Why is a helicopter's climb initially accelerated after an increase of the pitch angle?

Question

Question PPL(H) - Private Pilot License - Principles of Flight (Helicopter)

QuizVDS · Accepted Answer

The inertia of the air increases the effective angle of attack temporarily until an additional component of the climb rate reduces the effective angle of attack again

QuizVDS · Answer

The larger pitch angle causes a decrease and a compression of the airflow until the climb rate corresponds to the induced velocity through the main rotor disc

QuizVDS · Answer

The initially high airflow increases the rotor thrust until the lower air density reduces the rotor thrust again

QuizVDS · Answer

The conversion of energetic air into kinetic rotor energy decreases continuously with increasing density altitude
