Built-in Test Equipment (BITE)

Description

Built-in test (BIT) is defined as an on-board hardware-software diagnostic means to identify and locate faults and includes error detection and correction circuits, totally self-checking circuits, and self-verification circuits. (Source: “Evaluation of Built-in Test”, by M. Pecht, et al, IEEE Transactions on Aerospace and Electronic Systems, Vol. 37. No. 1, January 2001.)

Built-in test equipment (BITE) is a self-function test integrated into airborne electronic equipment as a problem indicator. BITE functions and capabilities may include, among others, real-time monitoring, go/no-go indicators, degraded operation status, verification of system status.
