Where can the normal hydraulic levels be found?

The normal hydraulic levels can be found in the ODH (Operational Data Handbook) on page 15-1. This resource provides detailed information about the hydraulic systems and their operational parameters, including the normal levels necessary for safe and effective aircraft operation. The ODH is specifically designed to consolidate operational data in a user-friendly format, making it a reliable source for quick reference during pre-flight checks, in-flight assessments, or maintenance activities.

Other resources, while they may contain valuable operational information related to hydraulic systems, do not specifically designate normal hydraulic levels as clearly as the ODH does on the specified page. Therefore, for precise and accurate data regarding normal hydraulic levels, the ODH is the most appropriate choice.
