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 approach before the go-around was abandoned. Its marks are shown, but only the approach that landed counts.

From brake release to the end of the climb, against time, then the takeoff point by point.
Lifted off at 66 kt with 1.5° of pitch.
Two traces from brake release: the airspeed on top, and below it the pitch, which is how far the nose is above the horizon. The figure at liftoff is the pitch then.
The takeoff, point by point
Side view from the start of the roll to 175 ft.
Reached 35 ft with 1,993 m of runway left; then climbing at 800 fpm on average to 175 ft.
The takeoff from the side: the height above the runway against the distance along it. The numbers along the runway are the speeds reached at each point. Lifting off in the amber last quarter of the runway costs marks for the roll length.
Plan view the roll down the 2,255 m runway.
Rolled from the start of the runway, drifted right of the centreline, 2.1 m at the widest, and lifted off 2.2 m right. Airborne 0 % of the way down the runway, before the 75 % line.
The roll from above, with your left at the top. The line is where the wheels went, and "widest" is the furthest you drifted off the centreline. Lifting off before the amber 75 % line gets full marks for the roll length. The arrow beside the runway is the crosswind, pointing the way the air was moving, so it pushed the aircraft that way.
Over the threshold
Touchdown
Little crosswind (1 kt): nothing to correct for. Touched down with the nose 2° right of the track, wings level.
Wind 194° at 25 kt · 24 kt head · 1 kt across
The wind is the one recorded at the landing, split along the runway (headwind or tailwind) and across it. To hold the centreline in a crosswind the nose points a little into wind - the crab - and is straightened with rudder just before the wheels touch, often with the into-wind wing lowered to stop the drift. These are the nose against the direction you were actually moving, and the wings, at the moment of touchdown. Shown for reading; not marked.
Side view — the last 1,524 m of the approach.
Crossed the threshold at 17 ft, 33 ft below the 50 ft target. Touched down 539 m in, 234 m past the ideal 305 m.
The last stretch of the approach and the touchdown, from the side. The height is stretched so that the last few feet show: 80 ft top to bottom, against 1,524 m across. The dashed line is the ideal, 50 ft over the threshold and down 305 m in. The flare ring is where you began raising the nose, and "descent slowed" is where the sink came off; the figures beside them are the sink rate, pitch and speed at that point.
Sink and pitch — through the flare, lined up with the side view.
The sink went from 40 fpm at 14 ft to 30 fpm at touchdown. The nose came up 3.6° on the way down.
Lined up with the side view above, so a point on one sits under the same point of the other. On top, how fast you were coming down: 0 is level, and −600 is 600 ft a minute down. Below, the pitch. In a flare the nose comes up and the descent slows towards 0. The figure at the touchdown line is your touchdown rate.
Plan view — the first 1,524 m of the 2,255 m runway, to the same scale as the side view.
Touched down 3.9 m right of the centreline and drifted to 8.7 m right on the rollout, back to 0.3 m right by the end.
The runway from above, with your left at the top. Touching down inside the green bracket scores full marks for the distance. The shaded part is the rollout, up to where it ended. The arrow beside the runway is the crosswind, pointing the way the air was moving, so it pushed the aircraft that way.
Touched down 539 m past the threshold — beyond the full-score zone. The 1.04 G arrival bounced 9 times.
The rest of the report
The flight began with the departure roll from runway 21 at EHBK Maastricht Aachen Airport, where the Sirius aircraft took off with a takeoff distance of 200 meters, which is 9% of the runway. The liftoff speed was 66 knots. At the time of departure, the local weather conditions were characterized by a temperature of 15 degrees Celsius and a wind speed of 2 knots at 265 degrees, resulting in a crosswind of 2 knots and a headwind of 1 knot.
As the aircraft climbed, it started its enroute climb overhead Ulestraten, a location in the Provincie Limburg, The Netherlands. The climb began at an altitude of 608 feet above sea level and reached 1,272 feet above sea level, an increase of 664 feet in just 1 minute, while covering a distance of 2 nautical miles.
The enroute level cruise started 1 mile southwest of Elsloo, another location in the Provincie Limburg, The Netherlands. This phase of the flight lasted for 2 minutes and covered a distance of 2 nautical miles. Following the cruise, the aircraft began its final approach to runway 21 at EHBK Maastricht Aachen Airport from the northeast, heading at 217.0 degrees at an altitude of 161 feet above ground level.
However, the flight did not end with a smooth landing. A go-around was initiated at an altitude of 475 feet above ground level. The aircraft then made a second attempt at landing on runway 21, which has a length of 2,255 meters. The threshold height was good, but the threshold speed was above the target speed of 61 knots. The touchdown point was 135 meters beyond the touchdown zone, and the touchdown speed was 43 knots, which was considered good. The touchdown rate was also perfect at -29 feet per minute.
Despite the good touchdown speed and rate, the runway touchdown position was slightly misaligned by 3.9 meters from the centerline. The local weather conditions at the time of landing were characterized by a temperature of 15 degrees Celsius and a wind speed of 25 knots at 194 degrees, resulting in a crosswind of 8 knots and a headwind of 24 knots. The total landing distance was 1,041 meters, which is 46% of the runway. The runway rollout alignment was also slightly misaligned by 8.7 meters from the centerline.
In conclusion, the flight was a complex one, with a go-around and a second attempt at landing. Despite some minor issues with alignment, the touchdown speed and rate were good, and the total landing distance was within acceptable limits. The total flight distance was 6 nautical miles, and the flight used 1 kilogram of fuel.
