What is a precision approach?

A precision approach is defined as an approach procedure that offers both lateral and vertical guidance to the runway, which is essential for ensuring that the aircraft is aligned correctly when descending towards the runway. This type of approach typically utilizes instrument landing systems (ILS) that provide pilots with precise information about their position in relation to the runway.

The lateral guidance directs the aircraft along the correct flight path, while the vertical guidance helps ensure that the descent rate is appropriate, allowing for a stable approach. This dual guidance system is particularly valuable in low-visibility conditions, where pilots rely heavily on instruments to land safely.

Given that precision approaches incorporate both forms of guidance, they reduce the pilot's workload and enhance the safety and accuracy of landings, making it a crucial part of instrument flight operations.
