What went well

Touched down at 168 fpm — a soft arrival
No sideways movement at touchdown
Approach kept its airspeed on the way down — no fast, slow descent

What held you back

Arrival Hover — Moved over the ground at 11.6 kt on average at 34 %, Height held within 11 ft at 43 %, −4.80 points
Departure Transition — Nose down by up to 20 ° at 73 %, −0.90 points
Enroute Level — bank angle up to 70.1 ° at 40 %, g force -0.12 to 2.83 g at 87 %, −0.85 points

Next time

Departure

Lower the nose only a little and let the speed build; a steep nose-down attitude trades height for speed.

What happened: The nose went down by up to 20° to accelerate, where 15° is enough.

Watch for: Attitude: nose no lower than 15° while accelerating.

See Departure Transition

Arrival

Pick a mark on the ground ahead and hold it with small cyclic pressures, correcting the moment it starts to move.

What happened: In the hover before landing the helicopter moved over the ground at 12 kt on average, where a steady hover stays under 5 kt.

Watch for: A fixed point on the ground just ahead, held still in the windscreen.

See Arrival Hover

A slow, steep descent with power applied can lead to vortex ring state, where the helicopter descends into its own downwash. Keep some forward speed until you're close to the ground. That condition and its recovery are worth studying on their own.

Flight narrative

The Boeing CH-47 Chinook taxied to runway 10R at KMRY Monterey Peninsula Airport and commenced its departure roll. The takeoff roll covered 48 m, representing 2 % of the runway, and the aircraft lifted off at 2 kt. Ambient conditions were 19 °C with wind from 269° at 18 kt, including a 7 kt crosswind component and a 16 kt tailwind.

After liftoff the helicopter began its first enroute climb overhead Del Rey Oaks, California, ascending from 1,182 ft asl to 2,850 ft asl, a gain of 1,668 ft achieved in 2 minutes while covering 4 nm.

A descent then commenced 3 miles east of Del Rey Oaks, reducing altitude from 2,815 ft asl to 1,629 ft asl, a loss of 1,185 ft over 2 minutes and 4 nm.

The next climb segment started 4 miles southwest of Spreckels, California, where the aircraft rose from 1,633 ft asl to 2,501 ft asl, an increase of 868 ft in 2 minutes across 2 nm.

A level cruise followed 2 miles east of Del Rey Oaks, lasting 2 minutes and covering less than 1 nm.

The flight then entered a descent 2 miles east of Del Rey Oaks, descending from 2,099 ft asl to 1,373 ft asl, a decrease of 726 ft in 2 minutes while traveling 3 nm.

A second level cruise segment occurred again 2 miles east of Del Rey Oaks, lasting 2 minutes and covering less than 1 nm.

The final descent began 2 miles northeast of Del Rey Oaks, bringing the aircraft from 1,201 ft asl to 609 ft asl, a loss of 592 ft in 2 minutes over less than 1 nm.

Overall, the flight covered a total distance of 17 nm, required 27 minutes of elapsed time, and consumed 1,632 kg of fuel.
