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 140 kt with 4.4° 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 361 ft.
Reached 35 ft with 3,622 ft of runway left; then climbing at 1,080 fpm on average to 361 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 7,721 ft runway.
Rolled from 4,651 ft in, drifted 61 ft left of the centreline and was back on it to lift off, in 8 kn of crosswind from the right. Airborne 39 % 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 3.8 nm, where the final began, to 3.3 nm (up to 540 ft over), then back on it to 0.3 nm, then low to the threshold (up to 50 ft under).
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 3,840 ft left of the centreline at 3.8 nm, then inside it from 2.8 to 2.1 nm, then drifted 230 ft right between 2.1 and 1.7 nm, then inside the band from 1.7 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
3 kt across from the left, which takes about 2° of crab to hold the centreline at 113 kt. Touched down straight - the crab taken out before the wheels touched, wings level.
Wind 311° at 15 kt · 14 kt head · 3 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 93 kt at touchdown to taxi speed (30 kt) in 21 s, an average deceleration of 0.15 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 20 ft, 30 ft below the 50 ft target. Touched down 908 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 360 fpm at 19 ft to 130 fpm at touchdown. The nose came up 2.2° 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 first 5,000 ft of the 7,102 ft runway, to the same scale as the side view.
Touched down on the centreline, and stayed within 3 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 908 ft touchdown sits inside the full-score zone. The 1.14 G arrival bounced.
The rest of the report
The flight began with the B-2 Spirit taxiing from the parking area to the runway at EGNO Warton Aerodrome, taking approximately 2 minutes and covering less than 1 nautical mile. The aircraft then departed from runway 25, with a takeoff distance of 1,646 feet, which accounted for 21% of the runway. The liftoff speed was 140 knots.
As the aircraft took to the skies, it encountered local weather conditions of 44°F temperature, with a wind speed of 17 knots at 290°. The crosswind was 10 knots, while the headwind was 13 knots. The enroute climb started overhead Warton, with the aircraft ascending from 458 feet above sea level to 37,675 feet, an increase of 37,217 feet in just 15 minutes, covering a distance of 78 nautical miles.
The enroute level cruise began 11 miles west of Port Erin, on the Isle of Man, and lasted for 328 minutes, covering a distance of 2,548 nautical miles. The aircraft then started another enroute climb, this time from 38,341 feet to 44,022 feet, an increase of 5,681 feet in just 6 minutes, covering 50 nautical miles. The climb took place 4 miles northeast of Shelburne, New Hampshire, United States.
Following the climb, the aircraft entered another enroute level cruise, this time starting 2 miles west of the NH36 Weeks Medical Center Heliport in Lancaster, New Hampshire, and lasting for 4 minutes, covering 36 nautical miles. The aircraft then began its descent, starting overhead the NH03 Granite Heliport in Hudson, New Hampshire, and descending from 43,923 feet to 10,423 feet, a decrease of 33,500 feet in 13 minutes, covering 89 nautical miles.
The enroute level cruise resumed once again, this time starting 2 miles southeast of Baltic, Connecticut, and lasting for 4 minutes, covering 22 nautical miles. The aircraft then started its final descent, beginning 2 miles northeast of Charlestown, Rhode Island, and descending from 10,130 feet to 935 feet, a decrease of 9,194 feet in just 4 minutes, covering 13 nautical miles.
The final approach to runway 34 at KOQU Quonset State Airport was made from the southeast, with the aircraft heading 326.0° at 2 nautical miles and 895 feet above ground level. The landing was successful, with the aircraft touching down on the runway at a speed of 113 knots and a touchdown distance of 901 feet. The touchdown rate was smooth at -128 feet per minute, and the runway touchdown alignment was perfect.
The local weather conditions at the time of landing were 26°F temperature, with a wind speed of 15 knots at 310°. The crosswind was 4 knots, while the headwind was 14 knots. The total landing distance was 2,350 feet, accounting for 33% of the runway. The runway rollout alignment was also perfect.
The aircraft then taxied to the parking area from the runway, taking approximately 1 minute and covering less than 1 nautical mile. The total flight distance was 2,840 nautical miles, taking a total of 383 minutes, and the aircraft used 59,413 pounds of fuel during the flight.
