Assignee: THE BOEING COMPANY
Field: Transport (Mechanical engineering)
Classification: CPC B  F | IPC B  F

Claim 0:
1. An aircraft comprising;
an airframe; and
an auxiliary power system structurally supported by the airframe and configured to regulate a bleed air temperature (BAT) of a bleed air flow, the auxiliary power system comprising:
(i) an auxiliary power unit (APU) configured to generate the bleed air flow;
(ii) an APU controller configured to receive and transmit signals; and
(iii) a BAT sensor configured to measure the BAT of the bleed air flow and configured to generate a BAT signal, wherein the BAT signal is based, at least in part, on the BAT;
wherein the APU defines a bleed air outlet;
wherein the aircraft includes a bleed air consumer, which is configured to receive at least a subset of the bleed air flow from the APU, and a bleed air conduit, which is configured to convey the bleed air flow from the bleed air outlet to the bleed air consumer;
wherein the BAT sensor is positioned at a remote BAT location that is spaced-apart from the bleed air outlet of the APU;
wherein the APU controller is configured to calculate a calculated BAT of the bleed air flow at a calculation location based, at least in part, on the BAT signal; and
wherein the calculation location is spaced-apart from the remote BAT location of the BAT sensor.
