Which maneuver could be risky in the context of wire avoidance?

Low altitude flight is considered risky in the context of wire avoidance because it significantly decreases the pilot's ability to detect and react to obstacles such as power lines. At lower altitudes, the helicopter has less time and distance to maneuver in response to unseen wires, especially in areas where visibility is obstructed by terrain or foliage. Additionally, the rotor wash and airspeed at low altitudes can make it difficult to maintain control while navigating around such hazards. Consequently, flying at low altitude requires heightened alertness and meticulous planning to ensure safe navigation in the presence of potential wire hazards.
