LAAS is an example of GBAS.

• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (A)

LAAS is a Local Area Augmentation System that provides corrections and integrity information for GPS signals within a limited area around an airport. GBAS stands for Ground-Based Augmentation System, which describes exactly this approach: a ground facility at the airport computes and transmits corrections to improve GPS accuracy, integrity, and availability for precision approaches and landings. Because LAAS delivers localized GPS enhancements from the ground to aircraft in the airport vicinity, it fits as an example of GBAS. For contrast, WAAS is a Wide Area Augmentation System, part of the satellite-based augmentation family, not GBAS. So the statement is true.
