See Arrival Final 3
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.

From brake release to the end of the climb, against time, then the takeoff point by point.
Lifted off at 73 kt with 2.1° of pitch.
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 figure at liftoff is the pitch then. 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 847 ft. The distance scale changes past the runway end.
Reached 35 ft 93 m past the runway end; then climbing at 1,230 fpm on average to 847 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 shaded stretch is Climb 3, scored on its average speed against the target.
Plan view the roll down the 298 m runway.
Rolled from 37 m in, drifted right of the centreline, 3.3 m at the widest, and lifted off 3.3 m right. Airborne 65 % 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.
One stabilised approach gate: seven checks where the approach path is 300 ft above the runway. The 1,000 ft gate was not assessed, because the approach did not join final that far out.
At the 300 ft gate: glideslope more than 2° off the runway's 3°.
When the approach was stable
Never every check met at once: fast until 1.3 nm, banked until 1.3 nm, right of the centreline until 1.1 nm, high until 0.3 nm, sinking too fast from 0.4 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 2° band in green.
On the glideslope from 2.4 nm, where the final began, to 2.1 nm, then high to 0.3 nm (up to 710 ft over), then back on it to the threshold.
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 3× larger than distances along the final.
Joined 1,193 m right of the centreline at 2.4 nm, then inside the band from 1.1 nm to the threshold.
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.
Fast from 2.4 nm, where the final began, to 1.3 nm (up to +43 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
Touchdown
Very good landing flare
12 kt across from the right, which takes about 11° of crab to hold the centreline at 60 kt. Touched down with 7° of it still on, wings level.
Wind 110° at 15 kt · 7 kt head · 12 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 57 kt at touchdown to taxi speed (30 kt) in 14 s, an average deceleration of 0.16 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 1,303 m of the approach.
Crossed the threshold at 41 ft, close to the 50 ft target. Touched down 296 m in, close to 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 1,303 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 570 fpm at 41 ft to 280 fpm at touchdown. The nose came up 4.3° 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 full 1,303 m runway, to the same scale as the side view.
Touched down 3.2 m left of the centreline and drifted to 13 m right on 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 arrow beside the runway is the crosswind, pointing the way the air was moving, so it pushed the aircraft that way.
The 296 m touchdown sits inside the full-score zone. The 1.37 G arrival bounced.
The rest of the report
The flight began with a departure roll from runway 12 at Juancho E. Yrausquin Airport, a small airport located on the island of Saba in the Caribbean Netherlands. The aircraft, a DHC-6, took off with a takeoff distance of 164 meters, which accounted for 55% of the runway. The liftoff speed was 74 knots, and the local weather conditions were characterized by a temperature of 29 degrees Celsius and a wind speed of 11 knots from a direction of 106 degrees.
As the aircraft climbed away from the airport, it encountered a crosswind of 1 knot and a headwind of 11 knots. The enroute climb started 1 mile east of the airport and lasted for 1 minute, during which the aircraft ascended from an altitude of 1,011 feet above sea level to 2,118 feet, an increase of 1,108 feet. The climb covered a distance of 2 nautical miles.
Following the climb, the aircraft entered a level cruise phase, which started 2 miles east of the airport and lasted for 10 minutes. During this phase, the aircraft covered a distance of 14 nautical miles. The cruise phase was followed by a final approach to runway 06 at F.D. Roosevelt Airport, which was located to the southwest of the aircraft's position.
The final approach was made at a heading of 5.0 degrees and at an altitude of 1,284 feet above ground level. The aircraft was 2 nautical miles from the airport when it began its descent. The landing was made on runway 06, which had a length of 1,303 meters. The threshold height was good, and the threshold speed was slightly above the target speed of 75 knots.
The touchdown distance was good at 295 meters, and the touchdown speed was 60 knots, which was within the acceptable range. The touchdown rate was firm at -304 feet per minute. However, the runway touchdown position was slightly misaligned from the centerline by 3.4 meters. The local weather conditions at the time of landing were similar to those at takeoff, with a temperature of 29 degrees Celsius and a wind speed of 11 knots from a direction of 106 degrees.
The crosswind component was 9 knots, and the headwind component was 6 knots. The total landing distance was 568 meters, which accounted for 44% of the runway. The runway rollout alignment was also slightly misaligned from the centerline by 12.9 meters. The total flight distance was 19 nautical miles, and the flight duration was 15 minutes. The aircraft used a total of -131 kilograms of fuel during the flight.
