Example Embodiment
[0140] Example
[0141] Model A319, under the condition of maximum take-off weight, overruns the runway at a speed of 70kt. In the rear section, the main landing gear has brakes with a coefficient of friction of 0.25. Inside the arresting bed, without brakes. Ignore the aerodynamics of the aircraft during arrest. The initial arresting system follows figure 2 design.
