Arrival Rollout — bounce at touchdown; Runway alignment max 6.84 m at 86 %, −0.26 points

Top opportunity

Improve the takeoff

Flight narrative

The flight began with a taxiing period from the parking to the runway, which took 11 minutes and covered a distance of 2 nautical miles. The aircraft, a Cessna CJ4 Citation, then departed from runway 36 at RCKU Chiayi Airport. The takeoff distance was 520 meters, which accounted for 17% of the runway. The liftoff speed was 119 knots.

The local weather conditions at the time of takeoff were characterized by a temperature of 19 degrees Celsius and a wind speed of 11 knots at a direction of 7 degrees. This resulted in a crosswind of 2 knots and a headwind of 11 knots. The aircraft began its enroute climb 1 mile northwest of RCKU Chiayi Airport, Chiayi City, Taiwan. The climb took 7 minutes and covered a distance of 38 nautical miles, during which the aircraft ascended from an altitude of 1,103 feet above sea level to 21,557 feet above sea level, an increase of 20,454 feet.

Following the enroute climb, the aircraft entered a level cruise phase, which started 7 miles southwest of Taichung, Taiwan. This phase lasted for 2 minutes and covered a distance of 15 nautical miles. The enroute descent phase began 6 miles north of RCMQ Taichung International Airport/Ching Chuang Kang Air Base Taichung, Taiwan. The descent took 14 minutes and covered a distance of 62 nautical miles, during which the aircraft descended from an altitude of 21,534 feet above sea level to 1,290 feet above sea level, a decrease of 20,243 feet.

The final approach to runway 10 at RCSS Taipei Songshan Airport was made from the west, with a heading of 92.0 degrees at a distance of 4 nautical miles and an altitude of 1,269 feet above ground level. The landing was made on runway 10, which had a length of 2,600 meters. The threshold height was good, and the threshold speed was slightly below the target at 96 knots. The touchdown distance was good at 376 meters, and the touchdown speed was 84 knots, which was also good. However, the touchdown rate was fair at -262 feet per minute.

The runway touchdown position was slightly misaligned by 6.0 meters from the centerline. The local weather conditions at the time of landing were characterized by a temperature of 16 degrees Celsius and a wind speed of 12 knots at a direction of 100 degrees. This resulted in a crosswind of 2 knots and a headwind of 12 knots. The total landing distance was 969 meters, which accounted for 37% 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 123 nautical miles, and the flight duration was 31 minutes. The aircraft used 691 kilograms of fuel during the flight.

Landing on runway 10 at RCSS Taipei Songshan Airport in the Cessna Citation CJ4
Landing Score 95.27 %
Landing Summary

The Cessna CJ4 Citation successfully landed at RCSS Taipei Songshan Airport, achieving a score of 95.3%. The aircraft approached the runway from the west, heading 92.0° at a distance of 4 nautical miles and an altitude of 1,269 feet above ground level (agl). The pilot executed a precise final approach, taking into account the local weather conditions, which included a temperature of 16°C and a wind speed of 12 knots at 100°.

Upon landing, the aircraft touched down on runway 10, which has a length of 2,600 meters. The threshold height was satisfactory, and the threshold speed was slightly below the target speed of 96 knots. The touchdown distance of 376 meters was considered good, and the touchdown speed of 84 knots was also within acceptable limits. However, the touchdown rate of -262 feet per minute (fpm) was only fair, indicating that the pilot could have achieved a smoother touchdown.

The runway touchdown position was slightly misaligned from the centerline by 6.0 meters, which may have been due to the crosswind or other factors. The local weather conditions, with a headwind of 12 knots and a crosswind of 2 knots, may have contributed to this slight deviation. Despite this, the total landing distance of 969 meters, which accounted for 37% of the runway, was considered acceptable.

The most notable aspect of this landing was the excellent runway rollout alignment, which was described as very good. This suggests that the pilot maintained control of the aircraft during the rollout phase, ensuring a smooth and stable transition from the landing phase to the taxiing phase. Overall, the Cessna CJ4 Citation's landing at RCSS Taipei Songshan Airport was a successful one, with the pilot demonstrating good skills and judgment in executing a precise and controlled landing.
