Next-Generation 737-900ER Takes Maiden Flight

Wed Sep 06, 2006 3:26 am



SEATTLE, Sept. 05, 2006 -- The newest member of the Boeing Next-Generation 737 airplane family took to the skies over Washington state Friday on its maiden flight. Painted in the Boeing blue-and-white livery, the 737-900ER (Extended Range) took off at 9:21 a.m. PDT from the Renton Municipal Airport in Renton, Wash. The first flight marks the beginning of a five-month flight test program to obtain certification of the airplane from the U.S. Federal Aviation Administration and the European Aviation Safety Agency by early 2007.

...During the flight, tests were carried out on the aircraft’s airworthiness, aerodynamic performance, stability and cruise performance. Flight controls, the autopilot, pressurisation, avionics, air conditioning systems and the flight management computer were also tested.

Two aircraft will be used for the flight test programme, accruing a combined total of 235h of flight testing and 210h of static ground testing.

Both test aircraft will be delivered next year to Lion Air, launch customer for the 737-900ER.

Thank you for the update. I really hope the 737-900ER will do well!! It should be able to be produced in more than dear I say 250 examples. Boeing's own estimate is 200 over the next 20 years if IIRC

When Boeing says early 2007, does anyone know exactly when? Is that January or March?

The -900ER have the same fuselage as the rest of 737NG, exept for the extra fueltank?

Not just the fueltank - additional features are an additional pair of exit doors, a flat rear pressure bulkhead, a two-position tailskid, wing strengthening changes and enhancements to the leading and trailing edge flap systems.

two-position tailskid

What is this feature? What is it for? How does it work?

Do you know where I can see a photo of this two-position tailskid?

What's a flat rear pressure bulkhead?

Also, does anyone have a diagram showing the difference between the regular -900 and the -900ER?

It's a feature to help protect the aircraft in case the pilot pulls up too much on take-off and the tail section strikes the runway. You can see it in the first picture the thread starter posted. I am not sure, however, what they mean by 2-point...?

Here is a picture of one on a B-29:

The old B707-400 series used to have a similar thing under the tail end of the aircraft....I always wondered what it was......was this a 'tail skid'?

Aft pressure bulkheads are generally round or domed shaped. But the B727 and DC-9 MD80 717 A/C all had flat aft pressure bulkheads but they also had pressure doors on the bulkhead the 737ER does not. I would imagine that the balkhead is flat to accommodate more seating. http://www.airliners.net/open.file/0703529/M/ http://www.airliners.net/open.file/1092758/M/
