Hi captains,
Flying my B737-200...
I put the info on the PDCS Computer, for each pahse of lfight, TO-CLB-CRZ, Load page, etc... and press the ENGAGE button, and nothing happen. For example, reading the Boeing FCOM manual, theoretically when introduce the ZFW and other data for takeoff, pressing the engage button the EPR bug should move automatically to the position on the indicator,  but it doesn't happen like that. The PDCS is simulated??

thank's! :)
