Collins Aerospace Pro Line 21 innovations for the business jet include four 12 x 10-inch adaptive flight displays. Standard pilot and copilot primary flight displays (PFDs) are teamed with dual multifunction displays (MFDs) and dual Collins FMS-6000 Control Display Units (CDUs) to streamline and automate input functions. All primary flight, navigation, engine and sensor data are graphically presented for easy scanning and integration. The large displays allow Challenger 605 pilots the operational benefits of more display area without the weight and power requirements of previous generation aircraft display systems.
