Departure
Make small rudder corrections against a point at the far end to hold the centreline.
What happened: During the ground roll you drifted 35 m off the runway centreline.
Watch for: Watch runway alignment against the centreline, correcting with small rudder inputs.
See Departure Roll
Arrival
Be established on the glideslope by the gate, and take the power back earlier on final so the height and the speed come back together. Do not push down for the height: that only adds speed.
What happened: The approach was off the glideslope at the gate, and the aircraft then crossed the threshold at 124 ft agl, 74 ft agl above the 50 ft agl target, and at 170 kt, 43 kt over the 127 kt threshold speed. High and fast together is energy the runway has to absorb, and this touchdown came 736 m beyond the aim point.
Watch for: Glideslope indication at the gate, then airspeed: 127 kt on short final
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.

From brake release to the end of the climb, against time, then the takeoff point by point.
Rotated at 176 kt, 22 kt above the 154 kt target, and lifted off at 182 kt 1.2 s later, the nose coming up at 2.4° a second. Climb 3 averaged 203 kt, 29 kt over its 174 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 874 ft.
Reached 35 ft with 2,204 m of runway left; gear up at 215 ft, inside the 400 ft that gets full marks; then climbing at 2,970 fpm on average to 874 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 4,012 m runway.
Rolled from 101 m in, drifted 35 m left of the centreline and was back on it to lift off. Airborne 37 % 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.
One stabilised approach gate: seven 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.
At the 500 ft gate: gear still up, sink rate more than 600 fpm beyond what the glideslope needed, glideslope more than 1° off the runway's 3°, centreline more than 1° off, wings more than 10° from level and speed more than 19 kt above the approach speed of 127 kt.
When the approach was stable
Never every check met at once: high all the way, fast all the way, gear up until 1.4 nm, banked until 0.6 nm, sinking too fast from 0.6 nm and left of the centreline from 0.5 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.
High from 4 nm to the threshold (up to 1,180 ft over).
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.
Inside the 1° band from 4 nm to 2.0 nm, then drifted 127 m right between 2.0 and 0.9 nm, then back inside it from 0.9 to 0.5 nm, then 19 m left of it from 0.5 nm to the threshold.
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 32 kt fast at the 1,000 ft gate, closing to 19 at 500 ft and 10 at the threshold.
Fast from 4 nm to the threshold (up to +86 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 mostly held the target profile. Pitch was -1.7° at touchdown, at or below this aircraft's ground attitude, so the nosewheel met the runway with the main wheels or before them. Touchdown was 1,193 m past the threshold. Keep raising the nose through the flare so the main wheels touch first.
Little crosswind (2 kt): nothing to correct for. Touched down with the nose 11° left of the track, wings level.
Wind 279° at 3 kt · 1 kt head · 2 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.
Side view — the last 2,295 m of the approach.
Crossed the threshold at 123 ft, 73 ft above the 50 ft target; began the flare at 14 ft. Touched down 1,193 m in, 888 m past the ideal 305 m.
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 2,295 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.
Sink and pitch — through the flare, lined up with the side view.
The sink went from 440 fpm at the flare to 260 fpm at touchdown. The pitch barely changed.
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 2,295 m of the 4,344 m runway, to the same scale as the side view.
Touched down 68 m right of the centreline, and steered back to 28 m right by the end of 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 1,193 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The Airbus A321neo taxied from the parking area to runway 34C at OEJN King Abdulaziz International Airport in 6 minutes, covering 1 nm.
Take-off was performed on runway 34C with a take-off distance of 1,481 m (37 % of the runway). Rotation occurred at 176 kt. The local weather at departure was temperature 33 °C, wind 3 kt from 048°, giving a 3 kt crosswind and a 1 kt headwind.
Initial climb to 1,000 ft agl took 13 seconds, averaging 2,683 fpm and reaching 203 kt at the top of the segment. The climb continued from 1,000 ft asl to 12,670 ft asl in 6 minutes, covering 30 nm, with a brief level-off at 6,000 ft asl while overhead OEJN.
The aircraft then levelled at 13,000 ft asl for 5 minutes, covering 29 nm, starting 31 miles north of OEJN. A subsequent climb from 13,003 ft asl to 25,027 ft asl lasted 5 minutes and covered 29 nm, beginning 18 miles south-east of OERB Rabigh Airport.
Cruise was maintained at 25,000 ft asl for 12 minutes, covering 69 nm, starting 32 miles east of Rabigh. Descent from 25,037 ft asl to 4,035 ft asl took 19 minutes and covered 94 nm, beginning 21 miles south of Medina.
Final approach to runway 35 at OEMA Prince Mohammad Bin Abdulaziz Airport began with a descent from 2,076 ft agl to 171 ft agl in 50 seconds. Stabilisation checks at 500 ft above the runway were met for landing flap; they were not met for gear down, sink rate, glideslope, centreline, speed, and wings level. The landing gear was lowered at 808 ft agl at 229 kt. The final flap position 9 was selected at 562 ft agl at 209 kt.
Landing occurred on runway 35, whose length is 4,344 m. The threshold height at 124 ft agl was excessively over target and the threshold speed was excessively high at 170 kt. The flare was described as very good; the aircraft touched down flat with the nosewheel first. Touchdown was 780 m beyond the touchdown zone, at a speed of 146 kt, which was fast, and a rate of -256 fpm, which was fair. The touchdown point was misaligned by 68.2 m from the centreline. No bounce occurred.
Total landing distance was 2,185 m, representing 50 % of the runway. Runway rollout alignment was misaligned by 82.5 m from the centreline. Local weather at landing was temperature 31 °C, wind 3 kt from 279°, giving a 2 kt crosswind and a 1 kt headwind.
After landing, the aircraft taxied to the parking area in 4 minutes, covering 1 nm. The total flight covered 259 nm, lasted 58 minutes, and used 1,910 kg of fuel.
