Why you said precharge is not correct. Its the value of precharge pressure in Boeing-NG plane & i dont know the value in other aircraft. And yes by saying it goes to 3000 psi after getting
pr from hyd sys, my mean is that total accumulator
pr available for braking is 3000 psi as soon as
brake system hyd is ON (Sys B in Boeing NG). The indicator in cockpit shows the total available
pr at any time which is composed of precharge & hyd fluid.
Thanks
