How we keep it trustworthy

Safety & accuracy

Aviation knowledge has real consequences. We build for traceability and human oversight — and we are honest about how each item was reviewed.

Source-controlled

Every claim traces to a source

Curriculum lives under version control. Each statement is tied to a citation from authoritative, current FAA material, so claims can be traced, checked, and updated.

Review gate

Instructional review before publication

Nothing safety-critical is published as reliable until it passes an instructional review gate. The private pilot curriculum, practice questions and answer choices were reviewed by a panel of three certificated flight instructors (CFIs), alongside our AI instructional-review system (AI_CFI).

Honest status

Review labels tell the truth

We say exactly what each review covered. The CFI panel reviewed the private pilot curriculum, practice questions and answer choices. The panel reviewed every practice question, including the supplemental bank. The AI instructor’s live chat answers, the instrument (IFR) track and pages added after that review are labeled as AI-reviewed or AI-generated, not CFI-reviewed.

AI is a tool

AI is never authoritative

The AI instructor is retrieval-grounded to approved material and cites sources. It is treated as a study aid — never as an authoritative aviation source — and it refuses operational and medical questions.

How a claim becomes a lesson

  1. Draft against a source. An author writes original content and attaches a citation e.g. 14 CFR / FAA-H-8083 to each substantive claim.
  2. Automated checks. Content-integrity checks flag uncited claims, broken references, and drift from the source of truth.
  3. Instructional review. The AI_CFI review system (two independent AI reviewers, reconciled, with source verification) checks correctness and safety before the content is treated as reliable. The private pilot curriculum, practice questions and answer choices were also reviewed by a panel of three certificated flight instructors (CFIs).
  4. Publish with status. Until that review clears, content stays unpublished. Published content records exactly which review cleared it.
Always verify against official FAA sources. Our curriculum is built from the PHAK, AIM, 14 CFR and the Private Pilot ACS, and every answer cites its source. The CFI panel review covers the private pilot curriculum and all practice questions — not the AI instructor's live chat answers, the instrument (IFR) track, or pages added after that review. Confirm regulations and procedures against current official FAA publications and your instructor. A course-completion certificate is not an FAA pilot certificate. See the FAQ.
