What held you back

Arrival Touchdown — Forward at touchdown 20.0 kt at 0 %, Touched down at 547 fpm at 13 %, −3.15 points
Arrival Approach — bank angle up to 47.9 ° at 0 %, Fastest descent 2,569 fpm at 0 %, −1.95 points
Arrival Touchdown — Touched down at 550 fpm at 13 %, −1.75 points

Next time

Arrival

Keep forward airspeed until the descent is nearly stopped: reduce the rate of descent first, then let the speed come off.

What happened: For 63% of the approach the helicopter was slow and descending fast together, and it met the ground at 444 fpm. A slow, fast descent is hard to stop with collective, and a firm touchdown usually follows.

Watch for: Airspeed and vertical speed together: never low airspeed with a fast descent.

See Arrival ApproachArrival Touchdown

As you slow through about 20 knots near the end, add collective to offset the loss of translational lift, together with the matching pedal. Keep some forward speed until you're close to the ground.

Every landing in this flight

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.

Flight narrative

**Flight 1 - Bell 407**

The aircraft lifted into a hover and held it for 9 seconds, averaging 8 ft above the spot and moving 18 ft over the ground. It then accelerated from 3 kt to 61 kt, reaching 144 ft above the spot in 14 seconds. The climb phase rose from 1,672 ft asl to 3,579 ft asl in 1 minute while covering 2 nm, starting overhead Sarnen. Level flight was maintained at approximately 3,300 ft asl for 1 minute, covering 3 nm, also starting overhead Sarnen. Descent began from 3,188 ft asl to 1,977 ft asl in 4 minutes over 7 nm, starting overhead Alpnach, with a brief level-off at 2,200 ft asl.

The approach started 495 ft above the landing spot at 44 kt and decelerated to 20 kt in 73 seconds, covering less than 1 nm. Touchdown occurred at 547 fpm with 20 kt over the ground. After landing the aircraft accelerated from 0 kt to 18 kt, climbing to 347 ft above the spot in 15 seconds.

**Flight 2 - Bell 407**

Following a hover held for 4 seconds at an average of 8 ft above the spot and moving 21 ft over the ground, the aircraft accelerated from 6 kt to 26 kt, reaching 326 ft above the spot in 16 seconds. It then climbed from 1,795 ft asl to 2,623 ft asl in 1 minute, covering 3 nm, starting overhead Ennetburgen. Level flight was held at about 2,700 ft asl for 4 minutes, covering 9 nm, starting overhead Beckenried. Descent proceeded from 2,375 ft asl to 1,959 ft asl in 1 minute over 1 nm, starting overhead Flueelen.

The approach began 500 ft above the landing spot at 51 kt and slowed to 7 kt in 48 seconds, covering less than 1 nm. Touchdown was recorded at 550 fpm with 6 kt over the ground.

**Flight 3 - Bell 407**

The aircraft performed a series of five short climbs, descents and level legs between 1,800 ft asl and 3,400 ft asl over 10 minutes, covering 21 nm, from overhead Seedorf to 1 mile north-west of Walchwil. Level flight continued at 2,600 ft asl for 4 minutes, covering 8 nm, starting overhead Cham.

The final approach started 492 ft above the landing spot at 19 kt and decelerated to 5 kt in 47 seconds, covering less than 1 nm. The aircraft hovered before landing for 17 seconds, averaging 21 ft above the spot and moving 266 ft over the ground. Touchdown occurred at 444 fpm with 3 kt over the ground.

The total flight distance for the three legs was 55 nm, the total time was 33 minutes, and fuel consumption was 121 kg.
