Modern civil aircraft generally use electronic flight controlsystem (EFCS), which provide an electronic interface between pilot’s controls and control surfaces, generating the actual surface commands for control about all three airplane axes. The EFCS was required to meet the standards of the handling qualities rating method (HQRM). This unit is a space model of the EFCS Test/Failure Identification Panel control panel. The controls allow specific tests to be initiated and fault codes to be read out.
This unit also bears a green Dymo label marked 25/032
