A320 braking LP distribution line
Heya guys. Just looking for a little help in understanding a schematic in the FCOM (for non ABCU systems).
What is the Auxiliary LP distribution line?

Normal braking is by electrical signal. The line you mention is for when this has failed..
Alternate Braking without Anti Skid The Alternate braking without anti skid system is the secondary mode of operation of the Alternate braking with anti skid system. The system is auto-matically available when the anti skid function is not available. This occurs when:
� the A/SKID & N/W STRG switch is set to OFF
� electrical control of the Alternate Braking with Anti Skid System is not available. The system uses the same hydromechanical components as the Alternate braking with anti skid system. Braking inputs can only be made at the brake pedals. When the brake pedals are operated, hydraulic pressure from the Yel-low main hydraulic power system is connected to the brakes. If the Yellow hy-draulic supply is not available, an accumulator (filled from the Yellow hydraulic system) give sufficient pressure for at least 7 full operations of the brakes. As electrical power is not necessary to operate the brakes, this system is usually used when the aircraft is towed. A triple pressure indicator shows the supply pressure and the pressure at the brakes.
