1 Presented to: By: Date: Federal Aviation Administration FLIGHT TEST SAFETY WORKSHOP Flight Test Safety Workshop Jim Richmond Aircraft Certification Service Flight Program Manager November 11, 2009 FAA Approval of Highly Integrated Avionics Systems

2 2 Federal Aviation Administration Aircraft Certification Service November 12, 2009 April 30, 2009 The Concern There are few specific rules or guidance for flight test of avionics systems While integrated cockpits improve situational awareness and safety, flight test must ensure pilots can effectively cope with new avionics in all situations Flight test knowledge of system architecture is essential in evaluating integrated avionics systems

10 10 Federal Aviation Administration Aircraft Certification Service November 12, 2009 April 30, 2009 Sources of FAA Policy for Avionics FAA Advisory material RTCA Documents –DO-178B SAE Documents –ARP-4754 –Policy Conflicts -- ARP takes precedence for software level determination

11 11 Federal Aviation Administration Aircraft Certification Service November 12, 2009 April 30, 2009 Significant changes in Avionics Three areas of change –Satellite based navigation –System integration –Pathway presentation

12 12 Federal Aviation Administration Aircraft Certification Service November 12, 2009 April 30, Status of Global Navigation Satellite Systems Global Constellations –GPS (24+) [31] –GLONASS (30) [20] –Galileo (27) [2+] –Compass (35) [2] Satellite-Based Augmentations –WAAS (3) –MSAS (2) –EGNOS (3) –GAGAN (3) –SDCM (2) Satellite Based Navigation

13 13 Federal Aviation Administration Aircraft Certification Service November 12, 2009 April 30, 2009 Current State of GPS Approaches WAAS performance standard released October 31, 2008 FAA has now published over 1,600 LPV approach procedures based on WAAS More WAAS-supported LPV approaches than Cat I ILS approaches WAAS-capable GPS receivers are specified in FAA Technical Standard Orders 145 & 146

34 34 Federal Aviation Administration Aircraft Certification Service November 12, 2009 April 30, 2009 Pathway Presentation LNAV/VNAV & WAAS based LPV Approaches –Transparent pathway Highway In The Sky (HITS) –Perception that this is new technology –Reality is that HITS is essentially a 3 dimensional flight director –Appropriate flight path guidance required Model is usually HUD based Flight path vector symbol

35 35 Federal Aviation Administration Aircraft Certification Service November 12, 2009 April 30, 2009 Current Areas of Concern WAAS LPV Approaches –Misleading Approach Guidance during a WAAS LPV Approach is classified as HazardousHazardous –Use of FMS for WAAS LPV approachesFMS Envelope Protection –Implementation –Human Factors elements New Avionics Suites –Display compression –What information to display –Implementation of Highway In The Sky (HITS)

36 36 Federal Aviation Administration Aircraft Certification Service November 12, 2009 April 30, 2009 To be remembered There are few specific rules or guidance for flight test of avionics systems Integrated cockpits can improve situational awareness and improve safety but flight test must ensure the pilot can effectively cope with the new avionics in all situations Knowledge of system architecture is essential in evaluating integrated avionics systems

38 38 Federal Aviation Administration Aircraft Certification Service November 12, 2009 April 30, 2009 Definitions Hazardous –Failure conditions that would reduce the capability of the airplane or the ability of the crew to cope with adverse operating conditions to the extent that there would be the following: a)A large reduction in safety margins or functional capabilities; b)Physical distress or higher workload such that the flight crew cannot be relied upon to perform their tasks accurately or completely; or c)Serious or fatal injury to an occupant other than the flight crew.
