Plain English Summary

1/10 complexity

This order sets the technical design rules for aircraft instruments — the gauges, displays, and measurement devices used in planes.

What it requires:

Aircraft instruments must be designed to meet standards from either the British Standards Institute or the Society of Automotive Engineers (USA).

Who it affects:

Aircraft manufacturers and designers building or modifying planes
Maintenance organisations repairing or replacing instruments
CASA (the aviation safety regulator) approving alternative standards

Flexibility built in: If you want to use a different standard — such as a manufacturer's own specification or standards from another country's aviation authority — you can apply to CASA's Director for approval to use it as an alternative.

Why it matters: This ensures all instruments in Australian-registered aircraft meet rigorous, internationally recognised safety and performance benchmarks, while allowing flexibility for new technologies.
