Publication policy
Section titled “Publication policy”Ordinary aviation factual content requires direct FAA support. Rules of thumb may instead be directly supported by applicable authoritative manufacturer documentation, recognized technical standards, or established aeronautical research. Externally sourced guidance must not imply FAA endorsement.
Published entries must identify the supporting document, edition, and precise location, with explicit assumptions, units, applicability, and limitations. Unsupported or unresolved material remains unpublished. David retains aviation editorial authority; automated checks cannot replace his review.
