Runway Safety NextGen
Operators should achieve a low as reasonably practicable level of runway safety. That is achieved when further mitigations are either impracticable or grossly outweighed by the cost. This requires a prediction of future costs related to accidents or incidents at or near a runway and thus an estimation of the likelihood and the associated costs of occurrences. As a consequence allows that evaluating of the most cost-beneficial mitigations. If the mitigation costs grossly outweigh the likely future accident costs, than the risk is acceptable.
