Shorten the long landing
Ground effect becomes significant below about one wingspan of height. A Cessna 172, with a 36 ft span, enters ground effect at flare height - the float it feels in the hold-off is ground effect arriving on cue. An A320, with a span around 117 ft, has been in ground effect since before the threshold and there is no sudden cushion to feel, only a gradual reduction in induced drag that lengthens any float you allow.

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 6,971 ft runway, to the same scale as the side view.
The 65 ft touchdown sits inside the full-score zone. The 2.87 G arrival is the firm side of smooth.
The rest of the report
The flight began with a departure roll from runway 20 at PHJH Kapalua Airport. The Vision Jet took off with a takeoff distance of 2,140 feet, which was 70% of the runway length. The liftoff speed was 99 knots. The local weather conditions at the time of departure were characterized by a temperature of 81 degrees Fahrenheit and a wind speed of 4 knots at 66 degrees, resulting in a crosswind of 2 knots and a tailwind of 3 knots.
As the aircraft climbed out of PHJH Kapalua Airport, it began its enroute climb, reaching an altitude of 16,396 feet above sea level. This climb was achieved in 9 minutes, covering a distance of 28 nautical miles, and involved an increase of 15,815 feet in altitude. The aircraft then began its first descent, which started 14 miles south of Maunaloa and ended at an altitude of 2,001 feet above sea level, a decrease of 14,392 feet in 9 minutes, covering 35 nautical miles.
The aircraft then began another climb, this time from 2,001 feet to 5,263 feet above sea level, an increase of 3,263 feet in 2 minutes, covering 7 nautical miles. Following this climb, the aircraft entered a level cruise, lasting 2 minutes and covering 7 nautical miles. The aircraft then began another descent, this time from 5,400 feet to 2,012 feet above sea level, a decrease of 3,388 feet in 4 minutes, covering 8 nautical miles.
The aircraft then entered another level cruise, lasting 2 minutes and covering 7 nautical miles, this time starting 5 miles south of PHJR Kalaeloa Airport. The final approach to runway 04L at PHNL Daniel K Inouye International Airport was made from the southwest, heading 50.0 degrees at 4 nautical miles and 1,516 feet above ground level.
The landing on runway 04L was successful, with a touchdown distance of 662 feet, which was 9% of the runway length. However, the touchdown speed was fast at 79 knots, and the touchdown rate was very heavy at -930 feet per minute. The runway touchdown position was significantly misaligned by 72 feet from the centreline. The local weather conditions at the time of landing were characterized by a temperature of 78 degrees Fahrenheit and a wind speed of 11 knots at 150 degrees, resulting in a crosswind of 11 knots and a tailwind of 1 knot.
After landing, the aircraft taxied to the parking area, taking 6 minutes and covering less than 1 nautical mile. The total flight distance was 96 nautical miles, and the flight duration was 39 minutes. The aircraft used 274 pounds of fuel during the flight.
The Vision Jet aircraft has successfully landed at PHNL Daniel K Inouye International Airport, but with some notable areas for improvement. The final approach was initiated from the southwest, heading 50.0° at a distance of 4 nautical miles and an altitude of 1,516 feet above ground level. The aircraft touched down on runway 04L, which has a length of 6,971 feet.
Upon landing, the threshold height was reported as good, but the threshold speed was significantly above the target speed at 78 knots. This may indicate that the pilot may have been able to flare the aircraft more effectively to reduce the touchdown speed. The touchdown distance was good at 52 feet, but the touchdown speed of 79 knots was faster than desired. The touchdown rate was also very heavy at -930 feet per minute, which may have contributed to the fast touchdown speed.
One of the most notable issues with this landing was the significant misalignment of the runway touchdown position, which was 72 feet off the centreline. This may have been due to a combination of factors, including crosswind and tailwind conditions. The local weather conditions at the time of landing were characterized by a temperature of 78°F and winds of 11 knots at 150°. The crosswind component was 11 knots, while the tailwind component was only 1 knot.
The total landing distance was 662 feet, which is 9% of the runway length. This is a relatively short landing distance, but it may have been influenced by the heavy touchdown rate and the misaligned runway touchdown position. The runway rollout alignment was also misaligned by 92 feet from the centreline, which may have been a result of the pilot's difficulty in maintaining control of the aircraft during the rollout phase.
Overall, while the Vision Jet aircraft has successfully landed at PHNL Daniel K Inouye International Airport, there are several areas for improvement, including reducing the touchdown speed, improving the runway touchdown position, and maintaining better control during the rollout phase.
