Is the Freewheeling unit located in the engine accessory gearbox (AGB) section?

• A. True
• B. False

Answer: (B)

The correct answer is that the Freewheeling unit is not located in the engine accessory gearbox (AGB) section. The Freewheeling unit is typically associated with the rotor system and is part of the system that allows the main rotor to turn freely in one direction, thereby enabling the helicopter to continue to fly safely in the event of an engine failure.

It is usually integrated into the transmission or rotor head area rather than being part of the engine's accessory gearbox. This position allows the Freewheeling unit to effectively manage the differential rotational speeds between the main rotor and the engine drive, facilitating better control and performance of the helicopter.

Understanding the locations of various components in helicopter systems is essential for maintenance, troubleshooting, and ensuring safe operational practices.
