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.

Speed and pitch

From brake release to the end of the climb, against time, then the takeoff point by point.

Lifted off at 37 kt with 5.8° of pitch.

How to read this

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.

Side view from the start of the roll to 345 ft.

Reached 35 ft with 462 m of runway left; then climbing at 980 fpm on average to 345 ft.

How to read this

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 738 m runway.

Rolled from 44 m in, never more than 1.3 m off the centreline. Airborne 12 % of the way down the runway, before the 75 % line.

How to read this

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 crosswind

Little crosswind (2 kt): nothing to correct for. Touched down with the nose 4° right of the track, wings level.

Wind 225° at 3 kt · 2 kt tail · 2 kt across

How to read this

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 794 m of the approach.

Crossed the threshold at 23 ft, 27 ft below the 50 ft target. Touched down 61 m in, 243 m short of the ideal 305 m.

How to read this

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 794 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 670 fpm at 24 ft to 480 fpm at touchdown. The nose came up 6.5° on the way down.

How to read this

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 794 m runway, to the same scale as the side view.

Touched down 5.5 m right of the centreline, and stayed about there down the rollout, 4.3 m right at the widest.

How to read this

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.
