MY FS FLIGHTS
Flight Score
Arrival
Fly a slightly steeper approach path to cross the threshold at 50 ft agl instead of 62 ft agl.
What happened: The aircraft crossed the threshold at 62 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 947 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.

From brake release to the end of the climb, against time, then the takeoff point by point.
Rotated at 137 kt, 7 kt below the 144 kt target, and lifted off at 156 kt 4.5 s later, the nose coming up at 2.0° a second. Climb 3 held close to its 179 kt target, at 177 kt on average.
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 figures at liftoff are the pitch then and how fast the nose came up, in degrees a second. 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 839 ft.
Reached 35 ft with 1,189 m of runway left; gear up at 83 ft, inside the 400 ft that gets full marks; then climbing at 2,780 fpm on average to 839 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 gear-up ring is coloured by its mark. The shaded stretch is Climb 3, scored on its average speed against the target.
Plan view the roll down the 2,690 m runway.
Rolled from the start of the runway, drifted left of the centreline, 5.5 m at the widest, and lifted off 5.6 m left. Airborne 45 % 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 arrow beside the runway is the crosswind, pointing the way the air was moving, so it pushed the aircraft that way.
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 50 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, 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 17× larger than distances along the final.
Inside the 1° band all the way from 4 nm, never more than 22 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 20 at 500 ft and 10 at the threshold.
Inside the speed band all the way, between +7 kt and +10 kt on the approach speed of 135 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
The flare tracked the target profile exactly. The aircraft floated down the runway before touching. Touchdown was 947 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.
No crosswind: nothing to correct for. Touched down straight, wings level.
Wind 340° at 6 kt · 5 kt head · 0 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 122 kt at touchdown to taxi speed (30 kt) in 33 s, an average deceleration of 0.15 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 1,989 m of the approach.
Crossed the threshold at 62 ft, 12 ft above the 50 ft target; began the flare at 41 ft. Touched down 947 m in, 642 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 1,989 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 620 fpm at the flare to 120 fpm at touchdown. The nose came up 2.2° 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 1,989 m of the 3,595 m runway, to the same scale as the side view.
Touched down 5.7 m left of the centreline, and steered back to 0.3 m left by the end of 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.
Touched down 947 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The Boeing 737-800 departed EDDL Düsseldorf Airport on runway 23L. The take-off roll was 1,207 m, using 45 % of the runway, and rotation occurred at 137 kt. Local weather was 11 °C, wind 2 kt from 140°, with a 2 kt cross-wind and no head-wind.
Initial climb to 1,000 ft agl took 16 seconds at an average rate of 2,580 fpm, reaching 177 kt at the top of the climb. The aircraft then climbed from 1,049 ft asl to 34,820 ft asl in 20 minutes, covering 132 nm while remaining overhead Düsseldorf.
Cruise was maintained at 35,000 ft asl for 25 minutes, covering 184 nm, beginning about 1 mile south of Alzenau in Unterfranken. Descent began from 34,255 ft asl to 6,223 ft asl in 25 minutes, covering 146 nm, starting overhead Budetice. A level segment at 5,900 ft asl lasted 8 minutes over 36 nm, beginning 1 mile south-west of Leopoldsdorf im Marchfelde. A further descent from 5,597 ft asl to 1,883 ft asl took 6 minutes over 19 nm, beginning 3 miles south-west of Illmitz, with a brief level-off at 3,000 ft asl.
On final approach to runway 34 at LOWW Vienna International Airport, the aircraft descended from 1,335 ft agl to 107 ft agl in 106 seconds. Stabilisation checks at 1,000 ft and 500 ft above the runway were all met: gear down, landing flap, sink rate, glideslope, centreline, speed, and wings level. The final flap position was 8 at 1,567 ft agl, with an approach speed of 151 kt.
Landing occurred on runway 34, whose length is 3,595 m. The threshold height of 62 ft agl was above target and the threshold speed of 144 kt was slightly above target. The flare was described as perfect; the aircraft floated before touchdown. Touchdown was 522 m beyond the touchdown zone, at a speed of 129 kt and a rate of -117 fpm. The touchdown point was 5.9 m off the centreline but no bounce occurred. Total landing distance was 1,899 m, 53 % of the runway, and rollout alignment was very good.
Local weather at the airport was 8 °C, wind 6 kt from 340°, with no cross-wind and a 5 kt head-wind. After landing, the aircraft taxied to parking in 10 minutes, covering 1 nm. The entire flight covered 529 nm in 106 minutes and used 4,416 kg of fuel.
