How do I study PH.IV.E?

1. Read each element for PH.IV.E in FAA-S-ACS-15 and note any you cannot explain in your own words.
2. Study each one in the FAA source it points to: the handbook chapter, the 14 CFR section or the AIM paragraph.
3. Practice with questions tagged PH.IV.E, and read the explanation for every miss.
4. Retest, then review the ACS codes you still miss on your practice test report.
