The Cessna Longitude aircraft successfully landed on runway 17 at KAVL Asheville Regional Airport, but the landing was not without its issues. The aircraft approached the runway from the north, heading 160.0° at 4 nautical miles and 1,244 feet above ground level. The landing was made on a runway with a length of 2,140 meters, and the threshold height was reported as good.
However, there were some concerns with the aircraft's approach and landing performance. The threshold speed was too high at 144 knots, which may have indicated that the pilot was not fully configured for landing. The touchdown distance was good at 397 meters, but the touchdown speed was too fast at 138 knots. This may have resulted in a higher-than-desired touchdown rate of -238 feet per minute, which was only fair.
The runway touchdown position was also excessively misaligned by 122.9 meters from the centerline, which may have been due to the pilot's alignment or the aircraft's directional control during the landing. The local weather conditions at the time of the landing were a temperature of 2°C and winds of 11 knots at 120°, with a crosswind of 7 knots and a headwind of 8 knots.
The total landing distance was 1,256 meters, which was 59% of the runway length. This was a relatively short landing distance, but it may have been influenced by the aircraft's speed and alignment during the landing. The runway rollout alignment was also excessively misaligned by 131.1 meters from the centerline, which may have been due to the pilot's control of the aircraft during the rollout.
Overall, while the Cessna Longitude aircraft successfully landed on runway 17 at KAVL Asheville Regional Airport, there were some issues with the landing performance that need to be addressed. The pilot may need to work on configuring the aircraft for landing at the correct speed and aligning the aircraft with the runway centerline during the approach and landing.
