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 81 kt with 4.8° 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 999 ft. The distance scale changes past the runway end.
Reached 35 ft with 367 m of runway left; then climbing at 1,160 fpm on average to 999 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 1,027 m runway.
Rolled from 73 m in, drifted 13 m left of the centreline and was back on it to lift off. Airborne 47 % 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 2° band in green.
Inside the glideslope band from 0.6 nm, where the final began, to the threshold, never more than 60 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.
Joined 280 m left of the centreline at 0.6 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.
Speed against the approach speed. The green band runs from 5 kt slow to 78 kt fast at the 1,000 ft gate, closing to 48 at 500 ft and 10 at the threshold.
Inside the speed band all the way, between −1 kt and +11 kt on the approach speed of 76 kt.
Your indicated airspeed down the final, against the approach speed for this aircraft at its landing weight. The band allows 5 kt slow and more on the fast side further out, closing as you get lower, because the speed is expected to come off on the way down. The figures are knots above (+) or below (−) the approach speed.
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 270° at 2 kt · 0 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 79 kt at touchdown to taxi speed (30 kt) in 12 s, an average deceleration of 0.23 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 1,027 m of the approach.
Crossed the threshold at 11 ft, 39 ft below the 50 ft target. Touched down 151 m in, 154 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 1,027 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 320 fpm at 10 ft to 90 fpm at touchdown. The pitch barely changed.
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 full 1,027 m runway, to the same scale as the side view.
Touched down on the centreline and drifted to 8.1 m left 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.
The 151 m touchdown sits inside the full-score zone. The 1.23 G arrival bounced 2 times.
The rest of the report
The flight began with a departure roll from runway 34 at KFHR Friday Harbor Airport. The Pesim FPV Drone Racer took off with a takeoff distance of 425 meters, which accounted for 41% of the runway. The liftoff speed was 81 knots, and the local weather conditions at the time were a temperature of 16 degrees Celsius and a wind speed of 2 knots from 270 degrees, resulting in a 2-knot crosswind and a 0-knot headwind.
As the drone climbed away from the airport, it began its enroute climb, which started overhead Friday Harbor. The drone climbed from an altitude of 1,129 feet above sea level to 1,599 feet above sea level, an increase of 470 feet in just 1 minute, while covering a distance of 1 nautical mile. Following the climb, the drone entered a level cruise phase, which lasted for 3 minutes and covered a distance of 3 nautical miles, 1 mile north-west of Friday Harbor.
The final approach to runway 34 at KFHR Friday Harbor Airport was initiated from the south, with the drone heading 358.0 degrees at an altitude of 389 feet above ground level and a distance of 1 nautical mile from the runway. However, the drone was forced to execute a go-around at 0 feet above ground level, likely due to a loss of altitude or a navigation error.
The drone subsequently landed on runway 34, with a threshold speed that was well above the target speed of 84 knots. The touchdown distance was good at 151 meters, but the touchdown speed was a little fast at 79 knots. The touchdown rate was excellent at -93 feet per minute, and the runway touchdown alignment was perfect. The local weather conditions at the time of landing were a temperature of 15 degrees Celsius and a wind speed of 2 knots from 270 degrees, resulting in a 2-knot crosswind and a 0-knot headwind.
The total landing distance was 454 meters, which accounted for 44% of the runway. However, the runway rollout alignment was slightly misaligned by 9.8 meters from the centerline. The taxiing to the parking area from the runway took less than 1 minute and covered a distance of less than 1 nautical mile.
In total, the flight distance was 8 nautical miles, and the flight duration was 12 minutes. The drone used 3 kilograms of fuel during the flight.
