What does the acronym TSO stand for in aviation?

In aviation, TSO stands for Technical Standard Order. This designation refers to a minimum performance standard that various aviation instruments must meet to be eligible for FAA (Federal Aviation Administration) certification. TSOs are particularly crucial as they ensure that equipment, such as avionics and other components built for aircraft, conform to specified standards set forth by the FAA.

The importance of TSOs lies in their role in enhancing safety and ensuring that equipment can function reliably throughout its operational life. Manufacturers producing equipment that adheres to TSO standards can indicate to consumers and regulatory bodies that their products have been tested against these established benchmarks.

Understanding TSO is essential for anyone involved in aviation maintenance, manufacturing, and regulation, as compliance ensures the reliability and safety of aircraft systems.
