Description / Abstract:
This document contains the Minimum Aviation System Performance
Standards for the Local Area Augmentation System (LAAS), a system
developed to support precision approach and landing operations and
other navigation and surveillance applications, within a local area
including and surrounding an airport.
This revision harmonizes the LAAS requirements for supporting
Category I operations and the LAAS differential positioning service
with the LAAS MOPS [DO 253A] and the ICAO Annex 10 GBAS SARPs
through Amendment 79. The requirements to support LAAS Category II
and III precision approach operations are added/updated as well as
requirements for the LAAS when supporting complex terminal
procedures through the broadcast of Terminal Area Path (TAP) data
using the LAAS VHF Data Broadcast (VDB).
