Avoid steep turns at low altitude
Below a thousand feet the aeroplane is slow, heavy and close to the ground. A steep turn loses lift, raises the stall speed and flattens the climb just when the gradient matters most. A normal turn on course is a rate one — fifteen degrees or so, twenty-five at the outside, this penalty is to acknowledge when a turn has stopped being a turn and become a manoeuvre.

The roll
Liftoff pitch close to a tail strike
The wheels left at 8.5°, 1.0° short of this aircraft's 9.5° tail strike.
The tail can only touch while the main wheels are still on the runway, so the margin that matters is the one at liftoff. Rotate at the rotate speed, at the normal rate, and let the aircraft fly itself off at its own attitude: keep the pull going towards the climb attitude only once the wheels have left. Rotating early, or pulling faster than the aircraft can lift off, is what eats the margin.
Liftoff and climb
Plan view the roll down the 8,991 ft runway.
Rolled from 385 ft in, drifted left of the centreline, 11 ft at the widest, and lifted off 12 ft left. Airborne 60 % 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.
Side view from the start of the roll to the end of Climb 3 at 945 ft.
Reached 35 ft with 2,437 ft of runway left; gear up at 88 ft, inside the 400 ft that gets full marks; then climbing at 2,460 fpm on average to 945 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. The dark stretch of the roll is the run with the nose up and the wheels still on, with its length and time under the runway. The gear-up ring is coloured by its mark. The shaded stretch is Climb 3, scored on its average speed against the target.
Speed and pitch from brake release to the end of the climb, against time.
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 dashed green line is the speed to rotate at for this aircraft at its weight, and the green dot is where the nose started to come up. The grey band is the run between the nose coming up and the wheels leaving the runway. The figures at liftoff are the pitch then and how fast the nose came up, in degrees a second. The rotation detail below draws the rotation against the rates for this aircraft and its tail-strike pitch, where the slope reads properly. The grey dashed line across the pitch is the attitude held from 35 ft to the end: a nose held steady is a climb speed that holds, and the airspeed trace sits directly above it to compare. The shaded stretch is Climb 3, the part of the climb scored on holding the climb speed.
Rotation detail the pitch over the seconds from rotation to 35 ft, where the slope reads properly.
The pitch over the seconds from the nose starting to come up to 35 ft, stretched so the slope reads properly. The green dot is where the nose started up, the grey band runs to the wheels leaving, and the figures at liftoff are the pitch then and how fast the nose came up. The two dashed green lines rising from the rotation point are 2 to 3° a second, the rates airliners are rotated at: a trace steeper than both is a faster rotation, one shallower than both a slower one. The red dashed line is 9.5°, the pitch at which this aircraft's tail touches the runway with the wheels still on it, drawn from rotation to liftoff only: once the wheels leave, every foot climbed adds tail clearance.
Two stabilised approach gates, each with seven checks, where the approach path is 1,000 ft and 500 ft above the runway. They are the approach's score: the checks passed out of the checks that ran.
When the approach was stable
Every check met from 4 nm to the threshold.
Each line is one of the gate checks, run along the whole final rather than only at the gates: green where it would have passed, amber where it would not. The glideslope, centreline and speed lines use the bands in the charts beside this card. The sink rate is allowed what the glideslope needs at your ground speed plus 600 fpm, the wings 10° of bank, and the gear and flap are read from when you moved the levers. The bottom line is green where every check held at once, ignoring blips shorter than 0.2 nm, and the sentence above it says from where it held to the threshold. A ring is a stabilisation gate, where the checks in the table were taken.
The final from 4 nm, with the stabilisation gates on it.
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 100 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, 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. A ring is a stabilisation gate: green when every check there passed, amber with the failed checks named beside it.
Plan distance off the extended centreline, your left at the top, with the 1° band. Sideways distances are drawn 16× larger than distances along the final.
Inside the 1° band all the way from 4 nm, never more than 70 ft off the centreline.
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 39 kt fast at the 1,000 ft gate, closing to 23 at 500 ft and 10 at the threshold.
Inside the speed band all the way, between +4 kt and +7 kt on the approach speed of 154 kt.
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
Excellent landing flare
It lost 1.4 points, mostly for taking only 363 fpm of the sink out.
Touchdown
Rollout
Taxi in
Side view — the last 6,232 ft of the approach.
Began the flare at 28 ft, 183 ft before the threshold; crossed the threshold at 21 ft, 29 ft below the 50 ft target. Touched down 1,216 ft in, 216 ft past the ideal 1,000 ft.
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 6,232 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 570 fpm at the flare to 260 fpm at touchdown. The nose came up 1.4° on the way down. Into the flare at 159 kt, 5 kt over the 154 kt approach speed, and 152 kt at touchdown.
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 6,232 ft of the 10,398 ft runway, to the same scale as the side view.
Touched down 5 ft right of the centreline, and stayed within 7 ft of it down the rollout. Little crosswind (2 kt): nothing to correct for. Touched down straight, wings level.
Wind 250° at 3 kt · 1 kt head · 2 kt across
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 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. The sentence gives the nose against the direction you were actually moving as the wheels touched, and the steepest bank as they touched, the figure the touchdown's Bank tile marks. The rest of it is shown for reading, not marked.
The 1,216 ft touchdown sits inside the full-score zone. The arrival was smooth.
The stop — touchdown to taxi speed.
From 151 kt at touchdown to taxi speed (30 kt) in 61 s, an average deceleration of 0.10 g.
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.

The final approach to runway 30 at KOAK descended from 1,249 ft agl to 47 ft agl in 89 seconds. Stabilisation checks at 1,000 ft and 500 ft above the runway were met for gear down, landing flap, sink rate, glideslope, centreline, speed and wings level. Configuration was landing gear down at 2,715 ft agl at 214 kt; final flap position 6 was selected at 2,234 ft agl at 184 kt.
Landing on runway 30 (runway length 10,398 ft) had a good threshold height and a threshold speed of 158 kt. The flare was described as excellent. Touchdown occurred 1,216 ft down the runway at 152 kt, noted as a little fast, with a fair touchdown rate of minus 262 fpm and very good runway-touchdown alignment. No bounce occurred. Total landing distance was 5,961 ft (57 % of runway) and rollout alignment was perfect. Local weather was 66 °F with a 4 kt wind from 270°, giving a 3 kt headwind and 2 kt cross-wind.
After landing, the aircraft taxied to the parking area for 6 minutes, covering 1 nm. The total flight covered 2,191 nm in 285 minutes and used 79,874 lb of fuel.
