See Arrival Final 3

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.

Speed and pitch

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

Lifted off at 96 kt with 6.3° 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 706 ft.

Reached 35 ft with 515 m of runway left; then climbing at 950 fpm on average to 706 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 1,523 m runway.

Rolled from 79 m in, drifted 6.6 m right of the centreline and was back on it to lift off. Airborne 51 % 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 approach to KSEA 16C

The final from 4 nm.

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

Inside the glideslope band from 3.8 nm, where the final began, to the threshold, never more than 490 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 4× larger than distances along the final.

Inside the 1° band all the way from 3.8 nm, never more than 89 m off the centreline.

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.

Speed against the approach speed. The green band runs from 5 kt slow to 78 kt fast at the 1,000 ft gate, closing to 48 at 500 ft and 10 at the threshold.

Inside the speed band from 3.8 nm, where the final began, to 3.1 nm, then slow to the threshold (up to −22 kt).

How to read this

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.

The crosswind

Little crosswind (1 kt): nothing to correct for. Touched down straight, 6° of bank.

Wind 350° at 8 kt · 7 kt tail · 1 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 87 kt at touchdown to taxi speed (30 kt) in 11 s, an average deceleration of 0.29 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 1,524 m of the approach.

Crossed the threshold at 43 ft, close to the 50 ft target. Touched down 169 m in, 136 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 1,524 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.

Sink and pitch — through the flare, lined up with the side view.

The sink went from 880 fpm at 42 ft to 340 fpm at 0 ft, then back up to 600 fpm at touchdown. The nose came up 5.8° on the way down.

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.

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 the aircraft, a Beechcraft Duke, taxiing from the parking area to the runway at CZBB Boundary Bay Airport. This process took 11 minutes and covered a distance of 1 nautical mile. The departure roll took place on runway 25, and the takeoff distance was 707 meters, which accounted for 46% of the runway. The liftoff speed was 96 knots.

As the aircraft took to the skies, it encountered local weather conditions with a temperature of 14 degrees Celsius and a wind speed of 7 knots at 284 degrees. The crosswind was 2 knots, and the headwind was 7 knots. The enroute climb started 1 mile south east of Ladner, British Columbia, and the aircraft ascended from 741 feet above sea level to 9,180 feet above sea level, an increase of 8,439 feet in 7 minutes, covering a distance of 8 nautical miles.

The enroute level cruise began 5 miles south west of White Rock, British Columbia, and lasted for 16 minutes, covering a distance of 55 nautical miles. The aircraft then started its enroute descent 3 miles north of Freeland, Washington, and descended from 9,425 feet above sea level to 5,027 feet above sea level, a decrease of 4,398 feet in 5 minutes, covering a distance of 18 nautical miles.

The enroute level cruise resumed overhead Woodway, Washington, and lasted for 2 minutes, covering a distance of 5 nautical miles. The enroute descent began 2 miles south of Shoreline, Washington, and the aircraft descended from 5,017 feet above sea level to 1,878 feet above sea level, a decrease of 3,139 feet in 5 minutes, covering a distance of 12 nautical miles.

The final approach to runway 16C at KSEA Seattle–Tacoma International Airport took place from the north, heading 180.0 degrees at 3 nautical miles and 1,426 feet above ground level. The landing on runway 16C was successful, with a runway length of 2,872 meters. The threshold height was good, and the threshold speed was a little below target at 77 knots.

The touchdown distance was good at 166 meters, and the touchdown speed was 74 knots, which was also good. However, the touchdown rate was very hard at -596 feet per minute. The runway touchdown alignment was perfect, and the local weather conditions at the time of landing were a temperature of 12 degrees Celsius and a wind speed of 8 knots at 350 degrees. The crosswind was 1 knot, and the tailwind was 7 knots.

The total landing distance was 427 meters, which accounted for 15% of the runway. The runway rollout alignment was perfect. The taxiing to the parking area from the runway took 2 minutes and covered less than 1 nautical mile. The total flight distance was 104 nautical miles, and the flight duration was 43 minutes. The aircraft used 167 kilograms of fuel during the flight.
