See Departure Roll
A small uncorrected heading error at 40 knots becomes a metre of offset per second by 100 knots, noticed only at rotation, producing a crabbed liftoff. Root cause is nearly always eyes on the tape instead of the far end of the runway. Small heading changes displace a distant point visibly long before the nearby centreline stripes look wrong.

From brake release to the end of the climb, against time, then the takeoff point by point.
Lifted off at 52 kt with 4.0° 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 48 ft.
Reached 35 ft with 2,165 ft 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 4,787 ft runway.
Rolled from 985 ft in, drifted right of the centreline, 28 ft at the widest, and lifted off 28 ft right. Airborne 31 % 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.
The final from 4 nm.
Profile height against the 3° glideslope, with its 2° band in green.
Inside the glideslope band from 3.8 nm, where the final began, to the threshold, never more than 610 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, 1,000 ft 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 3.8 nm, where the final began, to 3.3 nm, then drifted 410 ft left between 3.3 and 2.6 nm, then inside the band from 2.6 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 3.8 nm, where the final began, to 0.3 nm, then fast to the threshold (up to +17 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
4 kt across from the left, which takes about 4° of crab to hold the centreline at 61 kt. Touched down with 4° of it still on, wings level.
Wind 342° at 5 kt · 1 kt tail · 4 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 61 kt at touchdown to taxi speed (30 kt) in 8 s, an average deceleration of 0.21 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 2,142 ft of the approach.
Crossed the threshold at 23 ft, 27 ft below the 50 ft target. Touched down 756 ft in, 244 ft short of the ideal 1,000 ft.
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 2,142 ft across. The dashed line is the ideal, 50 ft over the threshold and down 1,000 ft 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 460 fpm at 22 ft to 150 fpm at touchdown. The nose came up 4.2° 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 2,142 ft runway, to the same scale as the side view.
Touched down 32 ft left of the centreline and drifted to 49 ft left on 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 756 ft touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The flight began with taxiing from the parking area to the runway, which took approximately 4 minutes and covered a distance of less than 1 nautical mile. The aircraft, a Cessna C182, then departed from runway 21 at EGMD Lydd London Ashford Airport. The takeoff distance was 570 feet, which accounted for 12% of the runway length. The liftoff speed was 53 knots, and the local weather conditions at the time of departure were characterized by a temperature of 65°F and a wind speed of 5 knots from a direction of 340°.
The aircraft then entered a level cruise, starting overhead EGMD Lydd London Ashford Airport Romney Marsh, and lasted for less than 1 minute, covering a distance of less than 1 nautical mile. Following this brief cruise, the aircraft began an enroute climb, ascending from an altitude of 154 feet above sea level to 2,883 feet above sea level, an increase of 2,729 feet, in 6 minutes and covering a distance of 4 nautical miles.
The aircraft then entered another level cruise, this time starting 1 mile north-east of Camber, East Sussex, England, and lasted for 58 minutes, covering a distance of 62 nautical miles. The final approach to runway 08 at EGTR Elstree Airfield was made from the west, with the aircraft heading 78.0° at a distance of 3 nautical miles and an altitude of 1,659 feet above ground level.
The landing on runway 08 at EGTR Elstree Airfield was successful, with the touchdown distance being 750 feet, which was considered good. However, the touchdown speed of 61 knots was a little fast, and the touchdown rate was smooth at -146 feet per minute. The runway touchdown position was misaligned by 32 feet from the centreline, and the runway rollout alignment was also misaligned by 51 feet from the centreline.
The local weather conditions at the time of landing were characterized by a temperature of 64°F and a wind speed of 5 knots from a direction of 341°. The total landing distance was 1,260 feet, which accounted for 59% of the runway length. The taxiing from the runway to the parking area took approximately 1 minute and covered a distance of less than 1 nautical mile. The total flight distance was 71 nautical miles, and the flight duration was 71 minutes, with the aircraft using 78 pounds of fuel.
