How many sprags are contained in the freewheeling unit's clutch?

• A. Two
• B. Four
• C. Six
• D. None mentioned

Answer: (D)

The freewheeling unit's clutch is designed to allow the engine to freewheel without engaging the transmission when the aircraft is descending or if the engine is not providing power. In this context, the term "sprags" refers to the one-way clutch mechanisms that enable this function. The design specifications for the freewheeling unit do not indicate that a specific number of sprags is a standard part of the mechanism; thus, it is accurate to say that the number of sprags is not specified in the documentation related to the unit. This means that potential answers mentioning two, four, or six sprags are not supported by available information, aligning with the conclusion that none are explicitly mentioned. Hence, the correct interpretation is that there is no definitive count of sprags noted in the documentation.
