Which pairing is correct for a DME fix and its MHZ coordinate?

• A. RICKS — MHZ 164038
• B. YAZOO — MHZ 335030
• C. ZAMMA — MHZ 049046
• D. HEDUD — MHZ 266023

Answer: (D)

DME fixes on MAPs are identified by a fix name paired with the DME MHZ frequency that defines its location. The MHZ value is written as three digits before and three after the decimal, so 266023 means 266.023 MHz. For the HEDUD DME fix, the chart shows this exact MHZ value, making it the correct pairing. The other fixes are listed with MHZ values that do not match the charted data for those fixes, so they don’t accurately identify the same DME locations. In practice, you’d use that MHZ value to verify or tune to the correct DME fix during navigation.
