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 80 kt with 6.8° 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 995 ft.
Reached 35 ft with 2,003 m of runway left; then climbing at 460 fpm on average to 995 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 3,364 m runway.
Rolled from 20 m in, drifted 12 m left of the centreline and was back on it to lift off. Airborne 30 % 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 final from 4 nm.
Profile height against the 3° glideslope, with its 1° band in green.
Inside the glideslope band from 4 nm to the threshold, never more than 70 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, 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 15× larger than distances along the final.
Inside the 1° band all the way from 4 nm, never more than 25 m off the centreline.
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
8 kt across from the left, which takes about 7° of crab to hold the centreline at 63 kt. Touched down with the nose 11° into wind, wings level.
Wind 320° at 10 kt · 5 kt head · 8 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 61 kt at touchdown to taxi speed (30 kt) in 94 s, an average deceleration of 0.02 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 2,263 m of the approach.
Crossed the threshold at 26 ft, 24 ft below the 50 ft target. Touched down 370 m in, 65 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 2,263 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 360 fpm at 26 ft to 120 fpm at touchdown. The nose came up 3.3° 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 2,263 m of the 3,123 m runway, to the same scale as the side view.
Touched down 9.1 m right of the centreline and drifted to 16 m left on the rollout, back to 1.2 m left 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 370 m touchdown sits inside the full-score zone. The 1.18 G arrival bounced.
The rest of the report
The flight in the Douglas DC-3 began with a 13-minute taxi from the parking area to the runway at LEMD Adolfo Suárez Madrid–Barajas Airport. The departure roll on runway 36L covered 4 nm and the takeoff distance was 989 m, with a liftoff speed of 80 kn. The local weather at the time of departure was 11 °C with a wind speed of 0 kn at 172°.
The enroute climb started east of San Sebastian de los Reyes, climbing from 2,987 ft to 8,934 ft, covering 15 nm in 8 minutes. The level cruise segment started near El Vellon for 2 minutes, covering 6 nm. Another climb commenced over Guadalix de la Sierra, increasing altitude from 9,573 ft to 10,875 ft in 2 minutes over 5 nm.
During the 81-minute level cruise segment that followed, the aircraft covered 221 nm north east of Manzanares el Real. The descent began south east of LPMO Morargil Airfield Montargil, descending from 10,999 ft to 7,705 ft over 13 nm in 4 minutes. The next level cruise segment lasted 32 minutes, covering 65 nm south of LPMM Pista do Ciborro Montemor-o-Novo.
Further descents took place near Cascais and Charneca de Caparica, before making the final approach to runway 02 at LPPT Humberto Delgado Airport from the south. The landing on runway 02 was smooth, with a touchdown speed of 63 kn and a touchdown rate of -119 ft/m. The touchdown position was slightly misaligned by 9.1 m from the centerline.
After landing, the aircraft used a total landing distance of 2,156 m, 69% of the runway. The runway rollout alignment was slightly off by 17.9 m from the centerline. Taxing back to the parking area from the runway took 3 minutes, covering less than 1 nm.
Overall, the flight covered a distance of 362 nm, lasting 160 minutes and consuming 640 kg of fuel.
