Two of the Fa-223s were used in maneuvers at the mountain Warfare school in the Alps near Innsbruck during September 1944. Ships V14 and V16 were utilized to supply the mountain troops. The aircraft flew 83 missions, flying on 29 of the 30 days. The one day of non operation was due to fog so thick the pilot could not see the tips of the rotors. Seventeen landings were made on sites that were 4500 feet or more above sea level, including three on the Dresdener Hutte, at an elevation of 7600 feet.
The extensive maneuvers demonstrated the helicopter had a place in mountain warfare. The Fa-223 could lift 1100 pounds of provisions to a remote site at an elevation of 6500 feet in just seven minutes, a feat that would require twenty men, a day and half of strenuous climbing, to accomplish. in one fifteen minute round trip flight from the base at Mittenwald, a mountain howitzer and its ammunition were lifted on a cable below the helicopter, then flown to, and safely lowered to a position just below the Wornergrat peak. The gun had to be winch lowered, because there was not enough room to land.
The Fa-223 was used as a troop transport during maneuvers and carried as many as 12 troops in addition to the pilot. Four men were carried inside the cabin and eight were carried on tractor seats fastened to the outriggers.
When the mountain maneuvers ended on October 5,1944, the head of the Mountain Warfare School enthusiastically endorsed the Fa-223 and everyone expected that there would be a push for production of the Drache. instead, on October 11th, an order was received from the Air ministry to stop all work on the Fa-223 and transfer all Focke Achgelis personnel to Messerschmitt. The Me-262 jet fighter required all the skilled labor available for production and as the Allies closed in on Germany from east and west, factories were being set up in remote areas, away from the bombing devastating German industrial plants.
