.
Plan view — the first 1,524 m of the 2,037 m runway, to the same scale as the side view.
Touched down 526 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The flight began with a departure roll from runway 15 at NZKK Kerikeri Airport, a small airfield in Northland, New Zealand. The aircraft, a Piper PA-24-250 Comanche, accelerated down the 494-meter runway, covering 42% of its length, before lifting off into the air at a speed of 77 knots. The local weather conditions at the time were characterized by a temperature of 24 degrees Celsius and a gentle wind blowing at 4 knots from a direction of 238 degrees.
As the aircraft climbed away from the airport, it quickly gained altitude, rising from 1,316 feet above sea level to 3,074 feet in just 3 minutes, covering a distance of 5 nautical miles. This initial climb phase was followed by a level cruise, during which the aircraft maintained a steady altitude of 3,074 feet for 37 minutes, covering a distance of 75 nautical miles. The cruise phase took the aircraft west of Moerewa, another small town in Northland, before it began its descent towards the Auckland region.
The descent phase started 6 miles southeast of Leigh, a coastal town in the Auckland region, and involved a decrease in altitude from 4,018 feet to 3,350 feet in just 2 minutes, covering a distance of 5 nautical miles. Following this initial descent, the aircraft entered another level cruise phase, this time lasting 10 minutes and covering a distance of 18 nautical miles. This phase took the aircraft southeast of Leigh, before it began its final climb phase.
The final climb phase started 1 mile northeast of Murrays Bay, a suburb in the Auckland region, and involved a climb from 1,920 feet to 2,748 feet in just 2 minutes, covering a distance of 4 nautical miles. Following this climb, the aircraft entered its final approach phase, during which it descended from 2,748 feet to 1,121 feet above ground level, before touching down on runway 21 at NZWP RNZAF Base Auckland-Whenuapai.
The landing was characterized by a touchdown point that was 418 meters beyond the touchdown zone, indicating that the aircraft had overshot the intended landing spot. The touchdown speed was also too high at 84 knots, and the touchdown rate was fair at -236 feet per minute. However, the runway touchdown position was significantly misaligned by 18 meters from the centerline, and the runway rollout alignment was also misaligned by 22 meters from the centerline.
Following the landing, the aircraft taxied to the parking area, covering a distance of less than 1 nautical mile in less than 1 minute. The total flight distance was 113 nautical miles, and the flight used 44 kilograms of fuel. The aircraft's performance was affected by the local weather conditions, which were characterized by a temperature of 24 degrees Celsius and a gentle wind blowing at 4 knots from a direction of 239 degrees.
The Piper PA-24-250 Comanche aircraft successfully landed at NZWP RNZAF Base Auckland-Whenuapai, but the landing was not without its issues. The pilot achieved a final approach to runway 21 from the north east, heading 229.0° at 4 nautical miles and 1,121 feet above ground level. The aircraft touched down on the runway, but the touchdown point was 418 meters beyond the designated touchdown zone, indicating that the pilot may have misjudged the distance to the runway.
The touchdown speed of 67 knots was also too fast, which could have contributed to the aircraft's distance from the touchdown zone. The touchdown rate of -236 feet per minute was fair, but the high touchdown speed may have put additional stress on the aircraft's landing gear. Furthermore, the runway touchdown position was significantly misaligned by 18.0 meters from the centerline, which could have made the landing more challenging.
The local weather conditions were favorable, with a temperature of 24°C and a gentle headwind of 4 knots at 239°. The crosswind was negligible, with a speed of 0 knots. The total landing distance of 1,113 meters was 55% of the runway length, which is a relatively short distance. However, the runway rollout alignment was also misaligned by 22.0 meters from the centerline, which could have made it difficult for the pilot to maintain control of the aircraft during the rollout phase.
One of the key issues with this landing was the threshold speed, which was too high at 84 knots. This suggests that the pilot may have been unable to slow the aircraft down sufficiently before touching down, which could have contributed to the high touchdown speed and the distance from the touchdown zone. Overall, while the landing was successful, there were several areas for improvement, including the pilot's ability to judge the distance to the runway and to slow the aircraft down before touchdown.
