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 10,014 ft of the approach.
Plan view — the full 10,014 ft runway, to the same scale as the side view.
Touched down 6,590 ft past the threshold — beyond 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 10 minutes and covered a distance of 2 nautical miles. The aircraft, a Boeing 737-800, then departed from runway 27 at Miami International Airport (KMIA). The takeoff distance was 5,057 feet, which accounted for 43% of the runway. The liftoff speed was 166 knots.
As the aircraft took to the skies, it encountered local weather conditions with a temperature of 83 degrees Fahrenheit and a wind speed of 2 knots at 290 degrees. The crosswind was 1 knot, and the headwind was 2 knots. The enroute climb started approximately 1 mile northeast of Fountainebleau, Florida, where the aircraft climbed from 1,033 feet above sea level to 29,039 feet above sea level, an increase of 28,006 feet in 23 minutes, covering a distance of 125 nautical miles.
The enroute level cruise began 2 miles east of Blanket Bay Airport (6FD5) at Yeehaw Junction, Florida, and lasted for 24 minutes, covering a distance of 152 nautical miles. The aircraft then started another enroute climb 3 miles west of Jacksonville Naval Air Station (KNIP) at Jacksonville, Florida, where it climbed from 32,004 feet above sea level to 32,466 feet above sea level, an increase of 463 feet in 2 minutes, covering a distance of 11 nautical miles.
The enroute level cruise continued 3 miles southwest of Jacksonville International Airport (KJAX) at Jacksonville, Florida, and lasted for 67 minutes, covering a distance of 407 nautical miles. As the aircraft approached its destination, it started its enroute descent 2 miles west of Corbin, Kentucky, where it descended from 32,734 feet above sea level to 2,392 feet above sea level, a decrease of 30,342 feet in 26 minutes, covering a distance of 83 nautical miles.
The enroute level cruise resumed 3 miles southwest of Samuels Field (KBRY) at Bardstown, Kentucky, and lasted for 9 minutes, covering a distance of 21 nautical miles. The final approach to runway 35L at Louisville Muhammad Ali International Airport (KSDF) was made from the south, heading 347.0 degrees at 4 nautical miles and 1,515 feet above ground level.
The landing on runway 35L at KSDF was notable for several factors. The threshold height at 139 feet above ground level was excessively over target, and the threshold speed was excessively high at 210 knots. The touchdown point was very long, using more than 50% of the available runway. The touchdown speed at 203 knots was excessively fast, and the touchdown rate was very heavy at -831 feet per minute. Additionally, the runway touchdown position was slightly misaligned by 19 feet from the centreline.
The total landing distance was 9,543 feet, which accounted for 95% of the runway. The runway rollout alignment was slightly misaligned by 26 feet from the centreline. The total flight distance was 808 nautical miles, taking 170 minutes, and the aircraft used 15,850 pounds of fuel.
The Boeing 737-800 aircraft landed at KSDF Louisville Muhammad Ali International Airport, with a score of 56.5%. The final approach was initiated from the south, heading 347.0° at 4 nautical miles and 1,515 feet above ground level (agl). The aircraft successfully landed on runway 35L, which has a length of 10,014 feet.
However, there were several areas of concern during the landing. The threshold height at 139 feet agl was excessively over target, indicating that the aircraft touched down higher than it should have. Additionally, the threshold speed was excessively high at 210 knots, which may have contributed to the aircraft's high touchdown speed. The touchdown point was also very long, using more than 50% of the available runway, which could have increased the risk of overrun.
The touchdown speed of 203 knots was excessively fast, and the touchdown rate of -831 feet per minute (fpm) was very heavy. This suggests that the aircraft may have been experiencing a high rate of descent during the final approach, which could have been due to a variety of factors, including a high approach speed or a failure to configure the aircraft for landing.
In terms of alignment, the runway touchdown position was slightly misaligned by 19 feet from the centreline, and the runway rollout alignment was also slightly misaligned by 26 feet from the centreline. This may have been due to a combination of factors, including a crosswind or a failure to properly align the aircraft with the runway.
The local weather conditions at the time of the landing were relatively calm, with a temperature of 59°F and a wind speed of 1 knot from 269°. There was no significant crosswind or headwind, which may have contributed to the aircraft's alignment issues.
Overall, the landing was not without its challenges, and there were several areas where the pilot could have improved their performance. However, the aircraft was able to safely land on the runway, and the pilot was able to recover from any errors that may have been made during the approach.
