Adaptive, not linear

Mastery over minutes watched

A Bayesian mastery model tracks what you actually know per objective, decays it over time, and schedules review — so completion means readiness.

Grounded AI instructor

Cited answers, safe refusals

The AI tutor answers only from approved study material with citations. It refuses real-time operational and medical questions instead of guessing.

Honest by design

Source-controlled curriculum

Every claim traces to a source. Nothing safety-critical publishes without human CFI review. Certificates are cryptographically verifiable.

Phase 1 preview. This build ships the Airspace and Operating Requirements module as a working vertical slice: lessons, a diagnostic, 13 practice questions, adaptive mastery, and the grounded AI instructor. Content is draft pending certified-flight-instructor review and is not yet an authoritative source.

The Airspace System at a Glance

Controlled airspace is Classes A–E; uncontrolled airspace is Class G. VFR private pilots mostly operate in E and G and transit B/C/D near busy airports.

Busy Airports: Class B, C and D

D = be heard; C = be heard and seen (transponder + ADS-B); B = be heard, seen, and explicitly cleared.

VFR Weather Minimums

Class B: 3 SM, clear of clouds. Class C/D/E <10,000: 3 SM + 500/1,000/2,000. Class G day low: 1 SM, clear of clouds. Special VFR (by ATC clearance) allows clear-of-clouds and 1 SM in a controlled surface area; at night it requires an instrument-rated pilot and instrument-equipped aircraft.
