Top opportunity

Shorten the long landing

Arrival Touchdown

Ground effect becomes significant below about one wingspan of height. A Cessna 172, with a 36 ft span, enters ground effect at flare height - the float it feels in the hold-off is ground effect arriving on cue. An A320, with a span around 117 ft, has been in ground effect since before the threshold and there is no sudden cushion to feel, only a gradual reduction in induced drag that lengthens any float you allow.

Threshold speed was not the cause here - hold the aim point on the approach and let the aircraft settle rather than holding it off, and the touchdown comes back to the numbers.

During the departure roll on runway 22L, the aircraft accelerated to a liftoff speed of 157 kt and left the ground after traveling 1,378 m, which represented 50 % of the runway length; local weather reported a temperature of 23 °C, wind 4 kt from 210°, a 1 kt crosswind and a 3 kt headwind.

Climb commenced overhead MA17 Avco/Lowell Heliport, rising from 962 ft asl to 38,831 ft asl, an altitude gain of 37,869 ft achieved in 24 minutes while covering 181 nm.

Level cruise began approximately 100 miles south-west of CLE4 Lower East Pubnico Airport and continued for 360 minutes, during which the aircraft flew 3,000 nm.

Descent started 3 miles north-east of Val-de-Meuse, descending from 39,000 ft asl to 2,699 ft asl, a loss of 36,301 ft in 26 minutes and traversing 154 nm.

The final approach to runway 14 at LSZH Zürich Airport was flown from the north-west on a heading of 137.0° at 4 nm and 1,290 ft agl; local conditions were 18 °C, wind 5 kt from 100°, a 3 kt crosswind and a 4 kt headwind.

Landing on runway 14, which is 3,138 m long, occurred with a threshold height of 60 ft agl above target and a threshold speed of 140 kt above target; touchdown was recorded 847 m beyond the touchdown zone at a speed of 134 kt, a vertical rate of minus 78 fpm, and a lateral deviation of 7.1 m from the centreline.

The runway rollout covered a total landing distance of 2,129 m, representing 68 % of the runway, and alignment during rollout was described as very good.

After exiting the runway, the aircraft taxied to the parking area in 2 minutes, covering less than 1 nm.

In total, the flight covered 3,343 nm, required 421 minutes of elapsed time, and consumed 38,187 kg of fuel.

Landing on runway 14 at LSZH Zürich Airport in the Airbus A350-900
Landing Score 92.55 %
Landing Summary

The Airbus A350-900 executed the final approach to runway 14 at LSZH Zürich Airport from the north-west, maintaining a heading of 137.0° at 4 nm and 1,290 ft above ground level. Local weather was 18 °C with a wind of 5 kt from 100°, including a 3 kt cross-wind component and a 4 kt head-wind component.

At the threshold the aircraft was 60 ft above ground level, which was above target, and the threshold speed was well above target at 140 kt. The flare proceeded from this condition.

Touchdown occurred 847 m beyond the designated touchdown zone, with a speed of 134 kt that was a little fast, and a touchdown rate of minus 78 fpm that was excellent. The touchdown point was slightly misaligned by 7.1 m from the centreline.

The total landing distance measured 2,129 m, representing 68 % of the 3,138 m runway, and the runway rollout alignment was very good.

With a final score of 87.2% the landing was solid; reduce the approach and touchdown speeds to bring the threshold speed and touchdown speed within target values, which will also allow an earlier touchdown within the zone. Align the touchdown point closer to the centreline to minimise the 7.1 m offset.
