FAR 61.185 — CFI Aeronautical Knowledge
FAR 61.185 sets the ground training topics required for a flight instructor certificate, including fundamentals of instructing and pilot knowledge areas.
In Plain English
FAR 61.185 lists the ground training topics you must receive and log from an authorized instructor before you can earn a flight instructor (CFI) certificate. The rule has two parts: what you must learn, and who gets a pass on the teaching-theory portion.
Applicants must receive ground training on:
- Fundamentals of Instructing (FOI) — the learning process, elements of effective teaching, student evaluation and testing, course development, lesson planning, and classroom training techniques.
- The aeronautical knowledge areas for the recreational, private, and commercial certificates in the aircraft category you want to instruct in.
- The instrument rating knowledge areas for the category, if you're seeking CFII privileges.
The FOI portion can be skipped if you already hold a flight or ground instructor certificate, hold a state-issued teacher's certificate valid for 7th grade or higher, or are employed as a teacher at an accredited college or university.
This matters because a CFI is expected to teach every knowledge area a student pilot will be tested on — so you must master that material at a deeper, instructional level before signing off others.
Regulation Text

Oral Exam Questions a DPE Might Ask
Q1What aeronautical knowledge training does an applicant for a flight instructor certificate need?
Per FAR 61.185, the applicant must receive and log ground training from an authorized instructor on the fundamentals of instructing, plus the aeronautical knowledge areas for the recreational, private, and commercial pilot certificates in the category sought — and instrument rating knowledge areas if pursuing CFII privileges.
Q2What are the fundamentals of instructing you had to study for your CFI?
FAR 61.185(a)(1) requires training on the learning process, elements of effective teaching, student evaluation and testing, course development, lesson planning, and classroom training techniques.
Q3Who is exempt from the fundamentals of instructing requirement?
Under FAR 61.185(b), the FOI requirement is waived for holders of a flight or ground instructor certificate, holders of a state/county/city teacher's certificate valid for 7th grade or higher, or persons employed as a teacher at an accredited college or university.

Source checked: 14 CFR § 61.185; date_retrieved: 2026-05-29.
§61.185 is easy to misread as a single written-test rule. It is really a ground-training audit: confirm whether the fundamentals of instructing apply, then match the aeronautical knowledge areas to the exact instructor privilege sought.
| Applicant track | Ground-training bucket | Knowledge-test target |
|---|---|---|
Initial CFI airplane The FOI training exemption in §61.185(b) is not the same as skipping the category knowledge requirement. | FOI + category knowledge | FOI plus the applicable flight-instructor airplane knowledge test |
Additional CFI rating Already holding a CFI certificate can remove FOI ground training, but the new rating still needs the applicable knowledge areas. | Category-specific knowledge | Knowledge areas appropriate to the additional instructor rating sought |
Instrument instructor §61.185(a)(3) adds instrument-rating knowledge areas when instrument instructor privileges are sought. | Instrument rating knowledge for the category | Instrument flight instructor knowledge test appropriate to the category |
FOI topics in §61.185(a)(1)
- Learning process
- Elements of effective teaching
- Student evaluation and testing
- Course development
- Lesson planning
- Classroom training techniques
FOI training exemptions in §61.185(b)
- Flight instructor certificate holder
- Ground instructor certificate holder
- Current teacher certificate for grade 7 or higher
- Accredited college or university teacher

§61.185 questions students ask
Q1What does 14 CFR §61.185 require for a flight instructor applicant?
It requires logged ground training from an authorized instructor on fundamentals of instructing unless an exemption applies, plus aeronautical knowledge areas for the pilot certificate level and category tied to the instructor privileges sought.
Q2Does §61.185 require FOI training for every CFI applicant?
No. §61.185(b) exempts current flight instructors, ground instructors, qualifying grade-7-or-higher teachers, and accredited college or university teachers from the FOI ground-training requirement in §61.185(a)(1).
Q3How does FAR 61.185 apply to a CFII applicant?
When instrument instructor privileges are sought, §61.185(a)(3) adds the instrument rating knowledge areas applicable to the aircraft category. That is separate from the general CFI category knowledge in §61.185(a)(2).
