Departure

Ease the yoke smoothly to hold a steady one g through the ground roll instead of letting it sag to 0.4 g.

What happened: During the ground roll the g force averaged 0.4 g, well below the smooth steady load expected while tracking the runway.

Watch for: Watch the g meter and hold it steady near one g through the roll.

See Departure Roll

Arrival

Reduce power earlier on final to bleed speed back to 68 kt before crossing the threshold.

What happened: You crossed the threshold at 108 kt, 40 kt above the 68 kt target.

Watch for: Airspeed, targeting 68 kt at the threshold.

See Arrival Landing

Every knot above Vref is stored kinetic energy, and energy stored at the threshold must be dissipated in ground effect before the aeroplane will stop flying. Because kinetic energy scales with the square of speed, the excess you must dissipate grows fast. At a 45-knot approach, five knots hot is over a tenth more speed and roughly a quarter more energy to get rid of in ground effect. This is why the fix is never in the flare. It was decided three miles earlier, on final, at the airspeed indicator.

Speed and pitch

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

Lifted off at 69 kt with 3.4° 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.

Rolled from 508 m in, drifted left of the centreline, 5 m at the widest, and lifted off 5 m left, in 6 kn of crosswind from the left. Airborne 22 % 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 stabilisation gates

One stabilised approach gate: seven checks where the approach path is 500 ft above the runway. The 1,000 ft gate was not assessed, because the approach did not join final that far out.

Seven checks, one gate500 ft
Gear down
Landing flap
Sink rate
On glideslope
On centreline
On speed
Wings level

At the 500 ft gate: gear still up, no landing flap set, sink rate more than 600 fpm beyond what the glideslope needed, glideslope more than 2° off the runway's 3°, wings more than 10° from level and speed more than 21 kt above the approach speed of 70 kt.

When the approach was stable

Never every check met at once: sinking too fast all the way, high all the way, fast all the way, banked until 1.3 nm, no landing flap until 1.0 nm, gear up until 0.4 nm, left of the centreline from 1.3 nm to the threshold.

How to read this

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.

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

High from 2.6 nm, where the final began, to the threshold (up to 1,890 ft over).

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. A ring is a stabilisation gate: green when every check there passed, amber with the failed checks named beside it.

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.

Fast from 2.6 nm, where the final began, to the threshold (up to +71 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

13 kt across from the right, which takes about 12° of crab to hold the centreline at 65 kt. Touched down with 12° of it still on, 4° of bank.

Wind 010° at 14 kt · 2 kt head · 13 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 70 kt at touchdown to taxi speed (30 kt) in 14 s, an average deceleration of 0.16 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 77 ft, 27 ft above the 50 ft target. Touched down 812 m in, 508 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: 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 710 fpm at 81 ft to 50 fpm at 51 ft, then back up to 630 fpm at touchdown. The nose came up 5.6° 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.

Touched down 20 m left of the centreline, and steered back to 9.7 m left 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

Departing runway 05 at LFBD Bordeaux-Mérignac Airport, the Piper PA-24-250 Comanche began its takeoff roll, accelerating to liftoff speed of 70 kt in a distance of 698 m, which represented 23% of the available runway. The aircraft lifted off with a headwind component of 15 kt, which contributed to a relatively short takeoff distance.

As the aircraft climbed away from Bordeaux-Mérignac, it transitioned into a steady enroute climb, reaching an altitude of 3,555 ft asl in just 5 minutes. This climb phase was characterized by a significant increase in altitude, with a gain of 2,773 ft. Following the climb, the aircraft entered a level cruise phase, maintaining an altitude of 3,555 ft asl for 7 minutes while covering a distance of 17 nm. The descent phase that followed was initiated 1 mile west of Cestas, with the aircraft losing 1,800 ft in altitude in just 3 minutes. This descent phase was completed in preparation for the final approach to runway 29 at LFBD Bordeaux-Mérignac Airport.

The final approach was initiated from the east, with the aircraft heading 276.0° at 2 nm and 1,899 ft agl. However, the landing was not without issues, as the touchdown point was 302 m beyond the touchdown zone, and the touchdown speed of 65 kt was slightly higher than desired. Furthermore, the touchdown rate was very hard at -537 fpm, and the runway touchdown position was significantly misaligned by 20.1 m from the centreline. The total landing distance of 1,058 m represented 44% of the available runway, and the runway rollout alignment was also misaligned by 20.2 m from the centreline. Despite these challenges, the aircraft completed the flight, covering a total distance of 37 nm and consuming 13 kg of fuel in the process.
