What held you back

Departure Roll — Takeoff distance 1,801 ft at 0 %, Strobe Lights at 0 %, −4.77 points
Arrival Landing — Threshold speed at 44 kt was well below target, take care not to stall at 0 %, Touched down 31 ft short of the threshold, so it was never crossed in the air at 0 %, −4.32 points

Next time

Departure

Hold the nose down until the speed reaches 85 kt, then rotate.

What happened: You started the rotation at 46 kt, 39 kt before the 85 kt rotation speed.

Watch for: Airspeed indicator: 85 kt at rotation

See Departure Roll

Arrival

Add power on final to keep the approach speed at 70 kt rather than letting it decay before the threshold.

What happened: The aircraft crossed the threshold at 44 kt, 26 kt below the target, and touchdown followed with a firm, high sink rate arrival. Crossing the threshold slow like this usually carries through to a firmer touchdown as the flare runs out of energy.

Watch for: Airspeed indicator: 70 kt at the threshold.

See Arrival LandingArrival Touchdown

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.

Rotated at 46 kt, 39 kt below the 85 kt target, and lifted off at 55 kt 5.8 s later with 7.8° 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 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 figure at liftoff is the pitch then.

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 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: 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.

Landing flap
Sink rate350 fpm
On glideslope1.9°
On speed+1.4 kt

At the 300 ft gate: no landing flap set and glideslope more than 2° off the runway's 3°.

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, right of the centreline until 0.7 nm, no landing flap until 0.4 nm, slow from 0.3 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.

Low from 1.3 nm, where the final began, to the threshold (up to 470 ft under).

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, 1,000 ft 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.

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 flare52.67

The aircraft touched down before the threshold. Everything the flare is measured against - the profile, the crossing height, the aim point - is referenced to a threshold this landing never reached, so read the numbers below as what happened short of the runway, not on it. Landing short is the fault to fix before anything about the hold-off is worth judging.

The crosswind

Little crosswind (1 kt): nothing to correct for. Touched down with the nose 3° right of the track, wings level.

Wind 121° at 2 kt · 1 kt head · 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 46 kt at touchdown to taxi speed (30 kt) in 7 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.

Began the flare late, at 3 ft; crossed the threshold at -61 ft, 111 ft below the 50 ft target. Touched down 31 ft before the threshold.

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 1,776 ft across. The dashed line is the ideal, 50 ft over the threshold and down 1,000 ft 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.

Flight narrative

The Britten-Norman BN2 Islander taxied from the parking area to runway 24 in less than 1 minute, covering less than 1 nm.

The aircraft commenced its departure roll on runway 24 at VNLK Lukla Airport; takeoff distance was 1,801 ft, representing 101 % of the runway. Liftoff speed was 56 kt. Ambient temperature was 56 °F with wind from 119° at 3 kt, a 2 kt crosswind and a 1 kt tailwind.

En-route descent began overhead VNLK Lukla Airport, descending from 8,865 ft asl to 8,724 ft asl-a loss of 141 ft in 1 minute while covering 1 nm.

Level cruise was established 1 mile southwest of VNLK Lukla Airport and lasted 3 minutes, during which the aircraft covered 1 nm.

The final approach to runway 06 at VNLK Lukla Airport was flown from the southwest on a heading of 60.0° at 1 nm and -400 ft agl. Local weather reported temperature 56 °F, wind from 112° at 2 kt, with a 1 kt crosswind and a 1 kt headwind.

Touchdown occurred before the threshold at a speed of 40 kt and a descent rate of 471 fpm. Total landing distance was 333 ft, 19 % of the runway, and rollout alignment was slightly misaligned by 26 ft from the centreline.

The flight covered a total distance of 4 nm, lasted 3 minutes, and used -1 lbs of fuel.
