Landing on runway 19C at KIAD Washington Dulles International Airport in the Boeing 737-800

Landing Score 91.81 %

Landing Summary

During the final approach to runway 19C at KIAD, the Boeing 737-800 was established on a heading of 180.0° at 4 NM from the threshold and descended to 1,222 ft AGL. Ambient conditions were 75 °F with a wind from 266° at 5 kt, producing a 5-kt crosswind and no headwind, and the aircraft maintained a good threshold height.

At the threshold the aircraft’s speed was recorded at 155 kt, which was slightly above the target speed.

Touchdown occurred 458 ft down the runway, with a touchdown speed of 153 kt that was a little fast and a heavy descent rate of minus 690 fpm. The touchdown point was misaligned by 27 ft from the centreline, and the total landing distance measured 4,721 ft, representing 41 % of the 11,499-ft runway.

Rollout alignment was very good, and the aircraft remained well aligned with the runway centreline throughout the rollout.

To refine the performance, focus on moderating the flare to achieve a lighter touchdown rate and adjust the approach speed to meet the target, which will also help reduce the slight excess speed at touchdown. Maintaining precise alignment during flare will further minimize the 27-ft centreline offset.
