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”

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

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
