Flight Score
Arrival
Begin the flare with progressive back pressure and keep it coming until the sink is arrested, rather than flying it on flat.
What happened: The nose was barely raised in the flare and little of the sink was taken out, flying the aircraft onto the runway. This pattern usually carries through to a firm touchdown with a noticeable sink rate.
Watch for: Vertical speed indicator: a smoothly reducing sink through the normal flare band, not a steady rate into the runway.
Ground control varies with speed, full authority at walking pace, progressively reducing as groundspeed rises. The aircraft becomes twitchy at any speed, every small pedal input swings the nose, which can encourage large-amplitude leg inputs that no real aircraft would accept.

From brake release to the end of the climb, against time, then the takeoff point by point.
Rotated at 144 kt, 6 kt above the 138 kt target, and lifted off at 149 kt 1.6 s later, the nose coming up at 3.0° a second. Climb 3 held close to its 154 kt target, at 151 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 944 ft.
Reached 35 ft with 928 m of runway left; gear up at 148 ft, inside the 400 ft that gets full marks; then climbing at 2,820 fpm on average to 944 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 2,188 m runway.
Rolled from the start of the runway, never more than 1.4 m off the centreline. 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.
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 40 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 52× larger than distances along the final.
Inside the 1° band all the way from 4 nm, never more than 6 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 33 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 +4 kt and +5 kt on the approach speed of 133 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 held the target profile well. The aircraft was flown onto the runway - pitch changed 2.0° and the descent was barely arrested. Touchdown was 162 m past the threshold. Start the flare with progressive back pressure rather than one pull, and keep it coming.
Little crosswind (1 kt): nothing to correct for. Touched down straight, wings level.
Wind 029° at 5 kt · 5 kt tail · 1 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 136 kt at touchdown to taxi speed (30 kt) in 31 s, an average deceleration of 0.18 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 1,524 m of the approach.
Began the flare at 16 ft, 14 m before the threshold; crossed the threshold at 13 ft, 37 ft below the 50 ft target. Touched down 162 m in, 143 m short of 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 went from 620 fpm at the flare to 310 fpm at touchdown. The nose came up 0.9° 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 1,524 m of the 2,923 m runway, to the same scale as the side view.
Touched down on the centreline and drifted to 13 m right on the rollout, back to 2.7 m right by the end.
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 162 m touchdown sits inside the full-score zone. The 306 fpm arrival was firm.
The rest of the report
The Airbus A220-300 departed Logan International Airport (KBOS) on runway 22R. The take-off roll used 994 m, which was 45 % of the runway, and rotation occurred at 144 kt. Local weather was 10 °C with a 5 kt wind from 210°, giving a 1 kt crosswind and a 5 kt headwind.
Initial climb to 1,000 ft agl lasted 18 seconds, averaging 2,514 fpm and reaching 149 kt at the top of the climb. The aircraft then climbed from 1,033 ft asl to 29,935 ft asl in 17 minutes, covering 93 nm and passing overhead MA17 Avco/Lowell Heliport (Lowell). Level cruise was held at 30,000 ft asl for 10 minutes, covering 69 nm, beginning about 1 mile east of Sutton.
Descent began from 29,926 ft asl and continued to 1,441 ft asl in 23 minutes, covering 109 nm. The descent started 2 miles south-west of VT01 Teal Farm Airport (Huntington) and included a brief level-off at 3,000 ft asl. The final approach to runway 24L at Montreal-Pierre Elliott Trudeau International Airport (CYUL) descended from 1,375 ft agl to 54 ft agl in 105 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 landing gear was down and the final flap position 4 was selected at 2,413 ft agl while the aircraft was at 166 kt.
Landing on runway 24L (runway length 2,923 m) was performed with a good threshold height and a threshold speed of 137 kt. The flare was described as great, with little round-out. Touchdown occurred at 134 kt, a little fast, and the touchdown rate was firm at minus 307 fpm. Touchdown distance was good at 162 m and alignment was perfect. No bounce occurred. Total landing distance was 1,327 m, 45 % of the runway. Runway rollout alignment was slightly off centreline by 12.5 m.
Local weather at CYUL was 4 °C with a 5 kt wind from 030°, giving a 1 kt crosswind and a 5 kt tailwind. After landing, the aircraft taxied to parking in 7 minutes, covering 1 nm. The entire flight covered 280 nm in 68 minutes and used 2,421 kg of fuel.
