What is another word for terrain flight?
Pronunciation: [təɹˈe͡ɪn flˈa͡ɪt] (IPA) 
Terrain flight can be defined as an aircraft flying close to or touching the ground, sometimes to avoid radar detection or to maneuver in mountainous terrain. Some synonyms for terrain flight include low-level flight, nap-of-the-earth flying, hedge-hopping, treetop-level flying, and canyon carving. These terms all describe flying techniques that require the pilot to fly at very low altitudes, often using land features to navigate. Low-level flight refers to flying close to the ground, while nap-of-the-earth is a military term for flying as low as possible to avoid enemy fire. Hedge-hopping and treetop-level flying both refer to the practice of flying between trees or around obstacles at low altitudes. Finally, canyon carving describes flying through canyons and valleys at low altitudes.
