In plain language

If you fly in higher-risk environments (such as controlled airspace, high population areas, or with aircraft over 150 kg), your operational processes and manuals must be significantly more robust than for low-risk flights.

Requirement as structured

The robustness of an operator's manuals and processes should scale with the risk and complexity of the operations, with higher-risk operations requiring more robust processes.

Original regulatory text

Lower-risk operations (low altitude, low population density, and uncontrolled airspace) require less robust processes. As the risk levels increase the expectations of a more robust processes increase as well. Higher-risk operations (over 150KGs, high altitude, high population density, in controlled airspace with complex/multiple aircraft, and remote operating centers) usually require processes to meet the elevated risk and robustness levels...
