Northwest 757's

Sun Aug 31, 2003 10:50 pm

Does Northwest still have Rolls-Royce powered 757's? We all know factory fresh Northwest 757-251's are Pratt-Whitney powered 757's but when Northwest took delivery of its first 757-200 back in the mid 80's it merged at the same time with Republic which operated at the time RR powered 757's. I'm just curious to know if there are still RR powered 757-2S7's currently in service at Northwest. Northwest 757-300's are all factory fresh PW powered. I know there have been lots of discussions about Northwest DC-9's and DC-10's but this one is about the 757.

None left; All of the RC 757s (6 I think) went to America West shortly after the merger

Nope, I think all have been converted to PW. I flew on a NWA 757 a few weeks ago that wasn't new, and it was PW.

As far as I know is the entire 757 fleet powered by PW engines and that the RR powered 757 were changed with Boeing on an one to one basis.

They were traded to Boeing leasing company for payments on 757's they had on order in June/July of 1987. The cabin layout was different to. Galleys and lavs set up differently. If the RC 757's were PW powered, they would've kept them and reconfigured them. like they did with the 727's. They were alot easier to work with. The F/C galley on the RC 727's has carts for the F/C service.

BillElliott is correct. The aircraft were NOT converted, they are indeed all in the America West fleet as N901AW/N906AW.

I remember reading that they went to Republic soon after the merger, but I seem to recall Northwest 757s flying in the interim colors (white fuselage with red stripe and red tail) for some time after the merger.

Currently the six ex-Republic RR RB.211-powered 757's serve with America West airlines as N901AW through N906AW.

Northwest, and Delta, were actually the launch customers for the PW powered 757's in the mid 80's. I believe that the PW2000 series engine is more fuel efficient that the RB211, but I could be wrong.

They cannot just decide to put PW engines on an A/C that has been rigged for RR. The PW engines use what is called a FADEC, full authority didgital engine control, to control the fuel metering and other engine operations. There is no physical connection between the thrust levers in the cockpit and the engine only a wire bundle. The RR engines use a regular hydromechanical fuel control, but they added a computer, an EEC or electronic engine control, that does the final fuel metering. Since the RR has an old fashion fuel control as part of its fuel metering system there is a cable and pulley system from the thrust levers to the engine.

differences between PW powered 757s and RR powered 757s are more than skin deep.

An additional note; at least a few of the former RR powered NW 757s now in the HP fleet carry the special liveries (ie, OHIO,NEVADA,ARIZONA,SUNS,DIAMONDBACKS,CARDINALS etc.)

Though I am not aware of the details concerning the dealings by which ex-Republic RR-powered 757s passed from Northwest to America West, I can recall observing at least one 757 in full HP livery of the time in the massive NW hangar at MSP located near the holding point for 28L. That was in the Summer or Fall of 1987, before any 757 had enetered service with HP. NW did indeed operate all 6 of the ex-Repulic 757s for a short time (less than 1 year) after the merger -- in my spotting and photography at MSP in the Spring of 1987, I regularly observed these aircraft operating NW flights in the basic Republic final livery (gray and red) with Northwest titles and red tail, as well as some in full Northwest livery of the time.

ALL NWA 757's are PW powered now.

They are more fuel efficent and last alittle longer then the RR RB211 but hmmmm the sound and the power you get out the RR engines is worth the extra money and maintnace/fuel cost.
