Why is TSO important?

A Technical Standard Order (TSO) is a minimum performance standard for specified materials, parts and appliances used on civil aircraft. When a company is authorized to manufacture a material, part or appliances to a TSO standard, this is referred to as TSO authorization. When a company receives a TSO authorization, it is assured that the product meets these minimums in both design and production. Bose Corporation meets all and exceeds many TSO requirements.
