What are the three terrain flight modes?

The three terrain flight modes are Low level, Contour, and NAP of the earth.

These modes are crucial for flight safety and tactical operations. Low level flight is typically at altitudes below 500 feet, allowing aircraft to avoid detection and navigate using terrain features. Contour flight closely follows the natural contours of the terrain to minimize exposure to enemy observation and fire, while maintaining a safe altitude above obstacles. NAP of the earth flight is even lower, where the aircraft flies just above the terrain, often only a few feet off the ground, to conceal its movement from radar and visual detection.

This classification enhances operational effectiveness by promoting stealth and safety in various combat scenarios, allowing pilots to maximize cover from terrain while achieving their mission objectives. Other options do not accurately reflect the recognized modes used in tactical aviation settings.
