Flight narrative

The flight began with a departure roll from runway 35 at VTSM Samui Airport, a small airport located on the island of Ko Samui in Thailand. The Boeing 737-800 aircraft took off with a takeoff distance of 995 meters, which was 62% of the runway length. The liftoff speed was 147 knots, and the local weather conditions were characterized by a temperature of 30 degrees Celsius, a wind speed of 7 knots at 25 degrees, resulting in a crosswind of 4 knots and a headwind of 6 knots.

As the aircraft climbed out of VTSM Samui Airport, it began its enroute climb 1 mile north of the airport, at an altitude of 1,018 feet above sea level. The climb was steep, with an increase of 3,985 feet in just 2 minutes, covering a distance of 10 nautical miles. The aircraft then leveled off at an altitude of 5,003 feet above sea level for a brief period of 2 minutes, covering 9 nautical miles.

The aircraft then began another enroute climb, this time from 5,137 feet above sea level to 31,960 feet above sea level, an increase of 26,823 feet in 22 minutes, covering a distance of 151 nautical miles. This climb took the aircraft over the island of Ko Pha Ngan and into the upper levels of the atmosphere.

As the aircraft approached its destination, VTBD Don Mueang International Airport, it began its enroute descent from 31,962 feet above sea level to 1,324 feet above sea level, a decrease of 30,639 feet in 24 minutes, covering a distance of 97 nautical miles. The descent took the aircraft over the coastal region of Thailand, and it eventually lined up for a final approach to runway 21L at VTBD Don Mueang International Airport.

The final approach was made from the north-east, heading 212.0 degrees at 4 nautical miles and 1,307 feet above ground level. The landing was made on runway 21L, which was 3,170 meters long. The threshold height was good, and the threshold speed was slightly above the target speed of 152 knots. The touchdown distance was good at 345 meters, but the touchdown speed was a little fast at 152 knots, resulting in a hard touchdown rate of -412 feet per minute. The runway touchdown alignment was perfect, and the local weather conditions were characterized by a temperature of 23 degrees Celsius, a wind speed of 2 knots at 340 degrees, resulting in a crosswind of 2 knots and a tailwind of 2 knots.

After landing, the aircraft taxied to the parking area from the runway in just 1 minute, covering a distance of less than 1 nautical mile. The total flight distance was 274 nautical miles, and the flight duration was 58 minutes. The aircraft used a total of 2,924 kilograms of fuel during the flight.

Landing Summary

The Boeing 737-800 aircraft successfully landed at VTBD Don Mueang International Airport, achieving a high score of 95.9%. The final approach to runway 21L was initiated from the north east, with a heading of 212.0° at a distance of 4 nautical miles and an altitude of 1,307 feet above ground level (agl). The aircraft's approach was characterized by a good threshold height, indicating a stable and controlled descent.

Upon touchdown, the aircraft's threshold speed was slightly above the target speed of 150 kn, registering at 152 kn. However, the touchdown distance of 345 meters was considered good, indicating a smooth and controlled landing. The touchdown speed of 152 kn was slightly faster than desired, which may have contributed to a harder touchdown rate of -412 feet per minute (fpm). Despite this, the runway touchdown alignment was perfect, demonstrating the pilot's skill and control during the landing.

The local weather conditions at the time of landing were favorable, with a temperature of 23°C and a gentle wind of 2 kn from 340°. This resulted in a negligible crosswind and tailwind component, making the landing even more challenging and impressive. The total landing distance of 2,001 meters, which accounted for 63% of the runway length, was also within acceptable limits.

During the rollout phase, the aircraft's alignment was very good, indicating a smooth and controlled deceleration. Overall, the landing was considered successful, with the aircraft's high score reflecting the pilot's expertise and the aircraft's performance.
