It is all entirely circumstantial. There are instances where arrests for minor infractions and charges never make it into the FBI database. What you are required to disclose on a job application largely depends on the legal outcome and the wording of the application. Airlines cannot ask about arrests but an arrest may leave a paper trail in another database such as the NDR. The OP should really consult an attorney familiar with aviation employment matters.
