What held you back

Arrival Landing — Flare profile at 89 %, −0.20 points
Departure Roll — Runway alignment max 22.2 ft right at 87 %, −0.18 points
Arrival Final 1 — Approach angle 3.8 ° at 87 %, −0.10 points

Next time

Departure

Make small rudder corrections against a point at the far end to hold the centreline.

What happened: During the ground roll you drifted 22 ft off the runway centreline.

Watch for: Watch runway alignment against the centreline, correcting with small rudder inputs.

See Departure Roll

Arrive slow and the sink rate at the threshold is already above schedule, the flare is short because there is no energy to extend it, and the touchdown is hard in a way that feels exactly like a late flare. Diagnosing a slow arrival as a late flare is the catastrophic misread: you respond by flaring earlier, which bleeds more speed, which makes the next one worse. The tiebreaker is threshold speed against VRef, not feel. Never diagnose a flare without it.

Plan view the roll down the 11,866 ft runway.

Rolled from the start of the runway, drifted right of the centreline, 21 ft at the widest, and lifted off 21 ft right, in 10 kn of crosswind from the right. Airborne 40 % 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 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 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.

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 figure at liftoff is the pitch then. 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.

When the approach was stable

Every check met from 3.5 to 0.4 nm, then not again: left 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.

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, 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.

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.

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.

Side view — the last 5,000 ft of the approach.

Crossed the threshold at 58 ft, close to the 50 ft target. Touched down 1,296 ft in, 296 ft past the ideal 1,000 ft.

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 5,000 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.

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.

Touched down 8 ft left of the centreline, and stayed about there down the rollout, 11 ft left at the widest. 6 kt across from the right, which takes about 3° of crab to hold the centreline at 137 kt. Touched down with 2° of it still on, wings level.

How to read this

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.

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.

Flight narrative

The flight began with a taxiing period from the parking to the runway, which took 9 minutes and covered a distance of 2 nautical miles. The aircraft, a Boeing 737-800, then departed from runway 27R at Hartsfield Jackson Atlanta International Airport (KATL). The takeoff distance was 4,844 feet, which accounted for 41% of the runway. The liftoff speed was 154 knots.

The local weather conditions at the time of departure were characterized by a temperature of 47°F and a wind speed of 11 knots from a direction of 347°. The crosswind component was 11 knots, while the headwind component was 2 knots. As the aircraft took off, it began its enroute climb, which started overhead KATL. The climb took the aircraft from an altitude of 1,991 feet above sea level to 36,813 feet above sea level, an increase of 34,822 feet, in 19 minutes and covering a distance of 105 nautical miles.

Following the enroute climb, the aircraft entered a level cruise phase, which started 3 miles northeast of Northlake, South Carolina. This phase lasted for 63 minutes and covered a distance of 541 nautical miles. The enroute descent phase began overhead New Dorp Beach, New York, and took the aircraft from an altitude of 37,023 feet above sea level to 1,301 feet above sea level, a decrease of 35,722 feet, in 33 minutes and covering a distance of 180 nautical miles.

The final approach to runway 27 at Logan International Airport (KBOS) was made from the east, with the aircraft heading 256.0° at an altitude of 1,265 feet above ground level and 4 nautical miles from the runway. The landing was made on runway 27, which had a length of 6,979 feet. The threshold height was slightly above the target, and the threshold speed was also slightly above the target at 144 knots.

The touchdown distance was good at 1,303 feet, but the touchdown speed was a little fast at 137 knots. The touchdown rate was firm at -335 feet per minute. The runway touchdown position was slightly misaligned by 11 feet from the centerline. The local weather conditions at the time of landing were characterized by a temperature of 37°F and a wind speed of 8 knots from a direction of 303°. The crosswind component was 6 knots, while the headwind component was 5 knots.

The total landing distance was 4,203 feet, which accounted for 60% of the runway. The runway rollout alignment was perfect. The taxiing period from the runway to the parking took 4 minutes and covered a distance of less than 1 nautical mile. The total flight distance was 835 nautical miles, and the flight duration was 130 minutes. The aircraft used 10,090 pounds of fuel during the flight.
