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.

From brake release to the end of the climb, against time, then the takeoff point by point.
Lifted off at 68 kt with 11.3° 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 199 ft.
Reached 35 ft with 412 m of runway left; then climbing at 740 fpm on average to 199 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 935 m runway.
Rolled from 50 m in, drifted left of the centreline, 18 m at the widest, and lifted off 17 m left. Airborne 36 % 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.
wheel landing
Over the threshold
Touchdown
Excellent landing flare
Little crosswind (1 kt): nothing to correct for. Touched down with the nose 3° left of the track, 4° of bank.
Wind 261° at 4 kt · 4 kt tail · 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 46 ft, close to the 50 ft target; began the flare at 41 ft. Touched down 217 m in, 88 m short of 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 960 fpm at the flare to 560 fpm at touchdown. The pitch barely changed.
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 full 1,524 m runway, to the same scale as the side view.
Touched down 18 m right of the centreline, and steered back to 7.6 m right by the end of the rollout.
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.
The 217 m touchdown sits inside the full-score zone. The 2.21 G arrival bounced 6 times.
The rest of the report
Departure from Braga Municipal Aerodrome, LPBR, commenced with a smooth departure roll on runway 07. The Grumman Goose accelerated down the 360-meter runway, covering 38% of its length, before lifting off at a speed of 69 knots. Local weather conditions were favorable, with a temperature of 18°C and a gentle wind of 4 knots from 293 degrees, resulting in a negligible crosswind component.
As the aircraft climbed away from Braga, it quickly gained altitude, rising from 320 feet above sea level to 2,488 feet in just 3 minutes, covering a distance of 7 nautical miles. The enroute climb phase was followed by a brief level cruise, lasting 3 minutes and covering 5 nautical miles, before the aircraft began its descent towards its destination. The descent from 2,753 feet to 1,914 feet in 2 minutes, covering 4 nautical miles, was a smooth and controlled phase of the flight. The aircraft then leveled off again, cruising at 2,000 feet for 2 minutes, before commencing its final descent.
The final approach to landing was initiated overhead Viana do Castelo, with the aircraft descending from 256 feet above ground level to touch down at 0 feet in just 3 seconds. However, the touchdown speed of 100 knots was excessively high, resulting in a heavy touchdown rate of -610 feet per minute. The touchdown distance of 217 meters was satisfactory, but the high touchdown speed highlighted the need for further attention to the aircraft's approach and landing technique. Following touchdown, the aircraft taxied to the parking area, covering a distance of less than 1 nautical mile in 1 minute. The total flight distance was 30 nautical miles, with a fuel consumption of 37 kilograms, and a total flight time of 18 minutes.
