Jet Aviation’s Zurich maintenance center has installed a precision area navigation system (P-Rnav) in a Cessna Citation III, a first for the model. P-Rnav equipment provides the improved track-keeping accuracy that is required in some European terminal airspace. 

The 22-year-old business jet’s cockpit also received a new Honeywell weather radar, cockpit voice recorder, enhanced ground proximity warning system and runway awareness and advisory system. The avionics retrofits, completed to the latest standards of the European Aviation Safety Agency, were made while the airplane underwent a cabin makeover that included a new seating configuration and soundproofing upgrade.
