In most cases, the strobe lights (blinking bright white) on both sides of the wing flash twice are Airbus series aircraft

Boeing aircraft also have a flashlight behind the wing tip. Equipped with always-on positioning lights (always-on white)

So it is easier to distinguish at night. If the strobe light flashes once, it is a Boeing series aircraft with positioning lights. The strobe light flashes twice. Airbus series aircraft do not have position lights.

In addition, Boeing aircraft have now introduced LED into the lighting system. Boeing 787, 747-8, and some new 737 series aircraft all use LED lights, which are very easy to identify at night.

Then there are some models that are difficult to identify

The 737 and 320 are actually easier to identify. The biggest difference between the 737 and the 320 is that the 737 aircraft is shorter and has an engine inlet. It is not round, and the lowest part from the ground is flat. This is one of the most typical features of the 737 series aircraft.

The 777 and the 330 are also easy to identify. The 777 uses beveled winglets, while the 330 Traditional winglets are used. The APU vents on the butt of the 777 are biased to one side rather than symmetrical, while the 330 is symmetrical. The 777's tail is smooth and transitional, while the 330 has a tall curve. The landing gear of the 777 has three pairs of six tires in each group, while the 330 has two pairs of four tires. This is the easiest difference to tell.

747 and 380 are easier to identify. The upper deck of 747 is much shorter than that of 380. This is the biggest difference. Needless to say

The 787's winglets are tapered, while the 350 uses fused winglets, which are also easy to distinguish

The A340 series has almost the same features as the 330 The same fuselage, but with four engines, is easy to distinguish. The 340-600 fuselage is more slender

Then there are some models that may be easily confused, namely B757, B767 and A300 A310. Aircraft

The 757 is easily confused with the 321. Both have a similar appearance and slender fuselage. However, each set of the 757's main landing gear is composed of two pairs of four tires, while each set of the A321's main landing gear has a pair of two tires.

The 767 is fatter than the 757 and thicker than the A330. Short

A300 and A330 are very similar. The biggest difference is that the winglets of A300 are very small. There are many A300s without winglets

A310 looks similar to A321 at first glance. The A300 is shorter and uses a winglet shape that is very similar to the A321. It is symmetrical up and down, but it is much fatter than the A321
