First, the positioning is different
1, Boeing 767: It is a medium-sized, long-range, wide-body twin-engine jet developed by Boeing Company of the United States, which competes with Airbus A300 and A3 10.
2. Boeing 777: The long-range twin-engine wide-body passenger plane manufactured by Boeing Company of the United States is the largest twin-engine wide-body passenger plane in the world.
Second, the performance is different.
1, Boeing 767: automatic flight state adjustment control system, engine data display and alarm system are adopted, and all engine data are displayed digitally; Honeywell inertial coordinate system. Digital flight management system, three-dimensional digital flight control computer, including FCS-700 flight control system, EFIS-700 electronic flight instrument system and RMI-743 wireless electromagnetic display.
2. Boeing 777: small main landing gear, left and right three-axis six-wheels, complete circular fuselage cross section, knife-shaped tail. Boeing Company adopted many new technologies on the 777, such as all-digital fly-by-wire flight control system, software-controlled flight electronic controller, liquid crystal display flight instrument panel, extensive use of composite materials, optical fiber flight electronic network and so on.
Third, the advantages are different.
1, Boeing 767: It is Boeing's first glass cockpit, which can accommodate two passengers. The cockpit design of Boeing 757 and 767 is the same, so it is easy for crew and maintenance personnel to master both aircraft at the same time.
2. Boeing 777: The third-class passenger capacity ranges from 283 to 368, and the voyage ranges from 5,000 nautical miles to 9,000 nautical miles.

Boeing 777 detailed parameters Boeing 777 wingspan: 60.93 meters; Captain: 63.73 meters; Standard three-level cockpit layout capacity: 320 people; Two-level layout carries passengers: 440 people; Cargo hold capacity:160 l; Maximum commercial load: 54 tons; Maximum fuel tank capacity:117340l; Maximum takeoff gross weight: 230 tons; Maximum voyage: 9525 kilometers; Power plant: two turbofan engines.
Boeing 777 is a twin-engine wide-body airliner developed by Boeing Company of the United States. One of its most obvious identification marks is its three-axis six-wheel main landing gear system and two front wheels. This structure not only effectively disperses the road load, but also makes the landing gear strut of the aircraft not more than three.

Main models of B777
I. B777-200 type, basic type.
2.B777- 200ER(IGW) and 200 extended range models, by changing the internal structure, increase the total takeoff weight and fuel load, so that the maximum fuel range can reach 14000 km.
3.B777-300 is an extended version of Model 200, the longest twin-engine jetliner in the world, which is10m longer than Model 200 and 3.2m longer than Boeing 747-400. It has the same fuel load as the 200IGW model, and the range can reach 1 1000 km.
The passenger capacity of Boeing 777-300 is the same as that of Boeing 747- 100/-200. Fuel consumption is reduced by one third, and maintenance costs are reduced by 40%. This can meet the needs of customers who want to replace early Boeing 747 models.
Public trust. Brief Introduction of Boeing B777 Series Aircraft
