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.

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 2,218 ft of the approach.
Plan view — the full 2,218 ft runway, to the same scale as the side view.
The 960 ft touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The flight began with a departure roll from runway 04 at AZ03 Cliff Dwellers Lodge Airport. The aircraft, Sirius, took off with a takeoff distance of 555 feet, which accounted for 14% of the runway. The liftoff speed was 54 knots. At the time of departure, the local weather conditions were characterized by a temperature of 36 degrees Fahrenheit and a wind speed of 3 knots from a direction of 217 degrees. This resulted in a crosswind of 1 knot and a tailwind of 3 knots.
As the aircraft climbed away from the airport, it began its enroute climb, which started overhead AZ03 Cliff Dwellers Lodge Airport Marble Canyon. The aircraft climbed from an altitude of 4,704 feet above sea level to 5,123 feet above sea level, an increase of 419 feet in just 1 minute, covering a distance of less than 1 nautical mile. Following this initial climb, the aircraft entered a level cruise phase, which lasted for 10 minutes and covered a distance of 17 nautical miles. This cruise phase took place 1 mile north-east of the airport.
The aircraft then began another enroute climb, this time starting 1 mile north of RB19 Glen Canyon Dam Page. The climb from 5,081 feet above sea level to 6,323 feet above sea level was a significant increase of 1,242 feet in just 2 minutes, covering a distance of 3 nautical miles. After this climb, the aircraft entered a descent phase, which started 3 miles east of 22UT Larkspur Airstrip Big Water. The descent from 6,325 feet above sea level to 4,163 feet above sea level was a decrease of 2,162 feet in 4 minutes, covering a distance of 4 nautical miles.
The final approach to runway 04 at 22UT Larkspur Airstrip was made from the south-west, with a heading of 50.0 degrees at an altitude of 88 feet above ground level and a distance of 0 nautical miles from the runway. The landing on runway 04 was successful, with a touchdown distance of 952 feet, which was good considering the runway length of 2,218 feet. However, the touchdown speed of 78 knots was excessively fast, and the threshold speed was also high at 89 knots. The touchdown rate was good at -195 feet per minute, and the runway touchdown alignment was perfect.
The local weather conditions at the time of landing were the same as at the time of departure, with a temperature of 36 degrees Fahrenheit and a wind speed of 3 knots from a direction of 217 degrees. This resulted in a crosswind of 1 knot and a tailwind of 3 knots. The total landing distance was 1,376 feet, which accounted for 62% of the runway. The runway rollout alignment was also perfect. The total flight distance was 26 nautical miles, and the flight duration was 18 minutes. The aircraft used 9 pounds of fuel during the flight.
The Sirius aircraft successfully landed at Larkspur Airstrip, achieving an overall score of 88.5%. The final approach to runway 04 from the south-west was executed at a heading of 50.0°, with the aircraft at 0 nm and 88 ft above ground level (agl). The landing was completed on runway 04, which has a length of 2,218 ft.
The threshold height was satisfactory, but the threshold speed was excessively high at 89 kn, indicating that the pilot may have been able to slow down more efficiently before touchdown. The touchdown distance of 952 ft was considered good, suggesting that the pilot had sufficient control over the aircraft's descent. However, the touchdown speed of 78 kn was excessively fast, which may have put additional stress on the aircraft's landing gear.
The touchdown rate of -195 fpm was deemed good, indicating that the pilot had managed to control the aircraft's descent effectively. The runway touchdown alignment was perfect, demonstrating the pilot's skill in aligning the aircraft with the runway. The local weather conditions at the time of landing were characterized by a temperature of 36 °F and a wind speed of 3 kn from 217°.
The crosswind component was minimal at 1 kn, while the tailwind component was 3 kn. These conditions were favorable for the landing, allowing the pilot to maintain control of the aircraft. The total landing distance of 1,376 ft was 62% of the runway length, indicating that the pilot had managed to bring the aircraft to a stop within a reasonable distance.
The runway rollout alignment was also perfect, demonstrating the pilot's ability to maintain control of the aircraft during the rollout phase. Overall, the landing was considered successful, with the pilot demonstrating good control and management of the aircraft throughout the approach and landing phases.
