Which airway includes an MRA and has its altitude listed as 5,000 feet?

• A. V18, HEDUD (5,000')
• B. V535 (2,000')
• C. V74 (1,000')
• D. V427 (3,000')

Answer: (A)

Understanding how airways are annotated helps you pick routes that meet reception and altitude requirements. An MRA, the Minimum Receiving Altitude, shows the lowest altitude at which navigation signals along that airway segment can be reliably received. When an airway listing includes an MRA, the altitude shown with the segment indicates that MRA value. In this question, the only airway listing that shows an MRA and lists the altitude as 5,000 feet is the one for V18 via HEDUD, with (5,000'). The other airways list different altitudes (2,000', 1,000', 3,000') and do not indicate an MRA, so they don’t meet both criteria.
