Distance Measuring Equipment (DME) provides pilots with distance (slant range) between the aircraft and ground station. Signals transmitted between an aircraft and a DME ground beacon enables the aircraft to accurately determine its distance from the ground beacon. DME is one of the primary navigation aids in an airways system.
For maximum performance and safety, the DME is designed with the latest state of the art technology featuring completely independent transponders and dual monitoring systems.
For ease of maintenance, the parameters of all the modules are easily configurable and viewable in the respective front panel displays.
DME 100P can handle over 100 aircrafts simultaneously.
