FAAEurocontrol TIM9 - ATMCP-RTSP
ICAO – ATMCP ATM operational Concept Panel
Operational concept First version available – will be sent to States for
consultation
What could be Required Total System Performance
(RTSP) ? “Define and study the feasibility of RTSP, clearly
identifying its role and functionality in the future global
ATM system, in the context of the ATM operational
concept”

ATM community expectations Adequate performance levels for
Safety Capacity Access and Equity Efficiency Flexibility Predictability Global Interoperability Cost Effectiveness Environment Participation by the ATM Community Security
Other operational requirements of the airspace users

ATM system performance
Key to
Understand expectations
Detect need for change
Get acceptance and confidence that the proposed
concept will satisfy expectations
Get decisions on projects
Compare achievements & expectations

From Expectations to System Performance
General description vs objective way to measure Measurement
actual, to be achieved present, forecast, contextual trade-offs except safety “SMART” metrics Issues: global/regional/local targets?
Numerical figures?
Perception External (outcome) Vs internal (output) RASP Vs RTSP

RASP & RTSP definitions Required ATM system performance (RASP)
RASP is the set of criteria, expressed in the form of performance parameters, and values of these parameters, that the ATM system needs to meet with a given probability, in order to support the approved quality of service specified for a particular environment.
Required total system performance (RTSP) RTSP is the aggregate of criteria, expressed in the form of
performance parameters (operational and technical), that the ATM system needs to meet in order to deliver the approved quality of service and RASP specified for a particular environment.

RTSP in a given airspace Defined for most demanding characteristics Driven by most stringent requirement
likely: conflict management and navigation (real-time, safety related decisions)
Dependent on available solutions Expressed as combination of component
requirements A minimum set to satisfy expectations Adapted to local and user needs Nominal & degraded modes considered

Essence-Causal Model
Where is coming the performance from ?
What is the Impact of change on performance ?
What are the commands/levers to achieve
the expectations ?

Further work of ATMCP Next step
To validate the initial ideas To give some reality to the abstract model How useful it is ?
We need your contribution.

The Performance Loop
« What we can’t measure, we can’t improve »
« To understand the Present, to prepare the Future »
To measure the system, to fix target, to propose and validate changes – to implement …
We need to « pilot » the ATM system

My personnal suggested questions to the TIM
Common definitions of the word/concept used for metrics to allow comparison Are part of information management and regulation
Global vs Individual performance ATM network Cooperation between units Cooperation between ATSP
Human performance Variability among persons Variability for one person according to time Criteria for selection Needs for training
