Smooth the climb

See Departure Climb 1

Pull to 15 degrees at one rate and you get a clean liftoff, pull to the same 15 degrees at twice the rate and you get an overshoot, a push, and an oscillation through the first few hundred feet. The type-general rule of thumb is a rotation rate of about 2 to 3 degrees per second, which means roughly five to seven seconds from starting the pull to reaching the initial climb attitude of around 15 degrees nose-up. Count it out loud during your next takeoff and you will almost certainly discover you have been rotating in two seconds flat.

The approach to KBOS 15R

The final from 4 nm.

Profile height against the 3° glideslope, with its 1° band in green.

Inside the glideslope band from 4 nm to the threshold, never more than 30 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, 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 216 m right of the centreline, then inside the band from 1.1 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

4 kt across from the left, which takes about 2° of crab to hold the centreline at 134 kt. Touched down with 2° of it still on, wings level.

Wind 110° at 10 kt · 9 kt head · 4 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.

The stop

From 126 kt at touchdown to taxi speed (30 kt) in 34 s, an average deceleration of 0.15 g.

How to read this

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 1,673 m of the approach.

Crossed the threshold at 40 ft, close to the 50 ft target. Touched down 439 m in, 134 m past 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 1,673 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 730 fpm at 41 ft to 260 fpm at touchdown. The nose came up 1.6° 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 first 1,673 m of the 2,804 m runway, to the same scale as the side view.

Touched down on the centreline, and stayed within 2.9 m of it down 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. The arrow beside the runway is the crosswind, pointing the way the air was moving, so it pushed the aircraft that way.
