Changeover point (COP)

Definitions

• A point along the route or airway segment between two adjacent navigation facilities or waypoints where changeover in navigation guidance should occur.
• A COP indicates the point where a frequency change is necessary between navigation aids, when other than the midpoint on an airway, to receive course guidance from the facility ahead of the aircraft instead of the one behind. These COPs divide an airway or route segment and ensure continuous reception of navigational signals at the prescribed minimum en route IFR altitude.
