What are the acronyms for the seven non-precision approaches?

The seven non-precision approaches include VOR, VOR/DME, TACAN, LOC, GPS, NDB, and ASR. Each of these acronyms represents a type of navigation aid or approach method that pilots use which does not provide vertical guidance but allows for lateral navigation.

• VOR (VHF Omnidirectional Range) uses radio signals to help pilots determine their position and track along a predetermined flight path.

• VOR/DME (Distance Measuring Equipment) enhances VOR capabilities by providing distance information in addition to directional information.

• TACAN (Tactical Air Navigation) is similar to VOR but is primarily used by military aircraft, providing both distance and bearing.

• LOC (Localizer) is part of an instrument landing system, helping pilots follow the centerline of an airport runway but does not provide vertical guidance.

• GPS (Global Positioning System) is a satellite-based navigation system that pilots can use to make non-precision approaches when necessary.

• NDB (Non-Directional Beacon) is an older navigational aid that transmits a constant radio signal, allowing pilots to determine their bearing and track to or from the station.

• ASR (Airport Surveillance Radar) provides radar information to approach controllers to assist in
