B777 MLG Bogie Assembly Question

Sat Dec 18, 2004 8:14 am

In looking at pictures on a.net, noticed that the last two wheels (or last axle ) moves side to side. Is this controlled by the tiller or by friction turning differential? Also is there a locking mechanism for T/O and landing?


Thanks

777 MLG steering is controlled by the MGSCU-Main Gear Steering Control Unit-which receives steering tiller position data from the NLG steering tiller position transducers. The system arms when it senses 13deg NLG steering input and disarms at less than 9deg NLG steering input. Center hydraulic pressure is used to actuate the main gear steering/locking power control actuator which is a two-way actuator with an internal lock for centering. The MGSCU supplies main gear steering position and fault data to the AIMS for flight deck indications and aft axle lock status to the warning electronic system for the CONFIG GEAR STEERING takeoff configuration warning.
