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.

Lifted off at 58 kt with 0.7° of pitch.

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 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.

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 approach to I98D 09

Profile height against the 3° glideslope, with its 2° band in green.

On the glideslope from 3.3 nm, where the final began, to 2.2 nm, then high to 1.1 nm (up to 980 ft over), then back on it to the threshold.

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, 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.

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.

The crosswind

No crosswind: nothing to correct for. Touched down with the nose 5° left of the track, 6° of bank.

Wind 090° at 4 kt · 4 kt head · 0 kt across

How to read this

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 291 m of the approach.

Crossed the threshold at 10 ft, 40 ft below the 50 ft target. Touched down 23 m in, 281 m short of the ideal 305 m.

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 291 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.

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.

Flight narrative

The flight began with a departure roll from runway 10 at I99D Dewey Moore Airstrip, a small airstrip in Idaho, United States. The DHC-2 Beaver aircraft accelerated down the 101-meter runway, covering 42% of its length, before lifting off into the air at a speed of 59 knots. The local weather conditions at the time of takeoff were characterized by a temperature of 24 degrees Celsius and a gentle wind blowing at 4 knots from a direction of 87 degrees.

As the aircraft climbed away from the airstrip, it began to ascend to a higher altitude, passing over the nearby town of DEW Dewey Moore Big Creek. The climb was steep, with the aircraft rising from an initial altitude of 4,469 feet above sea level to 5,683 feet in just one minute, covering a distance of 2 nautical miles. This impressive climb rate was achieved despite the aircraft's relatively small size and modest engine power.

After reaching the desired altitude, the pilot began the final approach to runway 09 at I98D Vines Airstrip, a nearby airstrip that was the destination of the flight. The approach was made from the west, with the aircraft flying at a heading of 99.0 degrees and descending to an altitude of 1,570 feet above ground level. The pilot then lined up with the runway and began the landing sequence.

The landing itself was smooth, with the aircraft touching down on the runway at a speed of 57 knots. However, the touchdown rate was somewhat heavy, with the aircraft descending at a rate of -758 feet per minute. The runway touchdown position was also slightly misaligned, with the aircraft deviating from the centerline by 7.3 meters. Despite these minor issues, the total landing distance was only 189 meters, which was just 65% of the runway length.

After touching down, the pilot began the rollout, which was also slightly misaligned, with the aircraft deviating from the centerline by 10.2 meters. The total flight distance was a relatively short 3 nautical miles, and the flight used a total of 7 kilograms of fuel. Overall, the flight was a successful one, with the pilot demonstrating good flying skills and a high degree of control over the aircraft.
