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: seven 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.
At the 500 ft gate: sink rate above what the glideslope needed, off the runway's 3° glideslope, off the centreline and speed above the reference speed.
The approach, gate by gate
Side view — the last 3,292 m of the approach.
Plan view — the first 3,292 m of the 3,990 m runway, to the same scale as the side view.
Touched down 1,343 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
This flight was operated by a Boeing 777-200ER aircraft. The taxiing process from the parking area to the runway took approximately 2 minutes and covered a distance of less than 1 nautical mile. The departure roll took place on runway 07C at Frankfurt Airport (EDDF), with a takeoff distance of 1,523 meters, which accounted for 38% of the runway length. The aircraft lifted off at a speed of 159 knots.
During the initial climb, the aircraft departed from Frankfurt Airport, climbing from an altitude of 922 feet above sea level to 1,208 feet above sea level, an increase of 286 feet, over a distance of 2 nautical miles, and within a time frame of 3 minutes. The climb took place overhead Frankfurt Airport, with the aircraft heading in a northeasterly direction.
As the aircraft approached the destination, it began its final descent onto runway 25C at Frankfurt Airport, coming in from the east at a heading of 250.0 degrees. The aircraft was at an altitude of 807 feet above ground level and was 1 nautical mile away from the runway.
The landing took place on runway 25C, which had a length of 3,990 meters. The threshold height was satisfactory, but the threshold speed was excessively high at 266 knots. The touchdown point was 965 meters beyond the touchdown zone, and the touchdown speed was also excessively fast at 239 knots. The touchdown rate was firm at -340 feet per minute. Furthermore, the runway touchdown position was misaligned by 14.5 meters from the centerline.
The local weather conditions at the time of landing were characterized by a temperature of 20 degrees Celsius, with a wind speed of 3 knots from a direction of 220 degrees. The crosswind component was 2 knots, while the headwind component was 3 knots. The total landing distance was 3,244 meters, accounting for 81% of the runway length. Additionally, the runway rollout alignment was excessively misaligned by 224.1 meters from the centerline.
In conclusion, the total flight distance was 6 nautical miles, and the flight duration was 5 minutes. The aircraft used a total of -5 kilograms of fuel during the flight.
The Boeing 777-200ER aircraft has successfully landed at Frankfurt Airport (EDDF), but the landing was not without its issues. The aircraft was approaching the runway from the east, heading 250.0° at 1 nautical mile and 807 feet above ground level (agl). The final approach was made to runway 25C, which has a length of 3,990 meters.
Upon landing, the threshold height was reported as good, but the threshold speed was excessively high at 266 knots. This indicates that the aircraft was traveling at a speed that was higher than recommended for a safe landing. The touchdown point was 965 meters beyond the touchdown zone, which suggests that the aircraft may have been slightly off-centerline during the landing. The touchdown speed was also reported as excessively fast at 239 knots, which could have contributed to the firm touchdown rate of -340 feet per minute (fpm).
The local weather conditions at the time of the landing were relatively calm, with a temperature of 20°C and a wind speed of 3 knots from 220°. The crosswind was minimal at 2 knots, and the headwind was 3 knots. Despite the favorable weather conditions, the aircraft's landing performance was not ideal.
One of the most notable issues with the landing was the runway touchdown position, which was misaligned by 14.5 meters from the centerline. This suggests that the aircraft may have been slightly off-centerline during the landing, which could have contributed to the excessive rollout alignment misalignment of 224.1 meters from the centerline. The total landing distance was 3,244 meters, which is 81% of the runway length. This indicates that the aircraft was able to stop within a reasonable distance, but the landing performance could have been improved.
Overall, while the Boeing 777-200ER aircraft was able to land safely at Frankfurt Airport, the landing performance was not ideal. The excessively high threshold speed, fast touchdown speed, and misaligned runway touchdown position all contributed to a landing that could have been improved.
