No idea why it says so. ENAC is the party for which the information is collected.
Here is another aviosuperficie that has a detailed form for every flight, and the pilot has to await conformation after sending the form. At least this is a webform. The „briefing package“ is a mere 21 pages. Worse than some UK airfields…
Here is another airfield that uses essentially the same form as Bedizzole. It seems to be becoming some sort of standard used by many airfields.
As long as it can remain only a PN.
Some central actor like AOPA Italy should do a central webform for all where you fill all the needed informations and just select the aviosuperficie in question.
It‘s not a PN, it is always a permission. But that of course was also the case with the previous regulation. It‘s private land after all.
