DOC AIRBUS | AMM A320FSTARTING - GENERAL - DESCRIPTION AND OPERATION
** ON A/C NOT FOR ALL
1. General
The starting system of the engine utilizes pressurized air to drive a turbine at high speed. The turbine turning through a reduction gear, applies a torque to the HP shaft, thus driving the engine and the aircraft accessories. (See chapter 72-60-00) The air necessary for the starting is bled from the duct connecting engine bleed and the precooler via a 4 in.dia. duct. This duct is attached to the engine before the precooler inlet.
The air necessary for the starter is supplied by either:
