Advanced navigation technology developed for the
            A320 Family is available on the A319.  The use of RNP-AR (Required
            Navigation Precision – Authorisation Required) procedures combined with
            RTA (Required Time of Arrival) operations eliminates the need for holds
            during a flight, and enables a continuous descent approach.  The net
            benefits are lower noise and reduced fuel burn, as less engine thrust is
            required.
            
            The A319 shares the same fly-by-wire flight controls
            and state-of-the-art cockpit as the other A320 Family members,
            profiting from the unique benefits of Airbus operational commonality. 
            All of these aircraft – the A318, A319, A320 and A321 – share the same
            pilot type rating.  With only minimal additional training, A320
            Family-rated pilots can quickly transition to Airbus’ widebody
            jetliners.
