Hope you can help?
We are in the process of redefining aircraft fuel tank and there might be a possibility that we may need to run the ECS (Environmental control system) pipe through the fuel tank? Would that be not possible (due to its size in diameter, thermal insulation, etc)? The same question goes for electrical wiring routes and the hydraulic lines? I understand that there are rules of segregating those, but what could happen if they are all installed in the tank? Thanks!
