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 Sukhoi and Antonov.

Popular Twin-Engine Narrow-Body Airliners in Service

The chart below shows a side-by-side comparison of popular twin-engine narrow-body jetliners in service today, including the Boeing 737, Airbus 320 and the Embraer E175. It also includes the Bombardier CS100 now being delivered.

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 A320 has two engines under the wings, two dual-wheel main landing gear, two cabin doors along the fuselage, two emergency exits over the wing, and the classic Airbus nose featuring the "notched" window.\

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.

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

The Antonov Company product line includes a range of regional passenger planes, from the 27−seat turboprop Antonov An-38 to the Antonov−148 and Antonov−158 jets.

The An-148/158 airliner is a high-wing monoplane with two turbofan jet engines mounted in pods under the wing. Seating arrangements can be configured for 68-99 passengers.

The An-148 and An-158 are capable for use at poorly equipped airfields due to its built-in auto-diagnosis system, auxiliary power unit, high reliability, and its wing configuration.

Over 40 Antonov An-148/158 series airliners are in service at several airlines.
