Spotting Narrow-Body Airliners with 2-Engines Under Wings


The airliner is a narrow-body, and has two engines under the wings ... what type of aircraft is it?

Most jet airliners in service today have two engines, one under each wing, including those manufactured by Boeing and Airbus.

Boeing continues to manufacture the highly successful twin-engine, narrow-body 737 series, while Airbus produces large numbers of its A320 family. The Boeing 757 twin-engine is out of production but still in active usage.

The Bombardier CS Series and Embraer E-Jet also have one engine under each wing, as do the regional jets from Antonov.

Twin-Engine Narrow-Body Boeing Airliners

Boeing continues to manufacture the highly successful 737 series, with thousands in service around the world, including the popular 737-NG models.

The Boeing 737 has two engines, a main landing gear consisting of two sets of two wheels, and a triangular section at the front of the tail. The nose is "pointed".

Twin-Engine Narrow-Body Airbus Airliners

Airbus produces large numbers of its highly successful A320 family, including not only the A320, but also the A318, A319 and A321.

The narrow-body Airbus A320 has a rounder nose than Boeing jets and no leading edge "triangle" in front of its tail. The A320 was shortened into the A318 and A319, and stretched into the A321. All have similar design features.

The typical Airbus A320-series airliner has a "rounded nose", a windshield straight across the bottom, and its rear windshield window "notched" at the top.

Embraer and Bombardier Twin-Engine, Wing-Mounted Narrow-Body Airliners

Embraer and Bombardier are also manufacturing a series of narrow-body, single-aisle airliners with twin wing-mounted engines.

Embraer builds the Ejet and Ejet E2 series, while Bombardier builds the C Series airliners.

Mitsubishi Twin-Engine, Wing-Mounted Narrow-Body Airliners

Under development is the Mitsubishi Regional Jet (MRJ), which had its first flight in November of 2015. This airliner will have two engines, one under each wing, and carry from 70-90 passengers.
