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.

Two stabilised approach gates, each with six checks at 1,000 ft and 500 ft above the runway.
Side view — the last 2,928 m of the approach.
Plan view — the full 2,928 m runway, to the same scale as the side view.
Touched down 1,757 m 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 less than a minute and covering a distance of less than 1 nautical mile. The aircraft, a PA44 Seminole, then departed from runway 03L at O.R. Tambo International Airport, with a takeoff distance of 617 meters, which is 15% of the runway length. The liftoff speed was 77 knots, and the local weather conditions were characterized by a temperature of 16°C, a wind speed of 1 knot at 270°, with no crosswind or headwind.
As the aircraft climbed away from the airport, it began its enroute climb 1 mile north of O.R. Tambo International Airport, Johannesburg. The climb took 2 minutes, during which the aircraft ascended from 6,507 feet above sea level to 7,475 feet above sea level, an increase of 968 feet. The distance covered during this climb was 3 nautical miles.
Following the climb, the aircraft entered a level cruise phase, starting 3 miles south of Tembisa. This phase lasted for 2 minutes and covered a distance of 4 nautical miles. The aircraft then began its enroute descent 2 miles northwest of Modderfontein, descending from 7,350 feet above sea level to 6,530 feet above sea level, a decrease of 820 feet, in 2 minutes and covering 4 nautical miles.
The aircraft then entered another level cruise phase, starting 3 miles west of Edenvale, which lasted for 8 minutes and covered a distance of 14 nautical miles. After this cruise phase, the aircraft began its final approach to runway 07 at Lanseria International Airport, flying from the southwest at a heading of 51.0° and at an altitude of 1,148 feet above ground level, 4 nautical miles from the runway.
The landing on runway 07 at Lanseria International Airport was notable for several factors. The threshold height was significantly above the target, and the threshold speed was excessively high at 102 knots. The touchdown point was very long, using more than 50% of the available runway. However, the touchdown speed of 61 knots was good, and the touchdown rate was smooth at -139 feet per minute. The runway touchdown alignment was very good.
The local weather conditions at the time of landing were characterized by a temperature of 15°C, a wind speed of 1 knot at 270°, with a crosswind of 1 knot and a tailwind of 1 knot. The total landing distance was 2,973 meters, which is 102% of the runway length. After landing, the aircraft taxied to the parking area, taking less than a minute and covering a distance of less than 1 nautical mile.
In total, the flight distance was 33 nautical miles, and the flight duration was 18 minutes. Notably, the aircraft used 0 kilograms of fuel during the flight.
The PA44 Seminole aircraft successfully landed on runway 07 at FALA Lanseria International Airport, but the landing was not without its challenges. The final approach was initiated from the south west, heading 51.0° at 4 nautical miles and 1,148 feet above ground level (agl). The aircraft touched down on the runway, but the touchdown point was significantly long, utilizing more than 50% of the available runway.
The landing performance was affected by the threshold height, which was significantly above the target height at 92 feet agl. Additionally, the threshold speed was excessively high at 102 knots, indicating that the aircraft was not properly configured for landing. Despite these issues, the touchdown speed of 61 knots was good, and the touchdown rate was smooth at -139 feet per minute (fpm). The runway touchdown alignment was very good, indicating that the aircraft was properly aligned with the runway.
The local weather conditions at the time of the landing were relatively calm, with a temperature of 15°C and a wind speed of 1 knot from 270°. The crosswind and tailwind components were both 1 knot, which had a minimal impact on the landing. However, the total landing distance of 2,973 meters was 102% of the available runway, indicating that the aircraft could have benefited from a shorter landing distance.
The runway rollout alignment was slightly misaligned by 14.2 meters from the centreline, which may have been due to the aircraft's long touchdown point. Overall, while the landing was successful, there were several areas for improvement, including reducing the threshold height and speed, and improving the touchdown point to reduce the landing distance.
