Question 1 of 27070

What is the frequency range of the Distance Measuring Equipment (DME) used to indicate an aircraft’s slant range distance to a selected ground-based navigation station?

🔍 Key Concepts

• Understand what Distance Measuring Equipment (DME) is used for in aviation/marine navigation (slant range distance from aircraft to station). • Recall which frequency bands are typically used for VHF navigation (VOR/LOC) versus UHF systems like DME and TACAN. • Know the normal frequency pairing between VOR/ILS frequencies and DME frequencies.

💭 Think About

• Which of these answer ranges look like VHF navigation frequencies used for VOR or localizer, and which look like UHF frequencies used for DME/TACAN? • If DME works together (paired) with VOR/ILS, does that mean it must be on the same band as VOR, or is it on a different band that is automatically paired? • Look at the numerical values: which range is clearly much higher, corresponding to UHF rather than VHF or ILS glideslope bands?

✅ Before You Answer

• Identify which ranges fall into VHF aeronautical navigation band (~108–118 MHz). • Identify which range is in the UHF band around 1 GHz, commonly associated with DME/TACAN. • Eliminate any ranges you know are associated with ILS marker beacons or glideslope, not DME.
