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 1,795 m of the approach.
Plan view — the first 1,795 m of the 3,201 m runway, to the same scale as the side view.
The 344 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 18 minutes and covered a distance of 5 nautical miles. The aircraft, a Cessna CJ4 Citation, then departed from runway 08 at ZBHH Hohhot Baita International Airport in Hohhot, Inner Mongolia Autonomous Region, China. The takeoff distance was 788 meters, which accounted for 22% of the runway. The liftoff speed was 122 knots.
The local weather conditions at the time of departure were characterized by a temperature of -5°C, with a wind speed of 3 knots at a direction of 50°. This resulted in a crosswind of 1 knot and a headwind of 3 knots. The aircraft then began its enroute climb, starting 1 mile east of the airport and rising from an altitude of 4,603 feet above sea level to 31,678 feet above sea level, an increase of 27,074 feet in 10 minutes. The climb covered a distance of 57 nautical miles.
Following the climb, the aircraft entered a level cruise phase, which started 1 mile southwest of ZBUC Ulanqab Jining Airport in Ulanqab, Inner Mongolia Autonomous Region, China. This phase lasted for 47 minutes and covered a distance of 222 nautical miles. The aircraft then began its enroute descent, starting 9 miles north of ZBTJ Tianjin Binhai International Airport in Tianjin, Tianjin Shi, China. The descent took 22 minutes and covered a distance of 5 nautical miles, during which the aircraft dropped from an altitude of 31,779 feet above sea level to 1,274 feet above sea level, a decrease of 30,504 feet.
The final approach to runway 16L at ZBTJ Tianjin Binhai International Airport was made from the northwest, with a heading of 154.0° at an altitude of 1,252 feet above ground level and a distance of 4 nautical miles from the runway. The landing was made on runway 16L, which had a length of 3,201 meters. The threshold height was good, and the threshold speed was slightly below the target at 98 knots.
The touchdown distance was good at 344 meters, and the touchdown speed was 88 knots, which was also good. The touchdown rate was smooth at -122 feet per minute. However, the runway touchdown position was misaligned by 9.2 meters from the centerline. The local weather conditions at the time of landing were characterized by a temperature of 4°C, with a wind speed of 3 knots at a direction of 260°. This resulted in a crosswind of 3 knots and a tailwind of 1 knot.
The total landing distance was 1,697 meters, which accounted for 53% of the runway. The runway rollout alignment was slightly misaligned by 10.5 meters from the centerline. The taxiing period from the runway to the parking took 17 minutes and covered a distance of 1 nautical mile. The total flight distance was 296 nautical miles, and the flight duration was 85 minutes. The aircraft used 853 kilograms of fuel during the flight.
The Cessna CJ4 Citation aircraft successfully landed at ZBTJ Tianjin Binhai International Airport, achieving a score of 94.7%. The final approach to runway 16L was initiated from the north-west, with a heading of 154.0° at a distance of 4 nautical miles and an altitude of 1,252 feet above ground level.
The aircraft touched down on the runway with a speed of 98 knots, which was slightly below the target threshold speed. However, the touchdown distance of 344 meters was considered good, and the touchdown speed of 88 knots was also within acceptable limits. The touchdown rate was smooth, with a descent rate of -122 feet per minute.
Despite the good performance in terms of speed and distance, there were some minor issues with the landing. The runway touchdown position was misaligned by 9.2 meters from the centreline, and the runway rollout alignment was also slightly off-centre by 10.5 meters. However, these deviations were not significant enough to impact the overall safety of the landing.
The local weather conditions at the time of the landing were relatively calm, with a temperature of 4°C and a wind speed of 3 knots from a direction of 260°. The crosswind component was 3 knots, while the tailwind component was 1 knot. These conditions were not considered to be a significant factor in the landing.
Overall, the Cessna CJ4 Citation aircraft performed well during the landing, with a good score of 94.7%. While there were some minor issues with alignment, the aircraft's speed and distance performance were within acceptable limits, and the touchdown rate was smooth.
