Keep the approach speed on target
Every knot above Vref is stored kinetic energy, and energy stored at the threshold must be dissipated in ground effect before the aeroplane will stop flying. Because kinetic energy scales with the square of speed, the excess you must dissipate grows fast. At a 45-knot approach, five knots hot is over a tenth more speed and roughly a quarter more energy to get rid of in ground effect. This is why the fix is never in the flare. It was decided three miles earlier, on final, at the airspeed indicator.

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 1,230 m of the approach.
Plan view — the full 1,230 m runway, to the same scale as the side view.
Touched down 545 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The Edgley Optica aircraft departed from runway 18 at EDFB Reichelsheim Airfield, covering a takeoff distance of 397 meters, which accounted for 32% of the runway. The aircraft lifted off at a speed of 65 knots. At the time of departure, the local weather conditions were characterized by a temperature of 10 degrees Celsius and a gentle wind of 4 knots blowing from 189 degrees. This resulted in a crosswind of 1 knot and a headwind of 4 knots.
As the aircraft climbed to a higher altitude, it began its enroute climb overhead Florstadt in Hessen, Germany. The aircraft ascended from an initial altitude of 722 feet above sea level to 1,821 feet, a vertical increase of 1,099 feet, within a span of just 3 minutes. During this climb, the aircraft covered a distance of 2 nautical miles.
Upon reaching the desired altitude, the aircraft initiated its final approach to runway 18 at EDFB Reichelsheim Airfield. The approach was made from the north, with the aircraft heading in a direction of 176.0 degrees at an altitude of 1,407 feet above ground level and a distance of 1 nautical mile from the runway.
The landing on runway 18 was not entirely smooth, as the threshold height was above the target, and the threshold speed was excessively high at 90 knots. The touchdown point was located 106 meters beyond the designated touchdown zone, and the touchdown speed was also excessively fast at 63 knots. However, the touchdown rate was smooth, with a descent rate of -144 feet per minute. The runway touchdown alignment was very good, indicating that the pilot had maintained a stable approach.
The total landing distance covered by the aircraft was 956 meters, which accounted for 78% of the runway. Although the runway rollout alignment was slightly misaligned by 7.8 meters from the centerline, the overall landing was considered smooth. The local weather conditions remained the same, with a temperature of 10 degrees Celsius and a gentle wind of 4 knots blowing from 188 degrees, resulting in a crosswind of 1 knot and a headwind of 4 knots.
In conclusion, the Edgley Optica aircraft completed a flight of 4 nautical miles, which took approximately 5 minutes to complete. The aircraft used a total of 3 kilograms of fuel during the flight.
The Edgley Optica aircraft has successfully landed at EDFB Reichelsheim Airfield, but with some areas for improvement. The final approach to runway 18 was initiated from the north, heading 176.0° at a distance of 1 nautical mile and an altitude of 1,407 feet above ground level (agl). The aircraft touched down on the runway, but with some notable issues.
The threshold height at 61 feet agl was above the target, indicating that the aircraft may have been slightly high on its approach. Additionally, the threshold speed was excessively high at 90 knots, which could have contributed to the high touchdown speed. The touchdown point was 106 meters beyond the touchdown zone, which is a significant deviation from the intended landing spot.
The touchdown speed of 63 knots was also excessively fast, which could have put additional stress on the aircraft's landing gear and potentially compromised the safety of the landing. However, the touchdown rate was smooth at -144 feet per minute, which is a positive aspect of the landing. The runway touchdown alignment was very good, indicating that the aircraft was properly aligned with the runway during the landing.
The local weather conditions at the time of the landing were relatively calm, with a temperature of 10°C and a wind speed of 4 knots from 188°. The crosswind was minimal at 1 knot, while the headwind was 4 knots, which may have contributed to the high touchdown speed.
The total landing distance was 956 meters, which is 78% of the runway length. This is a relatively long landing distance, but it is not excessively long. However, the runway rollout alignment was slightly misaligned by 7.8 meters from the centerline, which could have been a result of the high touchdown speed and the aircraft's momentum.
Overall, while the Edgley Optica aircraft has successfully landed at EDFB Reichelsheim Airfield, there are some areas for improvement, particularly with regards to the threshold speed, touchdown speed, and runway rollout alignment. With some adjustments to the approach and landing technique, the aircraft could potentially achieve a more precise and controlled landing.
