Where can you find leveling instructions for an aircraft?

The correct location to find leveling instructions for an aircraft is in the Type Certificate Data Sheets (TCDS). The TCDS contains critical information about the aircraft, including its specifications, limitations, and operational requirements, which can encompass weight and balance parameters. Leveling instructions are essential for ensuring accurate weight and balance calculations during pre-flight checks, and they often prescribe specific reference points for leveling the aircraft.

While the pilot's operating handbook does contain useful operational information, it typically focuses on handling procedures and emergency protocols rather than detailed specifications like leveling instructions. Likewise, while the maintenance manual provides comprehensive service and maintenance guidelines, it may not specifically outline leveling instructions, as these are typically standardized and included in the TCDS. Finding leveling instructions on the aircraft's exterior is not practical, as such information is not physically marked on the aircraft itself. Therefore, the TCDS is the most authoritative source for this critical information.
