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 108 kt with 7.7° 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 50 ft.
Reached 35 ft with 1,104 m of runway left.
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 3,344 m runway.
Rolled from 1,668 m in, drifted 6 m left of the centreline and was back on it to lift off. Airborne 60 % 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.
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, 1.9 nm out at 190 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.
Rough: the G force varied more than a smooth turn and leg would.
Each lap slightly wider and higher than the last, because you're unconsciously using the previous lap as your reference instead of the runway and the numbers. Invisible lap to lap, unmistakable across ten. This is the failure that only measurement catches, because your memory of lap three is gone by lap eight.

Late: turned base with the threshold 19° behind, against 45°.
The stopwatch. From abeam the threshold, fly roughly 30 to 45 seconds before turning base, in nil wind at 172 speeds. Treat that as a starting value and calibrate it. If your finals keep coming out at 400 ft instead of 500, add a few seconds. Then adjust for wind, roughly a second per knot of headwind on final (a headwind on final is a tailwind on downwind, carrying you further from the field per second).
Read more in Pattern WorkThe final from 4 nm.
Profile height against the 3° glideslope, with its 2° band in green.
On the glideslope from 1.1 nm, where the final began, to 0.2 nm, then low to the threshold (up to 80 ft under).
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.
Joined 457 m left of the centreline at 1.1 nm, then inside the band from 0.7 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 78 kt fast at the 1,000 ft gate, closing to 48 at 500 ft and 10 at the threshold.
Inside the speed band from 1.1 nm, where the final began, to 0.9 nm, then fast to the threshold (up to +33 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
Calm: nothing to correct for. Touched down with the nose 4° right of the track, wings level.
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 460 m in, 155 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.
From 16 ft the descent stopped and turned into a climb of 170 fpm before coming down at 260 fpm to touch. The nose came up 5.4° 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 3,344 m runway, to the same scale as the side view.
Touched down 7.4 m left of the centreline, and stayed about there down the rollout, 9.6 m left at the widest.
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 460 m touchdown sits inside the full-score zone. The 1.48 G arrival bounced 5 times.
The rest of the report
The flight began with a departure roll from runway 06 at LFPO Paris-Orly Airport. The aircraft, a BF 109G-6, accelerated down the runway and lifted off at a speed of 108 kt, covering a distance of 366 m, which accounted for 11% of the runway. The local weather conditions were favorable, with a temperature of 23 °C and a wind speed of 0 kt at 322 °.
As the aircraft entered the left-hand pattern, it followed a standard procedure, making a left-hand turn from the runway. The distance covered during this turn was less than 1 nm, and it took 36 seconds to complete. The subsequent left-hand pattern crosswind turn was even shorter, taking only 12 seconds to cover a distance of less than 1 nm.
The aircraft then proceeded to the downwind leg, where it turned at an angle of 99.5 ° to the runway. This turn covered a distance of 1 nm, and the aircraft continued on the downwind leg for 2 nm, taking 86 seconds to cover this distance. The base leg turn was another left-hand turn, which brought the aircraft closer to the runway. This turn covered a distance of 1 nm and was made at an angle of 19.4 ° to the runway.
The final approach to runway 06 was made from the south-west, with the aircraft heading 60.0 ° at an altitude of 93 ft above ground level (agl) and a distance of 0 nm from the runway. The landing was smooth, with the aircraft touching down 294 m beyond the touchdown zone. The touchdown speed was 87 kt, which was good, but the touchdown rate was fair at -257 fpm.
The runway touchdown position was slightly misaligned, being 9.6 m off the centerline. However, the runway rollout alignment was very good, and the aircraft came to a stop quickly. The total landing distance was 914 m, which accounted for 27% of the runway. The taxiing to the parking area took less than 1 minute and covered a distance of less than 1 nm.
The total flight distance was 6 nm, and the flight took 5 minutes to complete. The aircraft used 11 kg of fuel during the flight, indicating a relatively efficient performance. Overall, the flight was smooth and uneventful, with the aircraft performing well in the given weather conditions.
