Keep the approach speed on target
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 8,995 ft runway, to the same scale as the side view.
Touched down 2,103 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 to the runway, which took 5 minutes and covered less than 1 nautical mile. The aircraft, a Cessna CJ4 Citation, then departed from runway 02 at PHJH Kapalua Airport. The takeoff distance was 1,442 feet, which accounted for 47% of the runway. The liftoff speed was 127 knots.
The local weather conditions at the time of departure were characterized by a temperature of 82°F and a wind speed of 13 knots at 17 degrees. The crosswind component was 2 knots, while the headwind component was 13 knots. The aircraft climbed to a height of 15,106 feet above sea level, an increase of 13,789 feet from the initial altitude of 1,317 feet above sea level. This climb took place over a distance of 9 nautical miles in 3 minutes.
The enroute climb was followed by a level cruise, which started 5 miles south of 'Ualapu'e and lasted for 2 minutes, covering a distance of 12 nautical miles. The aircraft then began its descent, which started 4 miles south of Kaunakakai. The descent from 14,647 feet above sea level to 13,245 feet above sea level took 2 minutes and covered a distance of 11 nautical miles.
The aircraft then entered another level cruise phase, which started 13 miles south of Maunaloa and lasted for 2 minutes, covering a distance of 10 nautical miles. The descent from 13,203 feet above sea level to 4,041 feet above sea level took 7 minutes and covered a distance of 29 nautical miles. The aircraft then entered another level cruise phase, which started 7 miles south of SB35 Honolulu and lasted for 5 minutes, covering a distance of 10 nautical miles.
The final approach to runway 04R at PHNL Daniel K Inouye International Airport was made from the southwest, heading 52.0 degrees at 2 nautical miles and 1,781 feet above ground level. The landing on runway 04R took place at a speed of 120 knots, which was excessively fast. The touchdown point was 1,958 feet beyond the touchdown zone, and 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 82°F and a wind speed of 7 knots at 230 degrees. The crosswind component was 0 knots, while the tailwind component was 7 knots. The total landing distance was 4,928 feet, which accounted for 55% of the runway. The runway rollout alignment was significantly misaligned by 106 feet from the centreline.
The taxiing period from the runway to the parking took 6 minutes and covered less than 1 nautical mile. The total flight distance was 85 nautical miles, and the flight took 33 minutes. The aircraft used 549 pounds of fuel during the flight.
The Cessna CJ4 Citation aircraft has landed at PHNL Daniel K Inouye International Airport, but the landing was not without its issues. The final approach to runway 04R from the southwest was initiated at a height of 1,781 feet above ground level (agl) and a distance of 2 nautical miles from the runway. The aircraft was heading 52.0° at the time of the approach.
Upon landing, the aircraft touched down 1,958 feet beyond the designated touchdown zone, which is a significant deviation from the intended landing spot. The touchdown speed of 120 knots was also excessively high, indicating that the pilot may have been unable to slow the aircraft down sufficiently before touchdown. Furthermore, the touchdown rate of -896 feet per minute (fpm) was very heavy, suggesting that the aircraft may have been experiencing a high rate of descent at the time of touchdown.
The runway touchdown position was also significantly misaligned, with the aircraft deviating from the centerline by 72 feet. This misalignment was also evident during the runway rollout, where the aircraft was off-centerline by 106 feet. The excessive deviation from the centerline during both touchdown and rollout suggests that the pilot may have had difficulty maintaining control of the aircraft during the landing.
The landing distance of 4,928 feet was 55% of the available runway length, which is a relatively high percentage. This may indicate that the pilot was unable to stop the aircraft within the available runway length, or that the aircraft was experiencing a high rate of deceleration.
The local weather conditions at the time of the landing were favorable, with a temperature of 82°F and a wind speed of 7 knots from 230°. The crosswind component was negligible, but the tailwind component was 7 knots, which may have contributed to the difficulties experienced during the landing. Overall, the landing was not executed smoothly, and the pilot may have benefited from additional training or practice to improve their skills.
