14 CFR Part 135 Air Carrier and Operator Certification Exam

14 CFR Part 135 Air Carrier and Operator Part 135 governs commercial air operations at a scale most pilots never encounter—charter flights, scheduled commuter service, cargo operations. This exam dives into regulatory complexities that don’t apply to Part 91 or Part 121, including crew rest rules, aircraft maintenance directives, and operational limits specific to smaller commercial carriers. Pass it, and you’ve mastered a niche regulatory framework.
