Single-Aisle Aeroplane – the 737-900ER

Boeing recently unveiled the new 737- 900ER (extended range) aeroplane before thousands of employees and guests at the company's Renton, Washington., manufacturing facility.

The first 737-900ER will be delivered to Lion Air in the first half of 2007, following a five-month flight test program.

The 737-900ER is the same size as the 737-900, but can carry 26 additional passengers in a one-class configuration. At 138ft, 2 in. long, the twin-engine jet incorporates a new pair of exit doors and a flat rear- pressure bulkhead that allows a maximum capacity of 215 passengers in a single-class layout.

Aerodynamic and structural design changes, including strengthened wings, a two-position tailskid, enhancements to the leading and trailing-edge flap systems, and optional blended winglets and auxiliary fuel tanks, will allow the 737-900ER to accommodate higher takeoff weights and increase its range to 3,200 nautical miles (5,900km).

The 737-900ER claims to have substantial economic advantages over competing models including 9 percent lower operating costs per trip and 7 per cent lower operating costs per seat than the A321 – which is more than 10,000pounds (4,536kg) heavier.
