AIRCRAFT INCURRED SYSTEMS FAILURES @ FL450 WITH 6 SOULS ON BOARD, 2 PILOT, 4 PAX WRITE UP AS INCURRED BY THE PILOTS. FL450 CRUISE LEFT PFD GOES DARK AP DISENGAGES NO YD MESSAGES BUT I CAN FEEL IMMEDIATELY THAT THE AIRPLANE STARTS TO SWAY BACK AND FORTH. CAS: AMBER L BUS FAIL AMBER L PITOT HEAT FAIL AMBER STALL PROTECTION FAIL CHECKLIST BOTTOM LINE IS LAND AS SOON AS PRACTICAL. DIVERTED TO KMCI ON THE DESCENT WE GOT AMBER L HYD TEMP HIGH WITH TEMPERATURE RISING AND REACHING 103°C. AT THAT POINT DECLARED AN EMERGENCY AND LANDED SAFELY IN KMCI. WE ARE OF THE ASSUMPTION THAT THE SYSTEM IN QUESTION COULD BE THE IAPS (INTEGRATED AVIONICS PROCESSING SYSTEM) WHICH COORDINATES THE TALKING OF ALL RELATED SYSTEMS. WE CURRENTLY HAVE TECHNICIANS FROM WEST STAR ON SITE AND WORKING THE EVENT TO GET A BETTER PICTURE OF WHAT COULD HAVE CAUSED THIS. DOWNLOADS FROM THE MAINTENANCE SYSTEM WILL BE PROVIDED TO BOMBARDIER FOR VERIFICATION.
