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

To complete the VOR/DME-A procedure, having one VOR receiver and a DME is essential. The VOR (VHF Omnidirectional Range) receiver provides azimuth information, allowing the pilot to determine their position relative to the VOR station. This is crucial for navigation along the approach path. The DME (Distance Measuring Equipment) complements this by providing distance information from the VOR station, which is critical for determining how far the aircraft is from the VOR and, consequently, how to manage the approach.

The combination of these two pieces of equipment allows a pilot to follow the procedure accurately and maintain a safe and controlled descent profile. The use of a single VOR receiver enables the pilot to track the radial easily, while the DME gives real-time distance data, enhancing situational awareness during the approach. Therefore, this pairing is specifically tailored to fulfill the requirements of the VOR/DME-A procedure effectively.
