Block 6 of the Aircraft Inspection Record is used to track what information?

Block 6 of the Aircraft Inspection Record is specifically used to track oil levels. This information is critical for ensuring that the aircraft's engines and other mechanical components function correctly. Regular monitoring of oil levels helps in assessing the overall health of the aircraft's systems, as oil is essential for lubrication, cooling, and preventing wear and tear on engine parts. Maintaining appropriate oil levels is vital for operational safety and efficiency.

While other information such as oxygen levels, fuel load, and flight hours are also important for various aspects of aircraft operations, they are tracked separately within different sections of documentation or through specific operational logs and records. This focused tracking of oil levels in Block 6 underscores its importance in maintenance protocols and safety checks for aircraft.
