- AGI training must cover all 16 domains from 14 CFR 61.125(b), not just aerodynamics topics.
- The FAA test has 100 scored questions, runs 2 hours 30 minutes, and requires 70% to pass.
- No pilot certificate, medical, or flight hours are required - training is purely knowledge-based.
- Test fee is $175 plus tax through PSI; candidates may sit for it starting at age 16.
What Is AGI Training?
AGI training is the process of preparing for the FAA Advanced Ground Instructor knowledge test - the credential that authorizes someone to provide ground instruction and sign knowledge-test recommendations for private, commercial, and instrument-adjacent subjects (excluding instrument-rating subject matter itself, which falls to the Instrument Ground Instructor rating). Unlike flight training, AGI training is entirely knowledge-based. There's no practical test, no logbook of flight hours, and no medical certificate required. What matters is whether you can demonstrate mastery of the same knowledge areas the FAA expects of commercial pilot applicants under 14 CFR 61.125(b), plus supplemental material referenced in 61.97, 61.105, 61.155, and 61.309.
If you're still mapping out what the certificate involves before committing to a training plan, it helps to start with a broader overview like AGI Certification or What Is AGI Certification?, then circle back here once you understand the destination.
Exam Mechanics: Fees, Format, and Timing
Before building a training plan, know exactly what you're training for. The FAA administers the AGI knowledge test through PSI testing centers. Here's what candidates should plan around:
| Exam Detail | Specification |
|---|---|
| Test fee | $175 plus applicable tax |
| Question count | 100 scored multiple-choice questions (plus possible unscored validation items) |
| Time allowed | 2 hours 30 minutes |
| Passing score | 70% |
| Minimum age to test | 16 |
| Minimum age for certificate issuance | 18 |
| Instructor endorsement required for initial attempt | No |
Because no endorsement is required, training is entirely self-directed unless you choose a course or mentor. That makes it your responsibility to verify you've covered every domain - there's no instructor signing off that you're ready. For a deeper dive into what "ready" actually looks like on test day, see How Hard Is the AGI Exam? Complete Difficulty Guide 2026.
Key Takeaway
Since no instructor sign-off is needed, use a structured domain checklist rather than assuming general aviation knowledge is enough - the test draws precisely from the 16 listed content areas.
The 16 AGI Domains You Must Train For
The AGI knowledge test is built entirely from 16 domains that mirror the commercial pilot knowledge areas in 14 CFR 61.125(b), with one addition specific to lighter-than-air ground training. Effective AGI training treats each domain as its own mini-course rather than blending everything into generic "aviation knowledge" review. A full breakdown of each domain's subtopics lives in AGI Exam Domains 2026: Complete Guide to All 16 Content Areas, but here's how to think about training for the highest-density areas.
Domain 1: Applicable Federal Aviation Regulations
Focus on regulations tied to commercial pilot privileges, limitations, and flight operations - not the entire FAR/AIM.
- Commercial pilot privileges and operating limitations
- Currency and recency requirements referenced across Part 61
Domain 2: NTSB Accident Reporting Requirements
A narrow but frequently tested area covering what must be reported and within what timeframe.
- Immediate notification triggers
- Wreckage and records preservation duties
Domains 3, 5, 12, 13: Aerodynamics, Operations, Systems, and Maneuvers
These four domains form the technical backbone of the exam and often overlap in question wording.
- Lift, drag, stability, and load factor relationships
- Aircraft systems function and failure symptoms
- Emergency procedure logic, not just checklist memorization
Domain 4: Meteorology
Emphasizes critical weather recognition - windshear, thunderstorms, icing - plus interpreting METARs, TAFs, and other aeronautical weather products.
- Windshear recognition and avoidance techniques
- Reading and applying aviation weather reports and forecasts
Domains 6, 7, 8: Weight, Performance, and Limitations
These are calculation-heavy domains requiring chart-reading fluency, not memorized numbers.
- Weight and balance computation methods
- Reading performance charts for takeoff, climb, and landing data
- Consequences of exceeding structural and performance limits
Domains 9, 10, 15: Navigation and Airspace
Covers chart interpretation, magnetic compass use, dead reckoning, air navigation facilities, and National Airspace System procedures.
- Sectional chart symbols and pilotage techniques
- VOR and other navigation facility usage
- Airspace classification and operating procedures
Domain 11: Aeronautical Decision Making
Scenario-based judgment questions rather than pure fact recall - expect situational prompts about risk management.
- Recognizing hazardous attitudes
- Applying risk-assessment models to sample scenarios
Domain 14: Night and High-Altitude Operations
Physiological and procedural knowledge specific to reduced visibility and oxygen environments.
- Night vision limitations and illusions
- Hypoxia symptoms and supplemental oxygen requirements
Domain 16: Lighter-Than-Air Ground Training Procedures
The one domain without a direct commercial pilot equivalent - covers ground and flight training procedures specific to balloon and airship ratings.
- Training sequence differences for lighter-than-air ratings
- Ground instruction obligations unique to LTA candidates
Who Actually Needs AGI Training
AGI training isn't just for people chasing a standalone credential - it's frequently pursued alongside other instructor ratings. Common candidates include:
- Flight schools' ground school instructors who don't fly but teach classroom or online knowledge courses
- CFIs who want to sign knowledge-test recommendations for ground-only students
- Career-changers entering aviation education without pursuing a pilot certificate themselves
- Part 141 school staff supporting structured ground curricula
Because no pilot certificate or flight experience is required, AGI training attracts people from outside the cockpit entirely - dispatchers, aviation educators, and aspiring CFIs building credentials in sequence.

A Domain-Based Training Timeline
Generic study techniques - spaced repetition, timed drills, active recall - only matter if they're mapped to the actual domain list. Here's a sample structure that assigns each week to specific AGI content rather than vague "review" blocks.
Regulatory and Reporting Foundations
- Work through Domain 1 (applicable FARs) and Domain 2 (NTSB reporting) together, since both are regulation-recall heavy
- Build a quick-reference sheet of reporting timeframes
Aerodynamics, Systems, and Maneuvers
- Study Domains 3, 12, and 13 together - aerodynamic principles explain why systems fail and why maneuvers are performed as they are
Weather and Performance Math
- Pair Domain 4 (meteorology) with Domains 6-8 (weight, balance, performance charts) since both require chart-reading under time pressure
- Practice timed chart problems to simulate the 2.5-hour exam pace
Navigation, Airspace, and Judgment
- Cover Domains 9, 10, 15 (navigation/airspace) and Domain 11 (ADM) - scenario questions in this block benefit from practice-test repetition
Specialized Topics and Final Review
- Finish Domain 14 (night/high-altitude) and Domain 16 (LTA procedures)
- Take full-length timed practice exams on AGI Exam Prep's practice test platform
This is only a template - some candidates compress it into two weeks, others need eight. What matters is that every domain gets dedicated attention rather than being absorbed into a single undifferentiated "study aviation" phase. For a more detailed week-by-week walkthrough, see AGI Study Guide 2026: How to Pass on Your First Attempt.
Choosing Training Materials
AGI training materials generally fall into three categories: FAA source documents, commercial test-prep courses, and practice question banks. Each serves a different purpose.
- FAA source documents (Pilot's Handbook of Aeronautical Knowledge, Airplane Flying Handbook, Aviation Weather Handbook) - the authoritative content behind every question
- Structured courses - useful for candidates who want a guided sequence through all 16 domains rather than self-organizing
- Practice question banks - essential for gauging readiness against the actual 100-question, 70%-threshold format; run full-length timed sets on AGI Exam Prep to build familiarity with pacing before test day
Whichever combination you use, make sure your materials explicitly reference the 16-domain structure. Generic "commercial pilot knowledge" study guides can miss Domain 16 (lighter-than-air procedures) entirely since it has no direct commercial pilot equivalent - don't let that gap catch you off guard. If you want the essential facts condensed into one reference, bookmark the AGI Cheat Sheet 2026: One-Page Review of Must-Know Facts.
Key Takeaway
Cross-check any training material's table of contents against the 16 official domains before committing time to it - missing Domain 16 or under-covering weight-and-balance math are common gaps.
Staying Current After You Pass
Passing the knowledge test is only step one. Certificate issuance also requires being at least 18, demonstrating English proficiency, and passing the Fundamentals of Instructing test (unless an exemption applies). None of this requires a pilot certificate, medical certificate, flight experience, or a practical test - AGI remains a purely knowledge-based credential from application through issuance.
Once issued, the certificate itself doesn't expire - but exercising its privileges does have a maintenance requirement. Within any preceding 12 calendar months, you need one of the following:
- Qualifying instructional activity
- An approved refresher course
- A proficiency endorsement
This distinction - permanent certificate, lapsing privileges - surprises a lot of new AGIs. Build a reminder into your calendar well before the 12-month mark so you're never caught unable to legally exercise privileges you worked to earn. For eligibility nuances before you even sit the exam, review AGI Requirements 2026: Eligibility, Prerequisites & How to Qualify.
