Rockwell Collins Delivers 500th HGS to Southwest Airlines

Rockwell Collins says it has delivered its 500th Head-up Guidance System (HGS) to Southwest Airlines.

Southwest's new B-737-700s have the HGS-4000 installed, which besides CAT (category) IIIa approach capability, also feature guidance information on runway remaining, tailstrike avoidance and unusual attitude recovery.  In addition, the HGS-4000 has an anomaly detection capability that filters out disturbances to ILS (instrument landing system) signals during the final approach phase. And in the future, it should allow Southwest to conduct GPS-based approaches to lower than standard Cat I minima, according to Rockwell Collins.  10-12-2007.
