Boeing 777 Motor

That engine has exclusively powered Boeing’s 777-300ER since it entered service with British Airways in November 1995. With a maximum engine pod diameter of 166 inches, the GE-90 was previously the. Boeing 777 Now's the perfect time to extend your success. The Boeing 777's unique combination of superior range, outstanding fuel efficiency and passenger-preferred comfort has created long-range success for carriers around the world. And the 777-300ER now gives operators a perfect opportunity to extend that success.

The electric power system chosen for the Boeing 777 is an example of the advances seen in response to market demands for superior performance and reliability. The main electric system includes two engine-driven integrated drive generators, a generator driven by the auxiliary power unit, three generator control units, and a bus power control unit. A backup electric system independent of the main system provides the redundancy of electrical sources equivalent to a three-engine airplane, considering the auxiliary power unit inoperative. Both systems are automated to minimize crew workload.
The highly automated features of the 777 aircraft are enhanced by the equally sophisticated control units of the electrical power system. The state-of-the-art, microprocessor-based control units use a high-level software language to provide control and protection for the system, along with an elaborate built-in-test (BIT) capability.
Each control unit has two-way communication through a newly developed ARINC 629 communication bus. In addition to providing monitoring and built-in test information to the central aircraft information management system (AIMS) computer, an automatic checklist in each unit reports the real-time status of all main ac electrical power system control switches across the ARINC 629 communication bus for display in the flight deck.
