These functional requirements could support the development of a minimum set of policies, procedures and standards by the Federal Aviation Administration (FAA) and various standards organizations. It is envisioned that this comprehensive body of work will enable the FAA to establish and approve regulations to govern safe operation of UAS in the NASon a routine or daily \"file and fly\" basis.  \nThe approach used to derive the functional requirements found within this FRD was to decompose the operational requirements and objectives identified within the Access 5 Concept of Operations (CONOPS) into the functions needed to routinely and safely operate a HALE UAS in the NAS. As a result, four major functional areas evolved to enable routine and safe UAS operations for an on-demand basis in the NAS. These four major functions are: Aviate, Navigate, Communicate, and Avoid Hazards. All of the functional requirements within this document can be directly traceable to one of these four major functions. Some functions, however, are traceable to several, or even all, of these four major functions. These cross-cutting functional requirements support the “Command / Control ”function as well as the “Manage Contingencies ”function. The requirements associated to these high-level functions and all of their supporting low-level functions are addressed in subsequent sections of this document.  \nStatus:  \n\n| Access 5-Approved |\n| --- |\n|  |\n\nLimitations on use:  \nThis document is an approved Access 5 Project position on the functional requirements for HALE UAS operations in the NAS for Step 1 (operations above FL430).  \nFunctional Requirements Document For HALE UAS Operations in the NAS  \nStep 1  \nVersion 3, January 2006  \nPrepared by:  \nAccess 5 Systems Engineering  \nand Integration Team  \nApproved by:  \nJeffery E.
