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 5,000 ft of the approach.
Plan view — the first 5,000 ft of the 6,693 ft runway, to the same scale as the side view.
Touched down 1,888 ft past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The flight began with a departure roll from runway 33 at KASE Aspen-Pitkin County Airport (Sardy Field), a small airport in Aspen, Colorado. The TBM 930 aircraft took off with a takeoff distance of 747 feet, which was 11% of the runway. The liftoff speed was 56 knots, and the local weather conditions were characterized by a temperature of 63°F and a wind speed of 11 knots from 239 degrees.
As the aircraft climbed out of the airport, it began its enroute climb, which started overhead the airport and continued for 2 minutes, covering a distance of 5 nautical miles. The aircraft then leveled off and entered a cruise phase, which lasted for 2 minutes and covered another 5 nautical miles. This was followed by another climb phase, which started 1 mile southwest of Basalt, Colorado, and took the aircraft from 12,614 feet to 26,446 feet in 15 minutes, covering a distance of 41 nautical miles.
The aircraft then entered another cruise phase, which lasted for 7 minutes and covered 31 nautical miles. However, this was followed by a descent phase, which started 2 miles northwest of Cholla Airport in Walsenburg, Colorado, and took the aircraft from 26,316 feet to 11,250 feet in 5 minutes, covering a distance of 22 nautical miles. The aircraft then leveled off again and entered another cruise phase, which lasted for 7 minutes and covered 13 nautical miles.
The final approach to runway 09 at KTEX Telluride Regional Airport was made from the west, with the aircraft heading 112.0 degrees at 4 nautical miles and 1,219 feet above ground level. The landing was made on a runway with a length of 6,693 feet, and the threshold height was slightly above the target. The threshold speed was excessively high at 109 knots, and the touchdown point was 510 feet beyond the touchdown zone. The touchdown speed was also excessively fast at 106 knots, and the touchdown rate was very heavy at -915 feet per minute.
The runway touchdown position was slightly misaligned by 14 feet from the centerline, and the runway rollout alignment was also slightly misaligned by 37 feet from the centerline. The local weather conditions at the time of landing were characterized by a temperature of 52°F and a wind speed of 4 knots from 120 degrees. The crosswind was 1 knot, and the headwind was 4 knots.
The total landing distance was 3,765 feet, which was 56% of the runway. The total flight distance was 122 nautical miles, and the flight duration was 41 minutes. Notably, the aircraft used 0 pounds of fuel during the flight.
The TBM 930 aircraft successfully landed at KTEX Telluride Regional Airport, but the landing was not without its issues. The final approach was conducted from the west, heading 112.0° at 4 nautical miles and 1,219 feet above ground level (agl). The aircraft touched down on runway 09, which has a length of 6,693 feet.
However, the landing was not perfectly executed. The threshold height at 59 feet agl was slightly above the target, indicating that the aircraft may have been slightly high on its approach. Additionally, the threshold speed was excessively high at 109 knots, which could have contributed to the issues that followed. The touchdown point was 510 feet beyond the touchdown zone, and the touchdown speed of 106 knots was also excessively fast. Furthermore, the touchdown rate was very heavy at -915 feet per minute, which is a significant concern.
The runway touchdown position was slightly misaligned by 14 feet from the centreline, which could have made the landing more challenging. The local weather conditions were relatively calm, with a temperature of 52°F and a wind of 4 knots at 120°. The crosswind was minimal at 1 knot, and the headwind was 4 knots, which was actually beneficial for the landing.
The total landing distance was 3,765 feet, which is 56% of the runway length. This is a relatively long landing distance, indicating that the aircraft may have been slowed down too quickly or that the pilot may have been too aggressive on the approach. The runway rollout alignment was also slightly misaligned by 37 feet from the centreline, which could have made the landing more difficult.
Overall, while the TBM 930 aircraft successfully landed at KTEX Telluride Regional Airport, the landing was not perfectly executed, and there were several issues that need to be addressed. The high threshold speed, excessive touchdown speed, and heavy touchdown rate are all concerns that need to be addressed to improve the safety and efficiency of the landing.
