Departure
Lower the nose and add power to raise climb speed to 202 kt.
What happened: Climb speed was 166 kt against a target of 202 kt, running 36 kt slow through the climb.
Watch for: Airspeed indicator against the climb target of 202 kt.
Arrival
Fly the aircraft onto the runway at the aim point instead of holding it off and letting it float further down the runway.
What happened: This landing touched down well beyond the target point on the runway, with nothing else in the approach or flare accounting for it.
Watch for: Aim point markings: touchdown at the target point on the runway.
Between four hundred and a thousand feet you're heavy, close to the ground and still carrying flap, and speed is the margin holding all three apart. Slow here doesn't feel like anything — the aeroplane climbs, the nose is up, nothing complains — right up until a turn, a gust or a bank tightens the wing's job and the margin is already gone. The fix is rarely "fly faster", it's lowering the nose a degree and letting the speed build before the next thing you do. Pitch buys altitude, speed buys options, and at this height options are the scarcer of the two.

From brake release to the end of the climb, against time, then the takeoff point by point.
Rotated at 156 kt, on the 156 kt target, and lifted off at 160 kt 1.6 s later, the nose coming up at 1.6° a second. Climb 3 averaged 166 kt, 36 kt under its 202 kt target.
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.
The takeoff, point by point
Side view from the start of the roll to the end of Climb 3 at 850 ft.
Reached 35 ft with 5,271 ft of runway left; gear up at 90 ft, inside the 400 ft that gets full marks; then climbing at 2,500 fpm on average to 850 ft.
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 13,492 ft runway.
Rolled from 260 ft in, never more than 3 ft off the centreline. Airborne 52 % of the way down the runway, before the 75 % line.
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.
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 the threshold.
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 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 190 ft above the slope.
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 10× larger than distances along the final.
Inside the 1° band all the way from 4 nm, never more than 130 ft off the centreline.
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 33 kt fast at the 1,000 ft gate, closing to 20 at 500 ft and 10 at the threshold.
Inside the speed band all the way, between +2 kt and +7 kt on the approach speed of 130 kt.
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.
Over the threshold
Touchdown
The flare held the target profile well. The flare began at 6 ft agl above the runway, lower than this aircraft wants. Touchdown was 2,380 ft past the threshold. Begin raising the nose earlier - a late flare leaves no time to arrest the sink.
Little crosswind (1 kt): nothing to correct for. Touched down straight, wings level.
Wind 269° at 3 kt · 3 kt head · 1 kt across
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.
From 130 kt at touchdown to taxi speed (30 kt) in 31 s, an average deceleration of 0.17 g.
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 5,668 ft of the approach.
Crossed the threshold at 44 ft, close to the 50 ft target; began the flare late, at 6 ft. Touched down 2,380 ft in, 1,380 ft past the ideal 1,000 ft.
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 5,668 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.
The sink went from 300 fpm at the flare to 40 fpm at touchdown. The nose came up 0.7° 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.
Plan view — the first 5,668 ft of the 14,122 ft runway, to the same scale as the side view.
Touched down 9 ft right of the centreline, and stayed within 10 ft of it down the rollout.
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.
Touched down 2,380 ft past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The Airbus A350-1000 taxied from its parking position to runway 06 at HKJK Jomo Kenyatta International Airport, covering roughly 1 nm in a period of 6 minutes.
During the departure roll on runway 06, the aircraft accelerated to a liftoff speed of 161 kt and left the ground after traveling 7,065 ft, which represented 52 % of the available runway. Ambient conditions were a temperature of 83 °F with a wind of 4 kt from 144°, providing a cross-wind component of 4 kt and no head-wind.
Climb commenced about 1 mile north-east of HKJK, with the airplane ascending from 6,231 ft asl to 40,918 ft asl-a gain of 34,687 ft-over 23 minutes while covering 159 nm.
The first level-cruise segment began 20 miles east of HKGT Garba Tula Airport and persisted for 222 minutes, during which the flight covered 1,793 nm at cruise altitude.
Descent was initiated 28 miles south-east of OMAK Al Ain Airport, with the aircraft descending from 41,000 ft asl to 2,000 ft asl, a loss of 39,001 ft, in 17 minutes while traversing 106 nm.
A brief second cruise phase started 9 miles south-east of OMSH Sharjah Airport, lasting 4 minutes and covering 14 nm before the final approach.
The final approach to runway 30L at OMDB Dubai International Airport was flown from the south-east on a heading of 302.0°, with the aircraft at 4 nm and 1,449 ft agl when established on the approach path.
Landing on runway 30L, which is 14,122 ft long, was achieved with a threshold speed of 133 kt (slightly above target). Touchdown occurred 1,003 ft beyond the touchdown zone at a speed of 127 kt; the vertical speed at touchdown was minus 42 fpm and alignment was perfect. Local weather at the time was 100 °F with a wind of 3 kt from 270°, giving a cross-wind component of 2 kt and a head-wind component of 3 kt. The total landing roll measured 5,391 ft, representing 38 % of the runway length, and rollout alignment remained perfect.
After exiting the runway, the aircraft taxied to its parking area in less than 1 nm of movement, a maneuver that took 3 minutes.
In summary, the flight covered a total of 2,080 nm, required 277 minutes of airborne time, and consumed 50,493 lb of fuel.
