RULES AND REGULATIONS
The rules of charter, in plain English
The FAA, DOT and TSA rules that decide who can sell a charter, who can fly it, and what travelers are owed. Each one links to the official text.
What applies to you
Operators
- Carry paying passengers only on aircraft listed in your operations specifications.
- Keep pilots inside Part 135 duty and rest limits, and keep drug and alcohol testing current.
- Keep your DOT registration and insurance filings current.
- Broker another operator's aircraft? Part 295 broker rules apply to that trip too.
