Category II A-7D Arresting Systems Compatibility Tests
Abstract
Seventy successful arrestments of A-7D, S/N 67-14583, were made on two operational Air Force aircraft arresting systems, the standard BAK-12 and the BAK-13. As a result of six approach end engagement procedures were recommended. Runway centerline engagements were made at aircraft weights up to 42,000 pounds. The maximum engagement speed was 167 knots at an aircraft weight of 33,000 pounds. Off-center engagements were also made up to 50 feet from the runway centerline using a 190-foot span between the runway edge sheaves of the arresting systems. Aircraft control problems were not serious except for 50-foot off-center engagements with the BAK-13. Test data indicated that the design limit hookload would only be approached at engagement speeds in excess of 190 knots for both arresting systems. Four tests resulted in missed engagements due to a combination of poor hook shoe attitude and poor cable dynamics. A change in hook shoe design was recommended. The cable dynamics problem occurred with the rail type arresting cable supports when the A-7D main gear passed between the rails. Except for the aircraft hook shoe design, the A-7D proved compatible with each aircraft arresting system using donut type cable supports. There were no failures of the standard BAK-12 or the BAK-13 arresting systems.
