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?

I don't read where he said WAAS is the enabling factor for track-guided
procedure turns or holding patterns.
