Non-Precision Approach Procedure

A non-precision approach is a method pilots use to navigate aircraft safely when landing without relying on precise vertical guidance, such as an ILS. Instead, it provides lateral (“side-to-side”) navigation guidance using instruments like VOR, NDB, or GPS. Pilots follow these signals to align the aircraft with the runway. Since it lacks a glide slope indicator, pilots must carefully manage their descent rate and altitude, often using visual cues and fixed minimums for safety. This approach allows landings in various weather conditions, though it generally provides less precise guidance than precision approaches.
