![]() ![]() ![]() The lowest NOE flying is by helicopters because they have lower speeds and more maneuverability than fixed-wing aircraft, particularly fast-jets. Helicopter NOE flying Helicopter following a river to enable low level flight AH-64 Apache at the Oirschotse Heide Low Flying Area At night, a night-vision device may be used. Data from a radar altimeter or terrain-following radar system is also used, the latter enabling low flying in adverse weather where it would not be possible by visual reference and manual pilot control. Most NOE flying is done during the day using visual reference by pilots who are experienced in low flying. ![]() Doppler radar has the potential to detect NOE flight, but the incoming aircraft has to be within radar range in the first place, and low flight minimizes this possibility by using hills and mountains to break the line of sight (terrain masking), defeating terrestrial air defense radar and in rough enough terrain also airborne early warning. Using NOE flight, the approach may be undetected the aircraft "pops up" to attack the target and then turns to escape before the enemy can respond. Ī high-flying aircraft can be detected by defense systems at long range, giving an air defense system time to react, alerting surface-to-air missile and anti-aircraft systems and fighter aircraft. ![]() NOE is used to minimize detection by hostile aircraft, airborne early warning and control surveillance and control systems, ground-based radar, or attack targets. This keeps the aircraft below enemy air defence radar coverage, avoiding being silhouetted against the sky. Other, mostly older terms include "contour flying", "ground-hugging", "terrain masking", "flying under the radar" and "hedgehopping".ĭuring NOE flight, geographical features are used as cover, exploiting valleys and folds in the terrain by flying in, rather than over, them. Nap-of-the-earth ( NOE) is a type of very low-altitude flight course used by military aircraft to avoid enemy detection and attack in a high-threat environment.
