Fdgolf,
The majority of systems (flaps, electrics, spoilers, hydraulics, ECS, A/Ice) on the CL600/601/604 are very similar in operation to the RJ-200 but, as everyone has said, not close enough to claim any credit. The CL300 (ex-BD100) is completely different in both systems & avionics - not least of all the software-based menu selection of display contents & tuning from the Proline 21 avionics. The CL605 has similar displays & controls as the 300 but all the systems are the same as the 604.
