Aircraft navigation systems are crucial for flight safety and efficiency. The role of an aircraft's navigation systems include ¹:

- *VOR (Very High-Frequency Omni-Directional Range)*: Uses ground signals to provide precise location information.
- *GPS (Global Positioning System)*: Utilizes satellites for accurate global positioning, eliminating uncertainties in location.
- *ADF (Automatic Direction Finder)*: Relies on radio beacons to direct aircraft.
- *INS (Inertial Navigation System)*: Uses motion sensors and extensive data to calculate the aircraft’s position internally.

These systems significantly enhance flight safety and efficiency, marking advancements in how we navigate the skies.
