Departure
Raise the gear lever promptly once a positive climb is confirmed, before reaching the target retraction height.
What happened: Gear retraction was delayed, with the gear not coming up until 6,981 ft agl.
Watch for: Landing gear: up by the normal retraction gate
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.

The roll
Liftoff and climb
Plan view the roll down the 3,520 m runway.
Rolled from 105 m in, drifted 10 m right of the centreline and was back on it to lift off. Airborne 63 % 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.
Side view from the start of the roll to the end of Climb 3 at 1,003 ft.
Reached 35 ft with 1,007 m of runway left; then climbing at 1,650 fpm on average to 1,003 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 dark stretch of the roll is the run with the nose up and the wheels still on, with its length and time under the runway. The shaded stretch is Climb 3, scored on its average speed against the target.
Speed and pitch from brake release to the end of the climb, against time.
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 grey band is the run between the nose coming up and the wheels leaving the runway. The figures at liftoff are the pitch then and how fast the nose came up, in degrees a second. The rotation detail below draws the rotation against the rates for this aircraft and its tail-strike pitch, where the slope reads properly. The grey dashed line across the pitch is the attitude held from 35 ft to the end: a nose held steady is a climb speed that holds, and the airspeed trace sits directly above it to compare. The shaded stretch is Climb 3, the part of the climb scored on holding the climb speed.
Rotation detail the pitch over the seconds from rotation to 35 ft, where the slope reads properly.
The pitch over the seconds from the nose starting to come up to 35 ft, stretched so the slope reads properly. The green dot is where the nose started up, the grey band runs to the wheels leaving, and the figures at liftoff are the pitch then and how fast the nose came up. The two dashed green lines rising from the rotation point are 2 to 3° a second, the rates airliners are rotated at: a trace steeper than both is a faster rotation, one shallower than both a slower one. The red dashed line is 12.1°, the pitch at which this aircraft's tail touches the runway with the wheels still on it, drawn from rotation to liftoff only: once the wheels leave, every foot climbed adds tail clearance.
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 3.5 to 2.6 nm, then not again: left of the centreline from 1.5 nm, slow from 1.3 nm and low from 0.9 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.
On the glideslope from 4 nm to 2.4 nm, then low to 1.6 nm (up to 690 ft under), then back on it to 0.9 nm, then low to 0.4 nm (up to 260 ft under).
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 168 m left of the centreline, then inside it from 3.5 to 1.5 nm, then 236 m left of it from 1.5 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 38 kt fast at the 1,000 ft gate, closing to 23 at 500 ft and 10 at the threshold.
Inside the speed band from 4 nm to 1.3 nm, then slow to 0.4 nm (up to −23 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
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.
Touchdown
Rollout
Taxi in
Side view — the last 1,524 m of the approach.
Began the flare at 15 ft, 1,284 m before the threshold; crossed the threshold at 37 ft, 13 ft below the 50 ft target; ballooned 60 ft from 1 ft. Touched down 786 m before the threshold.
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.
Plan view — the first 1,524 m of the 3,798 m runway, to the same scale as the side view.
9 kt across from the right, which takes about 4° of crab to hold the centreline at 128 kt. Touched down with the nose 6° into wind, 4.7° of bank.
Wind 183° at 12 kt · 7 kt head · 9 kt across
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. 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. The sentence gives the nose against the direction you were actually moving as the wheels touched, and the steepest bank as they touched, the figure the touchdown's Bank tile marks. The rest of it is shown for reading, not marked.
Touched down 786 m short of the threshold. The 2.99 G arrival is the firm side of smooth.
The stop — touchdown to taxi speed.
From 141 kt at touchdown to taxi speed (30 kt) in 35 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.
The rest of the report
The Boeing 747-8 taxied to runway 01 at SKRG Jose Maria Córdova International Airport and commenced the departure roll. The aircraft used a takeoff distance of 2,245 m, representing 64 % of the runway, and lifted off at 166 kt. Ambient conditions were 23 °C with a wind of 2 kt from 045°, including a 1 kt cross-wind and a 1 kt head-wind component.

The first cruise segment started 5 nm south-east of Caparrapi and lasted 5 minutes, during which the aircraft progressed 26 nm at level flight.
Descent commenced 5 nm north of Argelia, descending from 25,650 ft asl to 12,014 ft asl, a loss of 13,636 ft over 7 minutes and a distance of 52 nm.
A second cruise phase originated 3 nm south of El Rosal, persisting for 3 minutes and covering 15 nm.
The next descent started 3 nm north of Facatativa, dropping from 11,978 ft asl to 10,324 ft asl, a decrease of 1,654 ft in 2 minutes across 7 nm.
A further level cruise began 3 nm south-east of El Rosal and lasted 3 minutes, adding 15 nm to the flight path.
The subsequent descent was initiated 3 nm east of Facatativa, reducing altitude from 10,221 ft asl to 9,516 ft asl, a loss of 705 ft in 2 minutes while traveling 6 nm.
Final approach to runway 14R at SKBO El Dorado International Airport was flown from the north-west on a heading of 131.0° at 4 nm and 1,137 ft agl.
A go-around was executed on runway 14R at an altitude of 25 ft agl, indicating the aircraft aborted the initial landing attempt.
A second go-around followed on the same runway at 16 ft agl before a later successful approach and landing.
Touchdown occurred before the threshold of runway 14R at a speed of 128 kt, with a vertical speed of minus 1,310 fpm. The touchdown point was misaligned by 202.0 m from the centreline. Local weather at the time was 16 °C with a wind of 11 kt from 179°, including an 8 kt cross-wind and a 6 kt head-wind component. The total landing distance recorded was 1,316 m, representing 35 % of the runway, and rollout alignment was off by 196.8 m from the centreline.
The aircraft taxied from the runway to parking in 4 minutes, covering less than 1 nm.
In total, the flight covered 159 nm, required 35 minutes, and consumed 5,923 kg of fuel.
