  • Patent number: 6231007
    Abstract: A method for the exact setting down or taking up of cargo from aircraft is disclosed. When setting down persons or cargo from aircraft which has not landed, the problem arises of an exact setting down not being possible, or only with great difficulty, in particular under adverse weather conditions. The invention provides a method whereby exact and even “spot-on” setting down or taking up of a load is made possible, even if the ambient conditions do not allow the aircraft to be kept steady. With the spatial framework of ropes biased by the aircraft, the position of the load in space is clearly fixed. The load can thus be exactly lowered down to the ground or taken up from the ground, without it being necessary for the aircraft to be still. Here, the aircraft itself is located at an appropriately selected distance above the load. The invention can also be applied to transportation by airships to construction sites, to catastrophe regions, etc.
