APU logic

[Swagger897]

Currently APU bleed air is able to surpass it's ceiling of 23,000 feet.

 

Quote

The ECB controls the bleed load valve according to the demand signal from the Bleed Air Monitoring Computer. The BMC sends an open signal when the APU bleed switch is on, APU speed is above 95%, altitude is less than 23, 000 ft, and no leak detected except during engine starting.
