Abstract

A landing load monitor is used for aircraft during a carrier-type landing event having an arresting cable. The aircraft is provided with a tail-hook assembly that includes a tail-hook and a mounting assembly. The tail-hook is coupled to the aircraft by way of the mounting assembly. A sensor measures the load applied by the tail-hook to the aircraft. A processor is connected to the sensor. The tail-hook loads during a landing event over elapsed time are stored in memory for subsequent retrieval and analysis. The sensor may be located on the tail-hook itself or in the mounting assembly. The aircraft is also provided with inboard and outboard accelerometers on each wing. In addition, the landing gear has pressure sensors to monitor the internal pressure of the landing gear struts. These additional sensors are used during the landing event to monitor the loads on the aircraft. They are also used to identify asymmetrical landings.
