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 72 kt with 8.9° 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 693 ft.
Reached 35 ft with 2,122 m of runway left; then climbing at 760 fpm on average to 693 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 2,990 m runway.
Rolled from 205 m in, drifted 13 m left of the centreline and was back on it to lift off. Airborne 20 % 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 4 nm to the threshold, never more than 170 ft below 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 7× larger than distances along the final.
Inside the 1° band from 4 nm to 1.7 nm, then drifted 58 m left between 1.7 and 1.5 nm, then back inside it from 1.5 to 0.9 nm, then 35 m left of it from 0.9 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
Calm: nothing to correct for. Touched down with the nose 3° right of the track, wings level.
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 72 kt at touchdown to taxi speed (30 kt) in 20 s, an average deceleration of 0.11 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 1,524 m of the approach.
Crossed the threshold at 26 ft, 24 ft below the 50 ft target. Touched down 230 m in, 75 m short of 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 1,524 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 400 fpm at 25 ft to 160 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 1,524 m of the 2,191 m runway, to the same scale as the side view.
Touched down 8.2 m left of the centreline, and stayed about there down the rollout, 8.4 m 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 230 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The flight in the Douglas DC-3 from LELN León Airport to LEAS Asturias Airport was overall successful. The taxiing from the parking to the runway was smooth, taking 4 minutes to cover less than 1 nm. The departure roll on runway 05 at LELN was uneventful, with a takeoff distance of 1,297 ft and a liftoff speed of 72 kn. The local weather conditions at the time of departure included a temperature of 42 °F and a wind of 4 kn at 63 °, resulting in a 1 kn crosswind and 4 kn headwind.
The enroute climb started 1 mile southwest of San Andres del Rabanedo, climbing from 3,708 ft to 13,467 ft in 15 minutes, covering 3 nm. The level cruise during the enroute climb lasted 2 minutes, covering 6 nm. The subsequent descent started overhead Santa Maria de Ordas, descending from 13,454 ft to 10,879 ft in 4 minutes, covering 16 nm.
Another level cruise during the descent lasted 7 minutes, covering 20 nm. The final descent began 2 miles northwest of Castandiello, bringing the aircraft from 10,265 ft to 3,124 ft in 7 minutes, covering 15 nm. The next level cruise segment started 2 miles southwest of Gijon and lasted 4 minutes, covering 5 nm. The final descent segment started 2 miles southeast of Corvera de Asturias, descending from 3,093 ft to 1,629 ft in 4 minutes, covering 5 nm.
The final approach to runway 29 at LEAS Asturias Airport was on point, with the aircraft positioned correctly. The landing on runway 29 was successful, with a slight misalignment of the touchdown position from the centerline. The touchdown speed, rate, and distance were all within acceptable limits. The total landing distance was 2,401 ft, accounting for 33% of the runway length.
After landing, the taxiing from the runway to the parking area took 1 minute to cover less than 1 nm. The total flight distance from LELN to LEAS was 77 nm, taking 53 minutes and using 559 lbs of fuel. The journey was completed efficiently and safely, showcasing the capabilities of the Douglas DC-3 aircraft.
