How is statistical data recorded during maintenance actions?

The correct answer indicates that statistical data during maintenance actions is recorded using VIDS/MAF documents. This choice is accurate as VIDS (Vehicle Identification and Display System) and MAF (Maintenance Action Form) are specifically designed to track maintenance activities. They provide a systematic way of recording detailed data about each maintenance action, including the type of work performed, hours spent, parts used, and any discrepancies noted.

Using VIDS/MAF documents ensures that all relevant maintenance data is available for analysis and future reference, which is crucial for maintaining equipment reliability and safety. The structured format of these documents facilitates consistent reporting and helps in compiling performance metrics, thereby enhancing the overall maintenance management process.

The other options do not fulfill the requirements as effectively. For instance, flight data calculations might relate to performance assessments but would not specifically capture maintenance actions. Manual entries alone can introduce inconsistencies and are not as reliable for systematic data collection. OPNAV forms, while potentially useful in various contexts, do not serve the same specialized purpose as VIDS/MAF documents, which are specifically tailored for maintenance tracking.
