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.

From brake release to the end of the climb, against time, then the takeoff point by point.
Lifted off at 77 kt with 5.4° of pitch.
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.
The takeoff, point by point
Side view from the start of the roll to the end of Climb 3 at 814 ft.
Reached 35 ft with 3,546 ft of runway left; then climbing at 1,780 fpm on average to 814 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 shaded stretch is Climb 3, scored on its average speed against the target.
Plan view the roll down the 4,944 ft runway.
Rolled from 438 ft in, never more than 3 ft off the centreline. Airborne 21 % 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.
The final from 4 nm.
Profile height against the 3° glideslope, with its 2° band in green.
Inside the glideslope band from 1.2 nm, where the final began, to the threshold, never more than 80 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.
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 1,100 ft right of the centreline at 1.2 nm, then inside the band from 0.6 nm to the threshold.
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 78 kt fast at the 1,000 ft gate, closing to 48 at 500 ft and 10 at the threshold.
Inside the speed band all the way, between −2 kt and +7 kt on the approach speed of 80 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
Touchdown
8 kt across from the left, which takes about 7° of crab to hold the centreline at 62 kt. Touched down with 7° of it still on, wings level.
Wind 110° at 15 kt · 14 kt head · 8 kt across
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.
From 44 kt at touchdown to taxi speed (30 kt) in 12 s, an average deceleration of 0.06 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.
Side view — the last 5,000 ft of the approach.
Crossed the threshold at 26 ft, 24 ft below the 50 ft target. Touched down 1,695 ft in, 695 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 5,000 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 460 fpm at 24 ft to 10 fpm at touchdown. The nose came up 4.9° on the way down.
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 5,000 ft of the 8,200 ft runway, to the same scale as the side view.
Touched down on the centreline, and stayed within 9 ft of it down the rollout.
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.
Touched down 1,695 ft past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The Velocity XL aircraft departed from runway 12 at YPJT Perth Jandakot Airport, covering a takeoff distance of 671 feet, which accounted for 14% of the runway. The liftoff speed was 78 knots, and the local weather conditions at the time of departure were characterized by a temperature of 52 degrees Fahrenheit and a wind speed of 8 knots at 110 degrees.
As the aircraft climbed out of Jandakot, it began its enroute climb, reaching an altitude of 21,517 feet above sea level in 12 minutes, covering a distance of 30 nautical miles. The climb started from an initial altitude of 939 feet above sea level, resulting in an increase of 20,579 feet.
