What distinguishes contour flight from low-level flight?

Contour flight is characterized by the technique of following the natural contours of the terrain at varying altitudes to maintain a safe clearance above ground while navigating through obstacles. This method allows an aircraft to adapt its flight path to the shape of the land, which is particularly important in mountainous or uneven areas, enabling the pilot to fly at a height that optimizes safety and efficiency.

In contrast, low-level flight typically refers to flying at a consistent low altitude but does not necessarily involve adapting to the terrain in the same manner. Low-level flight can occur at a constant altitude, regardless of terrain features, thereby emphasizing speed and efficiency over terrain-following techniques that contour flight employs. This distinguishes the two as contour flight incorporates variability in altitude to conform to the ground's profile, enhancing both tactical maneuverability and obstacle avoidance.
