The The Dynamic Regulatory System (DRS) is a comprehensive knowledge center that includes all regulatory guidance material from the Office of Aviation Safety.

DRS combines more than 65 document types from a dozen repositories into a single searchable application. It also includes all information found in the Flight Standards Information System (FSIMS) and the agency's Regulatory Guidance System (RGL). You can browse or search the more than 2 million regulatory guidance documents. A complex search engine serves as the backbone of DRS and allows for basic or very advanced searches, while applying a variety of filters. The system includes pending, current and historical versions of all documents along with their revision history. And to ensure you have the most current documents, it is updated every 24 hours.

DRS is mobile-friendly and users will get the best experience using Chrome or Safari. DRS does not support Internet Explorer.
