Pilot/Controller Glossary (PCG)
The Pilot/Controller Glossary (PCG) is a free FAA reference that defines aviation terms used in the air traffic control system. Published as an appendix to the AIM, it provides standardized definitions for phraseology used in pilot-controller communications. It is the authoritative source for ATC terminology and is referenced on FAA knowledge tests.
Why This Document Matters
The Pilot/Controller Glossary is the aviation dictionary you did not know you needed until you failed a question on the knowledge test because you confused 'NOTAM' types or could not define 'LAHSO.' It defines every term used in pilot-controller communications, from 'acknowledge' to 'zulu time.' The PCG is published as part of the Aeronautical Information Manual but is often referenced separately. For radio communication training, knowing these definitions helps you understand exactly what ATC is asking you to do. The glossary is organized alphabetically and includes cross-references to related terms.

Study Tips
- Do not try to memorize the entire glossary. Focus on terms that appear in knowledge test questions: LAHSO, SVFR, EFC, NOTAM types, and clearance terminology.
- Use the PCG as a reference tool during ground school — when your instructor uses a term you don't recognize, look it up immediately.
- Pay special attention to the distinction between ATC instructions and ATC clearances — they have different legal implications for the pilot.
- Cross-reference PCG definitions with AIM Chapter 4 (Air Traffic Control) to see the terms used in context.
- For radio communication practice, study the phraseology examples — the PCG defines not just what terms mean but how they should be used.
Frequently Asked Questions
Is the Pilot/Controller Glossary the same as the AIM?
No. The PCG is published as an appendix to the AIM but is a standalone reference. The AIM explains procedures and regulations, while the PCG defines the specific terminology used in those procedures.
Are PCG definitions tested on the FAA knowledge test?
Yes. Several knowledge test questions test your understanding of ATC terminology. Definitions like 'clearance,' 'instruction,' 'LAHSO,' and various NOTAM types appear frequently on the Private and Instrument knowledge tests.
How often is the Pilot/Controller Glossary updated?
The PCG is updated whenever the AIM is revised, which happens multiple times per year. Always reference the most current version online rather than a printed copy.
