All General Aviation aircraft, which have the AVRO airfield as their destination, are subject to PPR to be compulsorily requested at least 24 hours before the flight departure to one of the references indicated in the Contacts. Incoming flights are only accepted on weekends and public holidays, if the tower is staffed, even by contacting the Rivoli Radio frequency at least 5 minutes before ETA.
Traffic is not subject to the issue of a PPR if the flights are: basic, ambulance/humanitarian, rescue and emergency.
