A bleed leakage detection system includes an arrangement of thermostats that are capable of detecting the place where the bleed air leakage is occurring (e.g., the failed junction in bleed air duct work). The exemplary illustrative non-limiting implementation provides a bleed leakage detection system with continuous monitoring of thermostat sensor wiring during flight and thermostat self-test function (“Initiated Built In Test”—“IBIT”). The IBIT self-testing can be initiated before the aircraft takes off or optionally, during periodic self testing that may be run during predetermined periods such as overnight when the aircraft is not being flown. By the continuous monitoring the pilot is alerted when a bleed leakage has occurred or when the bleed leakage detection system has failed. |
