Objective
EMERALD RTD the ASAS VF

• To compare the EMERALD RTD Plan against the MAEVA
  Validation Framework to determine the nature of
  validation exercises necessary to deliver the plan

4
EMERALD RTD the ASAS VF

• What is the EMERALD RTD Plan?

5
RTD Plan for ASAS applications
EMERALD RTD the ASAS VF

• Identification of the RTD issues
• Identification of RTD domains
• Operational concepts
• Benefits constraints
• Safety Assessment
• ASAS operations and human factors
• ASAS design and airborne functions
• Transition issues

6
RTD Plan for ASAS applications
EMERALD RTD the ASAS VF

• User requirements or concept phase
• User requirement analysis or feasibility phase
• Functional requirements or acceptability phase
• ASAS development or prototyping phase
• Experimentation or validation phase
• Implementation phase (not part of the RTD plan)

7
User requirements (or concept phase)
EMERALD RTD the ASAS VF

• The concept of Co-operative Air Traffic Control
  needs to be investigated in more detail
• There is a need for operational requirements for
  ASAS applications based on expected benefits (and
  constraints)

8
User requirement analysis (or feasibility phase)
EMERALD RTD the ASAS VF

• Select ASAS applications for European needs
• Conduct an initial cost/benefit analysis
• Define operational scenarios
• Define ASAS requirements for the ADS-B media
• Define an airborne architecture for ASAS and
  airborne functions
• Conduct initial safety studies

9
Functional requirements (or acceptability phase)
EMERALD RTD the ASAS VF

• Define operational procedures for the selected
  ASAS applications
• Define the new Rules of the Air and the
  airborne separation minima
• Conduct a pass/fail, cost/benefit analysis
• Address the transition issues suitable rate of
  equipage, impact upon aircraft operators and ATM
  organisations

10
ASAS development (or prototyping phase)
EMERALD RTD the ASAS VF

• Develop prototypes for ASAS equipment and for the
  new ground system functions
• Conduct off-line simulations for the evaluation
  of ASAS algorithms and compatibility with ACAS
• Develop real-time mock-ups
• Draft industry standards
• Prepare initial training programmes for pilots
  and controllers

11
Experimentation (or validation phase)
EMERALD RTD the ASAS VF

• Conduct real-time simulations involving pilots
  and controllers
• Conduct flight trials
• Measure the potential benefits and constraints
  through a validation process
• Re-evaluate the cost/benefit analysis
• Conduct an in-depth safety study
• Finalise ICAO standards and industry standards

12
EMERALD RTD the ASAS VF

• How does the RTD Plan Map onto the Validation
  Activities?

13
Validation Activities and the RTD Plan
EMERALD RTD the ASAS VF

• RTD plan issues equate to Validation aims of
  MAEVA
• In some cases experiment techniques are specified
• Cost/benefit (efficiency) issues
• Architecture and algorithm issues
• Some examples follow.

14
Measure potential benefits constraints through
real-time simulations
15
Validate ASAS algorithms through real-time
simulations
16
Validate the new share of responsibility between
pilots and controllers
17
Conclusions
EMERALD RTD the ASAS VF

• The ASAS VF maps well to the high-level
  activities defined in the RTD plan.
• Many issues in the RTD Plan are outside the
  validation scope.
• Some issues in the RTD plan need further
  definition leading to high-level VF objectives
• Key issue is complete specification of the ASAS
  applications to be validated
