What went well

Touched down at -128 fpm — a soft arrival
Straight touchdown — 9.3 ft off the centreline, no bounce
Rotated at 149 kt — on the 143 kt rotation target

What held you back

Arrival Rollout — Runway alignment max 158.6 ft left at 0 %, −3.00 points
Arrival Landing — bank angle up to 22.9 ° at 45 %, Runway alignment max 96.4 ft right at 58 %, −1.36 points
Arrival Touchdown — bank angle up to 10.1 ° at 0 %, Touchdown distance was 2,818 ft at 56 %, −1.06 points

Next time

Arrival

Track the centreline through touchdown using small rudder corrections against a point at the far end of the runway.

What happened: The aircraft touched down off the centreline at 96 ft, and drifting off centreline at touchdown usually carries through into the rollout, as it did here with alignment reaching 159 ft.

Watch for: Watch runway centreline position, keeping deviation inside the limit through touchdown and rollout.

See Arrival LandingArrival Rollout

Ground effect becomes significant below about one wingspan of height. A Cessna 172, with a 36 ft span, enters ground effect at flare height - the float it feels in the hold-off is ground effect arriving on cue. An A320, with a span around 117 ft, has been in ground effect since before the threshold and there is no sudden cushion to feel, only a gradual reduction in induced drag that lengthens any float you allow.

Speed and pitch

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

Rotated at 149 kt, 6 kt above the 143 kt target, and lifted off at 157 kt 3.2 s later, the nose coming up at 1.8° a second. Climb 3 averaged 167 kt, 12 kt under its 179 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 864 ft.

Reached 35 ft with 4,927 ft of runway left; gear up at 177 ft, inside the 400 ft that gets full marks; then climbing at 2,040 fpm on average to 864 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.

Rolled from 179 ft in, drifted left of the centreline, 21 ft at the widest, and lifted off 17 ft left. Airborne 46 % 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 stabilisation gates

One stabilised approach gate: five checks where the approach path is 500 ft above the runway. The 1,000 ft gate was not assessed, because the approach did not join final that far out. These checks are the approach's score.

On speed+1.9 kt

Still turning onto final at the lower gate, so the centreline and wings level are not asked there - the aeroplane was not lined up yet, and was banked because it was turning. The other checks are marked as usual.

When the approach was stable

Never every check met at once: right of the centreline all the way, banked until 0.9 nm, high from 1.3 nm and fast from 1.0 nm to the threshold.

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 PAJN 08

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 1.3 nm, then high to the threshold (up to 280 ft over).

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, 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 3× larger than distances along the final.

Joined 5,510 ft right of 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 34 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 1.0 nm, then fast to the threshold (up to +20 kt).

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 flare79.87

The flare wandered off the target profile. The flare arrested the sink and then let it come back - 764 fpm of it - so the aircraft dropped the last few feet. Touchdown was 2,818 ft past the threshold. Keep the back pressure coming once the flare is established.

The crosswind

Little crosswind (2 kt): nothing to correct for. Touched down with the nose 3° left of the track, 7° of bank.

Wind 114° at 17 kt · 16 kt head · 2 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 118 kt at touchdown to taxi speed (30 kt) in 18 s, an average deceleration of 0.28 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.

Side view — the last 5,000 ft of the approach.

Crossed the threshold at 65 ft, 15 ft above the 50 ft target; began the flare at 28 ft; ballooned 5 ft from 15 ft. Touched down 2,818 ft in, 1,818 ft past the ideal 1,000 ft.

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 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.

From the flare the descent stopped and turned into a climb of 180 fpm before coming down at 130 fpm to touch. The nose went down 1.3° 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.

Flight narrative

The Boeing 737-800 taxied from the parking area to runway 16L at KSEA for 12 minutes, covering 3 nm, and departed on runway 16L. Takeoff used 5,520 ft of runway (46 % of runway). Rotation occurred at 149 kt. Local weather was 43 °F with wind 4 kt from 012°, a 1 kt crosswind and a 4 kt tailwind.

Initial climb to 1,000 ft agl lasted 23 seconds, averaging 1,817 fpm and reaching 167 kt at the top of the climb. The aircraft then climbed from 1,314 ft asl to 35,885 ft asl in 18 minutes, covering 110 nm, beginning about 1 mile south-west of SeaTac. Cruise was level at 36,000 ft asl for 91 minutes, covering 607 nm, starting 16 miles south of Lake Cowichan. Descent began at 35,332 ft asl and proceeded to 756 ft asl in 23 minutes, covering 113 nm, starting 10 miles east of PAFE Kake Airport, with a brief level-off at 5,000 ft asl.

Final approach to runway 08 at PAJN started from 1,200 ft agl and descended to 92 ft agl in 104 seconds. At 500 ft above the runway the stabilisation checks were met: gear down, landing flap, sink rate, on glideslope, on speed. Configuration on final was gear down at 4,112 ft agl at 198 kt; final flap position 8 was selected at 3,848 ft agl at 167 kt.

Landing was on runway 08 (runway length 8,942 ft). The threshold height at 66 ft agl was above target and the threshold speed was well above target at 148 kt. The flare was described as good; the aircraft dropped onto the runway at the end of the flare. Touchdown occurred 1,524 ft beyond the touchdown zone, at 136 kt, a little fast, with a touchdown rate of minus 199 fpm. The touchdown point was 15 ft off the centreline, with no bounce. Total landing distance was 4,647 ft (52 % of runway). Runway rollout alignment was excessively misaligned by 159 ft from the centreline.

Local weather at PAJN was 40 °F with wind 17 kt from 114°, a 3 kt crosswind and a 16 kt headwind. After landing, the aircraft taxied to the parking area for 3 minutes, covering less than 1 nm.

The flight covered a total of 839 nm in 149 minutes and used 12,885 lb of fuel.
