Avionics

The Su-27's radar, its three displays, the HUD in the combat modes and the SPO-15 radar warning receiver.

The Su-27's avionics find other aircraft, show you where they are and warn you when they're looking at you. The displays are worked with the mouse in the cockpit view; the radar keys work in any view.
