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 66 kt with 4.1° 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 94 ft. The distance scale changes past the runway end.
Reached 35 ft 697 m past the runway end.
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 424 m runway.
Rolled from 311 m in, drifted right of the centreline, 6 m at the widest, and lifted off 6.2 m right. Airborne 105 % of the way down the runway, past 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.
Low from 1.8 nm, where the final began, to the threshold (up to 490 ft under).
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 699 m left of the centreline at 1.8 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 +19 kt on the approach speed of 68 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 (1 kt): nothing to correct for. Touched down with the nose 5° left of the track, wings level.
Wind 269° at 2 kt · 2 kt head · 1 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 68 kt at touchdown to taxi speed (30 kt) in 10 s, an average deceleration of 0.22 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 653 m of the approach.
Crossed the threshold at 17 ft, 33 ft below the 50 ft target. Touched down 126 m in, 178 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 653 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.
From 17 ft the descent stopped and turned into a climb of 660 fpm before coming down at 660 fpm to touch. The nose came up 3.4° 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 full 653 m runway, to the same scale as the side view.
Touched down 4.7 m left of the centreline, and stayed about there down the rollout, 6.3 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 126 m touchdown sits inside the full-score zone. The 1.40 G arrival bounced.
The rest of the report
The flight began with a departure roll from runway 19 at AYNH Nahu Airstrip. The Kodiak 100 aircraft accelerated down the runway, covering a distance of 136 meters, which accounted for 32% of the runway's length. The aircraft lifted off at a speed of 66 knots, marking the start of its journey.
As the aircraft took to the skies, it encountered local weather conditions of 21 degrees Celsius and a gentle wind of 2 knots at 269 degrees. The crosswind was minimal, at 2 knots, while the tailwind was a mere 1 knot. The enroute level cruise phase began shortly after takeoff, with the aircraft flying overhead AYNH Nahu Airstrip Gumbarami in Madang Province, Papua New Guinea. This brief phase lasted less than a minute and covered a distance of less than 1 nautical mile.
The enroute climb phase followed, during which the aircraft ascended from 7,212 feet above sea level to 14,991 feet, an increase of 7,778 feet in just 6 minutes. This climb covered a distance of 13 nautical miles. The aircraft then entered another level cruise phase, this time flying 6 miles south of PZ67 Mibu Airstrip in Madang Province. This phase lasted 3 minutes and covered a distance of 10 nautical miles.
As the aircraft approached its destination, it began its enroute descent phase, starting 3 miles west of AYTP Tep Tep Airport Teptep in Madang Province. The aircraft descended from 15,000 feet above sea level to 6,819 feet, a decrease of 8,181 feet in 7 minutes, covering a distance of 4 nautical miles.
The final approach to runway 30 at AYTP Tep Tep Airport was made from the southeast, with the aircraft flying at a heading of 305.0 degrees and 1 nautical mile from the runway. The aircraft touched down on the runway at a speed of 60 knots, with a touchdown distance of 124 meters. The touchdown rate was perfect at 659 feet per minute, and the runway touchdown position was slightly misaligned by 4.7 meters from the centerline.
The local weather conditions at the time of landing were the same as those encountered during takeoff, with a temperature of 21 degrees Celsius and a gentle wind of 2 knots at 269 degrees. The crosswind was minimal, at 1 knot, while the headwind was 2 knots. The total landing distance was 335 meters, accounting for 51% of the runway's length. The runway rollout alignment was very good, indicating a smooth and controlled landing.
In conclusion, the flight was a successful one, with the aircraft completing a total distance of 29 nautical miles in 21 minutes, using 43 kilograms of fuel in the process. The flight crew demonstrated excellent piloting skills, navigating the aircraft through various phases of flight with precision and control.
