What is the minimum equipment required to safely complete a VOR/DME or GPS-A procedure when flying to Baldwin?

To safely complete a VOR/DME or GPS-A procedure, having one VOR receiver and one DME receiver is essential. This combination allows the pilot to obtain the necessary navigational information required for an instrument approach. The VOR receiver is used to determine the aircraft's position relative to the VOR station, while the DME (Distance Measuring Equipment) provides the distance from the station. Together, these instruments facilitate a precise approach to the airport, ensuring that the pilot can maintain the correct course and distance throughout the procedure.

In contrast, relying solely on two VOR receivers may not provide the distance information crucial for the approach. A single GPS receiver offers modern navigation benefits but cannot support the VOR/DME procedure, which specifically requires distance data from the DME. Lastly, having a DME receiver alone does not fulfill the need for directional guidance that the VOR receiver provides in this context. Thus, the combination of a VOR receiver and DME receiver is the minimum equipment required for safely executing the procedure.
