What describes the NOE mode of terrain flight?

In the context of terrain flight operations, the NOE (Nap-of-the-Earth) mode is characterized by flying as close to the earth's surface as possible while adjusting airspeed as needed to navigate the terrain effectively. This mode is essential for enhancing the aircraft's stealth and reducing the likelihood of detection, as flying low can conceal the aircraft from enemy radar and visual observation. The varying airspeed allows the pilot to respond to changes in the terrain, obstacles, and mission requirements while maintaining a safe, low altitude.

This approach contrasts with other modes of flight where altitude or speed might remain constant, which would not allow the flexibility necessary for safe navigation in environments with variable terrain. The emphasis on staying close to the surface while adjusting speed effectively captures the essence of NOE flight operations.
