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 155 kt with 2.1° 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 957 ft.
Reached 35 ft with 6,828 ft of runway left; then climbing at 2,220 fpm on average to 957 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 11,462 ft runway.
Rolled from 130 ft in, drifted 11 ft left of the centreline and was back on it to lift off. Airborne 33 % 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.
Inside the glideslope band from 2.6 nm, where the final began, to the threshold, never more than 260 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.
Joined 2,160 ft left of the centreline at 2.6 nm, then inside the band from 1.3 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.
Over the threshold
Touchdown
4 kt across from the right, which takes about 2° of crab to hold the centreline at 120 kt. Touched down with the nose 3° into wind, wings level.
Wind 240° at 10 kt · 8 kt head · 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 111 kt at touchdown to taxi speed (30 kt) in 21 s, an average deceleration of 0.22 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 5,000 ft of the approach.
Crossed the threshold at 27 ft, 23 ft below the 50 ft target. Touched down 1,094 ft in, close to 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 410 fpm at 25 ft to 220 fpm at touchdown. The nose came up 1.4° 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 10,247 ft runway, to the same scale as the side view.
Touched down on the centreline, and stayed within 9 ft 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 arrow beside the runway is the crosswind, pointing the way the air was moving, so it pushed the aircraft that way.
The 1,094 ft touchdown sits inside the full-score zone. The 1.18 G arrival bounced.
The rest of the report
The flight began with a taxiing period from the parking to the runway, which took approximately 3 minutes and covered less than 1 nautical mile. The aircraft, a B-2 Spirit, then departed from runway 11 at LOWW Vienna International Airport. The takeoff distance was 3,673 feet, which accounted for 32% of the runway. The aircraft lifted off at a speed of 156 knots.
The local weather conditions at the time of takeoff were characterized by a temperature of 37 degrees Fahrenheit and a wind speed of 9 knots at 136 degrees. This resulted in a crosswind of 3 knots and a headwind of 9 knots. The aircraft then began its enroute climb, which started overhead LOWW Vienna International Airport and continued to an altitude of 38,223 feet above sea level. This climb phase covered a distance of 88 nautical miles and took 18 minutes to complete, with the aircraft increasing its altitude by 36,618 feet.
Following the enroute climb, the aircraft entered a level cruise phase, which lasted for 150 minutes and covered a distance of 1,190 nautical miles. This phase took place approximately 4 miles north-west of Seckau, Austria. The aircraft then began its enroute descent, which started 22 miles south-west of Sesimbra, Portugal. The descent phase took 14 minutes to complete and covered a distance of 41 nautical miles, with the aircraft decreasing its altitude by 38,173 feet from 39,046 feet above sea level to 873 feet above sea level.
The final approach to runway 20 at LPPT Humberto Delgado Airport (Lisbon Portela Airport) was made from the north-east, with the aircraft heading 207.0 degrees at an altitude of 487 feet above ground level and a distance of 2 nautical miles from the runway. The landing was made on runway 20, which had a length of 10,247 feet. The local weather conditions at the time of landing were characterized by a temperature of 57 degrees Fahrenheit and a wind speed of 10 knots at 240 degrees, resulting in a crosswind of 6 knots and a headwind of 8 knots.
The landing was successful, with the aircraft touching down at a speed of 120 knots and a touchdown distance of 1,099 feet, which accounted for 28% of the runway. The touchdown rate was fair at -218 feet per minute, but the runway touchdown alignment was perfect. The runway rollout alignment was also perfect, and the aircraft taxied to the parking area in 2 minutes, covering less than 1 nautical mile.
In total, the flight covered a distance of 1,322 nautical miles and took 188 minutes to complete, using 49,382 pounds of fuel.
