What held you back

Arrival Approach — GPWS warning; 500 ft gate 80 %, −1.67 points
Arrival Touchdown — Touchdown rate was -280 fpm at 76 %, −0.40 points

Next time

Arrival

Be established on the glideslope before the gate, with small corrections made early rather than a large one late.

What happened: The approach was off the glideslope at the stabilisation gate.

Watch for: Glideslope indication at the gate

See Arrival Approach

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.

89 % The flare mostly held the target profile. Crossing the threshold 16 kt above target, the flare took all the sink out 16 ft agl above the runway and the aircraft then dropped the rest of the way, 228 fpm of sink coming back. Touchdown was 382 m past the threshold. Hold the attitude and let it settle rather than pushing - that excess speed is what turns a normal flare into a balloon, so the fix is on the approach, not in the flare.

Speed and pitch

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

Rotated at 121 kt, on the 123 kt target, and lifted off at 131 kt 2.2 s later, the nose coming up at 5.1° a second. Climb 3 averaged 173 kt, 10 kt under its 183 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.

Reached 35 ft with 1,559 m of runway left; gear up at 5 ft, inside the 400 ft that gets full marks; then climbing at 2,600 fpm on average to 867 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 2,782 m runway.

Rolled from 195 m in, never more than 0.3 m off the centreline. Airborne 35 % 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

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.

Landing flap
Sink rate1,160 fpm

At the 500 ft gate: glideslope more than 1° off the runway's 3°.

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: banked until 0.9 nm, high until 0.4 nm, left of the centreline from 1.4 nm and sinking too fast from 0.4 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 VQPR 15

The final from 4 nm, with the stabilisation gates on it.

Profile height against the 3° glideslope, with its 1° band in green.

High from 2.4 nm, where the final began, to 1.7 nm (up to 580 ft over), then back on it to 0.9 nm, then high to 0.4 nm (up to 110 ft over), then back on it to the threshold.

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.

Joined 1,113 m right of the centreline at 2.4 nm, then 162 m left of it from 1.4 nm to the threshold.

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 30 kt fast at the 1,000 ft gate, closing to 18 at 500 ft and 10 at the threshold.

Inside the speed band all the way, between +7 kt and +21 kt on the approach speed of 120 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 crosswind

No crosswind: nothing to correct for. Touched down with the nose 2° left of the track, wings level.

Wind 269° 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.

The stop

From 137 kt at touchdown to taxi speed (30 kt) in 13 s, an average deceleration of 0.43 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.

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.

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.
