Which aircraft type is included in the narrow body category?

The A320 is accurately classified as a narrow-body aircraft. Narrow-body aircraft are designed with a single aisle, which typically limits passenger capacity compared to wide-body aircraft that feature dual aisles. The A320 series is well-known for its efficiency on short to medium-haul flights and is widely utilized by airlines around the world for its ability to accommodate a moderate number of passengers while still providing operational flexibility.

In contrast, the A400M is a military transport aircraft that falls into a different category altogether, focusing on cargo transport and tactical airlift missions. The B787, also known as the Dreamliner, is categorized as a wide-body aircraft, characterized by its two aisles and larger passenger capacity. Similarly, while the B737MAX is historically considered a narrow-body aircraft, the specific mention of the A320 as a dominant representative in this category makes it the most recognized answer in the context of narrow-body classifications.

Thus, while B737MAX is also a narrow-body, the A320 is included as a well-established example within that category.
