Flight Score
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.
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.
