See Arrival Final 4

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 112 kt with 8.1° 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.

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 1,732 m runway.

Rolled from 23 m in, drifted right of the centreline, 1.8 m at the widest, and lifted off 1.6 m left. Airborne 45 % 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 LIEA 20

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 85 m 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 98 m for every nautical mile out, crossing the threshold at about 15 m. 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 16× larger than distances along the final.

Inside the 1° band all the way from 4 nm, never more than 22 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 32 kt fast at the 305 m gate, closing to 18 at 152 m and 10 at the threshold.

Inside the speed band from 4 nm to 2.4 nm, then fast to the threshold (up to +29 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

6 kt across from the left, which takes about 3° of crab to hold the centreline at 102 kt. Touched down with the nose 4° into wind, wings level.

Wind 110° at 7 kt · 1 kt tail · 6 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 103 kt at touchdown to taxi speed (30 kt) in 41 s, an average deceleration of 0.09 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 12 m, close to the 15 m target. Touched down 370 m in, 65 m past 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: 24 m top to bottom, against 1,524 m across. The dashed line is the ideal, 15 m 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 3.5 m/s at 12 m to 1.4 m/s at touchdown. The nose came up 2.5° 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 −3 is 3 m a second 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 a taxiing period from the parking to the runway, which took 5 minutes and covered less than 1 nautical mile. The aircraft, an ATR 42, then departed from runway 21 at LSZS Samedan Airport. The takeoff distance was 755 meters, which accounted for 44% of the runway. The liftoff speed was 113 knots.

The local weather conditions at the time of departure were characterized by a temperature of 16 degrees Celsius and a wind speed of 13 knots from a direction of 200 degrees. This resulted in a crosswind of 2 knots and a headwind of 13 knots. The aircraft then began its enroute climb, starting overhead Celerina in the Kanton Graubunden region of Switzerland. The climb took 12 minutes and covered 13 nautical miles, with the aircraft ascending from an altitude of 2,021 meters above sea level to 6,433 meters.

Following the enroute climb, the aircraft entered a level cruise phase, which started 1 mile west of Zernez in the Kanton Graubunden region of Switzerland. This phase lasted for 74 minutes and covered a distance of 300 nautical miles. The aircraft then began its enroute descent, starting 1 mile north of Coti-Chiavari in the Corse region of France. The descent took 12 minutes and covered 54 nautical miles, with the aircraft descending from an altitude of 6,400 meters to 1,034 meters.

The aircraft then entered another level cruise phase, which started 5 miles northeast of Porto Torres in the Sardegna region of Italy. This phase lasted for only 2 minutes and covered a distance of 6 nautical miles. The aircraft then began its final descent, starting overhead Porto Torres. The descent took 3 minutes and covered 8 nautical miles, with the aircraft descending from an altitude of 969 meters to 492 meters.

The final approach to runway 20 at LIEA Alghero-Fertilia Airport was made from the northeast, with the aircraft heading 204.0 degrees at a distance of 4 nautical miles and an altitude of 466.6 meters above ground level. The landing was made on runway 20, which had a length of 3,007 meters. The threshold height was good, and the threshold speed was well above the target speed of 111 knots.

The touchdown distance was good at 371 meters, but the touchdown speed of 102 knots was a little fast. The touchdown rate was fair at -1.4 meters per second, and the runway touchdown alignment was very good. The local weather conditions at the time of landing were characterized by a temperature of 25 degrees Celsius and a wind speed of 7 knots from a direction of 109 degrees. This resulted in a crosswind of 7 knots and a tailwind of 1 knot.

The total landing distance was 1,100 meters, which accounted for 37% of the runway. The runway rollout alignment was slightly misaligned by 14.5 meters from the centerline. The taxiing period from the runway to the parking took 3 minutes and covered less than 1 nautical mile. The total flight distance was 388 nautical miles, and the flight duration was 116 minutes. The aircraft used 1,039 kilograms of fuel during the flight.
