Implementation of Modern Aircraft Daily Inspection Mode by Using Solid State Power Controller

Abstract

This paper identifies the most promising Modern Aircraft Pre Flight/Daily Inspection (DI) Mode by using Solid State Power Controller. Daily inspection is required to be carried out as a preflight checks to ensure all systems are healthy and safe to take off. Aircraft Power Distribution plays a major role in Daily Inspection Operation. Depending on failure mode and type of operation these powers are managed by Power management system also called primary power Distribution system. This work identifies the Aircraft mode of operations and study the Daily Inspection requirement and efforts, and then implement the same by using Solid State Power Controller. Power to individual Load is provided with control and protection by secondary distribution system consisting of circuit Breaker panel and Switch Panel. Compared to circuit breakers and relays, the Solid State Power Controller (SSPC) has several functional advantages and is utilized for power control. Solid State Power Controller will keep an eye on the power distribution across the aircraft electrical system.  This device's MOSFET-based Solid State Power Controller is used for switching and amplifying weak electron signals. An aircraft's Electrical systems are being monitored by using the Daily Inspection mode. In this work, MATLAB Simulink is used to implement and simulate the Daily Inspection Mode. Through a two channel ARINC 825 Serial Communication Interface, SSPCs are interfaced with the monitored parameters of the Daily Inspection Mode
