In the context of aircraft maintenance, what does "ISO" represent?

In the context of aircraft maintenance, "ISO" stands for Integrated Maintenance System. This term refers to a standardized approach that incorporates various aspects of maintenance processes, ensuring efficiency, safety, and compliance with applicable regulations within the aviation industry. An Integrated Maintenance System streamlines operations by coordinating maintenance activities, tracking the status of aircraft, and utilizing data-driven insights to improve overall maintenance practices. This harmonization is critical to optimizing aircraft readiness and reliability, ultimately enhancing safety and operational efficiency.

The other options, while they may sound plausible, do not align with standard aviation terminology or practices related to maintenance processes. For instance, International Safety Operations and Integrated Safety Organization suggest a broader focus on safety rather than the specific context of maintenance systems. Initial System Operations, meanwhile, refers more to a phase of aircraft readiness rather than an overarching maintenance strategy.
