Which type of navigation system uses magnetic headings?

The correct answer is that NDB (Non-Directional Beacon) systems use magnetic headings for navigation. NDB systems provide aircraft with guidance by transmitting a consistent radio signal, which pilots can receive through their onboard equipment. The aircraft’s compass, which operates using the Earth's magnetic field, allows pilots to track the direction of the NDB signal by following the magnetic heading indicated on their instruments.

The reliance on magnetic headings is key in NDB navigation, as pilots must align their aircraft's heading with the bearing to the beacon, which is typically referenced in magnetic terms. This is essential for accurate navigation, particularly when pilots need to follow specific routes or approach procedures that depend on maintaining a certain track relative to the magnetic North.

In contrast, inertial navigation systems do not utilize magnetic headings; instead, they use internal sensors to determine the aircraft's position and velocity based on its last known location. GPS systems rely on satellite data for positioning and do not need magnetic headings, as they provide absolute positional information. VOR (VHF Omnidirectional Range) systems provide directional information using a combination of magnetic headings and VHF signals, but they are not based solely on magnetic headings like NDB systems. Thus, the key distinguishing feature of NDB systems is their
