Resulting Operational and Functional Requirements
This OSED addresses the operational services and environments for the C2 Link System
for the two scenarios described in Section C.6. Linear infrastructure inspection (overflight
of linear infrastructure along a known route from point-to-point) and Aerial Survey
(overflight of objects of interest on mission-specific routes involving a round trip from the
takeoff point). These CONOP’s address operations:
Over people and structures in urban, suburban, and rural environments.
Transit of Class G, E (below A), D, C, and B airspace.
Takeoff and Landing in Class G and D airspace.
The follow-on version of this MASPS is planned to address transit operations in Class A
and Class E above A (60,000’ MSL and above) and UA operations at Class C and B
airports. Neither MASPS is planned to address Oceanic or Remote airspace ( e.g., Alaska
outside the coverage of en route radars). The following operational and functional
requirements were derived based on the selected CONOPS and scenarios but are intended
to address all types of operations in the three bulleted environments described above.
The definitions used for the Operational Requirements and Functional Requirements are
based on ones from the MITRE Systems Engineering Guide .
Operational Requirements – Characteristics of the C2 Link System that are
required to enable the UAS to operate safely and efficiently in the U .S.
National Airspace System (requirements are driven by the operational
environment) and meet the goals of the UAS users.
Functional Requirements – Characteristics of the C2 Link System that
enable it to deliver the operational capabilities required during specific
scenarios (requirements driven by the activities to accomplish the use cases)
within the CONOPS.
From these definitions, it should be noted that the Operational Requirements are designed
independent and the Functional Requirements document how the C2 Link System will
enable the UAS to meet those Operational Requirements.
Operational Requirements (OR)
Based on the OV and SV developments for the Linear Inspection and the Media and
Incident Reporting scenarios (see Section C.7) and the assessment of the WG-2 team, the
best set of operational requirements for the C2 Link System for all five CONOPS (see
APPENDIX A.6.3) are as follows:
OR-1 describes the requirements that would be applicable to all UAS operating in the NAS.
These requirements are derived from the operational activity diagram (OV-5) as described
in Section C.7.2.
OR-1: The C2 Link System shall support the remote pilot’s control of the UA while
conducting authorized operations.
OR-1.1: The C2 Link System shall support the remote pilot’s ability to aviate the
UA through all phases of flight.
OR-1.2: The C2 Link System shall support the remote pilot’s ability to
communicate with other aircraft (if an ATC radio is installed on UA).
OR-1.3: The C2 Link System shall support the remote pilot’s ability to navigate
OR-1.4: The C2 Link System shall support the remote pilot’s ability to remain
DAA well clear (DWC).
