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 5,000 ft of the approach.
Plan view — the first 5,000 ft of the 8,612 ft runway, to the same scale as the side view.
The 940 ft 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 5 minutes and covered a distance of 1 nautical mile. The aircraft, a Cessna CJ4 Citation, then departed from runway 18 at KTVL Lake Tahoe Airport, with a takeoff distance of 2,471 feet, which was 43% of the runway length. The liftoff speed was 122 knots.
The local weather conditions at the time of departure were characterized by a temperature of 62°F and a wind speed of 1 knot from a direction of 270°. The aircraft experienced a crosswind of 1 knot and a headwind of 0 knots. The enroute climb started overhead KTVL Lake Tahoe Airport, with the aircraft ascending from 7,303 feet above sea level to 19,284 feet above sea level, an increase of 11,981 feet in 4 minutes and covering a distance of 13 nautical miles.
Following the initial climb, the aircraft entered a level cruise phase, which lasted for 2 minutes and covered a distance of 9 nautical miles. This phase started 2 miles south-west of Tahoma, California. The aircraft then began its descent from 19,489 feet above sea level to 16,153 feet above sea level, a decrease of 3,336 feet in 2 minutes and covering a distance of 8 nautical miles. This descent started 6 miles west of Sunnyside-Tahoe City, California.
The aircraft then initiated another climb phase, ascending from 16,159 feet above sea level to 16,825 feet above sea level, an increase of 666 feet in 2 minutes and covering a distance of 7 nautical miles. This climb phase started 13 miles west of Sunnyside-Tahoe City, California. The aircraft then entered another level cruise phase, which lasted for 10 minutes and covered a distance of 40 nautical miles. This phase started 10 miles north-east of Foresthill, California.
The final descent phase began 2 miles east of 25CL Van Dyke Strip Pleasant Grove, California, with the aircraft descending from 16,525 feet above sea level to 1,503 feet above sea level, a decrease of 15,022 feet in 6 minutes and covering a distance of 10 nautical miles. The aircraft then began its final approach to runway 17R at KSMF Sacramento International Airport, heading 194.0° at 4 nautical miles and 1,454 feet above ground level.
The landing on runway 17R was successful, with a touchdown distance of 934 feet and a touchdown speed of 88 knots. The threshold speed was good at 95 knots, and the touchdown rate was fair at -300 feet per minute. However, the runway touchdown position was significantly misaligned by 68 feet from the centreline. The total landing distance was 2,723 feet, which was 32% of the runway length. The runway rollout alignment was also misaligned by 70 feet from the centreline.
The taxiing period from the runway to the parking took 3 minutes and covered a distance of less than 1 nautical mile. The total flight distance was 94 nautical miles, and the flight duration was 37 minutes. The aircraft used 617 pounds of fuel during the flight.
The Cessna CJ4 Citation aircraft successfully landed at KSMF Sacramento International Airport, but with some notable deviations from ideal performance. The final approach was initiated from the north, heading 194.0° at 4 nautical miles and 1,454 feet above ground level (agl). The aircraft maintained a good threshold height, and the threshold speed of 95 knots was also satisfactory.
Upon touchdown, the aircraft performed well in terms of distance, with a touchdown distance of 934 feet being within acceptable limits. The touchdown speed of 88 knots was also good, indicating a controlled descent. However, the touchdown rate of -300 feet per minute (fpm) was only fair, suggesting that the aircraft may have experienced a slightly higher-than-desired rate of descent.
One of the notable issues with this landing was the significant misalignment of the runway touchdown position, which was off-centerline by 68 feet. This could have been due to a variety of factors, including pilot error or a discrepancy in the aircraft's navigation systems. Additionally, the runway rollout alignment was also misaligned by 70 feet from the centreline, which could have contributed to the overall deviation from ideal performance.
The local weather conditions at the time of the landing were relatively calm, with a temperature of 59°F and a wind speed of 1 knot from 270°. This minimal wind made it easier for the aircraft to maintain a stable approach and landing. Overall, while the Cessna CJ4 Citation performed well in terms of distance and speed, the misalignment issues during the landing phase highlight the need for further improvement in terms of navigation and control.
