What type of NAVAID transmits very high frequency navigation signals in a 360-degree azimuth orientation to magnetic north?

The correct answer is VOR, which stands for VHF Omni-directional Range. A VOR is a type of ground-based navigational aid that transmits radio signals in all horizontal directions, creating a 360-degree coverage pattern. This allows aircraft equipped with VOR receivers to determine their bearing relative to the VOR station, which is aligned with magnetic north.

VORs are utilized by pilots for en route navigation as well as for instrument approaches, helping to ensure aircraft maintain their intended flight paths. They provide a reliable means of navigation that is particularly valuable in poor visibility conditions.

In contrast, an NDB (Non-Directional Beacon) transmits signals that can be received from various directions but does not offer the same degree of precise navigation relative to magnetic north. GPS offers navigation capability through satellite signals and does not rely on ground-based stations for direction. An ILS (Instrument Landing System) provides guidance for landing approaches, but it is not used for general en route navigation as VORs are.
