Helicopters in forward flight produce hazardous vortices similar to wingtip vortices. These vortices are a result of the lift generated by the rotor blades, and they can be particularly hazardous during hover or low-speed maneuvers, as they can linger longer than those generated by fixed-wing aircraft.

Helicopter rotor blades operate under unique aerodynamic principles that lead to the creation of vortices which have intense, swirling air patterns. Similar to wingtip vortices created by airplanes, the rotor blades can generate significant turbulence behind the helicopter, particularly when flying in proximity to another aircraft or during takeoffs and landings. This turbulence can pose a danger to smaller aircraft or those following in the wake.

Moreover, the intensity of these rotor vortices can vary based on several factors, including the weight of the helicopter and the speed at which it is flying. Unlike some other options that suggest these vortices are either weak or less intense than those of fixed-wing aircraft, the reality is that they can be quite powerful and must be taken into consideration by pilots operating in the vicinity of helicopters.
