Definition
A reference section located at the end of the Aviation Instructor's Handbook containing supplementary material that supports the main chapters. In the context of Chapter 9, Appendix A is cited as the location where readers can find additional practical test information referenced in the chapter text.
Plain English
An extra section at the back of the book that holds supporting information the main chapters point to. When the chapter says 'see Appendix A,' it means turn to that section at the back for more detail.
Context Anchor
Seen when an FAA handbook or training document points the reader to supporting material outside the main chapter.
Derivation
From the Latin appendere, meaning 'to hang upon.' An appendix is something attached or hung onto the main work — extra material that supports the main text without being part of its main flow.
Why Pilots Care
When a handbook points to Appendix A, the needed detail may not be in the chapter itself. Checking the appendix helps an instructor or applicant avoid missing required supporting information.
Intuition Check
Appendix does not mean the body organ here. In this context, it means an added section at the end of a written document.
Example Sentence 1
The instructor flipped to Appendix A to review the supplementary material referenced in the chapter on practical test recommendations.
Example Sentence 2
Before signing off the student’s logbook, the CFI reviewed Appendix A to make sure all recommended test elements had been covered.
