Keep the taxi smooth
See Departure Taxi
Turn speed is limited by lateral load on the tyres and the people in the back, and lateral acceleration goes with the square of speed. On an illustrative 25 m turn radius, 10 kt produces about 0.11 g of side load, while 20 kt produces about 0.43 g. Doubling the speed quadruples the load. That square law is the entire content of the "10 knots in turns" rule, and it tells you why a slightly-too-fast turn feels fine and a moderately-too-fast one throws the cabin crew across the galley.

From brake release to the end of the climb, against time, then the takeoff point by point.
Lifted off at 77 kt with 7.0° 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 865 ft.
Reached 35 ft with 1,430 m of runway left; then climbing at 670 fpm on average to 865 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 2,187 m runway.
Rolled from 85 m in, drifted left of the centreline, 6.1 m at the widest, and lifted off 4.1 m right, in 10 kn of crosswind from the left. Airborne 21 % 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 200 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 3× larger than distances along the final.
Outside the 1° band 3 times; furthest 252 m left at 4.0 nm.
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
Little crosswind (2 kt): nothing to correct for. Touched down with the nose 2° left of the track, wings level.
Wind 150° at 8 kt · 8 kt head · 2 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 55 kt at touchdown to taxi speed (30 kt) in 27 s, an average deceleration of 0.05 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 36 ft, 14 ft below the 50 ft target. Touched down 421 m in, 117 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 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 380 fpm at 34 ft to 70 fpm at touchdown. The nose came up 4.1° 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 2,936 m runway, to the same scale as the side view.
Touched down 7.4 m left of the centreline, and stayed about there down the rollout, 9.4 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 arrow beside the runway is the crosswind, pointing the way the air was moving, so it pushed the aircraft that way.
The 421 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The flight in the Douglas DC-3 started with a 6-minute taxi from the parking area to the runway at LECO A Coruña Airport. The departure roll on runway 21 covered a distance of 393 meters, which was 18% of the total runway length. The liftoff speed was 77 knots, with a local weather report indicating a temperature of 21 °C and winds at 13 knots coming from 150°, resulting in a crosswind of 11 knots and a headwind of 6 knots.
The enroute climb began overhead Culleredo in Galicia, Spain, climbing from 1,230 feet above sea level to 3,497 feet above sea level. This climb covered a distance of 8 nautical miles and took 4 minutes. The enroute descent started 3 miles north of Ordes, descending from 3,488 feet to 2,802 feet in 2 minutes, covering 5 nautical miles. The enroute level cruise started 2 miles south of Ordes, lasting 2 minutes and covering 5 nautical miles.
The final approach to runway 17 at LEST Santiago-Rosalía de Castro Airport was from the north, heading 166.0° at 3 nautical miles and 1,264 feet above ground level. The landing on runway 17 at LEST Santiago-Rosalía de Castro Airport, which has a runway length of 2,936 meters, had a good threshold height and a slightly below target threshold speed of 73 knots. The touchdown distance was good at 421 meters, with a touchdown speed of 61 knots and an excellent touchdown rate of -70 feet per minute. However, the runway touchdown position was slightly misaligned by 7.4 meters from the centerline. The local weather at the time of landing was 17 °C, with winds at 8 knots coming from 150°, resulting in a crosswind of 2 knots and a headwind of 8 knots. The total landing distance was 985 meters, which was 34% of the total runway length. The runway rollout alignment was slightly misaligned by 9.4 meters from the centerline.
After landing, the taxiing to the parking area from the runway took 2 minutes and covered less than 1 nautical mile. The total flight distance was 25 nautical miles, taking 20 minutes, and the flight used 68 kilograms of fuel.
