What is the minimum safe altitude (MSA) for the VOR/DME or GPS-A at 7D3 centered on?

The minimum safe altitude (MSA) for the VOR/DME or GPS-A at an airport is typically determined based on the surrounding navigational aids to ensure safe operation within the airspace. In this case, the MSA at 7D3 is centered on the White Cloud VOR/DME.

Using the White Cloud VOR/DME as the reference point ensures that aircraft operating in this area are provided with a minimum altitude that guarantees terrain and obstacle clearance while navigating to or from 7D3. This is critical for maintaining safety, especially in areas that may have varying elevations and obstacles that could pose risks during approaches and departures.

Selecting the MSA centered on this navigational aid allows pilots to receive accurate distance and directional information, which is essential for ensuring they remain at or above the minimum altitude while flying in the vicinity of the airport. The significance of this lies in the role of VOR/DME as a reliable source of navigation data, contributing to the overall safety and efficiency of flight operations.
