Landing on runway 09 at LBSF Sofia Airport in the Boeing 737-MAX8

Landing Score 85.81 %

Landing Summary

The Boeing 737-MAX8 aircraft successfully landed at LBSF Sofia Airport, achieving an overall score of 85.8%. The final approach to runway 09 was initiated from the west, with a heading of 94.0° at 2 nautical miles and 720 feet above ground level (agl). The aircraft successfully touched down on the runway, which has a length of 3,588 meters.

The threshold height at 73 feet agl was well above the target, indicating a safe margin for the aircraft to descend and touch down. However, the threshold speed was slightly below the target at 131 knots, which may have required some additional control input from the pilots to maintain a stable approach. The touchdown point was 435 meters beyond the touchdown zone, which is a relatively long distance but still within the runway's length.

The touchdown speed of 127 knots was good, indicating that the pilots maintained a stable approach and managed to slow the aircraft down effectively. However, the touchdown rate of -241 feet per minute (fpm) was only fair, suggesting that the aircraft may have experienced some deceleration issues during the landing. The runway touchdown alignment was very good, indicating that the pilots maintained a stable and aligned approach.

The local weather conditions at the time of landing were favorable, with a temperature of 24°C and a wind speed of 11 knots at 319°. The crosswind and tailwind components were both 8 knots, which may have required some additional control input from the pilots to maintain a stable approach. The total landing distance of 2,004 meters was 56% of the runway length, which is a relatively long distance but still within the acceptable range.

During the rollout, the aircraft's alignment was slightly misaligned by 8.2 meters from the centerline, which may have required some additional control input from the pilots to maintain a stable rollout. Overall, the landing was successful, but there were some areas for improvement, particularly in terms of touchdown rate and rollout alignment.
