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 146 kt with 3.5° 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 985 ft.
Reached 35 ft with 5,448 ft of runway left; then climbing at 1,810 fpm on average to 985 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 248 ft in, drifted 13 ft right of the centreline and was back on it to lift off. 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.
Inside the glideslope band from 1.8 nm, where the final began, to the threshold, never more than 140 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 2,630 ft left of the centreline at 1.8 nm, then inside the band from 1.0 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 121 kt. Touched down with 2° of it still on, wings level.
Wind 294° at 5 kt · 4 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.
Side view — the last 5,422 ft of the approach.
Crossed the threshold at 39 ft, 11 ft below the 50 ft target. Touched down 2,281 ft in, 1,281 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 5,422 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 400 fpm at 39 ft to 80 fpm at touchdown. The nose came up 3.5° 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 5,422 ft of the 7,721 ft runway, to the same scale as the side view.
Touched down on the centreline and drifted to 24 ft right on 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.
Touched down 2,281 ft past the threshold — beyond the full-score zone. The 1.18 G arrival bounced 4 times.
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 02 at LPPT Humberto Delgado Airport (Lisbon Portela Airport). The takeoff distance was 3,770 feet, which is 37% of the runway length. The aircraft lifted off at a speed of 146 knots.
The local weather conditions at the time of takeoff were characterized by a temperature of 53°F and a wind speed of 5 knots from a direction of 240°. This resulted in a crosswind of 3 knots and a tailwind of 4 knots. The aircraft then began its enroute climb, which started overhead Camarate, a location in the Distrito de Lisboa, Portugal. The climb took the aircraft from an altitude of 1,371 feet above sea level to 36,912 feet above sea level, an increase of 35,540 feet, in just 4 minutes and covering a distance of 70 nautical miles.
The enroute level cruise phase of the flight began 8 miles east of Pombal, a location in the Distrito de Leiria, Portugal. This phase lasted for 26 minutes and covered a distance of 807 nautical miles. The aircraft then began its enroute descent, which started 1 mile northeast of Corwen, a location in Denbighshire, Wales. The descent took the aircraft from an altitude of 35,492 feet above sea level to 346 feet above sea level, a decrease of 35,146 feet, in 10 minutes and covering a distance of 49 nautical miles.
The final approach to runway 25 at EGNO Warton Aerodrome was made from the east, with the aircraft heading 251.0° at 1 nautical mile and 291 feet above ground level. The landing was made on runway 25, which has a length of 7,721 feet. The local weather conditions at the time of landing were characterized by a temperature of 35°F and a wind speed of 5 knots from a direction of 293°. This resulted in a crosswind of 4 knots and a headwind of 4 knots.
The landing was successful, with the touchdown point being 899 feet beyond the touchdown zone. The touchdown speed was 121 knots, which was good, and the touchdown rate was excellent at -82 feet per minute. The runway touchdown alignment was perfect. The total landing distance was 5,140 feet, which is 67% of the runway length. The runway rollout alignment was very good.
The final phase of the flight involved taxiing to the parking from the runway, which took approximately 1 minute and covered less than 1 nautical mile. The total flight distance was 930 nautical miles, and the flight duration was 45 minutes. The aircraft used a total of 32,437 pounds of fuel during the flight.
