See Pattern Base Leg

Bank angle in the pattern is conventionally kept to 20 to 30 degrees, and the base-to-final turn is where that convention earns its keep. Stall speed rises with bank because the wing must produce more lift in a turn. Roughly 7 per cent higher at 30 degrees, about 19 per cent at 45, and around 40 per cent at 60. At 65 kt on base you don't have much margin to spend steepening a turn to salvage an overshoot.

Lifted off at 68 kt with 4.4° 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 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.

How to read this

The lap from above, with the landing direction to the left: the opposite of the runway drawings. The wide pale-blue line is a textbook circuit for your downwind speed - the downwind a mile out for every 100 kt, every turn at 30° of bank - and your track is drawn over it, each leg in the colour of its mark. The numbers are the four turns, the same as on the profile and the cards below. The 45° line from the threshold is the usual point to turn onto base.

How to read this

The same lap straightened out, so the height and the bank can be read together. Each shaded stretch is a turn, numbered as on the plan. The green box is circuit height, 1,000 ft, on the downwind. The amber line is 30° of bank, and a turn's steepest bank shows red above 32°. "Turn crosswind from" is the lowest height to start the first turn at.

Each lap slightly wider and higher than the last, because you're unconsciously using the previous lap as your reference instead of the runway and the numbers. Invisible lap to lap, unmistakable across ten. This is the failure that only measurement catches, because your memory of lap three is gone by lap eight.

Descending on downwind. Power comes back abeam, the aircraft isn't re-trimmed, your eyes are outside judging the turn point, and 100 ft leaks away before base. Shows up as a low gate 2, and everything after it is a scramble.

Steep: 37° of bank.

Bank angle in the pattern is conventionally kept to 20 to 30 degrees, and the base-to-final turn is where that convention earns its keep. Stall speed rises with bank because the wing must produce more lift in a turn. Roughly 7 per cent higher at 30 degrees, about 19 per cent at 45, and around 40 per cent at 60. At 65 kt on base you don't have much margin to spend steepening a turn to salvage an overshoot.

Steep: 43° of bank.

From abeam the threshold, fly roughly 30 to 45 seconds before turning base, in nil wind at 172 speeds. Treat that as a starting value and calibrate it. If your finals keep coming out at 400 ft instead of 500, add a few seconds. Then adjust for wind, roughly a second per knot of headwind on final (a headwind on final is a tailwind on downwind, carrying you further from the field per second).

The crosswind

No crosswind: nothing to correct for. Touched down straight, wings level.

Wind 270° at 1 kt · 1 kt tail · 0 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 56 kt at touchdown to taxi speed (30 kt) in 9 s, an average deceleration of 0.16 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 1,161 m of the approach.

Crossed the threshold at 30 ft, 20 ft below the 50 ft target. Touched down 335 m in, close to 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 1,161 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 600 fpm at 32 ft to 50 fpm at touchdown. The nose came up 4.5° 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.
