• Small UAS forecast – 7M total, 2.6M commercial by 2020 • Vehicles are automated and airspace integration is necessary • New entrants desire access and flexibility for operations • Current users want to ensure safety and continued access • Regulators need a way to put structures as needed • Operational concept being developed to address beyond visual line of sight UAS operations under 400 ft AGL in uncontrolled airspace using UTM construct 4
• UTM is an “air traffic management” ecosystem for uncontrolled airspace • UTM utilizes industry’s ability to supply services under FAA’s regulatory authority where these services do not exist • UTM development will ultimately identify services, roles/responsibilities, information architecture, data exchange protocols, software functions, infrastructure, and performance requirements for enabling the management of low-altitude uncontrolled UAS operations UTM addresses critical gaps associated with lack of support for uncontrolled operations How to enable multiple BVLOS operations in low-altitude airspace? 5
• FAA maintains regulatory AND operational authority for airspace and traffic operations • UTM is used by FAA to issue directives, constraints, and airspace configurations • Air traffic controllers are not required to actively “control” every UAS in uncontrolled airspace or uncontrolled operations inside controlled airspace • FAA has on-demand access to airspace users and can maintain situation awareness through UTM • UTM roles/responsibilities: Regulator, UAS Operator, and UAS Service Supplier (USS) • FAA Air Traffic can institute operational constraints for safety reasons anytime Key principle is safely integrate UAS in uncontrolled airspace without burdening current ATM 6
Principles Key UAS-related services Users operate in airspace volumes as Authorization/Authentication specified in authorizations, which are Airspace configuration and static and issued based on type of operation and dynamic geo-fence definitions operator/vehicle performance Track and locate UAS stay clear of each other Communications and control (spectrum) UAS and manned aircraft stay clear of Weather and wind prediction and sensing each other Conflict avoidance (e.g., airspace UAS operator has complete awareness of notification) airspace and other constraints Demand/capacity management Public safety UAS have priority over other Large-scale contingency management UAS (e.g., GPS or cell outage) 7
