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 161 kt with 8.9° 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 shaded stretch is Climb 3, the part of the climb scored on holding the climb speed.
The takeoff, point by point
Side view from the start of the roll to the end of Climb 3 at 988 ft.
Reached 35 ft with 2,187 m of runway left; then climbing at 2,680 fpm on average to 988 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 shaded stretch is Climb 3, scored on its average speed against the target.
Plan view the roll down the 3,807 m runway.
Rolled from 149 m in, drifted left of the centreline, 3.2 m at the widest, and lifted off 2.5 m left. Airborne 37 % 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 1° band in green.
On the glideslope from 4 nm to 0.6 nm, then high to the threshold (up to 80 ft over).
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 18× larger than distances along the final.
Inside the 1° band from 4 nm to 0.4 nm, then 14 m left of it from 0.4 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 32 kt fast at the 1,000 ft gate, closing to 18 at 500 ft and 10 at the threshold.
Outside the speed band twice; furthest −8 kt at 1.4 nm.
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
Little crosswind (2 kt): nothing to correct for. Touched down straight, wings level.
Wind 320° at 4 kt · 3 kt head · 2 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 121 kt at touchdown to taxi speed (30 kt) in 27 s, an average deceleration of 0.19 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 55 ft, close to the 50 ft target. Touched down 421 m in, 116 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 1,010 fpm at 51 ft to 280 fpm at touchdown. The nose came up 2.9° 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 3,807 m runway, to the same scale as the side view.
Touched down on the centreline and drifted to 5.4 m left on the rollout, back to 0.5 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 421 m touchdown sits inside the full-score zone. The arrival was smooth.
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 a distance of less than 1 nautical mile. The aircraft, a Boeing 737-MAX8, then departed from runway 13L at Cologne Bonn Airport (EDDK). The takeoff distance was 1,271 meters, which is 33% of the runway length. The liftoff speed was 162 knots.
The local weather conditions at the time of takeoff were characterized by a temperature of 18°C and a wind speed of 4 knots from a direction of 340°. This resulted in a crosswind of 1 knot and a tailwind of 3 knots. The aircraft began its enroute climb overhead Cologne Bonn Airport, rising from an altitude of 1,308 feet above sea level to 3,345 feet above sea level in just 1 minute, covering a distance of 3 nautical miles.
The enroute level cruise phase started overhead Lohmar, lasting for 10 minutes and covering a distance of 7 nautical miles. The aircraft then began its enroute descent 3 miles south east of Hennef, descending from 3,100 feet above sea level to 2,108 feet above sea level in 2 minutes, covering a distance of 4 nautical miles. The descent phase was followed by a brief level cruise phase, which started 1 mile west of the Eudenbach glider field and lasted for 3 minutes, covering a distance of 8 nautical miles.
The final approach to runway 31R at Cologne Bonn Airport was made from the south east, with the aircraft heading 318.0° at a distance of 4 nautical miles and an altitude of 1,347 feet above ground level. The landing was executed on runway 31R, which has a length of 3,807 meters. The threshold height was slightly above the target, while the threshold speed was slightly below the target at 134 knots.
The touchdown distance was good at 421 meters, with a touchdown speed of 125 knots and a touchdown rate of -282 feet per minute, which was considered fair. 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 15°C and a wind speed of 4 knots from a direction of 320°, resulting in a headwind of 4 knots and no crosswind.
The total landing distance was 1,430 meters, which is 38% of the runway length. The total flight distance was 29 nautical miles, and the flight duration was 23 minutes. The aircraft used a total of -4,876 kilograms of fuel during the flight.
