Thanks to the certification and AML STC approval, owners of Garmin's popular
GNS 400/500 series panel-mount avionics will be able to upgrade their
products to meet the FAA's WAAS standards* without a field approval**. These
upgrades include 5 Hz position updates, faster map redraws, fully coupled
and guided procedure turns and holding patterns, and increased XM weather
content. Pilots will also experience significantly enhanced functionality
because of the WAAS LPV, LNAV/VNAV, LNAV+V, and LNAV approach capabilities.

Coupled procedure turns and holds? Why is WAAS an enabling factor for
that?

Thats pretty interesting. Go missed and hold. I'll just take a little
break :-)
