# Advanced Certificates Part of the Aviation Merit Badge Digital Resource Guide: [Introduction & Overview](https://merit-badge.university/merit-badges/aviation/guide/index.md) *5. Aviation Careers* > **5c.** Explain the following: the commercial pilot certificate, the airline transport pilot certificate, and certified flight instructor (CFI). These three certificates represent the upper tiers of pilot certification. Each one opens new doors — from getting paid to fly, to commanding an airliner, to teaching the next generation of pilots. ### Commercial Pilot Certificate The **commercial pilot certificate** is the first certificate that allows a pilot to fly for money. A private pilot can share expenses with passengers, but a commercial pilot can actually be *hired* to fly. **Key facts:** - **Minimum age:** 18 years old - **Flight time required:** 250 hours minimum (including time in specific categories like cross-country, night, and instrument flight) - **Prerequisites:** Private pilot certificate and instrument rating - **Exams:** Written knowledge test and a practical test (check ride) with higher performance standards than the private pilot check ride - **Medical certificate:** Requires at least a Second Class medical certificate (more rigorous than the Third Class required for private pilots) **What a commercial pilot can do:** - Fly charter flights - Tow banners and gliders - Conduct aerial photography and surveying - Fly air tours - Serve as a copilot for a regional airline (with the right type ratings) - Fly cargo **What a commercial pilot cannot do (yet):** - Serve as pilot-in-command (captain) of a scheduled airline flight — that requires the ATP certificate > **Tip** > > Many commercial pilots build flight hours by working jobs like banner towing, aerial surveying, or flying skydivers. These jobs may not be glamorous, but they provide valuable real-world experience and help pilots reach the hours needed for an airline career. ### Airline Transport Pilot Certificate (ATP) The **airline transport pilot certificate** is the highest level of pilot certification. If the commercial certificate is a driver's license, the ATP is a CDL for the sky. An ATP is required to serve as the captain (pilot-in-command) of a scheduled airline. **Key facts:** - **Minimum age:** 23 years old (21 for restricted ATP under certain military or collegiate programs) - **Flight time required:** 1,500 hours minimum (1,000 for military pilots; 1,250 for graduates of approved aviation degree programs) - **Prerequisites:** Commercial pilot certificate with instrument rating - **Exams:** ATP written knowledge test and a rigorous practical test - **Medical certificate:** First Class medical certificate (the most stringent — includes EKG screening for pilots over 40) **What an ATP pilot can do:** - Serve as captain of any scheduled airline flight - Fly for major airlines (Delta, United, American, Southwest, etc.) - Command international flights carrying hundreds of passengers > **Did You Know?** > > The 1,500-hour rule for ATP certification was established in 2013 after the Colgan Air Flight 3407 crash near Buffalo, New York, in 2009. Before that rule change, first officers at regional airlines could fly with as few as 250 hours. The rule significantly increased the experience level of airline pilots. ### Certified Flight Instructor (CFI) A **Certified Flight Instructor** is a pilot who is authorized to teach others to fly. The CFI certificate is not higher than the commercial or ATP — it is a separate authorization that allows a pilot to provide flight instruction and sign off student pilots for solo flights, check rides, and endorsements. **Key facts:** - **Minimum age:** 18 years old - **Prerequisites:** Commercial pilot certificate (or ATP); instrument rating is required for CFII (Certified Flight Instructor — Instrument) - **Exams:** Written knowledge test on the fundamentals of instruction (FOI) and a practical test where the applicant demonstrates the ability to teach - **What makes the CFI unique:** The practical test is not just about flying well — it is about *explaining* what you are doing and *teaching* the examiner as if they were a student **Why become a CFI?** - **Build hours:** Most aspiring airline pilots become CFIs to accumulate the flight hours needed for an ATP certificate. Teaching is one of the best ways to log hours while getting paid. - **Give back:** Many pilots become instructors because they love sharing their passion for flight. The CFI who taught you is the reason you know how to fly. - **Stay sharp:** Teaching forces you to understand aviation concepts deeply. If you can explain a stall recovery to a nervous student, you truly understand it. ### The Certification Ladder Here is how the certificates typically build on each other: 1. **Student Pilot** → Learn to fly, solo 2. **Private Pilot** + **Instrument Rating** → Fly for personal use in most conditions 3. **Commercial Pilot** → Fly for pay 4. **CFI** → Teach others and build hours 5. **ATP** → Captain an airliner ![A visual ladder or staircase showing the progression from Student Pilot at the bottom to ATP at the top, with each certificate level labeled and the minimum age and hours shown](https://ik.imagekit.io/doulacoop/tr:w-800/mbu-assets/merit-badges/aviation/guide/pilot-career-ladder?v=d1768b99) [FAA — Airline Transport Pilot Certificate](https://www.faa.gov/pilots/become/atp): FAA guide to the ATP certificate, including eligibility requirements and the restricted ATP option for military and collegiate pilots. --- - Previous: [Instrument Rating](https://merit-badge.university/merit-badges/aviation/guide/req5b/index.md) - Next: [Aviation Organizations](https://merit-badge.university/merit-badges/aviation/guide/req5d/index.md)
