Which terrain flight mode hugs the terrain to stay low and stealthy?

• A. Nap of the Earth (NOE)
• B. Contour
• C. Hover
• D. Level Flight

Answer: (A)

Hugging the terrain to stay low and stealthy is achieved by following the ground’s shape as closely as possible. Nap of the Earth is the mode that does exactly that—skimming the surface and matching every contour, ridge, and valley to stay as low as possible and reduce visibility and radar detection. This extreme terrain-following path is what makes it the best choice for stealthy, low-altitude flight. Other modes either maintain a fixed height above the terrain or stay in one place: contour flight follows terrain with a small, consistent clearance but not as close as NOE; hover holds a stationary position at a set altitude; level flight remains at a constant altitude and direction, not adapting to terrain.
