This document supersedes DO-235. The earlier DO-235 assessments for Non-Precision Approach, Category I Precision Approach and Enroute/Terminal Area Navigation were reviewed and updated. Two new operational radio frequency interference (RFI) encounter scenarios were developed for aviation: Category II/III Precision Approach and GNSS-Guided Airport Surface Movement. With outside support three non-aviation scenarios were developed: Maritime Constricted Waterway, Airport Survey and GPS-based E911 in Cell Phones. The RFI source separation distance was reduced in the enroute and non-precision approach scenarios. All aviation approach scenario separation distances were assigned a probability factor compatible with operational continuity values.Seven major activities relating to ultra-wideband (UWB) interference to aviation systems, in general, and to GPS in particular were reviewed. UWB emission limits are proposed based on UWB RFI analysis of all the aviation and non-aviation scenarios. Mobile Satellite Service (MSS) interference, both Earth-space and space-Earth, were assessed in precision and non-precision approaches. Limits for MSS space-Earth unwanted emissions are proposed. Other potential RFI sources are reviewed and a set of RFI mitigations discussed.

DO-226, Guidance Material for Evolving Airborne Precision Area Navigation Equipment with Emphasis on MLS

Issued 5-25-95 s Superseded DO-198 (SC-151) s Prepared by SC-171

This document spans a decade of work by two RTCA Special Committees (151/171). During this period, alternative technologies to the Microwave Landing System (e.g., satellite navigation) have evolved. Yet the need for precision, near-airport area navigation continues. Whatever the navigation source for an operational capability, much of the material in this document is germane to any precision, terminal-area navigation system. The philosophy used in preparing the document was to provide guidance for any terminal area navigation system, although the specific performance requirements and test procedures assume the MLS Random (Area) Navigation (RNAV) sensor inputs.

Issued 4-19-00 s Prepared by SC-181

This document provides for the improved operational effectiveness of airborne navigation systems that use stored databases. It presents a collection of disciplines necessary to provide assurance that aeronautical information used by the aviation industry meets the high quality and integrity for safe flight. The information in the document has been compiled for the purpose of stating aeronautical information requirements of the aviation industry with emphasis on RNAV operations in RNP airspace. There is focus on the importance of quality aeronautical information and the fact that the evolution of computer navigation technology requires a greater dependency on the accuracy, reliability, integrity, and timely availability of navigation reference data than ever before. This is a joint RTCA/EUROCAE document.

Issued 9-12-94 s Errata 11-22-94 s Superseded DO-197 s Prepared by SC-147

Pertains to aircraft with up to 30 passenger seats as prescribed by the Federal Aviation Administration (FAA) TCAS rules. Active TCAS I is an air-to-air interrogation device that provides traffic advice to the flight crew by alerting them to the presence of a nearby transponder- equipped aircraft and advising the crew where to look for that aircraft so it can be visually acquired and avoided if necessary. Unlike TCAS II and TCAS III, Active TCAS I does not provide conflict resolution advisories.

Change 1, DO-197A

Issued 7-29-97

Analysis of data recorded from TCAS I equipped aircraft indicated that the TCAS I interference limiting algorithms were causing acquisition of intruders at low ranges and that the tracks were often intermittent. This change enhances the minimum TCAS I surveillance performance by refining the assumptions used in development of the original interference limiting algorithms. These modifications provide a significant operational benefit to the operators of TCAS I equipment, without increasing the total amount of interrogation power transmitted by TCAS I equipped aircraft. Power is reallocated to more closely reflect the actual operating environment.

DO-185A, Minimum Operational Performance Standards for Traffic Alert and Collision Avoidance System II (TCAS II) Airborne Equipment

Issued 12-16-97 s Prepared by SC-147

This document provides Version Downloadable 7.0 of the TCAS II logic and sets forth the minimum operational performance standards for TCAS II equipment. Among the changes, this Version Downloadable improves the system's surveillance performance and modifies the interference limiting algorithms to account for aircraft densities near airports as well as to permit longer range surveillance. Improvements have been made in tracking Mode S targets and in permitting TCAS to receive the extended Mode S squitter. To preclude repeatedly issuing Traffic Advisories (TA) against the same target, changes have been made to ensure that a target's TA status is maintained in slow closure situations by using more stringent drop criteria. Other changes include credibility checks to ensure integrity of the data being supplied to the collision avoidance logic and additional, more thorough tests for installed equipment.

Volume I contains the rationale for equipment characteristics, minimum performance standards, bench test procedures, and installed equipment performance. Volume II presents the required collision avoidance algorithms in a state chart formulation with informational commentary text. Attachment A provides both high and low level pseudocode representations of the collision avoidance algorithms. The standards and performance requirements in the document ensure that TCAS II is fully interoperable with other elements and equipment of the National Airspace System.

TASK FORCE REPORTS

Task Force 4, Final Report of the RTCA Task Force 4 Certification

Issued 2-26-99

Prepared by the RTCA Certification Task Force

Any improvements in safety, capacity, or efficiency will require some form of change. Prior to operationally implementing the improvement, equipment, procedures, and people will need to be “certified.” Experience, both prior to and during the Task Force, indicate that significant benefits will accrue to the entire aviation community if the process is “systems oriented” and if refinements are made to reduce the time and cost of the process thereby expediting the availability of the operational enhancements. The Final Report of the RTCA Task Force 4 Certification underscores the critical role of certification in achieving FAA's safety and modernization goals and provides 15 consensus-based recommendations for improving the certification process.

Issued 10-26-95

Prepared by Task Force 3

The Free Flight Implementation Task Force Report underscores the need for changes in the air traffic system and emphasizes that changes should be both benefits driven and implemented in steps, such that incremental changes lead immediately to incremental benefits.

This report provides the definition of free flight, addresses “dynamic density” plus other operational initiatives, and recommends a transition strategy based on the time-phased implementation of new procedures and technology. The strategy provides benefits to the entire air transportation community. The strategy also simultaneously moves the community from an analog communication, ground-based navigation air traffic control system to a digital communication, ground- and space-based navigation air traffic management system that makes increasingly heavier use of decision support systems to help air traffic service providers meet their important responsibilities.

Recommendations Regarding the Concept of Equipage and Mandated versus Voluntary Considerations

Issued 8-27-02

Approved by the Free Flight Steering Committee

This two-part document responds to the need for the aircraft equipage recommendations for realizing the benefit of capacity enhancement initiatives outlined in the Operational Evolution Plan. The objective of the Concept of Equipage work was to provide a recommended process and milestones to configure the fleet to achieve OEP capabilities. Four categories of capability were found to have avionics equipage implications: Domestic Reduced Vertical Separation Minima, Area Navigation, Controller Pilot Data link Communication, and Future air Navigation System 1A. In equipage related follow on work, additional detail will be obtained upon which avionic costing and installation time lines can be based. The second section of the document provides definitions of “mandated” and “voluntary” and offers recommended guidelines and criteria for FAA consideration when making mandated/voluntary equipage decisions.

Government/Industry Operational Concept for the Evolution of Free Flight, Addendum 3.1: Roadmap for Surveillance Modernization

Issued 8-16-00

Approved by the Free Flight Steering Committee

This addendum presents a consensus for the evolutionary modernization of surveillance capabilities in the National Airspace System (NAS) and is based on the operational objectives identified in the RTCA document, Addendum 3: Surveillance. Both documents are driven by the need to improve aviation safety, capacity and efficiency. This roadmap provides a set of target architecture characteristics that include delivery of a common surveillance “picture” to ATC service providers, flight crews, and airport/airline operational personnel; the utilization of “enriched” surveillance data for decision support tools, and reliance on ADS-B as the “cornerstone” of the future surveillance architecture. This document also identifies key business case considerations and activities that will appropriately justify both FAA and industry investment commitments.

Government/Industry Operational Concept for the Evolution of Free Flight, Addendum 3: Surveillance

Issued 8-16-00

Approved by the Free Flight Steering Committee

The Surveillance Addendum documents one of the essential elements of Free Flight and describes future capabilities that cover a period of approximately the next two decades. The document focuses on the operational use of surveillance, not the technical or architectural aspects of providing the information to those needing it. The approach described transitions from the current radar/interrogator baseline of surveillance information to a digital information environment that encompasses air and ground operations.

This approaches envisions providing shared real-time surveillance information to service providers (using automation to manage aircraft separation in all operation) and to pilots (utilizing new technology to aid in those aircraft management and separation services).

Future Flight Data Collection Committee Final Report

Issued 12-04-01

Prepared by the Future Flight Data Collection Committee

This report was prepared at the request of the FAA Administrator and the Chairman of the National Transportation Safety Board. The committee’s objective was to define operational concepts for acquiring, storing, and managing data concerning the state of the aircraft, operation of the aircraft, and air/ground and air/air communications. The document is intended to help identify recorded data requirements to industry in advance so the technology can be incorporated early in new designs, minimizing event-driven rulemaking. The final report contains seven recommendations that summarize the important issues and changes that

need to be considered in the area of flight data collection over the next 15 years. Appendices detailing the

work of the three working groups are included:

- WG-1, Data Needs

- WG-2, Technology

- WG-2, Data Use and Protection

Additionally, the report includes an appendix on deployable cockpit voice and flight data recorders.

Certification Steering Committee Final Report

Issued 08-31-01

Prepared by Certification Steering Committee

The Final Report of the Certification Steering Committee addresses the status of the 15 recommendations of the Certification Task Force, formed in 1998 at the request of the FAA Administrator. Over 200 members of the international aviation community participated in the Task Force to produce broad gauged recommendations for issues that were seen to introduce inefficiencies into the certification process.

The 15 Task Force recommendations address the following topical areas:

Organizational Focal Point in FAA

Systems Engineering Capability

Multi-tiered Airworthiness Requirements

Human Performance Considerations

Agreement or Regulator/Applicant Roles

Standardize Designee Programs

Early Deployment of Advanced Systems

Instrument Approach Procedures to Exploit Current Capabilities

Commonly Agreed Concept of Ops

Eliminate Duplicate Committees

Correct Misapplication of Rules

Certification Process Improvements

New Rule Harmonization

Publicize how Rules have been applied

A “No Fear” Feedback Process

RTCA formed the Certification Steering and Select Committees in response to the FAA’s request for a follow-on effort. The Steering Committee and its supporting Select Committee reviewed the 15 Task Force recommendations and documented FAA initiatives already underway for implementing certain Task Force

recommendations and provided proposals for implementing those recommendations not yet addressed. Each Task Force recommendation is cited and the action taken to respond to the recommendation is discussed.

The Authority of Agreement—A History of RTCA

William G. Osmun, a professional writer of note and longtime observer of RTCA activity, researched and wrote this volume under contract with RTCA. In this history, Osmun traces the effort of engineers, pilots, technicians, and other aeronautical experts to forge agreement out of conflicting desires and in the face of changing technology, government reorganization, and the tremendous growth of worldwide air service. For reference, appendices include a brief chronology of RTCA and tabulate the work of RTCA Special Committees and their chairmen, membership of the Executive Committee, Technical Advisors, and International Associates.
