Which two terrain flight modes are explicitly named in the material?

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

Answer: (A)

In terrain flight training, two flight modes are specifically named for how a helicopter interacts with the ground. Nap of the Earth, abbreviated NOE, involves staying extremely close to the terrain’s surface, skimming over it to minimize exposure and match the ground features. Contour mode keeps a steady distance above the terrain as you follow the natural shape of the land, staying level with hills and valleys rather than climbing to a fixed altitude. These two are the terrain-following modes highlighted in the material, whereas Hover and Level Flight are general flight modes and not described as terrain-following.
