Departure
Start bringing the nose up as the speed reaches 50 kt, not after it.
What happened: You started the rotation at 65 kt, 15 kt past the 50 kt rotation speed.
Watch for: Airspeed indicator: 50 kt at rotation
See Departure Roll
Arrival
Reduce power earlier on final so threshold speed settles at 52 kt instead of carrying it into the flare.
What happened: You crossed the threshold at 76 kt, well above the 52 kt target speed, and that excess speed was still showing at touchdown. Crossing the threshold fast usually carries straight through to a fast touchdown.
Watch for: Airspeed indicator against 52 kt on short final.
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.

Taxi out
The roll
Rotated late
The nose came up at 65 kt, 15 kt after the 50 kt rotate speed.
The pull started after the rotate speed had gone by. Bring the airspeed into the scan as it approaches the rotate speed, so the pull starts on the number rather than when you notice it has passed.
Liftoff and climb
Plan view the roll down the 3,709 m runway.
Rolled from 309 m in, drifted left of the centreline, 3.7 m at the widest, and lifted off 2.3 m left. Airborne 16 % 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.
Side view from the start of the roll to 366 ft.
Reached 35 ft with 2,658 m of runway left; then climbing at 340 fpm on average to 366 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. The dark stretch of the roll is the run with the nose up and the wheels still on, with its length and time under the runway.
Speed and pitch from brake release to the end of the climb, against time.
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 dashed green line is the speed to rotate at for this aircraft at its weight, and the green dot is where the nose started to come up. The grey band is the run between the nose coming up and the wheels leaving the runway. The figures at liftoff are the pitch then and how fast the nose came up, in degrees a second. The grey dashed line across the pitch is the attitude held from 35 ft to the end: a nose held steady is a climb speed that holds, and the airspeed trace sits directly above it to compare.
Over the threshold
Excellent landing flare
It lost 0.2 points, for taking only 97 fpm of the sink out.
Touchdown
Rollout
Side view — the last 1,524 m of the approach.
Crossed the threshold at 30 ft, 20 ft below the 50 ft target; began the flare at 12 ft. Touched down 410 m in, 105 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 160 fpm at the flare to 60 fpm at 6 ft, then back up to 140 fpm at touchdown. The nose came up 0.9° on the way down. Into the flare at 68 kt, 16 kt over the 52 kt approach speed, and 58 kt at touchdown.
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 3,709 m runway, to the same scale as the side view.
Touched down 15 m left of the centreline, and steered back to 5.8 m left by the end of the rollout. Little crosswind (2 kt): nothing to correct for. Touched down with the nose 3° right of the track, wings level.
Wind 100° at 5 kt · 4 kt head · 2 kt across
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 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. The sentence gives the nose against the direction you were actually moving as the wheels touched, and the steepest bank as they touched, the figure the touchdown's Bank tile marks. The rest of it is shown for reading, not marked.
The 410 m touchdown sits inside the full-score zone. The arrival was smooth.
The stop — touchdown to taxi speed.
From 57 kt at touchdown to taxi speed (30 kt) in 9 s, an average deceleration of 0.16 g.
Your ground speed from the moment the wheels touched until you were down to taxi speed, against the distance rolled. A steep line is hard braking, a shallow one a long, gentle roll. For scale, an airliner's lowest autobrake setting decelerates at about 0.15 g, a medium one about 0.3 g. Shown for reading; not marked.
The rest of the report
The aircraft departed from runway 06 at LKPR Václav Havel Airport, Prague. Take-off was performed on a 604 m roll, representing 16 % of the runway length. Rotation occurred at 65 kt. Local weather at departure was temperature 3 °C, wind 5 kt from 100°, giving a 3 kt crosswind component and a 4 kt headwind component.
Initial climb continued to 400 ft agl in 62 seconds, with an average climb rate of 404 fpm and a speed increase to 140 kt at the top of the climb. The aircraft then leveled at 1 800 ft asl for the cruise phase, remaining in level flight for 4 minutes while covering 7 nm, beginning the segment overhead Knezeves.
Descent and approach were made for runway 06 at the same airport. The landing threshold was noted as good, but the threshold speed was excessively high at 76 kt. The flare was described as excellent. Touchdown occurred at a speed of 58 kt, which was excessively fast, with a smooth touchdown rate of minus 141 fpm. The touchdown point was 409 m down the runway, a good distance, but the aircraft was significantly misaligned by 15.5 m from the centreline. No bounce was observed.
The total landing roll measured 619 m, representing 17 % of the runway length, and the rollout alignment was slightly misaligned by 10.4 m from the centreline. Local weather at landing matched departure conditions: temperature 3 °C, wind 5 kt from 100°, crosswind 3 kt, headwind 4 kt.
The complete flight covered 10 nm, lasted 5 minutes, and consumed 1 kg of fuel.
