Introduction of change 7.0 ACAS II and dual mode S transponders
Overview
Introduction
As specified in ICAO Annex 10:
ACAS I - provides information as an aid to “see and avoid” action but does not include the capability for generating RAs
ACAS II - provides vertical RAs in addition to TAs
Your needs
Currently, TCAS II is the only implementation that meets the ACAS ICAO Standards and Recommended Practices (SARPs). Therefore, the term ACAS II is typically used when referring to the standard or concept and TCAS II when referring to the implementation. However, often both terms are used interchangeably. In this Guide, the terms ACAS (the standard) and TCAS (the implementation) are used synonymously, unless specifically noted.
