Displays are controlled by the Instrument Control Panel (ICP). There are separate ICPs for piltot's and co-pilot's side. 

• ▲ Zoom out (Sector Mode, this is synchronized for pilot and co-pilot)
• ▼ Zoom in (Sector Mode, this is synchronized for pilot and co-pilot)
• PFD Toggles PFD's Composite Mode
• ND Toggles ND's HSI Mode and Sector Mode
• NAV SOURCE Changes navigation source: VOR1/ILS1, VOR2/ILS2, NMS (GPS)
• ↑ Needle to ADF1 or VOR1
