Arrival Landing — Flare profile at 0 %, Threshold height at 69 ft agl was above target at 68 %, −1.37 points

Next time

Departure

Ease back pressure in smoothly as you approach 154 kt, holding a steady rotation rate rather than snatching the controls.

What happened: On the takeoff roll the aircraft bounced before becoming fully airborne.

Watch for: Attitude indicator: a smooth, continuous pitch-up through liftoff with no secondary bounce.

See Departure Roll

Arrival

Fly the flare as one continuous check of the sink rate from 45 ft, holding back pressure steadily rather than adjusting pitch piecemeal.

What happened: The flare drifted away from its intended profile rather than tracking it smoothly from 45 ft down to touchdown.

Watch for: Watch radio altitude and VSI through the flare, aiming to arrest the sink smoothly from 45 ft to touchdown.

See Arrival Landing

Arrive slow and the sink rate at the threshold is already above schedule, the flare is short because there is no energy to extend it, and the touchdown is hard in a way that feels exactly like a late flare. Diagnosing a slow arrival as a late flare is the catastrophic misread: you respond by flaring earlier, which bleeds more speed, which makes the next one worse. The tiebreaker is threshold speed against VRef, not feel. Never diagnose a flare without it.

The flight began with a taxiing period from the parking to the runway, which took 8 minutes and covered a distance of 5 nautical miles. The aircraft, a Boeing 777-200ER, then departed from runway 16L at Seattle-Tacoma International Airport (KSEA). The takeoff distance was 1,459 meters, which was 40% of the runway length. The liftoff speed was 170 knots, and the local weather conditions were characterized by a temperature of 16°C, a wind speed of 7 knots at 199°, with a crosswind of 2 knots and a headwind of 7 knots.

As the aircraft climbed to its initial cruising altitude, it began its enroute climb from 1,349 feet above sea level (asl) to 34,193 ft asl, an increase of 32,844 feet in 21 minutes, covering a distance of 135 nautical miles. The enroute level cruise started 15 miles northeast of Bamfield, British Columbia, Canada, and lasted for 126 minutes, covering a distance of 956 nautical miles.

The aircraft then underwent several enroute climbs and level cruises, each with varying altitudes and durations. The climbs were characterized by rapid increases in altitude, with the aircraft reaching altitudes of up to 41,754 ft asl. The level cruises were marked by steady speeds and altitudes, with the aircraft maintaining a consistent pace for extended periods.

As the aircraft approached its destination, it began its descent from 41,146 ft asl to 1,495 ft asl, a decrease of 39,651 feet in 27 minutes, covering a distance of 132 nautical miles. The final approach to runway 23L at Taiwan Taoyuan International Airport (RCTP) was made from the northeast, with the aircraft heading 228.0° at 4 nautical miles and 1,406 feet above ground level (agl).

The landing on runway 23L was successful, with the touchdown point being 224 meters beyond the touchdown zone. The touchdown speed was 110 knots, which was good, and the touchdown rate was also good at -162 feet per minute (fpm). However, the runway touchdown position was slightly misaligned by 3.1 meters from the centerline. The local weather conditions at the time of landing were characterized by a temperature of 33°C, a wind speed of 17 knots at 290°, with a crosswind of 15 knots and a headwind of 8 knots.

The total landing distance was 1,525 meters, which was 46% of the runway length. The runway rollout alignment was very good, indicating a smooth and controlled landing. The taxiing period from the runway to the parking took 3 minutes and covered a distance of less than 1 nautical mile.

Landing Summary

The Boeing 777-200ER aircraft successfully landed at RCTP Taiwan Taoyuan International Airport on runway 23L. The final approach was initiated from the north east, heading 228.0° at a distance of 4 nautical miles and an altitude of 1,406 feet above ground level (agl). The aircraft's performance during the landing was satisfactory, with a touchdown speed of 110 knots, which was within the acceptable range.

However, there were a few areas where the landing could be improved. The threshold height at 69 feet agl was above the target, indicating that the aircraft was slightly higher than desired when reaching the runway threshold. Additionally, the threshold speed was slightly below the target at 120 knots, suggesting that the aircraft could have been slightly faster when reaching the threshold.

The touchdown point was 224 meters beyond the touchdown zone, which is a relatively minor deviation. The touchdown rate of -162 feet per minute (fpm) was good, indicating that the aircraft was able to touch down smoothly and maintain a stable descent rate.

The runway touchdown position was slightly misaligned by 3.1 meters from the centerline, which may require some adjustments to the aircraft's alignment during the approach. The local weather conditions at the time of landing were hot, with a temperature of 33°C, and a moderate wind of 17 knots at 290°. The crosswind component was 15 knots, while the headwind component was 8 knots.

The total landing distance of 1,525 meters was 46% of the runway length, which is a relatively short distance considering the aircraft's size and weight. The runway rollout alignment was very good, indicating that the aircraft was able to maintain a stable and aligned path during the rollout phase.

Overall, the landing was satisfactory, with some minor areas for improvement. The aircraft's performance during the landing was good, and the crew was able to maintain a stable and controlled descent.
