Source methodology
We show our work.
Regulatory claims start with current eCFR and official FAA publications. Every mapped product carries a version, review date, and next-review target.
Research hierarchy
- Current eCFR / 14 CFR
- Federal Aviation Administration
- Current Advisory Circulars and ACS
- FAA handbooks, AIM, and official programs
- Federal Register and NTSB when history or safety data matters
What “source-checked” means
It means a product claim has been compared with an identified current source on the printed review date. It does not mean the FAA approved, certified, or endorsed the product. Guidance and regulations can change after review.
Regulatory products are scheduled for review about every six months and when a mapped source change is detected.
