What frequency range does the Distance Measuring Equipment (DME) operate within?

• A. 800 MHz to 900 MHz
• B. 962 MHz to 1213 MHz
• C. 500 MHz to 700 MHz
• D. 1300 MHz to 1500 MHz

Answer: (B)

Distance Measuring Equipment (DME) operates within the frequency range of 962 MHz to 1213 MHz. This equipment is used in aviation to determine the distance between an aircraft and a specific ground station. The DME transmits signals that the aircraft's onboard equipment receives and uses to calculate the distance based on the time it takes for the signal to travel to the station and back. This specific frequency range is designated by the International Telecommunication Union (ITU) for aviation use, ensuring that it does not interfere with other communication systems. By utilizing this frequency allocation, DME systems can operate effectively and reliably in conjunction with other navigation tools, providing essential data for aircraft positioning and navigation. The other frequency ranges mentioned do not correspond with the operational specifications for DME, which is why they would not be correct choices. Understanding the designated frequency range is crucial for anyone involved in aviation communications and navigation.
