Is it permissible for aircrew members to use any FLIP product, regardless of date and completeness?

The correct answer is that aircrew members must only use current FLIP (Flight Information Publication) products. The primary reason for this requirement is to ensure that pilots and other aircrew members have the most accurate, up-to-date, and complete information necessary for safe flight operations. Flight procedures, navigational aids, and other critical operational information may change frequently due to factors such as regulatory updates, airspace modifications, and safety improvements. Using outdated or incomplete publications could lead to misunderstandings and mistakes, potentially compromising safety.

Aircrew members are required to stay current, which underscores the importance of relying on the latest available materials. Depending on outdated information can pose risks, including the potential for conflicting procedures or incorrect airspace designations. Therefore, adherence to using only current FLIP products is a core component of maintaining operational safety and compliance with regulations.

It is important to note that familiarity with procedures or legibility does not compensate for the need to work with current materials, as outdated publications are not reliable sources for safe flight operations.
