FAR 61.165 — Additional ATP Ratings
FAR 61.165 explains how an existing ATP holder adds another aircraft category or class rating, including knowledge, experience, and practical test requirements.
In Plain English
FAR 61.165 sets the requirements for an Airline Transport Pilot (ATP) who already holds an ATP certificate and wants to add another aircraft category or class rating (rotorcraft/helicopter, airplane single- or multi-engine, or powered-lift).
For each added rating, the applicant generally must:
- Meet the eligibility requirements of § 61.153
- Pass a knowledge test on the aeronautical knowledge areas of § 61.155(c)
- Comply with § 61.157(b) training/experience requirements, if applicable
- Meet the aeronautical experience requirements of the appropriate section (§ 61.159 for airplanes, § 61.161 for rotorcraft, § 61.163 for powered-lift)
- Pass the practical test on the areas of operation in § 61.157(e) for that category/class
Adding a multiengine airplane rating also requires completing the ATP Certification Training Program (ATP-CTP) under § 61.156. When adding only a class within the same category already held, no new knowledge test is required (per paragraph (e)). This rule matters because it lets working ATPs expand into new aircraft without repeating the entire ATP process.

Oral Exam Questions a DPE Might Ask
Q1You already hold an ATP in airplanes. What must you do to add a helicopter class rating to your ATP?
Per FAR 61.165(a), you must meet § 61.153 eligibility, pass the § 61.155(c) knowledge test, comply with § 61.157(b) if applicable, meet the rotorcraft experience requirements of § 61.161, and pass the practical test on the areas of operation in § 61.157(e)(4).
Q2If you hold an ATP single-engine airplane and want to add a multiengine class rating, is the ATP-CTP required?
Yes. FAR 61.165(c) requires successful completion of the ATP Certification Training Program in § 61.156, plus a knowledge test, the experience of § 61.159 or § 61.160, and the practical test on § 61.157(e)(2) areas of operation.
Q3When adding a class rating within the same aircraft category as your existing ATP, do you have to take another knowledge test?
No. Under FAR 61.165(e), an applicant adding a class rating within the same category they already hold at the ATP level is not required to take an additional knowledge test, but must still meet § 61.153 eligibility (except (g)), § 61.157(b) if applicable, the experience requirements of subpart G, and the appropriate § 61.157(e) practical test.
