What was the purpose of navigation aids introduced during instrument flying?

The introduction of navigation aids during instrument flying primarily served the purpose of helping pilots navigate and approach landing safely. These aids were crucial in the development of aviation, especially as flights began to operate in poor visibility conditions. Instruments such as radio navigation beacons, VOR (VHF Omnidirectional Range), and ILS (Instrument Landing System) provided pilots with crucial information about their position relative to the airport and the route, enabling safe and efficient navigation.

Prior to the widespread use of these navigation aids, flying relied heavily on visual cues, which could be unreliable in adverse weather conditions. With the incorporation of these tools, pilots gained the ability to maintain course and make precise approaches to landing, significantly enhancing safety and reliability in aviation operations. This technological advancement laid the groundwork for modern instrument flying, where pilots can confidently navigate even when outside visual references are minimal or nonexistent.
