Avoiding drop zones
Hi all,
I visited an airflied today which has a DZ very near to the runway. There were no meatbombers at the time because of cloud. There was no ATC, just "XXXX Radio". In this situation I have two questions:
1. What is the system to let pilots know it's about to start raining people?
2. How large should the circuit pattern be to avoid the DZ?
Thanks
