Which of the following describes the altitude limitation regarding RPAS operations?

The statement regarding altitude limitation in RPAS (Remotely Piloted Aircraft Systems) operations, indicating that greater altitude is only permitted under regulations, is accurate because regulatory frameworks, such as those set by aviation authorities, typically establish specific altitude limits for safety and separation from manned aircraft. These regulations take into account factors like airspace classification and the purpose of the drone operation.

For example, many jurisdictions allow RPAS to operate at higher altitudes but may impose restrictions that require the operator to maintain a certain distance below certain air traffic levels, particularly around airports and populated areas. Additionally, any authorization to exceed standard altitude restrictions typically requires explicit permission from the relevant regulatory authority, ensuring that operations are conducted safely within the established airspace structure.

In this context, the other options misrepresent the rules surrounding RPAS altitude limitations. There are specific authorizations needed rather than a blanket restriction or allowance without consideration of regulations.
