How Should Large Facilities Plan Acoustic UAV Detection Without Compromising Safety?

Acoustic sensing can be assessed as a context-dependent information source whose usefulness varies with the facility environment, lawful data inputs and programme objectives. It should be considered alongside other authorised contexts such as RF, radar, EO/IR or fusion only where those inputs are permitted and appropriate; none should be described as guaranteed, interchangeable or sufficient on its own. Planning language should avoid fixed performance promises and instead define what evidence can be reviewed, what uncertainty remains, and how conflicting information is labelled for people to assess.

Close the planning loop with written validation that records assumptions, authorised inputs, protected services, safety offsets, uncertainty, human-review responsibilities and compliance decisions. Validation should be proportionate to the site and should explain how acoustic information will be interpreted without turning it into an automatic conclusion or response instruction. A New Ark project conversation is therefore centred on traceability and responsible integration: stakeholders can approve, revise or reject the concept using evidence and governance rather than unsupported coverage or performance claims.
