PH.VIII.H — Dynamic Rollover

What does ACS code PH.VIII.H cover?

ACS Code PH.VIII.H covers "Dynamic Rollover" under Area of Operation VIII (Emergency Operations) for the FAA Private Pilot Helicopter certificate (FAA-S-ACS-15). Candidates are tested on knowledge elements and risk management factors defined in 14 CFR regulations and FAA handbooks (PHAK / AFH).

Airman Certification Standards Elements

Knowledge Elements

• PH.VIII.H.K1: Elements related to dynamic rollover.
• PH.VIII.H.K2: Interactions between thrust, crosswind, slope, lateral CG, aircraft weight, and flight controls that contribute to dynamic rollover.
• PH.VIII.H.K3: Preventive flight technique and recovery during flight operations, including slope operations.

Risk Management Elements

• PH.VIII.H.R1: Surface conditions conducive to dynamic rollover.
• PH.VIII.H.R2: Landing gear proximity to obstructions on the ground during low altitude hover.
• PH.VIII.H.R3: Flight control inputs during takeoff or landing.
• PH.VIII.H.R4: Sideward hover.
• PH.VIII.H.R5: Aircraft slope limitations.
• PH.VIII.H.R6: Critical rollover angle and rolling moment.
• PH.VIII.H.R7: Translating tendency.

How do I study PH.VIII.H?

1. Read each element for PH.VIII.H 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.VIII.H, and read the explanation for every miss.
4. Retest, then review the ACS codes you still miss on your practice test report.
