Slow the descent speed
Below 10,000 ft you are typically limited to 250 kt indicated (a US rule that much of the world mirrors in some form, though not universally). This forces a deceleration around 10,000 ft whether the profile wants one or not, so plan for it rather than discovering it.

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.
The approach, gate by gate
Side view — the last 1,524 m of the approach.
Plan view — the first 1,524 m of the 2,295 m runway, to the same scale as the side view.
The 468 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
Aer Lingus flight EI-NSD, an Airbus A321-251N, began its journey from Luis Munoz Marin International Airport (TJSJ) in San Juan, Puerto Rico. The aircraft taxied from the parking area to the runway, taking 10 minutes and covering a distance of 3 nautical miles. Departure roll took place on runway 08, with the takeoff distance being 1,311 meters, which is 45% of the runway length. The aircraft lifted off at a speed of 152 knots.
As the aircraft climbed to its cruising altitude, it encountered local weather conditions of 35°C temperature and a wind speed of 14 knots at 70°. The crosswind was minimal at 1 knot, while the headwind was 14 knots. The enroute climb started 1 mile northeast of TJSJ and took the aircraft from 1,038 feet above sea level to 24,008 feet, an increase of 22,969 feet in 9 minutes, covering a distance of 50 nautical miles.
The enroute level cruise began 19 miles northwest of Cyril E. King Airport (TIST) in Charlotte Amalie, Saint Thomas Island, and lasted for 9 minutes, covering a distance of 58 nautical miles. The aircraft then started its enroute descent 18 miles east of Virgin Gorda Airport (TUPW) in Spanish Town, British Virgin Islands. The descent took the aircraft from 23,582 feet to 1,276 feet, a decrease of 22,305 feet in 13 minutes, covering a distance of 58 nautical miles.
The final approach to runway 10 at Princess Juliana International Airport (TNCM) was made from the west, heading 81.0° at 4 nautical miles and 1,251 feet above ground level. The aircraft landed on runway 10, which has a length of 2,295 meters. The threshold height was good, and the threshold speed of 123 knots was well below the target, requiring the pilots to be cautious not to stall. The touchdown distance was good at 466 meters, and the touchdown speed of 120 knots was also good. The touchdown rate was firm at -335 feet per minute.
The runway touchdown position was slightly misaligned by 5.2 meters from the centerline. The local weather conditions at the time of landing were 30°C temperature and a wind speed of 12 knots at 50°. The crosswind was 6 knots, while the headwind was 10 knots. The total landing distance was 1,256 meters, which is 55% of the runway length. The runway rollout alignment was very good.
After landing, the aircraft taxied to the parking area, taking 2 minutes and covering less than 1 nautical mile. The total flight distance was 174 nautical miles, and the flight duration was 45 minutes. The aircraft used 1,929 kilograms of fuel during the flight.
Aer Lingus flight EI-NSD, an Airbus A321-251N, successfully landed at Princess Juliana International Airport (TNCM) with a score of 94.8%. The aircraft approached the runway from the west, heading 81.0° at a distance of 4 nautical miles and an altitude of 1,251 feet above ground level (agl).
The final approach to runway 10 was executed with precision, and the aircraft touched down on the runway with a good touchdown distance of 466 meters. The touchdown speed of 120 knots was also within the acceptable range, indicating a smooth and controlled descent. However, the touchdown rate of -335 feet per minute (fpm) was slightly firm, suggesting that the pilots may have applied a bit more braking than necessary.
One notable aspect of the landing was the slight misalignment of the runway touchdown position, which was 5.2 meters off the centerline. This may have been due to a slight deviation in the aircraft's alignment during the final approach or a minor error in the pilots' navigation. Nevertheless, the runway rollout alignment was very good, indicating that the pilots were able to quickly regain control of the aircraft and align it with the runway centerline.
The local weather conditions at the time of the landing were favorable, with a temperature of 30°C and a moderate wind of 12 knots at 50°. The crosswind component was relatively light at 6 knots, while the headwind component was 10 knots, which may have helped to reduce the aircraft's ground speed and make the landing more manageable.
Overall, the landing was executed with a high degree of precision and control, and the pilots were able to bring the aircraft to a safe stop within a relatively short distance of 1,256 meters, which is approximately 55% of the runway length.
