Shorten the long landing
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.

Two stabilised approach gates, each with six checks at 1,000 ft and 500 ft above the runway.
The approach, gate by gate
Side view — the last 1,749 m of the approach.
Plan view — the first 1,749 m of the 3,626 m runway, to the same scale as the side view.
The 296 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The flight began with a taxiing period from the parking area to the runway, which took approximately 5 minutes and covered less than 1 nautical mile. The aircraft then departed from runway 34R at Seattle-Tacoma International Airport (KSEA), with a takeoff distance of 1,218 meters, which accounted for 34% of the runway. The liftoff speed was 148 knots.
As the aircraft climbed to a higher altitude, it encountered local weather conditions with a temperature of 24 degrees Celsius. The enroute climb started overhead Riverton, Washington, where the aircraft ascended from 1,396 feet above sea level to 5,238 feet above sea level, an increase of 3,843 feet in just 2 minutes, covering a distance of 6 nautical miles.
The enroute level cruise began 1 mile south east of Seattle and lasted for 11 minutes, covering a distance of 16 nautical miles. The aircraft then started another enroute climb overhead Silverdale, Washington, where it ascended from 5,181 feet above sea level to 7,265 feet above sea level, an increase of 2,083 feet in 2 minutes, covering a distance of 8 nautical miles.
The enroute level cruise resumed 1 mile south of Gorst, Washington, and lasted for 10 minutes, covering a distance of 30 nautical miles. As the aircraft approached its destination, it began its descent 1 mile north west of Graham, Washington, where it descended from 7,264 feet above sea level to 1,369 feet above sea level, a decrease of 5,895 feet in 5 minutes, covering a distance of 18 nautical miles.
The final approach to runway 34R at KSEA was made from the south, with a heading of 0.0 degrees at 4 nautical miles and 927 feet above ground level. The landing on the runway was successful, with a touchdown distance of 292 meters, which was good. However, the touchdown speed of 138 knots was slightly too fast, and the touchdown rate was firm at -377 feet per minute. The runway touchdown alignment was perfect, and the local weather conditions remained the same.
The total landing distance was 1,670 meters, which accounted for 46% of the runway. The runway rollout alignment was also perfect. After landing, the aircraft taxied to the parking area, which took approximately 4 minutes and covered less than 1 nautical mile. The total flight distance was 85 nautical miles, and the flight duration was 36 minutes. The aircraft used 630 kilograms of fuel during the flight.
Aircraft C750 successfully landed at KSEA Seattle–Tacoma International Airport, achieving a score of 95.1%. The final approach was conducted from the south, heading directly towards the runway 34R, at a distance of 4 nautical miles and an altitude of 927 feet above ground level (agl).
Upon landing, the aircraft touched down on the runway with a good threshold height, indicating a smooth and controlled descent. However, the threshold speed was slightly above the target speed, registering at 142 knots. This may be attributed to the aircraft's approach configuration or the pilot's decision to maintain a higher speed for a more stable touchdown.
The touchdown distance of 292 meters was within acceptable limits, demonstrating the pilot's ability to control the aircraft's descent and maintain a stable approach. However, the touchdown speed of 138 knots was slightly too fast, indicating that the pilot may have been able to maintain a more controlled descent. The touchdown rate of -377 feet per minute (fpm) was firm, suggesting a controlled and stable touchdown.
The runway touchdown alignment was perfect, indicating that the pilot maintained a precise approach and aligned the aircraft with the runway centerline. The local weather conditions at the time of landing were favorable, with a temperature of 24 degrees Celsius.
The total landing distance of 1,670 meters was 46% of the runway length, indicating a relatively short landing distance. The runway rollout alignment was also perfect, demonstrating the pilot's ability to maintain control of the aircraft during the rollout phase and align it with the runway centerline.
Overall, the landing was successful, with the aircraft touching down smoothly and the pilot maintaining control throughout the rollout phase. However, there is room for improvement in terms of touchdown speed and maintaining a more controlled descent.
