What is the lateral coverage of localizer at 4500 ft AGL?

The lateral coverage of a localizer at 4500 feet Above Ground Level (AGL) is often understood in terms of the amount of airspace it effectively covers to either side of its centerline. The option specifying 10° each side indicates that the localizer provides guidance over a total angle of 20° of lateral coverage.

This 10° coverage on each side is consistent with standard localizer performance for instrument landing systems, which typically have a defined lateral accuracy and coverage. It allows pilots to receive precise lateral guidance to align the aircraft with the runway during approach and landing, making it essential for ensuring safe landings in varying conditions.

This specification is derived from standard aviation practices and regulations governing ILS systems, which have established these angles for optimal performance and safety in approach procedures. Understanding these parameters is crucial for pilots in terms of navigation and maintaining the correct approach path to the runway.
