What type of guidance does a precision approach provide?

A precision approach provides both lateral and vertical guidance, which is essential for ensuring safe and accurate landings. This type of approach typically utilizes an Instrument Landing System (ILS), which includes localizer signals to provide lateral guidance that helps align the aircraft with the centerline of the runway, and glide slope signals for vertical guidance that assists in maintaining the correct descent path towards the runway.

Lateral guidance ensures that the aircraft remains on the correct horizontal course, while vertical guidance helps the pilot maintain the appropriate descent angle, which is crucial especially in low visibility conditions. This dual guidance allows for a more precise approach, enhancing safety during the landing phase.

In contrast, other options refer to guidance types that do not cover the complete set of requirements for a precision landing. Therefore, the combination of both lateral and vertical guidance in a precision approach emphasizes the system's capability to provide a comprehensive navigational aid for pilots during landing.
