First Claim

1. A method for purposes of determining at least one incidence of loading of an aircraft structure comprising the steps:
- optically registering at least one section of the aircraft structure for purposes of determining an “
actual”
optical state of the aircraft structural section,comparing the “
actual”
optical state with a stored “
design”
optical state of the aircraft structural section,recording noises relating to at least one section of the aircraft structure for purposes of compiling an “
actual”
acoustic image of the aircraft structural section,comparing the “
actual”
acoustic image with a stored “
design”
acoustical image of the aircraft structural section,assessing based on structural mechanics whether an overload of at least one part of the aircraft section has occurred, andusing an alien acoustic signal that has been determined as a starting point for the assessing step, whereinoptical markings are provided on a side of the fuselage near the cockpit and near the tail unit, and the markings on each side of the fuselage together define an imaginary straight line extending in a longitudinal direction of the aircraft.

Abstract
A method and an arrangement to determine an incidence of loading of an aircraft structure. A true reality of at least one aircraft structural section is superposed with the virtual reality of the aircraft structural section, and any deviation is established by means of a comparison of the two realities; this deviation is evaluated with reference to its consequences in terms of the structural mechanics involved.
