b. Noncommon Route/Portion. That segment of a North American Route between the inland navigation
facility and a designated North American terminal.

the noncommon route begins or ends.
d. Coastal Fix. A navigation aid or intersection where an aircraft transitions between the domestic route
structure and the oceanic route structure.
NORTH AMERICAN ROUTE PROGRAM (NRP)- The NRP is a set of rules and procedures which are
