Monitor your speed

See Enroute Climb

Below 10,000 ft you are typically limited to 250 kt indicated (a US rule that much of the world mirrors in some form, though not universally). This forces a deceleration around 10,000 ft whether the profile wants one or not, so plan for it rather than discovering it.

Speed and pitch

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

Lifted off at 71 kt with 2.9° 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. The shaded stretch is Climb 3, the part of the climb scored on holding the climb speed.

Side view from the start of the roll to the end of Climb 3 at 985 ft. The distance scale changes past the runway end.

Reached 35 ft with 1,077 ft of runway left; then climbing at 1,340 fpm on average to 985 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. The shaded stretch is Climb 3, scored on its average speed against the target.

Plan view the roll down the 2,548 ft runway.

Rolled from 145 ft in, drifted right of the centreline, 22 ft at the widest, and lifted off 22 ft right, in 8 kn of crosswind from the right. Airborne 41 % 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 approach to U81 34

The final from 4 nm.

Profile height against the 3° glideslope, with its 2° band in green.

Inside the glideslope band from 1.0 nm, where the final began, to the threshold, never more than 170 ft above the slope.

How to read this

Your height above the runway against the distance still to go. The glideslope is the steady descent path to the aiming point, 1,000 ft 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 1,500 ft left of the centreline at 1.0 nm, then 230 ft right of it from 0.6 nm to the threshold.

How to read this

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.

The crosswind

No wind recorded: nothing to correct for. Touched down with the nose 9° left of the track, 2° of bank.

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 4,426 ft of the approach.

Crossed the threshold at 63 ft, 13 ft above the 50 ft target. Touched down 2,953 ft in, 1,953 ft past the ideal 1,000 ft.

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 4,426 ft across. The dashed line is the ideal, 50 ft over the threshold and down 1,000 ft 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 1,020 fpm at 88 ft to 100 fpm at touchdown. The nose came up 3.3° 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 4,426 ft runway, to the same scale as the side view.

Touched down 30 ft right of the centreline, and steered back to 9 ft left by the end of the rollout.

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.
