Enabling unrestricted UAS airspace access: Performance based navigation

The goal of the integration of Unmanned Aircraft Systems (UAS) in the National Airspace System (NAS) is to achieve “file-and-fly” access to all classes of airspace. This means the UAS will fly without limitations or waivers in airspace shared with other manned and unmanned aircraft. In the case of large UAS operating in a similar manner to transport category aircraft in terminal, en-route and oceanic/remote environments, this includes the ability to perform area navigation.
