A test program was conducted to determine the performance capability of the 44B-2C emergency arresting gear configured on a 50-meter 164-foot deck span during arrestments of the F-5, A-4, F-102, F-105, and F-4J aircraft at aborted takeoff weight conditions. The weight classes of these aircraft were simulated by use of a 21,000- and 24,500-pound F-8 aircraft, a 33,000-pound F-4A aircraft, and a 48,000-pound A-3 aircraft. Arrestments of the F-8 and F-4A were conducted ON-CENTER and 30 feet OFF-CENTER over an engaging-speed range of approximately 100 to 160 knots, and arrestments of the A-3 were conducted ON-CENTER at speeds ranging from 52 to 118 knots. Based on the test results, the F-5, F-102, and F-105 aircraft are limited by arresting-hook load the F-4J aircraft is limited by arresting-gear capacity and the A-4 aircraft is not subject to a limit up to the test-program speed of 160 knots. Purchase-tape and deck-pendant tension limits were not exceeded. In general, higher aircraft arresting-hook loads and higher purchase-tape tensions in the short-side tape occurred during the OFF-CENTER arrestments. Aircraft runout characteristics were satisfactory. No arresting-hookbumper contact damage occurred, and the aircraft structures showed no evidence of deck-pendant contacts. Arrestments of aircraft weighing more than 48,000 pounds are not recommended. Author
