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

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
Significant changes in Avionics

• Three areas of change
• Satellite based navigation
• System integration
• Pathway presentation

12
Status of Global Navigation Satellite Systems
Satellite Based Navigation

• 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)

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

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
Current Areas of Concern

• WAAS LPV Approaches
• Misleading Approach Guidance during a WAAS LPV
  Approach is classified as Hazardous
• Use of FMS for WAAS LPV approaches
• Envelope Protection
• Implementation
• Human Factors elements
• New Avionics Suites
• Display compression
• What information to display
• Implementation of Highway In The Sky (HITS)

36
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

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 large reduction in safety margins or functional
  capabilities
• Physical distress or higher workload such that
  the flight crew cannot be relied upon to perform
  their tasks accurately or completely or
• Serious or fatal injury to an occupant other than
  the flight crew.
