True North/South. Magnetic North/South. There are supposedly 11 different Norths and Souths. How do airplanes get us home (to the correct airport) safely?

The general idea of the public is that airplanes use GPS to navigate. However, airplanes, particularly large transport category models, use several navigation systems to go from place A to place B. At the heart of the navigation system is the Inertial Reference System (IRS). Then comes the GPS and other navigational aids such as the VOR (Very High-frequency Omni Directional Range), DME (Distance Measuring Equipment), NDB (Non-Directional Beacon), etc.
