Which mode is essential for the functioning of the DME in aircraft navigation?

• A. Standby mode
• B. transmit mode
• C. Manual mode
• D. Auto mode

Answer: (D)

The functioning of the Distance Measuring Equipment (DME) in aircraft navigation is critically dependent on its auto mode. In this mode, the DME automatically calculates the distance between the aircraft and the ground-based DME station, facilitating real-time updates and accuracy in distance measurements. Auto mode allows the system to continuously receive signals from the DME station, ensuring that the information displayed to the pilot is both timely and reflective of the aircraft's current position relative to the navigation aid. In addition to supporting essential navigation functions, auto mode integrates seamlessly with other avionics systems, enabling effective coordination and utilization of navigation data. This coordination is invaluable in complex flight environments, where precise distance measurements are essential for safe maneuvering and navigation.
