What is the altitude range for controlled Low-Level Airways (LLAs)?

Controlled Low-Level Airways (LLAs) are designated airspace corridors that provide controlled flight guidance to pilots operating at lower altitudes. The defined altitude range for these airways specifically starts from 2,200 feet Above Ground Level (AGL) up to 18,000 feet Above Sea Level (ASL).

This range allows for effective air traffic management, providing adequate separation from terrain and obstacles while accommodating various types of aircraft, including general aviation and commercial air traffic. The altitude thresholds are set to ensure safety and efficiency as aircraft transition from low-level operations to more structured airways that typically begin at 18,000 feet ASL, where High Altitude Air Traffic Control procedures become applicable.

Other altitude ranges mentioned in the options either fall below the established minimum for LLAs, exceed maximum operational limits, or do not align with regulatory standards set by aviation authorities for low-level controlled airspace. Understanding this specific range is crucial for pilots navigating air traffic systems and maintaining adherence to airspace regulations.
