Arrival
Reduce power earlier on final so threshold speed settles at 77 kt instead of carrying it into the flare.
What happened: You crossed the threshold at 108 kt, well above the 77 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 77 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.

From brake release to the end of the climb, against time, then the takeoff point by point.
Rotated at 92 kt, 11 kt below the 103 kt target, and lifted off at 102 kt 2.0 s later, the nose coming up at 1.3° a second.
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 figures at liftoff are the pitch then and how fast the nose came up, in degrees a second.
The takeoff, point by point
Side view from the start of the roll to 696 ft. The distance scale changes past the runway end.
Reached 35 ft with 268 m of runway left; then climbing at 1,390 fpm on average to 696 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 1,093 m runway.
Rolled from 17 m in, drifted left of the centreline, 2 m at the widest, and lifted off 1.2 m right, in 8 kn of crosswind from the right. Airborne 44 % 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.
Left-hand, 1,000 ft circuit height. The plan shows your circuit over a textbook one for this runway; the profile unrolls the same path from liftoff to the threshold.
Plan landing direction to the left; in pale blue the textbook circuit for your downwind speed, 1.1 nm out at 112 kt
The lap from above, with the landing direction to the left: the opposite of the runway drawings. The wide pale-blue line is a textbook circuit for your downwind speed - the downwind a mile out for every 100 kt, every turn at 30° of bank - and your track is drawn over it, each leg in the colour of its mark. The numbers are the four turns, the same as on the profile and the cards below. The 45° line from the threshold is the usual point to turn onto base.
Around the circuit height and bank; the turns are shaded
The same lap straightened out, so the height and the bank can be read together. Each shaded stretch is a turn, numbered as on the plan. The green box is circuit height, 1,000 ft, on the downwind. The amber line is 30° of bank, and a turn's steepest bank shows red above 32°. "Turn crosswind from" is the lowest height to start the first turn at.
Good: full marks on the turn and the leg after it.

The final from 4 nm.
Profile height against the 3° glideslope, with its 2° band in green.
Inside the glideslope band from 1.8 nm, where the final began, to the threshold, never more than 300 ft above the slope.
Your height above the runway against the distance still to go. The glideslope is the steady descent path to the aiming point, 305 m past the threshold: 3° here, which is about 320 ft for every nautical mile out, crossing the threshold at about 50 ft. The row under the distances is the height it puts you at. Inside the green band your path is drawn green; outside it, amber.
Plan distance off the extended centreline, your left at the top, with the 1° band. Sideways distances are drawn 3× larger than distances along the final.
Inside the 1° band from 1.8 nm, where the final began, to 1.2 nm, then drifted 43 m left between 1.2 and 0.9 nm, then inside the band from 0.9 nm to the threshold.
Looking down from above, flying left to right towards the runway: up the page is left of the centreline, down is right. Sideways distances are stretched so that small drifts show, so a line that looks wild here may be only a few tens of feet. The labels are how far off you were at each distance, amber when outside the band.
Speed against the approach speed. The green band runs from 5 kt slow to 39 kt fast at the 1,000 ft gate, closing to 23 at 500 ft and 10 at the threshold.
Fast from 1.8 nm, where the final began, to the threshold (up to +44 kt).
Your indicated airspeed down the final, against the approach speed for this aircraft at its landing weight. The band allows 5 kt slow and more on the fast side further out, closing as you get lower, because the speed is expected to come off on the way down. The figures are knots above (+) or below (−) the approach speed.
Over the threshold
Touchdown
The flare strayed well off the target profile. Crossing the threshold 31 kt above target, the flare took all the sink out 42 ft agl above the runway and the aircraft then dropped the rest of the way, 1,024 fpm of sink coming back. Touchdown was 159 m past the threshold. Hold the attitude and let it settle rather than pushing - that excess speed is what turns a normal flare into a balloon, so the fix is on the approach, not in the flare.
9 kt across from the right, which takes about 5° of crab to hold the centreline at 101 kt. Touched down with 3° of it still on, wings level.
Wind 008° at 10 kt · 3 kt head · 9 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.
From 97 kt at touchdown to taxi speed (30 kt) in 20 s, an average deceleration of 0.18 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.
Side view — the last 1,093 m of the approach.
Began the flare at 42 ft, 360 m before the threshold; crossed the threshold at 10 ft, 40 ft below the 50 ft target. Touched down 159 m in, 146 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 1,093 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 930 fpm at the flare to 270 fpm at touchdown. The nose came up 0.6° 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 full 1,093 m runway, to the same scale as the side view.
Touched down 2 m right of the centreline and drifted to 8.7 m right on the rollout, back to 3.1 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.
The 159 m touchdown sits inside the full-score zone. The 1.03 G arrival bounced.
The rest of the report
The Lancair Legacy taxied to runway 30 at LFLI Annemasse Airfield and commenced the take-off roll. The takeoff distance was 506 m, which is 46 % of the runway. Rotation occurred at 92 kt. Local weather at departure was temperature 7 °C, wind 10 kt from 008°, giving a crosswind component of 9 kt and a headwind component of 3 kt.
Initial climb to 400 ft agl took 28 seconds, averaging 1,194 fpm and reaching 116 kt at the top of the climb. The aircraft then entered a left-hand circuit for runway 30. The downwind leg was 4 nm and was flown in 114 seconds at 990 ft agl. The base leg was 1 nm and was completed in 40 seconds.
Final approach to runway 30 began from 943 ft agl and descended to 33 ft agl in 55 seconds. Stabilisation checks at 500 ft above the runway showed gear down and landing flap met, but speed was not met. The aircraft was not scored on a circuit; the stabilisation gate is shown for reference only.
Landing on runway 30 was performed with a threshold speed of 108 kt, noted as excessively high. The flare was very poor; the aircraft ballooned in the flare. Touchdown occurred at 100 kt, also excessively fast, with a touchdown rate of minus 269 fpm. Touchdown distance was 159 m, described as good, and runway-touchdown alignment was very good. One bounce occurred on touchdown. Total landing distance was 625 m, representing 57 % of the runway. Runway rollout alignment was slightly misaligned by 8.7 m from the centreline.
After landing, the aircraft taxied to parking in 6 minutes, covering less than 1 nm. The total flight covered 12 nm in 12 minutes and used 5 kg of fuel. Local weather at landing was temperature 7 °C, wind 9 kt from 007°, with a crosswind of 9 kt and a headwind of 3 kt.
