Built-in test equipment (BITE) for
avionics
Avionics (a blend of ''aviation'' and ''electronics'') are the electronic systems used on aircraft. Avionic systems include communications, navigation, the display and management of multiple systems, and the hundreds of systems that are fitt ...

fault management
In network management, fault management is the set of functions that detect, isolate, and correct malfunctions in a telecommunications network, compensate for environmental changes, and include maintaining and examining error logs, accepting and ...

Built-in test equipment includes
multimeter
A multimeter is a measuring instrument that can measure multiple electrical properties. A typical multimeter can measure voltage, resistance, and current, in which case it is also known as a volt-ohm-milliammeter (VOM), as the unit is equipped w ...

A signal generator is one of a class of electronic devices that generates electrical signals with set properties of amplitude, frequency, and wave shape. These generated signals are used as a stimulus for electronic measurements, typically used i ...
s that are provided as part of the system to enable testing and perform diagnostics.
The acronym BIT is often used for this same function or, more specifically, in reference to the individual tests.
BIT often includes:
* The detection of the fault
* The accommodation of the fault (how the system actively responds to the fault)
* The annunciation or logging of the fault to warn of possible effects and/or aid in troubleshooting the faulty equipment.
Functionality
* Analysis of failure monitoring results
* Reporting and memorization of failures
* Management of tests

Built-in self-test
A built-in self-test (BIST) or built-in test (BIT) is a mechanism that permits a machine to test itself. Engineers design BISTs to meet requirements such as:
*high reliability
*lower repair cycle times
or constraints such as:
*limited technic ...

Software fault tolerance
Software fault tolerance is the ability of computer software to continue its normal operation despite the presence of system or hardware faults. Fault-tolerant software has the ability to satisfy requirements despite failures.
