Fixing the bounce
Fast at the threshold, normal flare, and the runway seems to refuse the aircraft. The instinctive fix - pushing it on - causes the next one. A fast aircraft forced onto the runway touches nosewheel-first or nearly so. The tell is a touchdown that feels soft followed by a bounce that steepens. Pilots fix the bounce recovery; the cause was the 10 knots at the threshold.

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 8,617 ft runway, to the same scale as the side view.
The 1,219 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 less than 1 nautical mile. The aircraft, a Cessna CJ4 Citation, then departed from runway 36 at KTVL Lake Tahoe Airport. The takeoff distance was 2,030 feet, which accounted for 36% of the runway. The liftoff speed was 118 knots.
The local weather conditions at the time of departure were characterized by a temperature of 63°F and a wind speed of 1 knot from 270°. The crosswind was 1 knot, while the headwind was 0 knots. The aircraft then began its enroute climb, starting 1 mile south of South Lake Tahoe, California. The climb took the aircraft from 7,281 feet above sea level to 14,836 feet above sea level, an increase of 7,554 feet in just 2 minutes, covering a distance of 7 nautical miles.
Following the initial climb, the aircraft entered a level cruise phase, starting 3 miles west of Lakeridge, Nevada. This phase lasted for 2 minutes and covered a distance of 9 nautical miles. The aircraft then began another climb, this time from 14,468 feet above sea level to 17,009 feet above sea level, an increase of 2,541 feet in 3 minutes, covering a distance of 5 nautical miles. The climb started 2 miles southwest of Sunnyside-Tahoe City, California.
The aircraft then entered another level cruise phase, starting 6 miles west of T38 Homewood Lake Tahoe, California. This phase lasted for 16 minutes and covered a distance of 49 nautical miles. The aircraft then began its descent, starting 1 mile southwest of Folsom, California. The descent took the aircraft from 16,999 feet above sea level to 4,787 feet above sea level, a decrease of 12,212 feet in 5 minutes, covering a distance of 18 nautical miles.
The aircraft then entered another level cruise phase, starting 2 miles southeast of KSMF Sacramento International Airport, Sacramento, California. This phase lasted for 5 minutes and covered a distance of 13 nautical miles. The aircraft then began its final descent, starting 1 mile northeast of 59CN James Brothers Airport Pleasant Grove, California. The descent took the aircraft from 4,761 feet above sea level to 1,878 feet above sea level, a decrease of 2,883 feet in 3 minutes, covering a distance of 7 nautical miles.
The final approach to runway 17L at KSMF Sacramento International Airport was made from the north, heading 181.0° at 2 nautical miles and 1,760 feet above ground level. The landing on runway 17L was characterized by a touchdown point that was 1,402 feet beyond the touchdown zone. The touchdown speed was 112 knots, which was too fast, and the touchdown rate was heavy at -668 feet per minute. The runway touchdown position was slightly misaligned by 14 feet from the centreline.
The local weather conditions at the time of landing were characterized by a temperature of 61°F and a wind speed of 1 knot from 270°. The crosswind was 1 knot, while the headwind was 0 knots. The total landing distance was 3,734 feet, which accounted for 43% of the runway. The runway rollout alignment was slightly misaligned by 28 feet from the centreline.
The taxiing period from the runway to the parking took 4 minutes and covered less than 1 nautical mile. The total flight distance was 113 nautical miles, taking 44 minutes, and the aircraft used 916 pounds of fuel.
The Cessna CJ4 Citation aircraft successfully landed at KSMF Sacramento International Airport, but the landing was not without its issues. The final approach to runway 17L from the north was initiated at a heading of 181.0°, 2 nautical miles away from the runway, and at an altitude of 1,760 feet above ground level (agl).
The aircraft touched down 1,402 feet beyond the touchdown zone, which is a significant deviation from the target. The touchdown speed of 112 knots was also too high, indicating that the pilot may have been unable to slow the aircraft down sufficiently before touchdown. Furthermore, the touchdown rate of -668 feet per minute (fpm) was considered heavy, suggesting that the aircraft may have been subjected to excessive deceleration forces upon landing.
In addition to these issues, the runway touchdown position was slightly misaligned by 14 feet from the centreline, which may have contributed to the overall performance of the landing. The local weather conditions at the time of the landing were relatively calm, with a temperature of 61°F and a wind speed of 1 knot from 270°. This suggests that wind was not a significant factor in the landing.
The total landing distance of 3,734 feet was 43% of the available runway length, which is a relatively high percentage. This may indicate that the pilot was unable to slow the aircraft down sufficiently before touchdown, resulting in a longer than necessary landing distance. The runway rollout alignment was also slightly misaligned by 28 feet from the centreline, which may have contributed to the overall performance of the landing.
Overall, while the Cessna CJ4 Citation aircraft successfully landed at KSMF Sacramento International Airport, the landing was not without its issues. The pilot may have benefited from additional training or practice to improve their ability to slow the aircraft down sufficiently before touchdown and to maintain a more accurate alignment with the runway centreline.
