Approach & flare

Threshold height

Good threshold height.

Threshold speed

100 %

Threshold speed was good at 143 kt.

Flare

71.65 %

The flare wandered off the target profile. The aircraft floated down the runway before touching. Touchdown was 813 m past the threshold. Threshold speed was not the cause here - hold the aim point on the approach and let the aircraft settle rather than holding it off, and the touchdown comes back to the numbers.

Landing on runway 22L at KMDW Chicago Midway International Airport in the Boeing 737-800

Landing Score 91.6 %

Landing Summary

The Boeing 737-800 approached runway 22L at KMDW from the north-east on a heading of 233.0° at 4 nm and 1,369 ft agl, with temperature 26 °C, wind 13 kt from 150°, a 12 kt cross-wind component and a 4 kt head-wind component. The final approach was assessed as unstable at the 1,000 ft gate: sink rate too high, off the centreline.

At threshold the aircraft maintained a good height and achieved a good threshold speed of 143 kt during the flare.

Touchdown occurred 398 m beyond the touchdown zone with a good speed of 128 kt and a good vertical rate of minus 193 fpm. The touchdown point was misaligned by 7.9 m from the centreline, and the total landing distance was 1,244 m, representing 70 % of the runway length.

Runway rollout alignment was very good.

Focus on establishing a stabilized approach by controlling sink rate and maintaining centreline alignment before the 1,000 ft gate, and aim to place the main gear within the touchdown zone and centred on the runway to reduce the 7.9 m lateral deviation.
