| 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 |
| 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 |
| The initially high airflow increases the rotor thrust until the lower air density reduces the rotor thrust again |
| The conversion of energetic air into kinetic rotor energy decreases continuously with increasing density altitude |
