What does aircraft 73N mean?

73N means 737-700.

The N in 73N represents the next and new generation, which is also called Boeing 737NG

73N mainly includes Boeing 737-600/700/800/900 type. There are many models in China, which belong to the new generation of Boeing. The new generation is also divided into two types, one is the B73N and the other is the Boeing B73C. The Boeing B737-300/400/500 is more common.

How to judge whether it is a large aircraft or a small aircraft based on the description of the aircraft model?

If you follow a professional approach, there are many classification standards, such as weight, number of passengers, etc., but they are generally not suitable for ordinary passengers.

Let’s briefly talk about the common domestic aircraft types

D328-Dornier and CRJ-Challenger should all be small aircraft (this also includes the uncommon Xinzhou 60 , ERJ, ARJ and ATR72)

Boeing’s 737 series and Airbus’ A320 series are medium-sized aircraft, including B733/B734/B735/B736/B737/B738, respectively representing 737-300, 737- 400,..., B737-800 models, as well as A320, A321, A319 Airbus aircraft.

As long as the large aircraft has Boeing's 747, 767, and 777 models, they are represented as B747, B767, and B777 respectively (if you see B744 and B772, they represent the models of 747-400 and 777-200 respectively), Airbus's A300, A310, A340, A380, etc.

Boeing 737

The Boeing 737 series aircraft are twin-engine (engine) short- and medium-range transport aircraft produced by Boeing Company. They are known as the most successful civil aviation passenger aircraft in the history of world aviation and the largest in the civil aviation industry. All models of the Boeing 737 series have delivered more than 7,000 aircraft, which is more than the total delivery volume of Airbus.

No other aircraft model in the history of civil aviation has achieved such huge sales success. After receiving a start-up order for 10 aircraft from Lufthansa, the Boeing 737 aircraft began development in May 1964, using the nose and fuselage cross-section of the Boeing 707/727. The prototype flew in April 1967 and obtained the airworthiness certificate in December. , put into route operation in February 1968.
