CA.IV.K — Rough Water Takeoff and Climb

What does ACS code CA.IV.K cover?

ACS Code CA.IV.K covers "Rough Water Takeoff and Climb" under Area of Operation IV (Takeoffs, Landings, and Go-Arounds) for the FAA Commercial Pilot Airplane certificate (FAA-S-ACS-7B). Candidates are tested on knowledge elements and risk management factors defined in 14 CFR regulations and FAA handbooks (PHAK / AFH).

How do I study CA.IV.K?

1. Read each element for CA.IV.K in FAA-S-ACS-7B 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 CA.IV.K, and read the explanation for every miss.
4. Retest, then review the ACS codes you still miss on your practice test report.
