ABSTRACT	The National Aerospace Laboratory （NAL）is developing a new in-flight simulator, named MuPAL （Multi-Purpose Aviation Laboratory）-alpha. This report deals with the method of designing a FBW（Fly-By-Wire）flight mode control law, named“228 mode”control law for the“Second Cockpit”of the MuPAL-alpha. The“Second Cockpit”is an experimental cockpit in the cabin designed to provide a flexible environment for research on pilot interfaces and effects of motion cues. The“228 mode”is a“direct link mode”which deflects the control surfaces to be proportional to pilot commands. The“228 mode”is used to check the FBW system function before engagement of the experimental control laws. The“228 mode”control law for the“Second Cockpit”has been designed to take into account feel（force versus displacement）characteristics, and the different force gradient for right and left roll commands for the sidestick, and to satisfy the handling qualities required to carry out mission tasks for the FBW system function check. A piloted flight simulation using a ground simulator was conducted to evaluate the handling qualities of this control law using the Cooper-Harper rating scale. The simulation results show that the “228 mode”control law designed for the“Second Cockpit”enables the pilot to carry out mission tasks for the FBW system function check and that the sidestick for the“Second Cockpit”is a useful control system for the MuPAL-alpha.
