MY FS FLIGHTS
Flight Score
Arrival
Fly a slightly steeper approach path to cross the threshold at 50 ft agl instead of 58 ft agl.
What happened: The aircraft crossed the threshold at 58 ft agl against a 50 ft agl target, above the normal profile. This fault pattern is often followed by a long touchdown beyond the target point, and here the aircraft touched down at 1,040 m against a 457 m target.
Watch for: Radio altimeter against the 50 ft threshold crossing target on short final.
Ground effect becomes significant below about one wingspan of height. A Cessna 172, with a 36 ft span, enters ground effect at flare height - the float it feels in the hold-off is ground effect arriving on cue. An A320, with a span around 117 ft, has been in ground effect since before the threshold and there is no sudden cushion to feel, only a gradual reduction in induced drag that lengthens any float you allow.

The roll
A clean takeoff
Rotated at 158 kt against the 163 kt rotate speed, the nose rising at 1.5° a second, then held 11.7° from 35 ft, within 4.1° top to bottom.
Rotated on speed at a steady rate, and the climb attitude held. This is the takeoff to repeat: the same speed check, the same pull, the same attitude.
Liftoff and climb
Plan view the roll down the 3,623 m runway.
Rolled from 121 m in, drifted right of the centreline, 3.4 m at the widest, and lifted off 2.7 m right. Airborne 47 % 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 897 ft.
Reached 35 ft with 1,546 m of runway left; gear up at 232 ft, inside the 400 ft that gets full marks; then climbing at 2,310 fpm on average to 897 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 1.5 to 2.3° a second, the middle half of rotation rates flown by other Airbus A350-900 pilots over the last 180 days (59 takeoffs); the grey pair are 2 to 3° a second, the rates airliners are rotated at. A trace steeper than both green lines is a faster rotation than most, one shallower than both a slower one.
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 10 ft above the slope.
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. 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 28× larger than distances along the final.
Inside the 1° band all the way from 4 nm, never more than 13 m 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 34 kt fast at the 1,000 ft gate, closing to 21 at 500 ft and 10 at the threshold.
Inside the speed band all the way, between +0 kt and +8 kt on the approach speed of 137 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
The flare tracked the target profile exactly
The aircraft floated down the runway before touching. Touchdown was 1,040 m past the threshold. Threshold speed was not the cause here - hold the aim point on the approach and let the aircraft settle rather than holding it off, and the touchdown comes back to the numbers.
Touchdown
Rollout
Side view — the last 1,854 m of the approach.
Crossed the threshold at 57 ft, close to the 50 ft target; began the flare at 24 ft. Touched down 1,040 m in, 735 m past the ideal 305 m.
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 1,854 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 450 fpm at the flare to 140 fpm at touchdown. The nose came up 1.9° on the way down. Into the flare at 137 kt, on the 137 kt approach speed, and 127 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 1,854 m of the 4,065 m runway, to the same scale as the side view.
Touched down on the centreline, and stayed within 1.1 m of it down the rollout. No crosswind: nothing to correct for. Touched down with the nose 2° right of the track, wings level.
Wind 087° at 1 kt · 1 kt head · 0 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 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.
Touched down 1,040 m past the threshold — beyond the full-score zone. The arrival was smooth.
The stop — touchdown to taxi speed.
From 126 kt at touchdown to taxi speed (30 kt) in 19 s, an average deceleration of 0.26 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.
