Shorten the long landing
Ground effect becomes significant below about one wingspan of height. A Cessna 172, with a 36 ft span, enters ground effect at flare height - the float it feels in the hold-off is ground effect arriving on cue. An A320, with a span around 117 ft, has been in ground effect since before the threshold and there is no sudden cushion to feel, only a gradual reduction in induced drag that lengthens any float you allow.

The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
Two stabilised approach gates, each with seven checks, where the approach path is 1,000 ft and 500 ft above the runway.
At the 1,000 ft gate: speed above the reference speed.
At the 500 ft gate: speed above the reference speed.
The approach, gate by gate
Side view — the last 5,000 ft of the approach.
Plan view — the first 5,000 ft of the 9,745 ft runway, to the same scale as the side view.
The 901 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 15 minutes and covered a distance of 2 nautical miles. The aircraft, a Cessna C172, then departed from runway 01L at San Francisco International Airport (KSFO) with a takeoff distance of 4,313 feet, which was 59% of the runway length. The liftoff speed was 156 knots.
As the aircraft climbed out of KSFO, it encountered local weather conditions of 58°F temperature and a wind of 2 knots at 68°. The crosswind was 1 knot, and the headwind was also 1 knot. The enroute climb started 1 mile northeast of KSFO and reached an altitude of 14,999 feet above sea level (asl) in 10 minutes, covering a distance of 29 nautical miles.
The aircraft then entered a level cruise phase, which started 1 mile south of Bay Point, California, and lasted for 12 minutes, covering a distance of 42 nautical miles. The next enroute climb started 1 mile southwest of Rosemont, California, and reached an altitude of 38,042 feet asl in 25 minutes, covering a distance of 95 nautical miles.
The aircraft then entered another level cruise phase, which started 1 mile southeast of Reno Tahoe International Airport (KRNO) and lasted for 2 minutes, covering a distance of 7 nautical miles. The next enroute climb started 4 miles east of Sparks, Nevada, and reached an altitude of 39,045 feet asl in 2 minutes, covering a distance of 7 nautical miles.
The aircraft then began its descent, starting 3 miles south of Spanish Springs Airport (KSPN) and descending from 38,992 feet asl to 34,285 feet asl in 14 minutes, covering a distance of 54 nautical miles. The next descent started 14 miles southeast of Black Rock City Airport (88NV) and descended from 33,753 feet asl to 30,373 feet asl in 9 minutes, covering a distance of 30 nautical miles.
The aircraft then entered another level cruise phase, which started 9 miles north of Sulphur Airport (NV41) and lasted for 3 minutes, covering a distance of 10 nautical miles. The next descent started 15 miles southeast of Paiute Meadows Airport (02NV) and descended from 29,325 feet asl to 21,003 feet asl in 13 minutes, covering a distance of 35 nautical miles.
The aircraft then entered another level cruise phase, which started 20 miles southeast of Denio Junction Airport (E85) and lasted for 13 minutes, covering a distance of 31 nautical miles. The next descent started 15 miles southeast of Whitehorse Ranch Airport (OR09) and descended from 20,997 feet asl to 6,218 feet asl in 22 minutes, covering a distance of 49 nautical miles.
The aircraft then entered another level cruise phase, which started 10 miles south of Skinner Ranch Airport (12OR) and lasted for 2 minutes, covering a distance of 3 nautical miles. The next climb started 8 miles southeast of Skinner Ranch Airport and climbed from 5,998 feet asl to 6,989 feet asl in 3 minutes, covering a distance of 7 nautical miles.
The aircraft then entered another level cruise phase, which started 10 miles east of Skinner Ranch Airport and lasted for 3 minutes, covering a distance of 7 nautical miles. The next descent started 15 miles east of Skinner Ranch Airport and descended from 6,787 feet asl to 6,306 feet asl in 2 minutes, covering a distance of 3 nautical miles.
The aircraft then
The Cessna C172 aircraft successfully landed on runway 10R at KBOI Boise Air Terminal/Gowen Field, achieving an overall score of 85.6%. The final approach was initiated from the west, heading 115.0° at a distance of 4 nautical miles and an altitude of 1,201 feet above ground level (agl).
The aircraft touched down on the runway with a good threshold height, indicating a well-executed approach. However, the threshold speed was excessively high at 139 knots, suggesting that the pilot may have been able to flare the aircraft more effectively to reduce the touchdown speed. The touchdown speed of 137 knots was also found to be excessively fast, which could have resulted in a harder touchdown.
Despite the high touchdown speed, the touchdown distance of 907 feet was considered good. The touchdown rate of -430 feet per minute (fpm) was also found to be hard, indicating that the aircraft may have been subjected to a significant amount of deceleration upon touchdown. The runway touchdown alignment was very good, indicating that the pilot maintained a stable and aligned approach to the runway.
The local weather conditions at the time of the landing were favorable, with a temperature of 44°F and a wind speed of 1 knot from the north. The crosswind component was minimal at 1 knot, and the headwind component was zero. These conditions would have made the landing relatively straightforward.
The total landing distance of 3,665 feet was 38% of the runway length, indicating that the aircraft was able to stop within a reasonable distance. The runway rollout alignment was perfect, suggesting that the pilot maintained control of the aircraft during the rollout phase and was able to bring the aircraft to a stop in a stable and aligned manner. Overall, the landing was considered successful, but there were some areas for improvement, particularly in terms of reducing the touchdown speed and touchdown rate.
