Below 10,000 ft you are typically limited to 250 kt indicated (a US rule that much of the world mirrors in some form, though not universally). This forces a deceleration around 10,000 ft whether the profile wants one or not, so plan for it rather than discovering it.

From brake release to the end of the climb, against time, then the takeoff point by point.
Lifted off at 125 kt with 5.9° of pitch.
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 takeoff, point by point
Side view from the start of the roll to 188 ft.
Reached 35 ft with 5,149 ft of runway left; then climbing at 860 fpm on average to 188 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.
Plan view the roll down the 9,200 ft runway.
Rolled from 1,458 ft in, never more than 3 ft off the centreline, in 7 kn of crosswind from the left. Airborne 34 % 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.
The final from 4 nm.
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 210 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.
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 1,570 ft right of the centreline, then inside the band from 2.1 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.
Over the threshold
Touchdown
5 kt across from the left, which takes about 2° of crab to hold the centreline at 122 kt. Touched down with 2° of it still on, wings level.
Wind 300° at 20 kt · 19 kt head · 5 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 5,108 ft of the approach.
Crossed the threshold at 43 ft, close to the 50 ft target. Touched down 1,911 ft in, 911 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 5,108 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 590 fpm at 42 ft to 140 fpm at touchdown. The nose came up 3.7° 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 5,108 ft of the 9,200 ft runway, to the same scale as the side view.
Touched down 15 ft left of the centreline, and steered back to 3 ft left 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 1,911 ft past the threshold — beyond the full-score zone. The 1.42 G arrival bounced 3 times.
The rest of the report
The B-2 Spirit aircraft departed from runway 33L at KBOS Logan International Airport, taking off with a distance of 1,759 feet, which is 19% of the runway length. The aircraft lifted off at a speed of 125 knots. At the time of departure, the local weather conditions were characterized by a temperature of 24°F, with a wind speed of 29 knots coming from a direction of 300°. This resulted in a crosswind of 8 knots and a headwind of 28 knots.
As the aircraft climbed away from the airport, it began its enroute climb, which started overhead KBOS Logan International Airport. The aircraft climbed from an altitude of 223 feet above sea level to 1,057 feet, an increase of 834 feet, in just 3 minutes. During this climb, the aircraft covered a distance of 4 nautical miles.
The final approach to runway 33L was made from the southeast, with the aircraft heading 305.0° at an altitude of 1,029 feet above ground level and a distance of 3 nautical miles from the runway. The landing was executed with a threshold speed that was slightly above the target speed of 140 knots.
The touchdown point was 524 feet beyond the touchdown zone, but the touchdown speed of 122 knots was good, and the touchdown rate was smooth at -135 feet per minute. The runway touchdown position was slightly misaligned by 15 feet from the centerline. The local weather conditions at the time of landing were characterized by a temperature of 22°F, with a wind speed of 20 knots coming from a direction of 299°. This resulted in a crosswind of 5 knots and a headwind of 19 knots.
The total landing distance was 4,821 feet, which is 52% of the runway length. The runway rollout alignment was very good, indicating a smooth and controlled landing. The aircraft then taxied to the parking area from the runway, taking less than 1 minute and covering a distance of less than 1 nautical mile.
The total flight distance was 8 nautical miles, and the flight duration was 6 minutes. The aircraft used a total of 2,280 pounds of fuel during the flight.
