I shutdown my right engine, dumped some fuel and headed back to land. I used flap 20, don't know if that's right and auto-brake 4. I was landing on runway 24R and Manchester and the braking was very light. I noticed by R HYD system was gone. Will that affect my braking?Regards,(I left the runway via the grass) :-(

Your question involves several topics. I will try to answer, but probably real life pilots or enginerers will be more accurate on this one.*First, the right engine shutdown *should not* cause low pressure in the right hydraulic system. You should check that the right hydraulic demand pump (electrically-powered) is "ON". If not, maybe you have also a right bus unpowered (see the electrical panel)*Second, braking power is not affected by a right hydraulic failure, because there is a backup from the center circuit.*Third, the right hydraulic failure will cause autobrake failure (you should see an "autobrake" advisory message on upper EICAS).Thus I guess the "light braking" you describe was in fact ineffective autobrakes, due to right hydraulic failure triggered by the right engine shutdown in conjunction with another failure or simply a bad configuration of your hydraulic (or electrical) panel.Is that clear enough *:-* Regards,Laurent Crenier_____________________________767PIC Panel co-designer

* Fourth, this 767 doesn't have fuel dump capability.Lee Hetherington (KBED)

Your right. It doesn't have fuel dump capability, but you if you feel you must dump fuel to get to MLW, you can always cheat by pausing the simulation and selecting Aircraft options, and then select 30 % for the right, left and 10 % or whatever to meet the landing weight envelope and then proceed with the landing phase.Regards,

Thanks guys, I know what happened now!

Just wanted to add that the lack of fuel dump capability is realistic: Many 767s don't have fuel dump cabability.If you need to land above MLW, do it carefully and don't slam the plane into the ground! :-)Martin767 fetishistIt's a lot like life and that's what's appealing

I believe I've seen the procedures for such a greater than MLW landing. If it wasn't possible to land right after a MTOW takeoff, the plane would have to have fuel dump capability.Lee Hetherington (KBED)

Hey guys,I am reasonably certain that the 767-300 was required to have a fuel dump system installed as part of its airworthiness certification approval. It is not an option; it is part of the type design.The FAR requirement pertaining to fuel jettison systems is 25.1001. Basically, it says that the airplane must meet the approach and landing climb performance requirements at its maximum takeoff weight less the fuel needed for a 15-minute circuit. In addition to this basic rule, there are other issues that need to be addressed such as landing distance, brake energy capability, flap placard speeds, etc.Don S.
