... Cavitation plate is a misnomer, as it has nothing to do with propeller cavitation. The proper term is 'anti-ventilation plate' (or 'AV plate' for short), as the plate prevents the surface air from being sucked into the propeller stream, thus ventilating it.
This is in my eyes a very good and important correction...
I suggest we use «AV-Platte» or «AV-plate» from now on...because:

this has theoretically nothing to do with cavitation (when I understand the definition right...please correct if I'm wrong):
Wikipedia says:
Cavitation is the formation and then immediate implosion of cavities in a liquid – i.e. small liquid-free zones ("bubbles") – that are the consequence of forces acting upon the liquid.[1] It usually occurs when a liquid is subjected to rapid changes of pressure that cause the formation of cavities where the pressure is relatively low.
What happens when there is an airflow towards the propeller, this is
ventilation, not cavitiation.
Cavitation occurs when the propeller turns too high and/or has a non-ideal form, as far as I know...
