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 7,901 ft runway, to the same scale as the side view.
The 1,205 ft touchdown sits inside 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 10 minutes and covered a distance of 2 nautical miles. The aircraft, a Cessna CJ4 Citation, then departed from runway 23 at KBUF Buffalo Niagara International Airport. The takeoff distance was 1,035 meters, which accounted for 45% of the runway. The liftoff speed was 164 knots.
The local weather conditions at the time of departure were characterized by a temperature of 10 degrees Celsius and a wind speed of 27 knots from a direction of 229 degrees. This resulted in a crosswind of 3 knots and a headwind of 27 knots. The aircraft then began its enroute climb, starting overhead Sloan in New York, United States. The climb took 6 minutes and covered a distance of 21 nautical miles, during which the aircraft ascended from an altitude of 1,654 feet above sea level to 7,836 feet above sea level, an increase of 6,181 feet.
Following the enroute climb, the aircraft entered a level cruise, starting 2 miles south east of CYSN Niagara District Airport in Niagara-on-the-Lake, Ontario, Canada. This cruise lasted for 2 minutes and covered a distance of 7 nautical miles. The aircraft then began its enroute descent, starting 3 miles north west of St. Catharines, Ontario, Canada. The descent took 5 minutes and covered a distance of 20 nautical miles, during which the aircraft descended from an altitude of 8,335 feet above sea level to 2,972 feet above sea level, a decrease of 5,363 feet.
The aircraft then entered another level cruise, starting 4 miles south of New Toronto, Ontario, Canada. This cruise lasted for 2 minutes and covered a distance of 8 nautical miles. The final approach to runway 33L at CYYZ Toronto Lester B. Pearson International Airport was made from the south east, heading 309.0 degrees at a distance of 3 nautical miles and an altitude of 1,742 feet above ground level.
The landing on runway 33L was successful, with a touchdown distance of 369 meters, which was 45% of the runway length. However, the threshold speed was excessively high at 145 knots, and the touchdown speed was excessively fast at 136 knots. The touchdown rate was fair at -280 feet per minute, and the runway touchdown alignment was very good. The local weather conditions at the time of landing were characterized by a temperature of 6 degrees Celsius and a wind speed of 22 knots from a direction of 300 degrees, resulting in a crosswind of 6 knots and a headwind of 21 knots.
The aircraft then taxied to the parking from the runway, which took 12 minutes and covered a distance of 1 nautical mile. The total flight distance was 67 nautical miles, and the flight duration was 32 minutes. The aircraft used 183 kilograms of fuel during the flight.
The Cessna CJ4 Citation aircraft successfully landed on runway 33L at CYYZ Toronto Lester B. Pearson International Airport, achieving a score of 82.1%. The final approach was initiated from the southeast, heading 309.0° at a distance of 3 nautical miles and an altitude of 1,742 feet above ground level (agl). The aircraft's approach to the runway was satisfactory, with a good threshold height and a touchdown distance of 369 meters, which is within acceptable limits.
However, there were some areas of concern during the landing. The threshold speed was excessively high at 145 knots, which may have put additional stress on the aircraft's landing gear and brakes. Additionally, the touchdown speed of 136 knots was also excessively fast, which could have resulted in a longer rollout distance and increased the risk of overrunning the runway. The touchdown rate of -280 feet per minute (fpm) was fair, but could have been improved with a more controlled descent.
The local weather conditions at the time of the landing were characterized by a temperature of 6°C and a wind speed of 22 knots from 300°. This resulted in a crosswind of 6 knots and a headwind of 21 knots, which may have affected the aircraft's approach and landing. Despite these conditions, the runway touchdown alignment was very good, indicating that the pilot maintained a stable and controlled approach.
The total landing distance of 1,090 meters was 45% of the runway length, which is within acceptable limits. However, the runway rollout alignment was misaligned by 15.9 meters from the centreline, which may have resulted in a longer rollout distance and increased the risk of overrunning the runway. Overall, the landing was satisfactory, but there were some areas of concern that could be improved upon in future landings.
