It is not a radio navigation aid which of the following is not a navigation aid?

Explanation:
Navigation aids are systems that transmit signals to help you determine position, bearing, or distance. A volt-ohm meter is not one of these; it’s a tool for measuring electrical properties such as voltage, current, and resistance in the aircraft’s systems. It doesn’t provide any navigation information. In contrast, VOR offers a fixed azimuth to or from a station, DME gives distance to a station, and ADF provides a bearing to a nondirectional beacon. So the volt-ohm meter is the non-navigation instrument, while VOR, DME, and ADF are radio navigation aids.
