Sensor technologies such as radar, lidar, and optical cameras are utilized to detect the interface more reliably. However, these systems can be impeded by water surface conditions like choppiness, foam, or algae blooms, which obscure the boundary. Variations in water surface reflectivity and light conditions also complicate sensor readings.

Environmental factors further influence detection accuracy. Water currents, waves, and tides constantly alter the water surface, making it difficult for sensors to maintain stable readings. Weather conditions such as fog, rain, or snow can drastically reduce sensor effectiveness, increasing the risk of misidentifying the interface. Overcoming these challenges requires sophisticated technology and precise calibration to ensure consistent navigation safety for amphibious aircraft.
