What was the purpose of Change 2 in the FAA-G-ACS-2?

• A. To remove an errant code from the 'Commercial Pilot for Airplane Category ACS Archived Codes' subsection.
• B. To add a new aircraft performance calculation method.
• C. To revise the entire section on flight testing.
• D. To delete all references to airspace.

Answer: (A)

Change 2 is a housekeeping update that cleans up the Commercial Pilot for Airplane Category ACS Archived Codes by removing an incorrect code. Archived codes are historical references used to annotate past items in the ACS documentation. If an errant code remains, it can cause confusion about what’s tested or how items are categorized. Deleting that erroneous code keeps the archived codes accurate and unambiguous, so pilots and instructors review only valid references that reflect the current standards. This kind of correction prevents misinterpretation and maintains consistency with FAA testing guidelines. The other options describe broader changes (a new calculation method, a complete revision of the flight-testing section, or removing all airspace references), which aren’t what this targeted update is about.
