2. Noncommon Route/Portion. That segment of a North American Route between the inland navigation facility and a designated North American terminal.
3. Inland Navigation Facility. A navigation aid on a North American Route at which the common route and/or the noncommon route begins or ends.
4. Coastal Fix. A navigation aid or intersection where an aircraft transitions between the domestic route structure and the oceanic route structure.
