Flight narrative

Departing from Incheon International Airport, the Boeing 737-800 began its enroute climb, ascending from 1,095 feet above sea level to 12,287 feet in just 4 minutes, covering a distance of 19 nautical miles. This initial climb phase was a crucial part of the flight, setting the stage for the aircraft's subsequent altitude gains. The climb rate of 11,192 feet in 4 minutes was a notable achievement, demonstrating the aircraft's ability to efficiently gain altitude.

As the flight progressed, the aircraft entered a series of enroute level cruises, interspersed with additional climb phases. One notable climb phase occurred 14 miles northeast of Seosan, where the aircraft ascended from 13,012 feet to 36,258 feet in 14 minutes, covering a distance of 100 nautical miles. This climb phase was followed by a prolonged level cruise, lasting 75 minutes and covering 550 nautical miles. The aircraft's ability to maintain a stable altitude during this phase was a testament to its robust systems and experienced crew.

As the flight entered its final descent phase, the aircraft began its descent from 36,856 feet above sea level to 6,130 feet in 23 minutes, covering a distance of 135 nautical miles. The subsequent level cruise phase, which lasted 10 minutes and covered 45 nautical miles, was followed by a final descent phase, where the aircraft descended from 6,133 feet to 1,306 feet in 7 minutes, covering a distance of 26 nautical miles. The aircraft then began its final approach to runway 10 at Taipei Songshan Airport, landing safely and efficiently, with a total landing distance of 1,804 meters, or 69% of the runway length. The flight's total distance was 894 nautical miles, and it utilized 5,781 kilograms of fuel during its 155-minute duration.

Landing Summary

The Boeing 737-800 touched down on runway 10 at RCSS Taipei Songshan Airport, concluding a final approach from the west. The aircraft's descent was characterized by a slightly high threshold height of 67 feet above ground level, exceeding the target. However, the threshold speed of 138 knots was well within acceptable limits, demonstrating good control and management of the aircraft's energy state.

As the aircraft made contact with the runway, the touchdown speed of 131 knots was slightly above the desired value, resulting in a firm touchdown rate of -360 feet per minute. The touchdown point was located 86 meters beyond the designated touchdown zone, indicating a slight over-run. Furthermore, the runway touchdown position was slightly misaligned by 7 meters from the centerline, although the rollout alignment was very good, showcasing the pilot's ability to maintain control and correct for any deviations.

The total landing distance of 1,804 meters accounted for 69% of the runway length, which is a reasonable figure considering the aircraft's size and the prevailing wind conditions. The local weather was characterized by a temperature of 26 degrees Celsius and a gentle headwind of 5 knots, with a minimal crosswind component of 1 knot. Overall, the landing performance was satisfactory, with a score of 91.7% reflecting the pilots' skill and attention to detail.
