Onboard radar display for VFR collision avoidance

In VFR (visual flight rules) situations the pilot is responsible for collision avoidance. This can be problematic in case of high-speed business jets entering the vicinity of a local airport. Often, this airspace is occupied by slow, low-visibility aircraft like gliders, ultralight vehicles or, occasionally, balloons. These may be not equipped with active transponders. Thus, it is up to the pilot of the jet to take care of see-and-avoid separation.
