Flight narrative

The flight began with a taxiing period from the parking to the runway, which took 4 minutes and covered a distance of 1 nautical mile. The aircraft, a Boeing 737-900, then departed from runway 31 at OPDB Dalbandin Airport. The takeoff distance was 1,848 meters, which accounted for 92% of the runway. The liftoff speed was 159 knots.

The local weather conditions at the time of departure were characterized by a temperature of 15 degrees Celsius, with a wind speed of 6 knots at 183 degrees. This resulted in a crosswind of 5 knots and a tailwind of 3 knots. The aircraft then began its enroute climb, starting 1 mile west of Dalbandin, and climbed from an altitude of 3,779 feet above sea level to 36,997 feet above sea level, an increase of 33,218 feet, in 41 minutes and covering a distance of 328 nautical miles.

Following the enroute climb, the aircraft entered a level cruise phase, starting 1 mile north of OP13 Mad Jamu Airport in the Punjab Province of Pakistan. This phase lasted for 245 minutes and covered a distance of 2,067 nautical miles. The aircraft then began its enroute descent, starting 23 miles northwest of VVDH Dong Hoi in Vietnam, and descended from an altitude of 36,482 feet above sea level to 2,917 feet above sea level, a decrease of 33,565 feet, in 23 minutes and covering a distance of 149 nautical miles.

The aircraft then entered another level cruise phase, starting 10 miles southwest of VVDN Da Nang International Airport in Vietnam, and lasted for 5 minutes, covering a distance of 9 nautical miles. The final approach to runway 35R at VVDN Da Nang International Airport was made from the south, with a heading of 352.0 degrees at 4 nautical miles and 1,289 feet above ground level.

The landing on runway 35R was successful, with a touchdown point 82 meters beyond the touchdown zone. The touchdown speed was 129 knots, which was good, and the touchdown rate was smooth at -102 feet per minute. However, the runway touchdown position was slightly misaligned by 6.6 meters from the centerline. The local weather conditions at the time of landing were characterized by a temperature of 23 degrees Celsius, with a wind speed of 2 knots at 100 degrees. This resulted in a crosswind of 2 knots and a tailwind of 1 knot.

The total landing distance was 1,024 meters, which accounted for 29% of the runway. The runway rollout alignment was very good. The taxiing period from the runway to the parking took 2 minutes and covered a distance of less than 1 nautical mile. The total flight distance was 2,561 nautical miles, taking 322 minutes, and the aircraft used 15,700 kilograms of fuel.

Landing Score 98.15 %
Landing Summary

The Boeing 737-900 aircraft successfully landed at VVDN Da Nang International Airport, achieving a high score of 98.2%. The final approach to runway 35R was conducted from the south, with a heading of 352.0° at a distance of 4 nautical miles and an altitude of 1,289 feet above ground level.

The aircraft touched down on the runway with a good threshold height, and the threshold speed was also satisfactory at 134 knots. The touchdown point was located 82 meters beyond the designated touchdown zone, which is a relatively minor deviation. The touchdown speed of 129 knots was within the acceptable range, and the touchdown rate was smooth at -102 feet per minute, indicating a controlled descent.

Despite the minor deviation from the centerline, the runway touchdown position was only slightly misaligned by 6.6 meters. The local weather conditions were favorable, with a temperature of 23°C and a gentle wind of 2 knots at 100°. The crosswind component was minimal at 2 knots, and the tailwind component was even weaker at 1 knot.

The total landing distance of 1,024 meters was 29% of the runway length, which is a relatively short distance considering the aircraft's size and weight. The runway rollout alignment was excellent, indicating that the aircraft's brakes were applied smoothly and effectively, allowing for a stable and controlled deceleration.

Overall, the landing was executed well, with the aircraft touching down safely and smoothly on the runway. The minor deviations from the centerline and the touchdown zone were not significant enough to impact the overall safety of the landing.
