Next time

Departure

Raise the gear lever promptly once a positive climb is confirmed, before reaching the target retraction height.

What happened: Gear retraction was delayed, with the gear not coming up until 818 ft agl.

Watch for: Landing gear: up by the normal retraction gate

See Departure Climb 3

Arrival

Add power at the gate to bring speed up to 141 kt and hold it there.

What happened: The approach was flown too slow, crossing the gate at 136 kt against a target of 141 kt, 5.4 kt under.

Watch for: Airspeed indicator: 141 kt at the gate

See Arrival Approach

Make sure that you retract the landing gear once you have a positive rate of climb and there is no usable runway left to land back on.

Speed and pitch

From brake release to the end of the climb, against time, then the takeoff point by point.

Rotated at 145 kt, 12 kt below the 157 kt target, and lifted off at 154 kt 3.5 s later, the nose coming up at 2.3° a second. Climb 3 averaged 158 kt, 16 kt under its 174 kt target.

How to read this

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.

Side view from the start of the roll to the end of Climb 3 at 927 ft.

Reached 35 ft with 2,116 m of runway left; gear up at 818 ft, 418 ft past the 400 ft that gets full marks; then climbing at 2,520 fpm on average to 927 ft.

How to read this

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 3,542 m runway.

Rolled from the start of the runway, drifted left of the centreline, 2.4 m at the widest, and lifted off 2.5 m left. Airborne 33 % of the way down the runway, before the 75 % line.

How to read this

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.

The stabilisation gates

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.

At the 1,000 ft gate: speed more than 5 kt below the approach speed of 141 kt.

When the approach was stable

Every check met from 3.1 nm, about 990 ft above the runway, to the threshold, after the 1,000 ft gate and before the 500 ft gate. The last to settle was the speed.

How to read this

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 approach to TJSJ 10

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 70 ft below the slope.

How to read this

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.

How to read this

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 3.5 nm, then slow to 3.1 nm (up to −7 kt), then inside the band to the threshold.

How to read this

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.

The crosswind

8 kt across from the right, which takes about 3° of crab to hold the centreline at 138 kt. Touched down with 3° of it still on, wings level.

Wind 149° at 10 kt · 5 kt head · 8 kt across

How to read this

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.

The stop

From 136 kt at touchdown to taxi speed (30 kt) in 28 s, an average deceleration of 0.20 g.

How to read this

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.

How to read this

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 640 fpm at the flare to 130 fpm at touchdown. The nose came up 0.8° 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.

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.

Final approach to runway 10 at TJSJ Luis Munoz Marín International Airport descended from 1,286 ft agl to 65 ft agl in 99 seconds. Stabilisation checks at 1,000 ft and 500 ft above the runway were met for gear down, landing flap, sink rate, glideslope, centreline and wings level; the speed check was not met at one gate. Configuration was landing gear down at 2,353 ft agl at 178 kt and final flap position 5 at 2,339 ft agl at 178 kt.

Landing on runway 10 was on a good threshold height. Threshold speed was 143 kt. The flare was described as perfect. Touchdown occurred at 138 kt, 461 m down the runway, with a smooth rate of minus 126 fpm and very good alignment. No bounce was observed. Total landing distance was 1,309 m, representing 54 % of the runway, and rollout alignment was very good. Local weather at landing was temperature 32 °C, wind 12 kt from 150°, giving a 10 kt crosswind and a 6 kt headwind.

After landing, the aircraft taxied to parking in 1 minute, covering less than 1 nm.

The flight covered a total of 1,425 nm in 214 minutes and used 8,378 kg of fuel.
