What minimum navigation equipment is required to complete the VOR/DME-A procedure?

To successfully complete the VOR/DME-A procedure, the minimum required navigation equipment includes one VOR receiver and Distance Measuring Equipment (DME). This combination is essential for accurately navigating the procedure, as the VOR receiver provides lateral guidance, allowing the pilot to determine their position relative to the VOR station. Simultaneously, the DME provides the pilot with distance information from the VOR station, which is critical for adhering to any altitude or distance restrictions during the approach.

While a single VOR receiver alone would allow for navigation to the VOR station, it would not provide the necessary distance information to complete the procedure safely and effectively. The same applies to having two VOR receivers or using a combination of VOR and GPS; these options do not meet the specific requirements of the VOR/DME-A approach, which mandates the use of DME for distance calculations. Therefore, the proper equipment configuration to execute this procedure is the combination of a VOR receiver and DME.
