What should you do before flying near an assembly of over 1000 people?

Obtaining permission from the CAA (Civil Aviation Authority) is necessary before flying near an assembly of over 1000 people due to safety regulations that are designed to protect large groups of individuals on the ground. This requirement is in place because of the increased risk associated with flying over densely populated areas where the potential for injury or damage from a falling aircraft is significantly higher. The CAA has specific guidelines and protocols in place to ensure that any flight in such circumstances is conducted safely and complies with aviation regulations.

While submitting a flight plan may be necessary for certain types of flights, it does not specifically address the safety concerns associated with flying over a large assembly of people. Flying high over the assembly might seem like a safer option, but it does not eliminate the risks involved, as aircraft can still pose a danger even when operating at altitude. Choosing a different flight path could be a sensible precaution, but it might not be sufficient on its own without securing the appropriate permissions from the CAA, which ensures that all necessary safety measures are taken into account. Therefore, obtaining permission from the CAA is the most comprehensive and responsible action to take in this scenario.
