Next time

Departure

Keep the helicopter level until it is climbing with speed, then turn.

What happened: The steepest bank while accelerating away was 31°, against 15° for full marks.

Watch for: Attitude indicator: level until established in the climb.

See Departure Transition

Arrival

Line up with the landing spot earlier, so the last part of the approach needs only gentle turns.

What happened: The steepest bank on the approach was 46°, against 20° for full marks.

Watch for: Bank angle: within 20° on the approach.

See Arrival Approach

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.

Flight narrative

The flight began with a hover that was held for 14 seconds, averaging 8 ft above the spot and moving 158 ft over the ground.

The aircraft then accelerated from 13 kt to 60 kt, climbing to 306 ft above the spot in 24 seconds.

Level flight was maintained at 4 400 ft asl for 1 minute, covering 2 nm while the aircraft was overhead Yosemite Valley.

A climb followed from 4 077 ft asl to 4 605 ft asl in 1 minute, covering less than 1 nm, still overhead Yosemite Valley.

The approach started at 442 ft above the landing spot with a speed of 94 kt. The aircraft slowed to 7 kt in 42 seconds, covering less than 1 nm.

Before touchdown, the aircraft hovered for 3 seconds, averaging 15 ft above the spot and moving 22 ft over the ground.

Touchdown occurred with a vertical speed of 92 fpm and a forward speed of 1 kt over the ground.

The total flight covered 3 nm, lasted 4 minutes, and used 9 kg of fuel.
