Which statement correctly compares the widths of the two ranges?

• A. The gen cut-in range is wider than the gearbox shift range.
• B. The gen cut-in range is narrower than the gearbox shift range.
• C. The two ranges have the same width.
• D. The gen cut-in range is unrelated to gearbox shift width.

Answer: (B)

Range width is the span between the start and end points of an operating window. The generator cut-in range is the window during which the generator starts contributing power, and it’s designed to be a relatively tight, specific band to keep electrical load and engine behavior balanced. The gearbox shift range, on the other hand, covers the conditions under which the transmission changes gears, which typically extends over a broader range of engine speeds to allow smooth shifts across multiple gears. Because the generator cut-in window is narrower, it has a smaller width than the gearbox shift range. Therefore, the statement describing the gen cut-in range as narrower is the best choice.
