Final answer:
A non-precision approach is an aviation instrument approach procedure that does not provide vertical guidance. It relies on navigational aids for horizontal navigation and visual cues for descent and landing.
Step-by-step explanation:
A non-precision approach is an aviation instrument approach procedure that does not provide vertical guidance, typically relying on the pilot's skill and visual cues for descent and landing. It involves using navigational aids such as VOR (VHF Omni-Directional Radio Range) or NDB (Non-Directional Beacon) to navigate horizontally toward the runway.
During a non-precision approach, the pilot follows a specific path indicated by the navigational aids, maintaining a constant altitude until reaching a specified point called the missed approach point. From there, the pilot has to visually acquire the runway or make a missed approach if the runway is not in sight
