Next time

Departure

Use coordinated aileron input to level the wings and hold bank angle close to wings-level during the climb.

What happened: During the initial climb, your average bank angle drifted to 5.4°.

Watch for: Attitude indicator, bank angle near wings-level

See Departure Climb 1

Arrival

Hold the aim point and wait for the proper flare height before you start rotating; let the runway come up to you rather than anticipating it.

What happened: The flare began early, well above the normal flare band, and touchdown followed at 1,060 m past the threshold, 603 m beyond the 457 m target. Starting the flare early like this usually carries the touchdown long.

Watch for: Radio altimeter against the normal flare band, then touchdown distance against 457 m.

See Arrival LandingArrival Touchdown

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 165 kt, 10 kt above the 155 kt target, and lifted off at 175 kt 3.3 s later, the nose coming up at 1.4° a second.

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.

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.

When the approach was stable

Every check met from 4 nm to 1.1 nm, then not again: fast from 0.7 nm and right of the centreline 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.

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.

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.

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 flare91.84

The flare held the target profile well. The flare began at 63 ft agl above the runway, higher than this aircraft wants. Touchdown was 1,060 m past the threshold. Hold the aim point and let the runway come to you rather than anticipating the flare.

The crosswind

No crosswind: nothing to correct for. Touched down with the nose 4° left of the track, wings level.

Wind 058° at 4 kt · 4 kt head · 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 146 kt at touchdown to taxi speed (30 kt) in 26 s, an average deceleration of 0.24 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 1,890 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.

Cruise continued between 33,000 ft asl and 35,000 ft asl for 259 minutes, covering 2,405 nm, beginning 18 miles south-west of Yarmouth. A further climb from 34,999 ft asl to 36,955 ft asl took 3 minutes and covered 27 nm, starting at latitude 39.4261019 longitude -12.3047685. Cruise between 37,000 ft asl and 41,000 ft asl lasted 432 minutes, covering 3,580 nm, starting at latitude 39.1964652 longitude -11.7646482.

Descent began from 40,975 ft asl to 6,628 ft asl in 17 minutes, covering 108 nm, starting 7 miles south-east of Sotik. The final approach to runway 06 at HKJK Jomo Kenyatta International Airport descended from 1,354 ft agl to 98 ft agl in 95 seconds. Stabilisation checks at 1,000 ft and 500 ft above the runway were met for gear down, landing flap, glideslope, centreline, speed and wings level; the sink-rate check was not met at one gate. Configuration on final was landing gear down at 1,870 ft agl at 178 kt and final flap position 4 at 1,841 ft agl at 177 kt.

Landing on runway 06, which is 4,112 m long, occurred with a good threshold height. Threshold speed was slightly above target at 146 kt. The flare was described as great, starting early. Touchdown was 645 m beyond the touchdown zone, at a speed of 136 kt, a little fast, with a smooth rate of -136 fpm. Touchdown position was misaligned by 10.2 m from the centreline. Local weather was 22 °C, wind 4 kt from 058°, giving a 4 kt headwind and no crosswind. No bounce occurred. Total landing distance was 1,814 m, 44 % of the runway, and rollout alignment was misaligned by 22.9 m from the centreline.

After landing, the aircraft taxied to the parking area in 4 minutes, covering 1 nm. The total flight covered 6,353 nm in 752 minutes and used 81,119 kg of fuel.
