- 1). Look for a large aircraft. The Boeing 777 is the largest twin-engine jet aircraft ever built.
- 2). Look for a twin-engine jet, with engines mounted on pylons below each wing, but with most of the engine resting forward of the leading edge of the wing.
- 3). Note that the engines have a much larger diameter at front compared to the rear portion.
- 4). Consider the overall size of the airplane. The 777 seems too large to be powered by only two jet engines.
- 5). Check the landing gear. The 777 is the only twin-engine jet transport with six wheels on each gear assembly.
- 6). Note that the 777 does not have a tail cone. The fuselage terminates in a wedge shape that appears as a straight line when viewed from the side.
- 7). Remember, the 777 is distinctive because it has two passenger doors between the wing and the nose.
