Abstract : The patent relates to a self-locking holdback cleat to restrain an aircraft during high power engine run-ups. The cleat has two pieces--a shoe, attached to the aircraft via a draig-chain, and a deck plate. The shoe has a spool-type button mounted thereon, which drags along the ground as the aircraft moves into position and engages the fixedly mounted deck plate. The deck plate has ramped under-cutting forming a vertical labyrinth which guides the button into locking engagement. When tension is released from the chain, the button may be manually released from the deck plate.
