The FAA updated this Concept of Operations (ConOps) to document the continued maturation of UTM and share the vision with government and industry stakeholders. UTM ConOps V2.0 continues to focus on UTM operations below 400 feet above ground level (AGL), but also addresses increasingly more complex operations within and across both uncontrolled (Class G) and controlled (Classes B, C, D, E) airspace environments. V2.0 updates and expands the set of operational scenarios, describing more complex operations in denser airspace, including beyond visual line of sight (BVLOS) operations in controlled airspace. V2.0 includes updated descriptions of/approaches to several UTM components, including UAS Volume Reservations (previously referred to as Dynamic Restrictions), Performance Authorizations, data archiving and access, USS service categories, UTM/ATM contingency notification, and security aspects associated with UTM operations. V2.0 also introduces new topics including Airspace Authorization for BVLOS flight within controlled airspace, UTM architecture support to remote identification of UAS Operators, and standards development efforts with industry as an integral part of enabling UTM operations.
