WAAS (Wide Area Augmentation System) An enhancement to the GPS systemproviding greater navigation accuracy and system integrity and permitting GPS to be used for precision instrument approaches to most airports.

Wide Area Augmentation System - U.S. based GPS augmentation system that uses ground-based stations to send position corrections to a constellation of geo-stationary satellites which in turn relay the corrections to WAAS/GPS receivers.
WGS 84 ...

wide area augmentation system - A navigation system developed by the Federal Aviation Administration, which is accurate down to three meters (approximately 95 percent of the time).

The Wide Area Augmentation System (WAAS) is a special system that supplements the space-based satellite signals of the primary GPS constellation.

WAAS (Wide Area Augmentation System)
WAAS can bring precision approaches to any runway.
RNP (Required Navigation Performance) is met by GPS with WAAS added.
RNP sets standards of accuracy, integrity, availability and continuity.

WAAS - Wide Area Augmentation System (in USA)
wake turbulence - wingtip vortices generated behind a wing producing lift. Behind a large heavy aircraft they can be powerful enough to roll or even break up a smaller aircraft.
