What frequency range is typically associated with Distance Measuring Equipment (DME)?

• A. 400-450 MHz
• B. 800-900 MHz
• C. 962-1213 MHz
• D. 1500-1650 MHz

Answer: (C)

Distance Measuring Equipment (DME) operates within the frequency range of 962 to 1213 MHz. This system plays a crucial role in aviation navigation by providing pilots with distance information relative to a DME station. The DME transmits a signal that allows the aircraft to calculate the distance based on the time it takes for the signal to travel to the ground station and back. The 962 to 1213 MHz range is specifically allocated for aviation use, ensuring that DME signals are reliable and not subjected to interference from other frequency bands. This frequency range is part of the VHF and UHF spectrum and is vital for aircraft to maintain accurate positional awareness during flight.
