The reason for undertaking the version 2.0 update was to expand the document’s content, engage subject matter experts not previously involved, identify potentially overlooked gaps, track progress by SDOs to address the recommendations contained in version 1.0, review priorities, and otherwise incorporate feedback. Of 78 issue areas examined, 71 open gaps were identified, meaning there is currently no published standard or specification that covers the issue in question. Each gap includes a corresponding recommendation for action, along with a priority level for producing a standard and the name of a suggested organization(s) that can address the need. Of the open gaps, 47 have been identified as high priority, 21 as medium priority, and 3 as lower priority. In 53 cases, additional R&D is needed. Two version 1.0 gaps were closed, 3 were withdrawn, and 16 new gaps were added.
Many sections of the document were substantially revised or expanded, including such areas as: categories of spectrum applicable to command and control (C2) link and communications, continued operational safety, UAS detection and mitigation, and public safety tactical operations. New gap analysis sections were added related to:
- Blockchain for UAS
- Recreational Operations
- Design and Operation of Aerodrome Facilities for UAS
- UAS Service Suppliers (USS) Process and Quality
- Implementing UAS for Hydrocarbon Pipeline Inspections
- Implementing UAS in Airport Operations
- Commercial Cargo Transport via UAS
- Commercial Passenger Air Taxi/Transport via UAS (both short- and long-haul flights)
- Commercial Sensing Services
- Use of small UAS for News Gathering
- UAS for Emergency Management and Disasters
- Standardization of Data Formatting for small UAS Public Safety Operations
It is envisioned that future work will entail promotion of the roadmap and establishing a mechanism to assess progress on its implementation.
