Economize real-time simulation

• Why real-time simulation?
• What has changed?
• Where to economize?
• The Proposal

3
Why real-time simulation?

• To identify human responses to
• Man-machine-interface and technical systems
• Human cognition / reaction to new operation

4
Examples

• PD/3 at NLR
• Approach
• Demonstrate capacity increase through real-time
  demonstration.
• Validate controller acceptance
• Free Flight of NLR for NASA
• Approach
• early model of pilot cognitive processes
• Then, assess benefits

5
What has changed?

• Many more operational concept options
• More attention to net effect for airlines and
  human society
• Increasing role of analysis fast-time
  simulation
• Economy (Business cases)
• Capacity (TAAM, etc)
• Environment (INM,)
• Human cognition modelling (MIDAS, PUMA, IPME,
  TOPAZ)
• Accident risk (Safety Cases, TOPAZ)

6
Closing the gap

• Real-time simulation feedback to fast-time
• Fast-time simulation and analysis feedback to
  real-time

7
Psychological models

• Information processing models
• Pilot performance (MIDAS, IPME and others)
• ATCo performance (MIDAS and PUMA)
• Human Error Modelling
• Aviation accident investigation
• Hollnagel Control Mode Model

First example Human modelling ? Real-Time

• Recent human cognition models (NASA NLR)
• Hollnagels cognitive control model
• Amalbertis error recovery model
• Situational Awareness error evolution(paper 92
  of ATM 2000 Conference http//atm-seminar-2000.e
  urocontrol.fr/acceptedpapers/index.htm)
• Definition of dedicated real-time experiments in
  SA error evolution
• Economical benefit Systematic approach towards
  real-time simulation of non-nominal situations.

Second example Real-Time ? Safety Cases

• Key problem of safety cases building are the
  unimagineable hazards
• Example French-built oil platform
• After few years French crew replaced by Dutch
  crew
• Productivity down / Errors up
• Hazard headache due to bumping heads against low
  doorways
• New operational concepts Many unimagineable
  hazards in the beginning
• Understanding increases due to human experience
  in real-time simulation
• Economical benefit shortening safety case
  building process

Proposal

• Identify the growing gap
• Identify the range of options to close this gap
• Develop solutions for the two examples mentioned
• Provide economical cost-benefit figures
