Improve the landing
Not the biggest loss in points — the one thing on this flight a check pilot would raise first, and the guide passage for it.
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.

Two stabilised approach gates, each with six checks at 1,000 ft and 500 ft above the runway.
The approach, gate by gate
Side view — the last 1,031 m of the approach.
Plan view — the full 1,031 m runway, to the same scale as the side view.
The 210 m touchdown sits inside the full-score zone. The 2.78 G arrival is the firm side of smooth.
The rest of the report
The flight in question was conducted on an F-35A Lightning II aircraft. The pre-flight taxiing process took 5 minutes and covered a distance of 1 nautical mile. The aircraft then departed from runway 34 at CYFB Iqaluit Airport, with a takeoff distance of 603 meters, which accounted for 23% of the runway. The liftoff speed was 179 knots.
The local weather conditions at the time of departure were characterized by a temperature of 7 degrees Celsius and a wind speed of 16 knots from a direction of 329 degrees. This resulted in a crosswind of 4 knots and a headwind of 16 knots. The aircraft then began its enroute climb, which started overhead CYFB Iqaluit Airport and continued to an altitude of 38,982 feet above sea level, an increase of 38,031 feet in 8 minutes and covering a distance of 72 nautical miles.
Following the enroute climb, the aircraft entered a level cruise phase, which started 70 miles east of CYLC Kimmirut Airport and lasted for 21 minutes, covering a distance of 208 nautical miles. The aircraft then began its enroute descent, which started 35 miles north of CYLU Kangiqsualujjuaq (Georges River) Airport and continued to an altitude of 957 feet above sea level, a decrease of 39,240 feet in 3 minutes and covering a distance of 22 nautical miles.
The aircraft then entered another level cruise phase, which started 12 miles north of CYLU Kangiqsualujjuaq (Georges River) Airport and lasted for 3 minutes, covering a distance of 12 nautical miles. The final approach to runway 16 at CYLU Kangiqsualujjuaq (Georges River) Airport was conducted from the north-west, with a heading of 146.0 degrees at an altitude of 631 feet above ground level and a distance of 1 nautical mile from the runway.
The landing on runway 16 was conducted with a runway length of 1,031 meters. The threshold height at 63 feet above ground level was above the target, and the threshold speed was too high at 188 knots. The touchdown distance was good at 196 meters, but the touchdown speed of 182 knots was fast, and the touchdown rate was very heavy at -1,741 feet per minute. The runway touchdown position was slightly misaligned by 3.3 meters from the centreline.
The local weather conditions at the time of landing were characterized by a temperature of 14 degrees Celsius and a wind speed of 5 knots from a direction of 289 degrees, resulting in a crosswind of 2 knots and a tailwind of 5 knots. The total landing distance was 691 meters, which accounted for 67% of the runway. The runway rollout alignment was slightly misaligned by 10.0 meters from the centreline.
The total flight distance was 318 nautical miles, and the flight duration was 40 minutes. The aircraft used a total of -4,028 kilograms of fuel during the flight.
The F-35A Lightning II aircraft successfully landed at CYLU Kangiqsualujjuaq (Georges River) Airport, but the landing was not without its challenges. The aircraft was approaching the runway from the north-west, heading 146.0° at 1 nm and 631 ft above ground level (agl). The landing was made on runway 16, which has a length of 1,031 m.
The threshold height at 63 ft agl was above the target, indicating that the aircraft was slightly higher than desired when it reached the threshold of the runway. Additionally, the threshold speed was too high at 188 kt, which may have contributed to the subsequent issues with the landing. The touchdown distance was good at 196 m, but the touchdown speed of 182 kt was faster than desired, resulting in a very heavy touchdown rate of -1,741 fpm.
The runway touchdown position was slightly misaligned by 3.3 m from the centreline, which may have been due to the high speed at touchdown. The local weather conditions were relatively calm, with a temperature of 14 °C and a wind of 5 kt at 289°. The crosswind was minimal at 2 kt, but the tailwind of 5 kt may have contributed to the issues with the landing.
The total landing distance was 691 m, which is 67% of the runway length. This is a relatively short distance, but it may have been due to the high speed at touchdown. The runway rollout alignment was also slightly misaligned by 10.0 m from the centreline, which may have been due to the high speed and heavy touchdown rate.
Overall, the landing was not perfect, but the aircraft was able to safely touch down on the runway. However, the high speed at touchdown and the heavy touchdown rate may have put additional stress on the aircraft and its systems.
