How do I study CH.IV.E?
- Read each element for CH.IV.E in FAA-S-ACS-16 and note any you cannot explain in your own words.
- Study each one in the FAA source it points to: the handbook chapter, the 14 CFR section or the AIM paragraph.
- Practice with questions tagged CH.IV.E, and read the explanation for every miss.
- Retest, then review the ACS codes you still miss on your practice test report.
