Reduce your height at the threshold
Even a modest height error carries straight through to the touchdown. Geometry alone says that crossing the threshold 10 feet high on a 3° path moves your touchdown roughly 190 feet further down the runway before the flare adds anything.

The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
One stabilised approach gate for a circuit: five checks where the approach path is 500 ft above the runway. The 1,000 ft gate is an instrument-approach check and does not apply.

Side view — the last 1,524 m of the approach.
Plan view — the first 1,524 m of the 2,737 m runway, to the same scale as the side view.
The 431 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The flight in question was conducted in a GA-8 Airvan Commuter aircraft, registered as N13AV. The departure roll took place on runway 30 at EGPK Glasgow Prestwick Airport, with a takeoff distance of 158 meters, which accounted for 6% of the runway. The liftoff speed was 82 knots.
The local weather conditions at the time of departure were characterized by a temperature of 16 degrees Celsius and a wind speed of 2 knots from a direction of 270 degrees. This resulted in a crosswind of 1 knot and a headwind of 2 knots. The aircraft entered a right-hand pattern from runway 30, completing the turn in less than 1 nautical mile in 24 seconds.
As the aircraft continued its pattern, it encountered a crosswind from runway 30, which it navigated in less than 1 nautical mile in 20 seconds. The downwind turn was executed at an angle of 81.3 degrees to the runway, covering a distance of 1 nautical mile. The downwind leg itself spanned 2 nautical miles and took 73 seconds to complete.
The base leg turn was made at an angle of 50.9 degrees to the runway, covering a distance of 2 nautical miles. The base leg itself was completed in less than 1 nautical mile in 40 seconds. The final turn was executed in less than 1 nautical mile in 30 seconds, setting the aircraft up for its final approach to runway 30.
The final approach was made from the south-east, heading 302.0 degrees at 1 nautical mile and 373 feet above ground level. The landing on runway 30 was successful, with a touchdown distance of 431 meters. However, the touchdown speed of 69 knots was a little fast, and the touchdown rate was smooth at -110 feet per minute.
The runway touchdown alignment was perfect, and the local weather conditions at the time of landing were characterized by a temperature of 20 degrees Celsius and a wind speed of 3 knots from a direction of 227 degrees. This resulted in a crosswind of 3 knots and a headwind of 1 knot. The total landing distance was 1,371 meters, which accounted for 50% of the runway. The runway rollout alignment was also perfect.
The total flight distance was 8 nautical miles, and the flight duration was 6 minutes. The aircraft used -3 kilograms of fuel during the flight.
The GA-8 Airvan Commuter N13AV successfully landed at EGPK Glasgow Prestwick Airport, achieving a score of 90.1%. The aircraft approached the runway from the south east, heading 302.0° at 1 nautical mile and 373 feet above ground level (agl). The final approach was made to runway 30, which has a length of 2,737 meters.
Upon landing, the aircraft's performance was evaluated. The threshold height at 74 feet agl was found to be well above the target, indicating a safe margin for landing. However, the threshold speed was too high at 82 knots, suggesting that the pilot may have been able to reduce the speed further to achieve a more optimal landing.
The touchdown distance of 431 meters was considered good, indicating that the aircraft was able to maintain control and stability during the landing. The touchdown speed of 69 knots was a little fast, but the smooth touchdown rate of -110 feet per minute (fpm) suggests that the pilot was able to absorb the impact effectively. The runway touchdown alignment was perfect, indicating that the aircraft was properly aligned with the runway.
The local weather conditions at the time of landing were favorable, with a temperature of 20°C and a wind speed of 3 knots at 227°. The crosswind component was 3 knots, while the headwind component was 1 knot. These conditions did not appear to have a significant impact on the landing.
The total landing distance of 1,371 meters was 50% of the runway length, indicating that the aircraft was able to stop safely within the available distance. The runway rollout alignment was also perfect, suggesting that the pilot was able to maintain control and stability during the rollout phase.
Overall, the landing of the GA-8 Airvan Commuter N13AV at EGPK Glasgow Prestwick Airport was successful, with a score of 90.1%. While there were some minor issues with the threshold speed and touchdown speed, the aircraft's performance was generally good, and the pilot was able to maintain control and stability throughout the landing.
