Question on Engine Start
Hi,

For commercial aircrafts, APU bleed will help to start the engines. When we turn the ignition to ON and then select Engine 1, the startup is automatic. But I want to know a little more. When we select Engine 1 on the pedestal, does the APU bleed turn the low pressure compressor or turbine?

Care to share your knowledge?

Thanks
