What is the minimum altitude allowed for a helicopter flying directly over a city?

The minimum altitude for a helicopter flying directly over a city is set at 500 feet AGL (Above Ground Level). This regulation is designed to ensure safety for both the helicopter and the ground residents. At this altitude, helicopters can maintain enough height to navigate safely over urban areas while reducing the risks associated with potential emergencies, such as engine failures. The regulation balances the need for operational flexibility and efficiency with public safety concerns, allowing helicopters to operate without significant noise pollution or risk to structures and people below.

The other altitude options are higher than what is generally permitted for urban flying, making them unnecessary and impractical for typical helicopter operations over cities. Higher altitudes, while potentially increasing safety margins in some scenarios, do not align with the specific regulations that allow helicopters to conduct low-level flights in populated areas.
