GBAS Approaches – status update
Karl-Heinz Keller, Helmut H. Toebben · elib (German Aerospace Center) · 2009
Presentation on the technical features and operational benefits of Ground Based Augmentation Systems (GBAS in the US: LAAS). In the long run GBAS will replace ILS. GBAS is less expensive than ILS to maintain and acquire. GBAS provides several flight paths to be tailored regarding local restrictions like noise, glide path angle, obstacle clearances, s.o.. Operational benefits will have an impact on the capacity and will therefore be part of capacity studies when implementing new GBAS procedures.
