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.
At the 500 ft gate: gear still up and sink rate above what the glideslope needed.
The approach, gate by gate
Side view — the last 1,524 m of the approach.
Plan view — the first 1,524 m of the 2,998 m runway, to the same scale as the side view.
Touched down 819 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
This flight was conducted in a Hawk T1 aircraft, which departed from runway 22 at RJTT Tokyo Haneda International Airport. The takeoff distance covered 34% of the runway, with a liftoff speed of 144 kt. At the time of departure, the local weather conditions consisted of a temperature of 16°C, a wind speed of 2 kt at 270°, and a crosswind of 2 kt with a headwind of 1 kt.
Upon taking off, the aircraft began its enroute climb, which started approximately 1 mile south-west of the airport, reaching an altitude of 3,230 ft asl within a minute and traveling 6 nm. This climb was a significant portion of the flight, and it was followed by a series of enroute climbs and descents as the aircraft navigated through various points across Tokyo, Yokohama, and other cities.
One notable climb occurred 3 miles north of SB16 Tokyo, where the aircraft climbed from 1,727 ft asl to 2,831 ft asl within 2 minutes and covered 6 nm. Another notable descent took place 1 mile north-west of Tokyo, where the aircraft descended from 3,008 ft asl to 745 ft asl within 2 minutes and covered 13 nm. The subsequent climbs and descents showed a gradual increase and decrease in altitude as the aircraft continued to traverse across the region.
The enroute level cruise phase began 2 miles east of Fujiyoshida (Yamanashi, Japan) and lasted for 2 minutes, covering a distance of 12 nm. This cruise phase marked a brief period of stable altitude and speed prior to the final approach.
The final approach was conducted heading 144.0° at 1 nm and an altitude of 450 ft agl, with the aircraft descending from 3,367 ft asl to 777 ft asl in 2 minutes and covering 13 nm in the descent from 5 miles south of Uenohara.
The aircraft landed on runway 16L at RJTT Tokyo Haneda International Airport, but the touchdown was characterized by a number of issues, including a touchdown point that was far beyond the 50% mark of the available runway. The touchdown speed at 160 kt was too fast, and the touchdown rate of -426 fpm was also hard. Furthermore, the runway touchdown position was misaligned by 9.9 m from the centreline.
Following the landing, the aircraft rolled out, and its position relative to the centreline was misaligned by 16.8 m. The total landing distance covered 63% of the runway, which was a considerable amount. The aircraft's performance on the runway was affected significantly due to factors such as a high threshold speed and a long landing roll.
Throughout the flight, the aircraft burned a total of 1,012 kg of fuel, achieving a flight distance of 127 nm in approximately 23 minutes.
The Hawk T1 aircraft has successfully landed at RJTT Tokyo Haneda International Airport, however, the landing was marred by several key issues. Approaching the runway from the north-west, heading 144.0° at 1 nautical mile and 450 feet above ground level (agl), the pilot faced an elevated threshold height of 74 feet agl, which was significantly above the target height.
Upon landing, the aircraft touched down with an excessively high speed of 180 kt, exceeding the optimal threshold speed. This led to a long touchdown point, using more than 50% of the available runway, which is RJTT Tokyo Haneda International Airport's 2,998-meter long runway 16L. Furthermore, the touchdown speed of 160 kt was also deemed too fast, contributing to the overall challenging nature of the landing.
One of the most critical concerns following the landing was the severe touchdown rate of -426 feet per minute (fpm), indicating a relatively hard landing. This high rate of descent may have put excessive stress on the aircraft and its landing gear. Additionally, the runway touchdown position was significantly off-centre by 9.9 meters from the centreline, indicating a possible misalignment issue during the approach.
The landing distance, at 1,902 meters or 63% of the total runway length, was relatively long, which is a clear indication of the aircraft's reduced ability to slow down efficiently after touchdown. This was further complicated by a significant misalignment, 16.8 meters from the runway's centreline, during the rollout.
Given the local weather conditions, with a temperature of 17°C and gentle winds, this landing would have been challenging even for an experienced pilot, and further training and improvement may be required for smoother and more efficient landings. The various factors contributing to this subpar landing serve as a reminder of the complexities involved in aviation and the importance of precision and skill.
