Arrival
Fly the aircraft onto the runway at the aim point instead of holding it off and letting it float further down the runway.
What happened: This landing touched down well beyond the target point on the runway, with nothing else in the approach or flare accounting for it.
Watch for: Aim point markings: touchdown at the target point on the runway.
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.
Two stabilised approach gates, each with seven checks, where the approach path is 1,000 ft and 500 ft above the runway. They are the approach's score: the checks passed out of the checks that ran.
The approach, gate by gate
Side view — the last 5,117 ft of the approach.
Plan view — the first 5,117 ft of the 7,481 ft runway, to the same scale as the side view.
Touched down 2,037 ft past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
Departing from Los Angeles International Airport (KLAX), the Boeing 737-800 began its journey by taxiing from the parking area to the runway, a process that took 10 minutes and covered a distance of 2 nautical miles. As the aircraft lined up on runway 25R, the crew initiated the departure roll, and the aircraft lifted off the ground at a speed of 162 knots. The takeoff distance of 6,380 feet was 57% of the available runway length, indicating a smooth and efficient departure.
As the aircraft climbed away from the airport, it began its enroute climb, which started approximately 1 mile northwest of El Segundo, California. The climb phase saw the aircraft ascend from an initial altitude of 1,058 feet above sea level to a cruising altitude of 34,995 feet, an increase of 33,937 feet in just 25 minutes, covering a distance of 174 nautical miles. The crew then transitioned to the enroute level cruise phase, which lasted for 144 minutes and covered a distance of 1,221 nautical miles. The aircraft remained at a steady altitude of 34,995 feet during this phase, maintaining a high level of efficiency.
As the aircraft approached its destination, it began its enroute descent, which started approximately 2 miles north of Earlville, Iowa. The descent phase saw the aircraft descend from a cruising altitude of 34,999 feet to a lower altitude of 9,469 feet, a decrease of 25,530 feet in just 18 minutes, covering a distance of 128 nautical miles. The crew then transitioned to the final approach phase, aligning the aircraft with runway 09L at Chicago O'Hare International Airport (KORD). The landing was successful, with the aircraft touching down 667 feet beyond the touchdown zone at a speed of 124 knots. The total landing distance of 4,847 feet was 65% of the available runway length, indicating a smooth and controlled touchdown. After taxiing to the parking area, the aircraft completed its journey, having covered a total distance of 1,563 nautical miles and using 20,257 pounds of fuel in the process.
The Boeing 737-800 touched down on runway 09L at KORD Chicago O'Hare International Airport with a score of 98.0%. The aircraft approached the runway from the west, heading 90.0° at 4 nm and 1,239 ft above ground level. The final approach was characterized by good quality, with a threshold height that met expectations. However, the threshold speed was slightly below the target at 131 kt, indicating a slight deceleration prior to touchdown.
The aircraft touched down 667 ft beyond the touchdown zone, with a touchdown speed of 124 kt, which was within acceptable limits. The touchdown rate of -212 fpm was fair, suggesting a moderate deceleration upon contact with the runway. Runway touchdown alignment was perfect, with the aircraft centered on the runway. The local weather conditions, with a temperature of 73 °F and a wind of 3 kt at 190°, contributed to a relatively calm landing environment. The crosswind was minimal at 2 kt, and the headwind was negligible at 0 kt.
The total landing distance of 4,847 ft was 65% of the runway length, indicating a relatively short rollout. Runway rollout alignment was perfect, with the aircraft remaining centered on the runway throughout the deceleration phase. Overall, the landing was characterized by good touchdown speed and alignment, with the only notable deviation being the slightly below-target threshold speed.
