What technique does a Precision Approach use for landing?

A Precision Approach utilizes both azimuth and glide path information to guide an aircraft safely to the runway during landing. This approach relies on highly accurate navigation aids, like the Instrument Landing System (ILS), which provides precise lateral (azimuth) and vertical (glide path) guidance.

The azimuth component helps pilots align the aircraft's approach with the runway centerline, ensuring proper lateral alignment. Meanwhile, the glide path information assists in maintaining the correct descent angle, allowing for a stable and controlled descent toward the runway. This combination is essential for operations in low-visibility conditions where visual references may be limited.

In contrast, visual aids alone would not offer the same level of precision required for landing, particularly under poor weather conditions. Azimuth information by itself would provide lateral guidance, but without glide path information, pilots would lack the vertical control necessary for a safe landing. Error correction algorithms, while useful in various contexts, do not specifically define the technique employed in a precision approach for landing.
