Abstract
A method comprises receiving, by at least one processor remote from an aircraft, fault data automatically transmitted from the aircraft without initiation by a user on the aircraft and indicating a type of fault indicating a component on the aircraft that caused the fault. The type of fault is determined by analyzing parameter data generated by one or more sensors monitoring at least one parameter of the component. The method also includes analyzing, by at least one processor remote from the aircraft, the fault data to confirm whether the fault data correctly indicates the type of fault exists, and transmitting instructions to the aircraft to perform or not perform an act related to the fault.
Claims17
A method, comprising:
- receiving, by at least one processor remote from an aircraft, fault data automatically transmitted from the aircraft without initiation by a user on the aircraft and indicating a type of fault indicating a component on the aircraft that caused the fault, and wherein the type of fault is determined by analyzing parameter data generated by one or more sensors monitoring at least one parameter of the component;
- analyzing, by at least one processor remote from the aircraft, the fault data to confirm whether the fault data correctly indicates the type of fault exists;
- transmitting instructions to the aircraft to perform or not perform an act related to the fault;
- receiving parameter data that has one or more parameter values beyond a designated range of acceptable values but that does not trigger a conclusion of a type of fault exists and is not limited to being related to the received indication of a type of fault;
- automatically analyzing the parameter data to predict a future fault of a component on the aircraft;
- and
- warning a user on the aircraft of the future fault.
An aircraft, comprising:
- sensors monitoring components on the aircraft;
- processor circuitry forming at least one processor arranged to operate by:
- generating sensor parameter data by using the sensors;
- analyzing the sensor parameter data to determine if one of the components has a fault;
- generating fault data in the form of a fault tree indicating the type of fault;
- automatically transmitting the fault data without a user on the aircraft initiating the transmission;
- and
- receiving a fault confirmation transmission that provides an alert that confirms the fault exists and the type of fault or indicates the fault is a false positive,
- wherein the analyzing comprises determining whether a difference between expected parameter data and sensed parameter data is greater than a threshold.
A system, comprising:
- an aircraft, comprising:
- sensors monitoring components on the aircraft;
- memory;
- and
- first processor circuitry forming at least one first processor communicatively coupled to the sensors and the memory, and being arranged to operate by:
- generating sensor parameter data by using the sensors,
- analyzing the sensor parameter data to determine if one of the components has a fault,
- generating fault data in the form of a fault tree indicating the type of fault, and
- automatically transmitting the fault data including a fault tree code and without a user on the aircraft initiating the transmission;
- and
- a remote system remote from the aircraft, comprising:
- memory;
- and
- second processor circuitry forming at least one second processor communicatively coupled to the memory, and being arranged to operate by:
- receiving the fault data and decoding the fault tree code,
- analyzing the fault data to confirm whether the fault data correctly indicates the type of fault exists, and
- transmitting instructions to the aircraft to perform or not perform an act related to the fault, wherein the transmission of fault data from the aircraft only occurs when a fault is detected.
