Speed and pitch

From brake release to the end of the climb, against time, then the takeoff point by point.

Lifted off at 105 kt with 0.2° 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 shaded stretch is Climb 3, the part of the climb scored on holding the climb speed.

Side view from the start of the roll to the end of Climb 3 at 552 ft.

Reached 35 ft with 236 m of runway left; then climbing at 1,140 fpm on average to 552 ft.

How to read this

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.

Plan view the roll down the 1,267 m runway.

Rolled from the start of the runway, drifted left of the centreline, 10 m at the widest, and lifted off 4.6 m left. Airborne 60 % 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 approach to PADU 13

The final from 4 nm.

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

Inside the glideslope band from 2.3 nm, where the final began, to the threshold, never more than 270 ft above the slope.

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.

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 391 m left of the centreline at 2.3 nm, then inside it from 1.7 to 1.4 nm, then drifted 130 m right between 1.4 and 0.8 nm, then 91 m left of it from 0.8 nm to the threshold.

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

3 kt across from the right, which takes about 2° of crab to hold the centreline at 73 kt. Touched down with the nose 3° into wind, 3° of bank.

Wind 239° at 4 kt · 1 kt tail · 3 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.

The stop

From 74 kt at touchdown to taxi speed (30 kt) in 20 s, an average deceleration of 0.12 g.

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.

Side view — the last 1,196 m of the approach.

Crossed the threshold at 2 ft, 48 ft below the 50 ft target. Touched down 24 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 1,196 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 grew from 120 fpm at 2 ft to 190 fpm at touchdown. The pitch barely changed.

How to read this

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 4.7 m left of the centreline, and steered back to 2.2 m right by the end of the rollout.

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.

Flight narrative

The flight began with a taxiing period from the parking area to the runway, which took approximately 3 minutes and covered less than 1 nautical mile. The aircraft, a DHC-6, then departed from runway 26 at PACD Cold Bay Airport in Cold Bay, Alaska. The takeoff distance was 780 meters, which accounted for 62% of the runway length. The liftoff speed was 105 knots.

As the aircraft climbed out of Cold Bay, it encountered local weather conditions of 22°C temperature and a wind speed of 0 knots at 90 degrees. The enroute climb started overhead the airport, where the aircraft ascended from 670 feet above sea level to 1,721 feet, an increase of 1,051 feet in just 1 minute, covering a distance of 2 nautical miles.

The enroute level cruise began 1 mile southwest of Z87 Blinn Lake Seaplane Base in Cold Bay, lasting 15 minutes and covering 37 nautical miles. The aircraft then climbed again, this time from 3,357 feet to 5,128 feet, an increase of 1,770 feet in 4 minutes, covering 12 nautical miles. The level cruise continued 21 miles west of KFP False Pass, lasting 15 minutes and covering 38 nautical miles.

As the aircraft approached its destination, it began its descent from 5,992 feet to 3,934 feet, a decrease of 2,058 feet in 4 minutes, covering 11 nautical miles. The level cruise resumed 14 miles southwest of PACS Cape Sarichef Airport, lasting 4 minutes and covering 9 nautical miles. The aircraft then climbed again from 4,113 feet to 4,934 feet, an increase of 821 feet in 2 minutes, covering 5 nautical miles.

The enroute level cruise continued 12 miles north of PAUT Akutan Airport, lasting 11 minutes and covering 19 nautical miles. The aircraft then began its descent from 6,095 feet to 2,162 feet, a decrease of 3,933 feet in 7 minutes, covering 17 nautical miles. The level cruise resumed 12 miles northeast of Dutch Harbor, lasting 6 minutes and covering 12 nautical miles.

The final approach to runway 13 at PADU Tom Madsen (Dutch Harbor) Airport was made from the northwest, heading 136.0 degrees at 2 nautical miles and 851 feet above ground level. The landing was successful, with a touchdown distance of 22 meters and a touchdown speed of 73 knots, which was slightly fast. The touchdown rate was good at -186 feet per minute, and the runway touchdown position was slightly misaligned by 5.5 meters from the centerline.

The local weather conditions at the time of landing were 24°C temperature and a wind speed of 4 knots at 238 degrees, with a crosswind of 4 knots and a tailwind of 1 knot. The total landing distance was 556 meters, which accounted for 46% of the runway length. The runway rollout alignment was very good. The total flight distance was 165 nautical miles, taking 78 minutes, and the aircraft used 332 kilograms of fuel.
