 A. Bleed Air Supply Source from the HP Ground Connection
 NOTE : The HP ground supply source must be able to give a pack inlet
____ pressure of 24 PSI minimum. If it can not do this then you must get the bleed air supply from the engines. The work steps which follow show the conditions necessary before you get the minimum pack-inlet pressure.
