Flight Score
Arrival
Start the flare with progressive back pressure and keep it coming until the sink is arrested.
What happened: The aircraft was flown onto the runway: the nose was barely raised and little of the sink was taken out, touching down at 276 fpm.
Watch for: Pitch attitude: rising steadily through the flare until the sink is checked.
See Arrival Landing
There are several things that can go wrong during the flare, carrying too much speed over the threshold, starting the flare at the wrong height and inconsistent flight control inputs, all contribute to a poor flare resulting in a hard touchdown or a float down the runway.

From brake release to the end of the climb, against time, then the takeoff point by point.
Rotated at 141 kt, 4 kt below the 145 kt target, and lifted off at 152 kt 4.6 s later, the nose coming up at 1.7° a second. Climb 3 averaged 166 kt, 13 kt under its 179 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 904 ft.
Reached 35 ft with 4,238 ft of runway left; gear up at 166 ft, inside the 400 ft that gets full marks; then climbing at 2,150 fpm on average to 904 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 10,544 ft runway.
Rolled from the start of the runway, drifted 9 ft right of the centreline and was back on it to lift off. Airborne 48 % 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 30 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, 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 28× larger than distances along the final.
Inside the 1° band all the way from 4 nm, never more than 40 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 36 kt fast at the 1,000 ft gate, closing to 22 at 500 ft and 10 at the threshold.
Inside the speed band all the way, between −0 kt and +2 kt on the approach speed of 144 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 mostly held the target profile. The aircraft was flown onto the runway - pitch changed 0.1° and the descent was barely arrested. Touchdown was 1,201 ft past the threshold. Start the flare with progressive back pressure rather than one pull, and keep it coming.
No crosswind: nothing to correct for. Touched down straight, wings level.
Wind 177° at 5 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 152 kt at touchdown to taxi speed (30 kt) in 24 s, an average deceleration of 0.28 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 5,000 ft of the approach.
Crossed the threshold at 37 ft, 13 ft below the 50 ft target; began the flare at 31 ft. Touched down 1,201 ft in, 201 ft past 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 500 fpm at the flare to 280 fpm at touchdown. 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 5,000 ft of the 12,014 ft runway, to the same scale as the side view.
Touched down on the centreline, and stayed within 5 ft 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 1,201 ft touchdown sits inside the full-score zone. The 1.83 G arrival is the firm side of smooth.
The rest of the report
The Boeing 737-800 departed KSTL on runway 12R. The take-off roll was 5,111 ft, using 48 % of the runway, and rotation occurred at 141 kt. Local weather was 64 °F with a wind 10 kt from 126°, giving a 1 kt crosswind and a 10 kt headwind.
Initial climb to 1,000 ft agl took 22 seconds, averaging 2,147 fpm and reaching 166 kt at the top of the segment. The climb continued from 1,567 ft asl to 35,993 ft asl in 19 minutes, covering 115 nm and passing overhead Kinloch. Level flight was held at 36,000 ft asl for 77 minutes, covering 521 nm, beginning 4 miles north-west of 61MO Carl Ensor Airport Grainville.
Descent began at 35,718 ft asl and proceeded to 6,647 ft asl in 23 minutes, covering 108 nm, starting 10 miles south of 17V Haxtun Muni Haxtun. The final approach to runway 17R at KDEN descended from 1,313 ft agl to 52 ft agl in 93 seconds. Stabilisation checks at 1,000 ft and 500 ft above the runway were met for gear down, landing flap, sink rate, glideslope, centreline, speed and wings level. Configuration was landing gear down at 2,645 ft agl at 182 kt and final flap position 7 at 2,046 ft agl at 179 kt.
Landing on runway 17R (runway length 12,014 ft) had a good threshold height and a threshold speed of 146 kt. The flare was described as perfect. Touchdown occurred 1,327 ft down the runway at 144 kt, a little fast, with a fair touchdown rate of minus 204 fpm and perfect runway-touchdown alignment. No bounce occurred. Total landing distance was 4,332 ft, 36 % of the runway, and rollout alignment was perfect. Local weather was 47 °F with wind 2 kt from 073°, a 2 kt crosswind and a 1 kt tailwind.
Taxi from the runway to parking took 10 minutes and covered 2 nm. The overall flight covered 755 nm in 143 minutes and used 12,046 lb of fuel.
