Work on the flare
Arrive slow and the sink rate at the threshold is already above schedule, the flare is short because there is no energy to extend it, and the touchdown is hard in a way that feels exactly like a late flare. Diagnosing a slow arrival as a late flare is the catastrophic misread: you respond by flaring earlier, which bleeds more speed, which makes the next one worse. The tiebreaker is threshold speed against VRef, not feel. Never diagnose a flare without it.

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 9,185 ft runway, to the same scale as the side view.
Touched down 2,185 ft past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The flight began with a departure roll from runway 27 at Linden Airport (KLDJ), where the aircraft, a Junkers F13, took off with a takeoff distance of 666 feet, which accounted for 21% of the runway. The liftoff speed was 63 knots. At the time of departure, the local weather conditions were characterized by a temperature of 60°F and winds of 4 knots at 20°, resulting in a crosswind of 4 knots and a tailwind of 3 knots.
The enroute level cruise started shortly after takeoff, with the aircraft flying overhead Linden, New Jersey, for less than a minute and covering less than a nautical mile. This brief cruise was followed by an enroute climb, which began overhead Linden and took the aircraft from an altitude of 294 feet above sea level to 1,973 feet, an increase of 1,679 feet in just 5 minutes, covering a distance of 6 nautical miles.
The aircraft then entered another enroute level cruise, this time flying overhead Westerleigh, New York, for 5 minutes and covering 7 nautical miles. Following this cruise, the enroute descent started overhead Brooklyn, New York, where the aircraft descended from 2,746 feet above sea level to 258 feet, a decrease of 2,488 feet in 4 minutes, covering a distance of 6 nautical miles.
The final approach to runway 13R at John F. Kennedy International Airport (KJFK) was made from the northwest, with the aircraft heading 122.0° at 1 nautical mile and 241 feet above ground level. The landing on runway 13R was notable for several factors, including a touchdown point that was 736 feet beyond the touchdown zone, a touchdown speed of 55 knots, and a touchdown rate of -77 feet per minute, which was excellent.
However, the landing was also marred by a threshold height that was significantly above target and a threshold speed that was too high at 75 knots. Additionally, the runway touchdown position was misaligned by 50 feet from the centreline, and the runway rollout alignment was misaligned by 53 feet from the centreline. The local weather conditions at the time of landing were characterized by a temperature of 55°F and winds of 8 knots at 83°, resulting in a crosswind of 5 knots and a headwind of 6 knots.
The total landing distance was 3,986 feet, which accounted for 43% of the runway. The taxiing to the parking from the runway took 1 minute and covered less than 1 nautical mile. The total flight distance was 21 nautical miles, and the flight used 225 pounds of fuel, taking a total of 17 minutes to complete.
The Junkers F13 aircraft successfully landed on runway 13R at KJFK John F Kennedy International Airport, but the landing was not without its challenges. The final approach was initiated from the northwest, heading 122.0° at 1 nm and 241 ft above ground level (agl). The aircraft touched down on the runway, but the touchdown point was 736 ft beyond the designated touchdown zone, indicating a slight deviation from the intended landing spot.
The landing speed of 55 kt was within the acceptable range, and the touchdown rate of -77 fpm was excellent, indicating a smooth and controlled descent. However, the threshold height at 80 ft agl was significantly above the target, suggesting that the aircraft may have been higher than intended at the point of touchdown. Additionally, the threshold speed of 75 kt was too high, indicating that the aircraft may have been descending too quickly or that the pilot may have been unable to slow down sufficiently before touchdown.
The runway touchdown position was misaligned by 50 ft from the centreline, which could have been due to a variety of factors, including wind or pilot error. The local weather conditions at the time of the landing were relatively calm, with a temperature of 55°F and winds of 8 kt at 83°. The crosswind was 5 kt, and the headwind was 6 kt, which may have contributed to the misalignment.
The total landing distance of 3,986 ft was 43% of the runway length, which is within the acceptable range. However, the runway rollout alignment was misaligned by 53 ft from the centreline, which could have been due to the same factors that contributed to the initial misalignment.
Overall, while the landing was successful, there were several areas for improvement, including the threshold height and speed, the runway touchdown position, and the runway rollout alignment. These issues will need to be addressed in order to ensure a safe and efficient landing in the future.
