Final answer:
Vision aids can be used during unmanned flight for situational awareness. UAVs can use cameras and sensors to gather real-time visual data, improving monitoring and response capabilities.
Step-by-step explanation:
Vision aids can be used momentarily for situational awareness during unmanned flight. For example, pilots of unmanned aerial vehicles (UAVs) can use cameras and sensor systems to gather visual information and navigate through different environments. These vision aids provide real-time data and images, allowing operators to monitor their surroundings and make informed decisions to avoid obstacles or potential dangers.
In the case of 24-hour monitoring using drone technology, UAVs equipped with night vision cameras or thermal imaging sensors can help detect and track human incursions on the site. These vision aids enhance situational awareness and enable quick response to address and prevent human encroachments on the area.
