FOREWORD
This document was prepared by Special Committee 186 (SC-186) and approved by the RTCA Program
Management Committee (PMC) on December 13, 2011.
RTCA, Incorporated is a not-for-profit corporation formed to advance the art and science of aviation and
aviation electronic systems for the benefit of the public. The organization functions as a Federal Advisory
Committee and develops consensus based recommendations on contemporary aviation issues. RTCA’s
objectives include but are not limited to:
•
coalescing aviation system user and provider technical requirements in a manner that helps government
and industry meet their mutual objectives and responsibilities;
analyzing and recommending solutions to the system technical issues that aviation faces as it continues
to pursue increased safety, system capacity and efficiency;
•
•
• developing consensus on the application of pertinent technology to fulfill user and provider
requirements, including development of minimum operational performance standards for electronic
systems and equipment that support aviation; and
assisting in developing the appropriate technical material upon which positions for the International
Civil Aviation Organization and the International Telecommunications Union and other appropriate
international organizations can be based.
The organization’s recommendations are often used as the basis for government and private sector decisions
as well as the foundation for many Federal Aviation Administration technical Standard Orders.
Since RTCA is not an official agency of the United States Government, its recommendations may not be
regarded as statements of official government policy unless so enunciated by the U.S. government
organization or agency having statutory jurisdiction over any matters to which the recommendations relate.
