Pagination or Media Count:
Engineering flight tests were conducted by the United States Army Aviation Systems Test Activity to determine if any adverse autorotational entry or landing characteristics would preclude increasing the maximum operational gross weight of the AH-1G helicopter above the current 9500 pounds. A production AH-1G helicopter with tractor tail rotor was flown 14.4 hours at Edwards Air Force Base, California between 26 September and 12 October 1973 in the Hog configuration. Autorotational entries were performed successfully at gross weights from 9000 to 10,000 pounds from climbs, level flight, and dives. Modified author abstract
