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 149 kt with 3.1° 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 966 ft.
Reached 35 ft with 5,852 ft of runway left; then climbing at 1,980 fpm on average to 966 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 10,247 ft runway.
Rolled from the start of the runway, drifted right of the centreline, 10 ft at the widest, and lifted off 7 ft right. Airborne 35 % 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.
High from 0.7 nm, where the final began, to 0.4 nm (up to 130 ft over), then back on it to the threshold.
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.
Joined 1,660 ft left of the centreline at 0.7 nm.
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.
Over the threshold
Touchdown
Little crosswind (1 kt): nothing to correct for. Touched down straight, wings level.
Wind 320° at 4 kt · 4 kt head · 1 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.
Side view — the last 5,000 ft of the approach.
Crossed the threshold at 35 ft, 15 ft below the 50 ft target. Touched down 1,318 ft in, 318 ft past 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 5,000 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 540 fpm at 33 ft to 130 fpm at touchdown. The nose came up 3.4° 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 5,000 ft of the 11,462 ft runway, to the same scale as the side view.
Touched down 9 ft left of the centreline, and stayed about there down the rollout, 10 ft 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 arrow beside the runway is the crosswind, pointing the way the air was moving, so it pushed the aircraft that way.
The 1,318 ft touchdown sits inside the full-score zone. The 1.11 G arrival bounced.
The rest of the report
The flight began with a taxiing period from the parking to the runway, which took 8 minutes and covered a distance of 2 nautical miles. The aircraft, a B-2 Spirit, then departed from runway 02 at LPPT Humberto Delgado Airport, also known as Lisbon Portela Airport. The takeoff distance was 3,566 feet, which is 35% of the runway length. The aircraft lifted off at a speed of 150 knots.
The local weather conditions at the time of takeoff were characterized by a temperature of 62 degrees Fahrenheit and a wind speed of 6 knots at a direction of 60 degrees. This resulted in a crosswind of 4 knots and a headwind of 5 knots. The aircraft climbed to a height of 36,825 feet above sea level, an increase of 35,456 feet from the initial altitude of 1,369 feet. This climb took 14 minutes and covered a distance of 88 nautical miles.
The enroute climb started over Camarate, a location in the Distrito de Lisboa, Portugal. The aircraft then entered a level cruise phase, which began 3 miles south of Cedillo in Extremadura, Spain. This phase lasted for 133 minutes and covered a distance of 1,073 nautical miles.
As the aircraft approached its destination, it began its descent over Kleinreifling in Oberoesterreich, Austria. The descent took 15 minutes and covered a distance of 81 nautical miles, during which the aircraft decreased its altitude from 36,722 feet to 673 feet above sea level.
The final approach to runway 29 at LOWW Vienna International Airport was made from the southeast, heading 300.0 degrees at an altitude of 85 feet above ground level. The local weather conditions at the time of landing were characterized by a temperature of 36 degrees Fahrenheit and a wind speed of 4 knots at a direction of 320 degrees. This resulted in a crosswind of 2 knots and a headwind of 4 knots.
The landing was successful, with a touchdown speed of 124 knots and a smooth touchdown rate of -130 feet per minute. The touchdown distance was 1,319 feet, which is 32% of the runway length. The runway touchdown position was slightly misaligned by 10 feet from the centerline. The runway rollout alignment was perfect, and the aircraft taxied to the parking area in less than 1 minute, covering a distance of less than 1 nautical mile.
The total flight distance was 1,246 nautical miles, and the flight duration was 171 minutes. The aircraft used a total of 43,787 pounds of fuel during the flight.
