What Terrain flight mode is 25 feet to 80 feet AHO?

What Terrain flight mode is 25 feet to 80 feet AHO?

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

Answer: (A)

Terrain flight modes control how close you fly to the ground. Contour mode keeps a steady offset above the terrain, typically 25 to 80 feet above the highest obstacle in the flight path. This provides a safe, low-pass altitude over uneven terrain while maintaining a predictable clearance. Nap of the Earth hugs the terrain more closely, staying well under 25 feet, so it wouldn’t match the 25–80 ft range. Level Flight maintains a fixed altitude above the ground and doesn’t adapt to terrain, which wouldn’t satisfy the required clearance. Hover is simply staying in one spot and isn’t a terrain-following mode. So the mode that fits the 25–80 feet above the highest obstacle requirement is Contour.
