What is the primary purpose of the obstacle identification system (OIS)?

The primary purpose of the obstacle identification system (OIS) is focused on recognizing and assessing terrain features that could pose a risk, particularly during critical phases of flight such as departures and arrivals. By accurately identifying these obstacles, the OIS plays a crucial role in enhancing flight safety by allowing pilots to make informed decisions regarding their flight path.

This system targets safety by ensuring that pilots are aware of potential terrain hazards, enabling them to avoid obstacles that could lead to accidents during takeoff or landing. The effectiveness of an OIS in increasing situational awareness is vital for safe operation, especially in areas where terrain might not be easily identifiable visually.

Other functions, such as navigation assistance, mid-air collision prevention, or communication with air traffic control, although important in aviation, do not specifically outline the core purpose of the OIS. The OIS is tailored to focus on obstacle awareness, which is essential for maintaining safety as aircraft maneuver around potential hazards.
