Which statement correctly distinguishes Category A from Category B rotorcraft regarding engine failure?

• A. Category A rotorcraft are designed to meet Part 29 standards with engine-out performance; Category B rotorcraft do not guarantee stay-up after engine failure.
• B. Category B rotorcraft meet stricter standards than Category A.
• C. Category A rotorcraft never experience engine failure.
• D. Category B rotorcraft are used only for agricultural operations.

Answer: (A)

Engine-out performance is a key certification concern for rotorcraft. Under Part 29, Category A rotorcraft are designed to meet stricter engine-out standards so that, if one engine fails, the aircraft can maintain safe flight and reach a suitable landing area. This stay-up capability is part of what distinguishes Category A from Category B. Category B rotorcraft do not carry the same guaranteed engine-out performance, so there isn’t the same assurance of staying aloft after an engine failure. That’s why the statement saying Category A rotorcraft are designed to meet Part 29 standards with engine-out performance and Category B rotorcraft do not guarantee staying up after engine failure is the best description. The other options aren’t accurate: Category B doesn’t exceed Category A’s standards, engine failure can and does occur, and certification categories aren’t defined by agricultural use.
