Know your rotation speed
See Departure Roll
A typical trainer rotates in the mid-50s of knots - a 172 at around 55 KIAS, climbing out at a Vy in the low 70s, though check your own POH rather than memorising Cessna's numbers - and the transferable rule is that Vr sits just above the stall speed in takeoff configuration. Rotate early because "it felt ready" and the aircraft lifts off inside ground effect, where induced drag is reduced, then climbs out of it into more drag. On a marginal-performance day the result is an aircraft that lifts off and then refuses to climb, sagging back towards the runway.

From brake release to the end of the climb, against time, then the takeoff point by point.
Lifted off at 94 kt with 0.9° 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 takeoff, point by point
Side view from the start of the roll to 315 ft.
Reached 35 ft with 1,540 m of runway left; then climbing at 510 fpm on average to 315 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.
Plan view the roll down the 2,295 m runway.
Rolled from 95 m in, drifted left of the centreline, 3.5 m at the widest, and lifted off 1.8 m right, in 5 kn of crosswind from the right. Airborne 25 % 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 1.2 nm, where the final began, to the threshold, never more than 160 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 9× larger than distances along the final.
Inside the 1° band from 1.2 nm, where the final began, to 0.9 nm, then drifted 43 m right between 0.9 and 0.6 nm, then inside the band from 0.6 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.
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.
Slow from 1.2 nm, where the final began, to 0.5 nm (up to −9 kt), then inside the band to the threshold.
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
5 kt across from the left, which takes about 5° of crab to hold the centreline at 58 kt. Touched down with 4° of it still on, wings level.
Wind 060° at 15 kt · 13 kt head · 5 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.
Side view — the last 1,524 m of the approach.
Crossed the threshold at 62 ft, 12 ft above the 50 ft target. Touched down 451 m in, 146 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.
From 59 ft the descent stopped and turned into a climb of 170 fpm before coming down at 140 fpm to touch. The nose came up 2.6° 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 2,295 m runway, to the same scale as the side view.
Touched down on the centreline and drifted to 9.7 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 451 m touchdown sits inside the full-score zone. The 1.23 G arrival bounced.
The rest of the report
The flight began with a departure roll from runway 10 at TNCM Princess Juliana International Airport. The aircraft, a DHC-2 Beaver, accelerated down the runway, covering a distance of 549 meters, which accounted for 24% of the runway's length. The liftoff speed was achieved at 94 knots, marking the start of the aircraft's ascent into the sky.
As the aircraft climbed, it reached a level cruise altitude, where it remained for 8 minutes, covering a distance of 2 nautical miles. This brief period of steady flight allowed the aircraft to stabilize and prepare for its descent back to the airport. The local weather conditions during this time were characterized by a temperature of 28 degrees Celsius and a wind speed of 15 knots from a direction of 179 degrees.
The final approach to runway 10 was initiated from the west, with the aircraft heading towards the airport at a bearing of 85.0 degrees. At an altitude of 237 feet above ground level and 1 nautical mile from the runway, the aircraft began its descent. The landing was executed on runway 10, which had a length of 2,295 meters. The threshold height was slightly above the target, while the threshold speed was slightly below the target at 63 knots.
The touchdown distance was good, covering a distance of 449 meters, which accounted for 28% of the runway's length. The touchdown speed was also within acceptable limits at 58 knots, and the touchdown rate was smooth at -144 feet per minute. The runway touchdown alignment was perfect, indicating a well-executed landing. The local weather conditions during the landing were characterized by a temperature of 27 degrees Celsius and a wind speed of 14 knots from a direction of 60 degrees.
Following the landing, the aircraft taxied to the parking area, covering a distance of less than 1 nautical mile in 1 minute. The total flight distance was 4 nautical miles, and the flight duration was 11 minutes. The aircraft used 14 kilograms of fuel during the flight.
