Flight Score
Arrival
Add power on final to keep the approach speed at 116 kt rather than letting it decay before the threshold.
What happened: The aircraft crossed the threshold at 106 kt, 10 kt below the target, and touchdown followed with a firm, high sink rate arrival. Crossing the threshold slow like this usually carries through to a firmer touchdown as the flare runs out of energy.
Watch for: Airspeed indicator: 116 kt at the threshold.
Preparing for a stable approach will give you time to decide on whether to attempt the landing or going around. Too much altitude with a high sink rate will result in carrying too much speed onto the runway. Configuring flaps and the gear late also won't help the speed decay.

The roll
A slow rotation
The nose came up at 133 kt against the 131 kt rotate speed, and rose at 1.6° a second, slower than the 2.1 to 2.9 other Cessna 750 Citation X pilots fly.
The rotation started on speed but the nose came up slowly. Make it one positive, continuous pull at the normal rate for this aircraft, rather than easing the nose up in steps.
Liftoff and climb
Plan view the roll down the 6,495 ft runway.
Rolled from 158 ft in, drifted left of the centreline, 15 ft at the widest, and lifted off 16 ft left. Airborne 46 % 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.
Side view from the start of the roll to the end of Climb 3 at 972 ft. The distance scale changes past the runway end.
Reached 35 ft with 2,621 ft of runway left; gear up at 27 ft, inside the 400 ft that gets full marks; then climbing at 1,670 fpm on average to 972 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 2.1 to 2.9° a second, the middle half of rotation rates flown by other Cessna 750 Citation X pilots over the last 180 days (54 takeoffs). 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 six 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.
At the 1,000 ft gate: speed more than 29 kt above the approach speed of 116 kt.
At the 500 ft gate: speed more than 17 kt above the approach speed of 116 kt.
When the approach was stable
Every check met from 0.5 to 0.3 nm, then not again: low from 0.3 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.
On the glideslope from 4 nm to 0.3 nm, then low to the threshold (up to 50 ft under).
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. 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 20 ft 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 29 kt fast at the 1,000 ft gate, closing to 17 at 500 ft and 10 at the threshold.
Fast from 4 nm to 0.5 nm (up to +111 kt), then inside the band to the threshold.
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
Great landing flare
It lost 4.5 points, mostly for taking only 398 fpm of the sink out.
Touchdown
Rollout
Taxi in
Side view — the last 5,000 ft of the approach.
Began the flare at 41 ft, 813 ft before the threshold; crossed the threshold at 6 ft, 44 ft below the 50 ft target. Touched down 93 ft in, 907 ft short of 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 570 fpm at the flare to 290 fpm at touchdown. The nose came up 2.8° on the way down. Into the flare at 112 kt, 4 kt under the 116 kt approach speed, and 105 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 5,000 ft of the 6,477 ft runway, to the same scale as the side view.
Touched down 8 ft left of the centreline, and stayed about there down the rollout, 10 ft left at the widest.
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 93 ft touchdown sits inside the full-score zone. The arrival was smooth.
The stop — touchdown to taxi speed.
From 102 kt at touchdown to taxi speed (30 kt) in 12 s, an average deceleration of 0.30 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.
