Departure
Reduce climb power to bring speed back to 170 kt and hold it there.
What happened: Climb speed was 72 kt fast at 242 kt during the climb.
Watch for: Airspeed indicator: 170 kt in the climb
Arrival
Begin raising the nose earlier, by 11 ft, so the flare has time to arrest the sink before touchdown.
What happened: The flare began late at 1.1 ft, 10 ft below the normal band, and a late flare like this usually leaves too little time to arrest the sink before touchdown.
Watch for: Watch radio altitude and start the flare in the normal band, around 11 ft.
High on final, the pilot dives to the aim point, converting altitude directly into airspeed, and arrives on-glideslope but 15 knots fast. The vertical profile looks fine; the speed trace does not. It is one of the reasons the stabilised-approach concept - configured, on speed, on path by a gate, commonly 1,000 ft in IMC and 500 ft in VMC - checks speed and path together, and why the tolerances airlines use are asymmetric, typically allowing more on the fast side than the slow, because slow kills faster than fast.

From brake release to the end of the climb, against time, then the takeoff point by point.
Rotated at 138 kt, 4 kt below the 142 kt target, and lifted off at 150 kt 2.3 s later, the nose coming up at 2.7° a second. Climb 3 averaged 242 kt, 72 kt over its 170 kt target.
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 2,325 m of runway left; gear up at 69 ft, inside the 400 ft that gets full marks; then climbing at 1,180 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 3,586 m runway.
Rolled from the start of the runway, never more than 0.4 m off the centreline. Airborne 20 % 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.
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 1.0 nm, then not again: fast from 1.0 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 30 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 8× larger than distances along the final.
Inside the 1° band all the way from 4 nm, never more than 49 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 35 kt fast at the 1,000 ft gate, closing to 21 at 500 ft and 10 at the threshold.
Inside the speed band from 4 nm to 1.0 nm, then fast to the threshold (up to +18 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 strayed well off the target profile. Crossing the threshold 11 kt above target, the flare began at 1 ft agl above the runway, lower than this aircraft wants. Touchdown was 357 m past the threshold. Begin raising the nose earlier - a late flare leaves no time to arrest the sink.
No crosswind: nothing to correct for. Touched down straight, 2° of bank.
Wind 269° at 1 kt · 1 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.
Side view — the last 1,524 m of the approach.
Crossed the threshold at 54 ft, close to the 50 ft target; began the flare late, at 1 ft. Touched down 357 m in, 52 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 1,524 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 stayed between 650 fpm and 660 fpm from the flare to the runway. The pitch barely changed.
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 1,524 m of the 2,644 m runway, to the same scale as the side view.
Touched down 2.1 m left of the centreline, and stayed within 2.8 m 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 357 m touchdown sits inside the full-score zone. The 1.76 G arrival is the firm side of smooth.
The rest of the report
The Airbus A320neo departed from runway 27L at LFPG Charles de Gaulle International Airport. The take-off roll was 739 m, representing 21 % of the runway. Rotation occurred at 138 kt. Local weather was 17 °C with wind 1 kt from 270°, crosswind 0 kt and headwind 1 kt.
Initial climb to 1,000 ft agl took 40 seconds, averaging 1,092 fpm and reaching 248 kt at the top of the segment. The aircraft then climbed from 1,267 ft asl to 26,777 ft asl in 7 minutes, covering 43 nm while passing overhead Goussainville.
Cruise was level at 25,000 ft asl for 99 minutes, covering 716 nm, beginning over Prunay-sur-Essonne. Descent began from 27,312 ft asl to 25,050 ft asl in 2 minutes, covering 11 nm, starting overhead Boissy-sous-Saint-Yon.

The aircraft then levelled at 1,800 ft asl for 7 minutes, covering 27 nm, starting 7 miles north-east of Sidi Bou Said.
Final approach to runway 29 at DTTA Tunis Carthage International Airport began with a descent from 1,324 ft agl to 75 ft agl in 89 seconds. Stabilisation checks at 1,000 ft and 500 ft above the runway were met: gear down, landing flap, sink rate, on glideslope, on centreline, on speed, wings level.
Landing was on runway 29, runway length 2,644 m. The threshold height was good and the threshold speed was slightly above target at 152 kt. The flare was described as very good, starting early. Touchdown occurred 357 m down the runway at 146 kt, a little fast, with a heavy rate of -662 fpm. Alignment at touchdown was very good and no bounce occurred. Total landing distance was 956 m, 36 % of the runway, and rollout alignment was perfect.
The flight covered 886 nm in 133 minutes, using 2,702 kg of fuel. Local weather at landing was 15 °C with wind 1 kt from 270°, crosswind 0 kt and headwind 1 kt.
