Keep the approach speed on target
Every knot above Vref is stored kinetic energy, and energy stored at the threshold must be dissipated in ground effect before the aeroplane will stop flying. Because kinetic energy scales with the square of speed, the excess you must dissipate grows fast. At a 45-knot approach, five knots hot is over a tenth more speed and roughly a quarter more energy to get rid of in ground effect. This is why the fix is never in the flare. It was decided three miles earlier, on final, at the airspeed indicator.

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.
The approach, gate by gate
Side view — the last 5,000 ft of the approach.
Plan view — the first 5,000 ft of the 5,470 ft runway, to the same scale as the side view.
Touched down 1,699 ft past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The flight began with a short taxiing period from the parking area to the runway, taking approximately 1 minute and covering less than 1 nautical mile. The aircraft, a Cessna CJ4 Citation, then departed from runway 08 at the Griffith-Merrillville Airport (05C), with a takeoff distance of 1,696 feet, which was 45% of the runway length. The liftoff speed was 141 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 269°. This resulted in a crosswind of 0 knots and a tailwind of 1 knot. The aircraft began its enroute climb overhead the Griffith-Merrillville Airport, rising from an altitude of 1,668 feet above sea level to 7,512 feet above sea level, an increase of 5,844 feet, in just 4 minutes and covering a distance of 7 nautical miles.
The enroute level cruise started 1 mile south-west of Dyer, Indiana, and lasted for 3 minutes, covering a distance of 14 nautical miles. The aircraft then began its enroute descent 1 mile west of Frankfort, Illinois, descending from 7,504 feet above sea level to 3,153 feet above sea level, a decrease of 4,351 feet, in 5 minutes and covering a distance of 18 nautical miles.
The enroute level cruise was restarted 1 mile north-west of the 87IL Bushby RLA Restricted Landing Area in Minooka, Illinois, and lasted for 4 minutes, covering a distance of 12 nautical miles. The final approach to runway 33 at the Aurora Municipal Airport (KARR) was made from the south-east, with a heading of 327.0°, at a distance of 4 nautical miles and an altitude of 1,258 feet above ground level.
The landing on runway 33 was characterized by a touchdown point that was 1,129 feet beyond the touchdown zone, with a touchdown speed of 109 knots, which was too fast. The touchdown rate was fair at -224 feet per minute, and the runway touchdown position was misaligned by 34 feet from the centreline. The local weather conditions at the time of landing were similar to those at departure, with a temperature of 62°F and a wind speed of 1 knot from a direction of 270°, resulting in a crosswind of 1 knot and a headwind of 1 knot.
The total landing distance was 3,601 feet, which was 66% of the runway length. The runway rollout alignment was slightly misaligned by 40 feet from the centreline. The taxiing period from the runway to the parking area took approximately 3 minutes and covered less than 1 nautical mile. The total flight distance was 58 nautical miles, taking 24 minutes, and the aircraft used 0 pounds of fuel.
The Cessna CJ4 Citation aircraft successfully landed at KARR Aurora Municipal Airport, but the landing was not without its issues. The aircraft scored 87.4% on its landing, indicating a decent performance but room for improvement. The final approach to runway 33 was initiated from the southeast, heading 327.0° at 4 nautical miles and 1,258 feet above ground level (agl).
Upon landing, the aircraft touched down 1,129 feet beyond the touchdown zone, which is a significant deviation from the ideal touchdown point. The touchdown speed of 109 kt was also too fast, indicating that the pilot may have been unable to slow the aircraft down sufficiently before touchdown. The touchdown rate of -224 fpm was fair, but not exceptional.
One of the major concerns with this landing was the threshold speed, which was excessively high at 126 kt. This suggests that the pilot may have been unable to maintain a stable approach speed, leading to a higher-than-ideal touchdown speed. Additionally, the runway touchdown position was misaligned by 34 feet from the centreline, which could have contributed to the aircraft's deviation from the ideal touchdown point.
The local weather conditions at the time of the landing were relatively calm, with a temperature of 62°F and a wind speed of 1 kt from 270°. This suggests that the wind was not a significant factor in the landing, and the pilot should have been able to maintain a stable approach despite the slight headwind.
The total landing distance of 3,601 feet was 66% of the runway length, which is a relatively high percentage. This suggests that the pilot may have been unable to slow the aircraft down sufficiently before touchdown, leading to a longer-than-ideal landing distance. The runway rollout alignment was also slightly misaligned by 40 feet from the centreline, which could have contributed to the aircraft's deviation from the ideal touchdown point.
Overall, while the Cessna CJ4 Citation aircraft successfully landed at KARR Aurora Municipal Airport, there are several areas for improvement. The pilot should focus on maintaining a stable approach speed, slowing the aircraft down sufficiently before touchdown, and aligning the aircraft with the centreline of the runway. With practice and attention to these areas, the pilot should be able to achieve a higher landing score and improve the overall performance of the aircraft.
