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 6,292 ft runway, to the same scale as the side view.
The 440 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 03R at the Detroit Metropolitan Wayne County Airport, with a takeoff distance of 997 meters, which was 33% of the runway length. The liftoff speed was 137 knots.
As the aircraft climbed away from the airport, it encountered local weather conditions of 9°C temperature and a wind of 13 knots at 89°. The crosswind was 12 knots, and the headwind was 6 knots. The enroute climb started overhead the Detroit Metropolitan Wayne County Airport, with the aircraft ascending from 1,437 feet above sea level to 43,459 feet above sea level, an increase of 42,022 feet in 21 minutes, covering a distance of 75 nautical miles.
The enroute level cruise started 4 miles south of Bellevue, Michigan, and lasted for 7 minutes, covering 32 nautical miles. The aircraft then began its descent from 43,064 feet above sea level to 39,217 feet above sea level, a decrease of 3,847 feet in 5 minutes, covering 27 nautical miles. This was followed by another enroute level cruise, which started 6 miles northwest of South Haven, Michigan, and lasted for 19 minutes, covering 101 nautical miles.
The enroute descent started 2 miles west of the Kirkpatrick Airport in Harvard, Wisconsin, with the aircraft descending from 39,186 feet above sea level to 20,818 feet above sea level, a decrease of 18,368 feet in 14 minutes, covering 59 nautical miles. The aircraft then entered another enroute level cruise, which started 1 mile north of Stockton, Illinois, and lasted for 2 minutes, covering 6 nautical miles.
The enroute descent started 3 miles southeast of Apple Canyon Lake, Illinois, with the aircraft descending from 20,621 feet above sea level to 2,760 feet above sea level, a decrease of 17,861 feet in 8 minutes, covering 32 nautical miles. The aircraft then entered another enroute level cruise, which started 1 mile west of Delmar, Iowa, and lasted for 6 minutes, covering 13 nautical miles.
The final enroute descent started 5 miles south of the Kleis Airport in Zwingle, Iowa, with the aircraft descending from 2,602 feet above sea level to 1,521 feet above sea level, a decrease of 1,081 feet in 3 minutes, covering 7 nautical miles. The aircraft then began its final approach to runway 36 at the Dubuque Regional Airport, flying from the south at a heading of 360.0°, 4 nautical miles from the airport, and 446 feet above ground level.
The landing on runway 36 at the Dubuque Regional Airport was completed with a touchdown distance of 132 meters, which was good. However, the touchdown speed of 124 knots was excessively fast, and the touchdown rate of -187 feet per minute was good. The runway touchdown position was significantly misaligned by 18.2 meters from the centerline. The local weather conditions at the time of landing were 8°C temperature and a wind of 11 knots at 70°, with a crosswind of 10 knots and a headwind of 4 knots.
The total landing distance was 1,319 meters, which was 69% of the runway length. The runway rollout alignment was misaligned by 24.1 meters from the centerline. The taxiing period from the runway to the parking took 5 minutes and covered less than 1 nautical mile. The total flight distance was 360 nautical
The Cessna CJ4 Citation aircraft successfully landed at KDBQ Dubuque Regional Airport, but with some notable areas for improvement. The final approach was conducted from the south, heading 360.0° at 4 nautical miles and 446 feet above ground level (agl). The aircraft touched down on runway 36, which has a length of 1,918 meters.
The threshold height was satisfactory, but the threshold speed was excessively high at 126 knots. This indicates that the pilot may have been able to flare the aircraft more effectively to reduce the touchdown speed. The touchdown distance was good at 132 meters, but the touchdown speed was also excessively fast at 124 knots. A faster touchdown speed can increase the risk of a hard landing or damage to the aircraft.
The touchdown rate was good at -187 feet per minute (fpm), which suggests that the pilot was able to control the descent effectively. However, the runway touchdown position was significantly misaligned by 18.2 meters from the centreline. This may have been due to a combination of factors, including wind, pilot error, or a navigation issue.
The local weather conditions at the time of the landing were a temperature of 8°C and a wind of 11 knots at 70°. The crosswind component was 10 knots, while the headwind component was 4 knots. These conditions may have contributed to the misaligned touchdown position.
The total landing distance was 1,319 meters, which is 69% of the runway length. This is a relatively short landing distance, but it may have been influenced by the misaligned touchdown position. The runway rollout alignment was also misaligned by 24.1 meters from the centreline, which may have been due to the same factors that contributed to the initial touchdown position.
Overall, while the landing was successful, there are several areas for improvement, including reducing the threshold speed and touchdown speed, and improving the alignment of the touchdown position and runway rollout.
