What is the altitude range of low-level airways?

The altitude range of low-level airways is established to ensure safe routing and separation of aircraft operating in lower altitude phases of flight, typically below the higher altitude airways that are used by larger commercial aircraft.

The correct answer indicates that low-level airways operate from 2,200 feet above ground level (AGL) to 17,999 feet above sea level (ASL). This range is significant for areas where more general aviation and smaller aircraft operate, offering a structured framework for navigation and communication to enhance safety in less congested airspace.

Low-level airways are designed for use by aircraft that are flying at lower elevations, such as regional flights or smaller general aviation aircraft, which often need to avoid busy higher altitude airways used for international and commercial flights.

Beyond this range, the airspace transitions to higher airways, which have different requirements and operations. Understanding the specific altitude range is crucial for pilots in ensuring compliance with air traffic control regulations and for effective flight planning within low-level navigation routes.
