What does the acronym "BIT" refer to in the F/A-18 E/F?

The acronym "BIT" in the context of the F/A-18 E/F refers to "Built-In Test." This feature is critical in the aircraft as it comprises self-diagnostic capabilities that help identify and troubleshoot any malfunctions within various systems onboard. Built-In Tests run automatically during pre-flight checks and regularly throughout flight operations to ensure that all critical avionic systems are operational and functioning correctly.

These tests enhance maintenance efficiency, allowing crew members to quickly determine the status of the aircraft's systems and make informed maintenance decisions. Additionally, identifying potential issues early through BIT helps ensure flight safety by addressing problems before they can affect performance or mission capability.
