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 75 kt with 3.8° 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 380 ft.
Reached 35 ft with 385 m of runway left; then climbing at 940 fpm on average to 380 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 827 m runway.
Rolled from the start of the runway, drifted right of the centreline, 5 m at the widest, and lifted off 5 m right. Airborne 21 % 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 final from 4 nm.
Profile height against the 3° glideslope, with its 2° band in green.
Inside the glideslope band from 3.0 nm, where the final began, to the threshold, never more than 430 ft below 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.
Joined 354 m right of the centreline at 3.0 nm, then drifted 172 m left between 2.6 and 1.2 nm, then inside the band from 1.2 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 3.0 nm, where the final began, to 0.2 nm, then fast to the threshold (up to +16 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
No crosswind: nothing to correct for. Touched down straight, wings level.
Wind 070° at 5 kt · 4 kt tail · 0 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 80 kt at touchdown to taxi speed (30 kt) in 12 s, an average deceleration of 0.24 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 1,524 m of the approach.
Crossed the threshold at 13 ft, 37 ft below the 50 ft target. Touched down 231 m in, 74 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 480 fpm at 12 ft to 160 fpm at touchdown. The nose came up 3.0° 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 3,193 m runway, to the same scale as the side view.
Touched down on the centreline, and stayed within 1.6 m of it down 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 231 m touchdown sits inside the full-score zone. The 1.30 G arrival bounced.
The rest of the report
The flight began with a taxiing period from the parking area to the runway, which took approximately 3 minutes and covered less than 1 nautical mile. The aircraft, a Piper PA28 Turbo Arrow IV, then departed from runway 28 at KCDW Essex County Airport. The takeoff distance was 320 meters, which accounted for 39% of the runway. The liftoff speed was 76 knots.
The local weather conditions at the time of departure were characterized by a temperature of 14°C, with a wind speed of 0 knots at 180°. There was no crosswind or headwind. The aircraft then began its enroute climb, starting overhead Fairfield, New Jersey, and ascending from 582 feet above sea level to 6,771 feet above sea level, an increase of 6,190 feet in 6 minutes, covering a distance of 11 nautical miles.
Following the initial climb, the aircraft entered a level cruise, starting 1 mile west of Morristown, New Jersey, and lasting 9 minutes, covering a distance of 25 nautical miles. The aircraft then began its descent, starting 1 mile southwest of Flemington, New Jersey, and descending from 7,389 feet above sea level to 1,055 feet above sea level, a decrease of 6,334 feet in 5 minutes, covering a distance of 12 nautical miles.
The aircraft then entered another level cruise, starting 2 miles north of Newtown Grant, Pennsylvania, and lasting 9 minutes, covering a distance of 23 nautical miles. The final descent began overhead RB17 Philadelphia Delaware Philadelphia, Pennsylvania, and the aircraft descended from 1,356 feet above sea level to 548 feet above sea level, a decrease of 808 feet in 2 minutes, covering a distance of 5 nautical miles.
The final approach to runway 27L at KPHL Philadelphia International Airport was made from the east, heading 259.0° at 2 nautical miles and 529 feet above ground level. The landing was successful, with a touchdown distance of 230 meters, which was good. The touchdown speed was 76 knots, which was a little fast, but the touchdown rate was good at -163 feet per minute. The runway touchdown alignment was perfect, and the runway rollout alignment was also perfect.
The local weather conditions at the time of landing were characterized by a temperature of 13°C, with a wind speed of 4 knots at 70°. There was no crosswind, but a tailwind of 4 knots. The total landing distance was 524 meters, which accounted for 16% of the runway. The total flight distance was 77 nautical miles, taking 33 minutes, and the aircraft used 25 kilograms of fuel.
