Maintain the centreline
A small uncorrected heading error at 40 knots becomes a metre of offset per second by 100 knots, noticed only at rotation, producing a crabbed liftoff. Root cause is nearly always eyes on the tape instead of the far end of the runway. Small heading changes displace a distant point visibly long before the nearby centreline stripes look wrong.

The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
One stabilised approach gate: five checks where the approach path is 500 ft above the runway. The 1,000 ft gate was not assessed, because the approach did not join final that far out.
Side view — the last 2,022 m of the approach.
Plan view — the first 2,022 m of the 3,608 m runway, to the same scale as the side view.
The 398 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The flight began with a taxiing period from the parking to the runway, which took 12 minutes and covered a distance of 7 nautical miles. The aircraft, a Cessna CJ4 Citation, then departed from runway 36 at ZGHA Changsha Huanghua International Airport. The takeoff distance was 733 meters, which accounted for 23% of the runway. The liftoff speed was 121 knots, and the local weather conditions were characterized by a temperature of 4°C, a wind speed of 1 knot at 340°, and a crosswind of 0 knots.
As the aircraft climbed out of Changsha, it began its enroute climb, which started 1 mile north of the airport and reached an altitude of 36,595 feet above sea level. This climb phase covered a distance of 43 nautical miles and took 13 minutes. The aircraft then entered a level cruise phase, which lasted 9 minutes and covered 46 nautical miles. This phase started 9 miles southwest of Yutan, China.
The enroute climb phase was followed by a series of level cruise and descent phases. The first descent phase started 28 miles south of ZGCD Changde Taohuayuan Airport and took 4 minutes to descend from 36,559 feet to 30,674 feet. The subsequent level cruise phase lasted 22 minutes and covered 140 nautical miles. The next descent phase started 11 miles west of Enshi, China, and took 4 minutes to descend from 30,377 feet to 26,294 feet.
The flight then entered another level cruise phase, which lasted 4 minutes and covered 28 nautical miles. This was followed by a descent phase that started 24 miles southwest of ZUWX Wanzhou Wuqiao Airport and took 2 minutes to descend from 26,285 feet to 24,457 feet. The subsequent level cruise phase lasted 23 minutes and covered 144 nautical miles.
The flight then entered a series of descent phases, each of which took the aircraft closer to its destination, ZUUU Chengdu Shuangliu International Airport. The first of these descent phases started 24 miles west of Suining, China, and took 11 minutes to descend from 24,192 feet to 5,273 feet. The subsequent level cruise phase lasted 2 minutes and covered 6 nautical miles.
The final descent phase started 3 miles southeast of ZUXJ Wujin Airport and took 4 minutes to descend from 5,155 feet to 2,612 feet. The aircraft then began its final approach to runway 02R at ZUUU Chengdu Shuangliu International Airport, heading 24.0° at 3 nautical miles and 967 feet above ground level.
The landing on runway 02R was successful, with a touchdown speed of 92 knots and a touchdown rate of -126 feet per minute. The touchdown distance was 399 meters, which was good, and the runway touchdown alignment was perfect. The local weather conditions at the time of landing were characterized by a temperature of 6°C, a wind speed of 2 knots at 190°, and a crosswind of 0 knots.
After landing, the aircraft taxied to the parking area, which took 5 minutes and covered a distance of 1 nautical mile. The total flight distance was 551 nautical miles, and the flight took a total of 112 minutes. The aircraft used 598 kilograms of fuel during the flight.
The Cessna CJ4 Citation successfully landed at ZUUU Chengdu Shuangliu International Airport, achieving a score of 96.2%. The aircraft approached the runway from the south, heading 24.0° at 3 nautical miles and 967 feet above ground level (agl). The final approach was executed with precision, and the aircraft landed smoothly on runway 02R, which has a length of 3,608 meters.
The threshold height was good, indicating that the aircraft was at the correct altitude as it approached the runway. However, the threshold speed was slightly below the target speed of 99 knots, which may have been due to the aircraft's descent rate or the pilot's decision to maintain a safe speed. Despite this, the touchdown distance was good at 399 meters, and the touchdown speed of 92 knots was also within acceptable limits.
The touchdown rate was smooth at -126 feet per minute (fpm), indicating that the aircraft touched down without any significant impact or bounce. The runway touchdown alignment was perfect, which is a critical aspect of a safe landing. The local weather conditions at the time of landing were relatively calm, with a temperature of 6°C and a wind speed of 2 knots from 190°. This resulted in a negligible crosswind component and a slight tailwind of 2 knots.
The total landing distance was 1,931 meters, which is 54% of the runway length. This is a relatively short landing distance, indicating that the aircraft was well-controlled and the pilots executed the landing with precision. However, the runway rollout alignment was slightly misaligned by 9.5 meters from the centerline, which may have been due to the aircraft's speed or the pilot's decision to maintain a safe distance from the centerline during rollout. Overall, the landing was successful, and the aircraft came to a stop without any issues.
