NOTE:
When radar control of fixed-wing aircraft is being provided by a Navy ship or shore station in airspace managed by a FACSFAC, continuous two-way communication is required between that ship or shore station and the FACSFAC. Also the FACSFAC must maintain two-way communication with the appropriate FAA facility as required


North American Route Program:

  • The latest version of Advisory Circular 90-91, North American Route Program (NRP), provides guidance to users of the National Airspace System (NAS) for participation in the NRP
  • All flights operating at or above FL 290 within the conterminous United States and Canada are eligible to participate in the NRP, the primary purpose of which is to allow operators to plan minimum time/cost routes that may be off the prescribed route structure
  • NRP aircraft are not subject to route-limiting restrictions (e.g., published preferred IFR routes) beyond a 200 NM radius of their point of departure or destination

Conclusion:

  • The NRP is a tool for route planning purposes and aircraft participating in the NRP remain limited to a route of flight that can be conducted in accordance with the communication and navigation equipment on board the aircraft
  • The North American Route Program is a joint venture between the Federal Aviation Administration (FAA) and NAV CANADA
