Abstract
A rotary aircraft which carries a hanging sling load on at least one support cable, benefits from a stabilizer which generates control signals R to be applied or modulated onto the flight control of the aircraft. At least one sling load pendulum motion detecting unit provides the stabilizer with data on the pendulum motion of the sling load. Additionally, the stabilizer is set up with a working range determination unit Sfor determining the space where free movement is possible in which the rotary aircraft with sling load can move without collision. The stabilizer generates control signals R in dependency of the determined pendulum motion of the sling load and the determined working range.
