So, how do pilots manage to land their aircraft safely and accurately without even being able to see where theyre going? The ILS (Instrument Landing System) uses radio signals to help pilots align the aircraft accurately on their approach to a runway. Lets learn more about this system!

Area Navigation (RNAV) is a way for pilots to know where they’re going without needing help from the ground. Before RNAV, pilots had to rely on radios (NAVAIDs) and antennas on the ground such as VORs (Very High-Frequency Omnidirectional Range) and NDBs (Non-Directional Beacons). What Are RNAV Approaches? How Does RNAV Work?

This identifies the critical area for the instrument landing system, located near the ILS antenna array, where an airplane on the ground (or vehicle) in that space could interfere with the radio signals for airplanes flying an ILS instrument approach. ILS critical area boundary sign

Using the VASI is crucial as it gives you safe obstruction clearance within 10 degrees of either side of the runway centerline and around four nautical miles from the runway threshold. nautical miles from the runway threshold. VASI systems also are typically cheaper to install and maintain than more advanced systems like PAPI.
