What went well

Rollout controlled — 29 % of the runway used
Held the centreline on the roll — 3.7 ft off at liftoff

What held you back

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 %, −5.50 points
Departure Roll — Takeoff distance 1,801 ft at 0 %, Strobe Lights at 0 %, −4.11 points
Arrival Approach — stall warning; 300 ft gate 57 %, −3.57 points

Next time

Departure

Hold the nose until reaching 85 kt before rotating.

What happened: Rotation began at 55 kt, 30 kt before the 85 kt target.

Watch for: Airspeed indicator approaching 85 kt.

See Departure Roll

Arrival

Add power on short final to hold speed at 68 kt, correcting the slow threshold speed before it carries through to the flare.

What happened: Threshold speed was slow at 44 kt against 68 kt, and touchdown followed short of the aim point at 31 ft. Crossing the threshold slow like this usually carries the touchdown short.

Watch for: Airspeed indicator against 68 kt on short final.

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.

Flare 36.14The 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 stabilisation gates

One stabilised approach gate: seven 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.

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.

Landing Summary

The final approach to runway 06 at VNLK Lukla Airport was flown from the south-west on a heading of 60.0° at 1 NM distance and -400 ft AGL, with ambient temperature 56 °F, wind 2 kt from 112°, a 1 kt cross-wind component and a 1 kt head-wind component.

Touchdown occurred before the runway threshold.

Touchdown speed was 40 kt and was described as good; the vertical speed was 471 fpm and was noted as perfect. Runway touchdown alignment was very good and the total landing distance measured 333 ft, representing 19 % of the runway length.

During rollout the aircraft was slightly off the centreline, deviating 26 ft to the side.

To improve future performance, aim to touch down at the standard aim point approximately 300 m (1 000 ft) beyond the threshold and maintain a centred track through the rollout to keep alignment within a few feet of the centreline.
