What held you back

Enroute Climb — bank angle up to 65.0 ° at 50 %, g force 0.60 to 1.90 g at 89 %, −7.02 points
Departure Transition — Sank at up to 655 fpm while accelerating away at 0 %, bank angle up to 27.7 ° at 58 %, −6.65 points

Next time

Departure

Lower the nose no further than 15° and add a little collective as the speed builds.

What happened: The nose went down by up to 20° to accelerate, and the helicopter sank at up to 655 fpm. A steep nose-down attitude trades height for speed, and sink is what usually follows.

Watch for: Attitude: nose no lower than 15°; vertical speed level or climbing.

See Departure Transition

Arrival

Start the descent earlier and hold a steady, moderate rate with collective, so there is no steep drop to stop near the ground.

What happened: The approach reached 3,018 fpm of descent, against 800 fpm for full marks.

Watch for: Vertical speed: no more than 800 fpm on the approach.
