Is this a fix for past problems (other models of Airbus) or just a tweak that might be beneficial?
EASA certifies new Auto-Pilot/Flight-Director TCAS mode for A380
Friday August 21, 2009
EASA certified a new Auto-Pilot/Flight-Director TCAS mode for the A380 that Airbus said "essentially completes the existing TCAS functionality by implementing a TCAS vertical guidance feature into the Auto Flight computer." It explained that "the main benefit" is that "the pilot can now fly the aircraft without switching out of one mode and into another. . . This enhanced TCAS mode minimizes potential overreactions or inverse reactions while preserving concentration at a critical time." In addition to being certified on the A380, the AP/FD TCAS mode will become available for retrofit on other Airbus fly-by-wire aircraft, the manufacturer said.
