Flight Score
Departure
Correct the drift with small rudder corrections against a point at the far end of the runway, holding the centreline through the roll.
What happened: The takeoff roll drifted 19 m off the centreline, and the aircraft held a bank angle of 5.2° through the first climb segment; drifting off centreline on the roll usually carries into a wandering heading through the second climb.
Watch for: Heading indicator: runway heading held steady through the climb.
Arrival
Add power to hold 88 kt over the threshold so you arrive with enough energy to let the aircraft settle smoothly onto the runway.
What happened: The aircraft crossed the threshold at 79 kt, 9 kt below the 88 kt target, then the sink was arrested at 21 ft and held there instead of continuing down. Holding off high like this usually leaves the touchdown to chance, and firm touchdowns often follow.
Watch for: Airspeed indicator: 88 kt at the threshold
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.

2 landings
The flight is kept as it was recorded: it ends when the engine is shut down, so a landing with the rotors turning is a stop along the way, not a new flight.
| # | Where | Into flight | Touchdown | Ground speed | Sideways | On the ground |
|---|---|---|---|---|---|---|
| 1 | LFLJ · Courchevel Altiport | 4:38 | 1774 ft/min | 8.4 kt | 0.0 kt | 0:30 |
| 2 | LFLJ · Courchevel Altiport | 5:38 | 0 ft/min | 0.0 kt | 0.0 kt | End of flight |
From brake release to the end of the climb, against time, then the takeoff point by point.
Rotated at 74 kt, 14 kt below the 88 kt target, and lifted off at 78 kt 1.2 s later, the nose coming up at 4.7° a second. Climb 3 averaged 96 kt, 31 kt under its 127 kt target.
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 dashed green line is the speed to rotate at for this aircraft at its weight, and the green dot is where the nose started to come up. The figures at liftoff are the pitch then and how fast the nose came up, in degrees a second. The shaded stretch is Climb 3, the part of the climb scored on holding the climb speed.
The takeoff, point by point
Side view from the start of the roll to the end of Climb 3 at 997 ft. The distance scale changes past the runway end.
Reached 35 ft at the runway end; gear up at 48 ft, inside the 400 ft that gets full marks; then climbing at 1,230 fpm on average to 997 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. The gear-up ring is coloured by its mark. The shaded stretch is Climb 3, scored on its average speed against the target.
Plan view the roll down the 796 m runway.
Rolled from 59 m in, drifted left of the centreline, 16 m at the widest, and lifted off 16 m left, in 5 kn of crosswind from the left. Airborne 67 % 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.
One stabilised approach gate: five checks where the approach path is 300 ft above the runway. The 1,000 ft gate was not assessed, because the approach did not join final that far out. These checks are the approach's score.
At the 300 ft gate: glideslope more than 2° off the runway's 3° and speed more than 5 kt below the approach speed of 88 kt.
Still turning onto final at the lower gate, so the centreline and wings level are not asked there - the aeroplane was not lined up yet, and was banked because it was turning. The other checks are marked as usual.
When the approach was stable
Never every check met at once: low all the way, left of the centreline until 0.2 nm, slow from 0.6 nm to the threshold.
Each line is one of the gate checks, run along the whole final rather than only at the gates: green where it would have passed, amber where it would not. The glideslope, centreline and speed lines use the bands in the charts beside this card. The sink rate is allowed what the glideslope needs at your ground speed plus 600 fpm, the wings 10° of bank, and the gear and flap are read from when you moved the levers. The bottom line is green where every check held at once, ignoring blips shorter than 0.2 nm, and the sentence above it says from where it held to the threshold. A ring is a stabilisation gate, where the checks in the table were taken.
The final from 4 nm, with the stabilisation gates on it.
Profile height against the 3° glideslope, with its 2° band in green.
Low from 1.3 nm, where the final began, to the threshold (up to 460 ft under).
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. A ring is a stabilisation gate: green when every check there passed, amber with the failed checks named beside it.
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 339 m right of the centreline at 1.3 nm, then drifted 45 m left between 0.7 and 0.2 nm, then inside the band from 0.2 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.
Speed against the approach speed. The green band runs from 5 kt slow to 44 kt fast at the 1,000 ft gate, closing to 26 at 500 ft and 10 at the threshold.
Inside the speed band from 1.3 nm, where the final began, to 0.6 nm, then slow to the threshold (up to −15 kt).
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.
Over the threshold
Touchdown
The flare strayed well off the target profile. The flare took the sink out 21 ft agl above the runway and the aircraft flew down from there. Touchdown was 24 m past the threshold. Let it come lower before checking the descent - holding off high uses runway and leaves the touchdown to chance.
6 kt across from the right, which takes about 5° of crab to hold the centreline at 73 kt. Touched down straight - the crab taken out before the wheels touched, wings level.
Wind 310° at 7 kt · 1 kt head · 6 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.
From 80 kt at touchdown to taxi speed (30 kt) in 11 s, an average deceleration of 0.24 g.
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 520 m of the approach.
Began the flare at 21 ft, 31 m before the threshold. Touched down 24 m in, 281 m short of the ideal 305 m.
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 520 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 1,230 fpm at the flare to 790 fpm at touchdown. The nose came up 6.5° 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 −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 full 520 m runway, to the same scale as the side view.
Touched down 2.2 m left of the centreline, and stayed within 2.5 m of it down 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.
The 24 m touchdown sits inside the full-score zone. The 2.05 G arrival is the firm side of smooth.
The rest of the report
Departing from Albertville General Pierre Delachenal Airfield, the PC-12 began its journey with a taxiing period of 7 minutes, covering a short distance of less than 1 nautical mile to reach the runway. The departure roll commenced on runway 05, with the aircraft taking off in 563 meters, utilizing 81% of the available runway length. The liftoff speed was achieved at 79 knots, as the aircraft lifted off into the local weather conditions, characterized by a temperature of 22°C and a wind speed of 8 knots from 283°.
As the aircraft transitioned into the enroute phase, it began its climb from 1,918 feet above sea level, reaching an altitude of 11,350 feet in just 5 minutes, covering a distance of 12 nautical miles. The climb rate was impressive, with an increase of 9,432 feet in a short period. The aircraft then initiated its descent, starting 1 mile northwest of Aigueblanche, and descended from 11,349 feet to 6,176 feet in 4 minutes, covering 13 nautical miles. The final approach to Courchevel Altiport's runway 22 was conducted from the northeast, with the aircraft aligning perfectly with the runway at 1 nautical mile and -300 feet above ground level.
The touchdown was executed smoothly, with the aircraft touching down before the threshold at a speed of 73 knots. The touchdown rate was impressive, at 226 feet per minute, and the runway touchdown alignment was spot on. The total landing distance was 237 meters, utilizing 44% of the available runway length. The runway rollout alignment was also perfect, indicating a well-executed landing. The total flight distance was 28 nautical miles, completed in 15 minutes, with the aircraft consuming 56 kilograms of fuel.
