Ref the 757--
Do you mean the standard Boeing Close-in noise abatement procedure where you use V2+15 in the CLB page speed restriction to 3000 AFE, and select VNAV (CLMB 2) at 1500 AFE, accelerate and clean up at 3000 AFE?
The reason I ask is because we have a ridiculously dicked-up procedure that AWA uses on the Rolls powered 75 that requires us to do a manual thrust cutback at 1500' after fiddling with the FLCH and speed bugs at 400', and setting a manual cut-back EPR on the ground.
I remember doing the standard Close-in procedure using VNAV speed restrictions and CLMB 2 on TWA's Pratt airplanes and it didn't seem to ring the noise bells, but the honchos here insist it doesn't work on the Rolls airplanes.
It would be interesting to know if this is the case, or just a cultural resistance to change.
Thanks.

I've never done it in a 757. But that's what our Jepp 10-7 pages say. I've flown the S80 and the 737 both out SNA though.

Thrust - Use Max thrust, set CLB2;
T/O flaps - 15 preferred, 20 if required;
Program V₂+15 to 1550 ft MSL on CLB page;
When cleared to T/O, Hold brakes and stabilize thrust at 1.10 EPR; push EPR switch and release brakes; rotate to maintain V₂+15 at Vʀ; at precisely 800 ft AFE select VNAV and adjust pitch to maintain V₂+15; at 1500 ft AFE accelerate to Clean Maneuvering speed and retract flaps on schedule; at 3000 ft AFE accelerate to 250 kts.
Of course the VNAV engagement and lowering the pitch at 800 ft is noticeable and probably very uncomfortable for the nervous fliers. The trick (at least for me) is to remember to take the thrust off CLB2 about 5000 ft rather than at a much higher altitude.
Hope this helps.
Cheers,
