What went well

Rollout controlled — 46 % of the runway used
Rotated at 108 kt — on the 109 kt rotation target
Airborne in 1,095 m — 57 % of the runway

What held you back

Arrival Landing — GPWS warning; Threshold speed was well above target at 127 kt at 0 %, Touched down 57 m short of the threshold, so it was never crossed in the air at 0 %, −3.52 points
Firm touchdown — 1,027 fpm with one bounce, −2.07 points across the landing and the touchdown
  • Arrival Touchdown · sink rate 1,027 fpm−1.33
  • Arrival Landing · flare: the descent was not taken out−0.30
  • Arrival Touchdown · bounced once−0.27
  • Arrival Touchdown · 2.12 G at contact−0.17
Arrival Rollout — Runway alignment max 19.78 m right at 41 %, −1.76 points

Next time

Departure

Lower the nose and add power to raise climb speed to 178 kt.

What happened: Climb speed was 155 kt against a target of 178 kt, running 23 kt slow through the climb.

Watch for: Airspeed indicator against the climb target of 178 kt.

See Departure Climb 3

Arrival

Reduce power earlier on final so the speed settles to 115 kt well before the threshold, rather than still decelerating over it.

What happened: The approach was fast through the stabilisation gate, and the aircraft then crossed the threshold at 127 kt against the 115 kt target. Carrying that much extra energy over the numbers usually carries the touchdown point short, as it did here by 400 m.

Watch for: Airspeed indicator: 115 kt at the threshold

See Arrival ApproachArrival LandingArrival Touchdown

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.

Speed and pitch

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

Rotated at 108 kt, on the 109 kt target, and lifted off at 126 kt 4.7 s later, the nose coming up at 1.5° a second. Climb 3 averaged 155 kt, 23 kt under its 178 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 862 ft.

Reached 35 ft with 476 m of runway left; gear up at 76 ft, inside the 400 ft that gets full marks; then climbing at 2,130 fpm on average to 862 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.

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.

Gear down
Landing flap
Sink rate630 fpm
On glideslope3.6°
On speed+35 kt

At the 500 ft gate: speed more than 17 kt above the approach speed of 115 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: fast all the way, gear up until 2.0 nm, banked until 1.4 nm, right of the centreline until 0.4 nm, high from 1.4 nm and sinking too fast from 0.3 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 KPDK 03R

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 3.7 nm, where the final began, to 1.4 nm, then high to the threshold (up to 180 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, 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.

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.

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 flare81.99

The aircraft touched down before the threshold. Everything the flare is measured against - the profile, the crossing height, the aim point - is referenced to a threshold this landing never reached, so read the numbers below as what happened short of the runway, not on it. Landing short is the fault to fix before anything about the hold-off is worth judging.

The crosswind

No crosswind: nothing to correct for. Touched down straight, 4° of bank.

Wind 270° at 1 kt · 0 kt tail · 0 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.

Side view — the last 1,524 m of the approach.

Began the flare at 42 ft, 130 m before the threshold; crossed the threshold at 49 ft, close to the 50 ft target. Touched down 57 m before the threshold.

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.
