Definition of DME Arc
A DME arc is a navigational technique used in aviation that involves flying a consistent distance from a radio navigation station or a pre-defined waypoint. It is typically used during the approach phase of a flight when an aircraft is descending to land at an airport.
The DME arc allows the aircraft to maintain a specific distance from the navigation station or waypoint, which is necessary to ensure accurate navigation and safe separation from other aircraft. Pilots can use the DME arc to fly a circular pattern around the station or waypoint, following a pre-determined course and using radio signals to ensure their position.
The DME arc technique requires a sophisticated aircraft navigation system that can accurately communicate with the radio navigation station or waypoint. Pilots must also be able to maintain a constant speed and altitude throughout the arc, as well as make any necessary adjustments to their flight path in response to changing weather conditions or air traffic control instructions.
Overall, the DME arc is a crucial tool for pilots during the approach phase of a flight. It allows for safe and accurate navigation, helping to ensure the safe arrival of the aircraft at its destination airport.
