Maintain the centreline
A small uncorrected heading error at 40 knots becomes a metre of offset per second by 100 knots, noticed only at rotation, producing a crabbed liftoff. Root cause is nearly always eyes on the tape instead of the far end of the runway. Small heading changes displace a distant point visibly long before the nearby centreline stripes look wrong.

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 7,641 ft runway, to the same scale as the side view.
Touched down 1,891 ft past the threshold — beyond 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 12 minutes and covered a distance of 2 nautical miles. The aircraft, a Boeing 737-900, then departed from runway 24 at Bradley International Airport (KBDL). The takeoff distance was 4,847 feet, which accounted for 51% of the runway. The liftoff speed was 156 knots.
The local weather conditions at the time of departure were characterized by a temperature of 68°F and winds of 18 knots at 179°. The crosswind component was 13 knots, while the headwind component was also 13 knots. As the aircraft took off, it began its enroute climb, which started 1 mile southwest of KBDL. The climb took the aircraft from an altitude of 1,224 feet above sea level to 10,968 feet above sea level, an increase of 9,745 feet in just 7 minutes, covering a distance of 21 nautical miles.
Following the initial climb, the aircraft entered a level cruise phase, which started 1 mile west of the Westford Airstrip (CT74) in Ashford, Connecticut. This phase lasted for 5 minutes and covered a distance of 34 nautical miles. The aircraft then began its enroute descent, which started 1 mile southeast of Cumberland, Rhode Island. The descent took the aircraft from an altitude of 10,966 feet above sea level to 2,554 feet above sea level, a decrease of 8,413 feet in 7 minutes, covering a distance of 31 nautical miles.
The aircraft then entered another level cruise phase, which started 1 mile north of Hull, Massachusetts. This phase lasted for 3 minutes and covered a distance of 9 nautical miles. The aircraft then began its final descent, which started 1 mile south of Marblehead, Massachusetts. The descent took the aircraft from an altitude of 2,575 feet above sea level to 1,105 feet above sea level, a decrease of 1,470 feet in just 2 minutes, covering a distance of 6 nautical miles.
The final approach to runway 22L at Logan International Airport (KBOS) was made from the north, with the aircraft heading 202.0° at an altitude of 1,082 feet above ground level and a distance of 3 nautical miles from the runway. The landing was made on runway 22L, which had a length of 7,641 feet. The threshold height was good, but the threshold speed was well above the target at 148 knots.
The touchdown point was 517 feet beyond the touchdown zone, and the touchdown speed was 136 knots, which was a little fast. However, the touchdown rate was good at -163 feet per minute. The runway touchdown position was slightly misaligned by 11 feet from the centerline. The local weather conditions at the time of landing were characterized by a temperature of 63°F and winds of 19 knots at 189°. The crosswind component was 3 knots, while the headwind component was 19 knots.
The total landing distance was 4,342 feet, which accounted for 57% of the runway. The runway rollout alignment was perfect. The taxiing period from the runway to the parking took just 3 minutes and covered a distance of less than 1 nautical mile. The total flight distance was 110 nautical miles, and the flight duration was 41 minutes. The aircraft used 3,755 pounds of fuel during the flight.
The Boeing 737-900 aircraft successfully landed at KBOS Logan International Airport on runway 22L, achieving a score of 98.5%. The final approach was initiated from the north, heading 202.0° at a distance of 3 nautical miles and an altitude of 1,082 feet above ground level (agl). The aircraft's approach was characterized by a good threshold height, indicating a stable and controlled descent.
Upon touchdown, the threshold speed was found to be above the target speed of 148 kt, which is a desirable outcome as it suggests a high degree of control and precision during the landing phase. However, the touchdown speed of 136 kt was slightly faster than desired, which may have resulted in a slightly longer landing distance. The touchdown rate of -163 feet per minute (fpm) was deemed good, indicating a smooth and controlled deceleration of the aircraft upon touchdown.
The touchdown point was located 517 feet beyond the touchdown zone, which is a relatively minor deviation. Additionally, the runway touchdown position was slightly misaligned by 11 feet from the centerline, which may have been due to a slight drift or crosswind effect. The local weather conditions at the time of landing were characterized by a temperature of 63°F and a wind speed of 19 kt from 189°, resulting in a 3 kt crosswind and a 19 kt headwind.
The total landing distance of 4,342 feet was 57% of the available runway length of 7,641 feet, which is a relatively short landing distance. The runway rollout alignment was perfect, indicating a high degree of control and precision during the landing phase. Overall, the landing was deemed successful, with the aircraft achieving a high score and demonstrating a high degree of control and precision during the landing phase.
