Landing on runway 27C at KORD Chicago O'Hare International Airport in the A21N

Landing Score 99.65 %

Landing Summary

The aircraft, identified as A21N, successfully landed on runway 27C at KORD Chicago O'Hare International Airport with a high score of 99.7%. The final approach was conducted from the east, heading 270.0° at a distance of 1 nautical mile and an altitude of 1,984 feet above ground level (agl). The aircraft's approach and landing performance were satisfactory, with a good threshold height and a threshold speed of 136 knots.

Upon touchdown, the aircraft demonstrated a good landing distance of 1,189 feet, which is within the acceptable range for the runway length of 10,619 feet. The touchdown speed of 128 knots was also within the desired parameters, indicating a smooth and controlled descent. The touchdown rate of -73 feet per minute (fpm) was excellent, signifying a gentle and stable landing.

However, there was a slight deviation in the runway touchdown position, with the aircraft being 11 feet off the centerline. This minor misalignment did not significantly impact the overall landing performance. The local weather conditions at the time of landing were favorable, with a temperature of 3°F and a wind speed of 0 knots from 0°. This resulted in a negligible crosswind and headwind, allowing the aircraft to maintain a stable approach and landing.

The total landing distance of 2,400 feet was 23% of the runway length, which is within the acceptable range. The runway rollout alignment was perfect, indicating that the aircraft's brakes were applied smoothly and effectively, allowing for a controlled deceleration. Overall, the landing performance of the A21N aircraft was satisfactory, with a high score and minimal deviations from the desired parameters.
