INNOVATIVE RESEARCH

Introduction I

Actual ATC systems are human centred

Technical equipment support the controllersFlight plan data (last update 2 hours prior take off)Sensor data (PSR, SSR, … snapshot of last known situation)Correlation of flight plan and sensor data

Help controller’s to create mental traffic pictureBased on past sensor and flight plan dataTechnical systems have no knowledge of future AC behaviour (feedback from ATC instructions /FMS programming)


INNOVATIVE RESEARCH

Introduction II

Tendency towards stripless ATM systems

Reduced/limited availability flight plan dataIncrease importance of sensor data

Complex representation on ODS2D data on ODS – 3rdD in label

Humans mental resources are one of the bottlenecks of the actual ATM system


INNOVATIVE RESEARCH

Possible future ATM Systems

Towards 4D ATM to increase capacityNew ATM concepts like:

Route offsets4D rendezvous pointsStation keeping of two or more ACDelayed or locally fixed climb/descend orders

AC - FMS supports the 4D navigation

Resulting for the humans: Increase of traffic complexityRequire for the humans:

New working conceptsNew ways of presenting data (reducing complexity)Pre-processing of data (mathematical, logical) to reduce workload


INNOVATIVE RESEARCH

Vital – Table Concept

Innovation Vital:

Digital and analogue representation of the data (FP/sensor)Pre-processing of these data to support humans rough estimations by exact mathematical, logical predictionsPermanently updated and recalculated

Vital presents data in form of a tableEach AC is represented as one line in the tableLines may be freely placed inside of the table

Example: En-route MONitor (EMON)


INNOVATIVE RESEARCH

Vital – AC Artefact

Vital – the artefact line content:Call-sign (indicator for : east-, west-bound, handle to move artefact)Airport of departureAirport of destination Aircraft typeSpeedActual flight level Analogue time-line data (indicator for sector boundary)Exit flight levelExit way point

INNOVATIVE RESEARCH

Vital – Analogue Time-line

Vital represents the flight path of an AC

On a dynamic time-lineUpdated in real-time from actual and extrapolated sensor data with regard to AC performance

INNOVATIVE RESEARCH

Benefits of a Time-line Approach

ATCO roughly estimate AC speed from RadarMentally extrapolate future position of each AC

Poor accuracy require large safety marginsPrediction error for 2…3 minutes ~ acceptablePrediction error for 10…15 minutes ?

Vital - pre-processing of Radar and flight plan dataExtraction of the true AC speed from past positions for Logical mathematical extrapolation of future AC positions

Good accuracy (uncertainty) standard safety marginsPrediction error for 2…3 minutes rather low (similar humans)Prediction error for 10…15 minutes ~ acceptable

(depending on flight steadiness – ATC instruction)Continuously updated


INNOVATIVE RESEARCH

Hypothetical Benefits of an Analogue Time-line

Vital represents the 4D traffic in a clear and simple mannerTraffic visualisation well adapted to humans mental representation and understanding

Supporting humans 4D trajectory prediction Analogue flight path representation for ease human perception Simpler detection and predictability of potential problemsReduced mental workload caused by difficult estimations (future positions)Better understanding of the traffic in a extended timeframe (~20min)

Reduce mental workload – increase SA

Vital will not affect the existing safety level - in a negative sense at least


INNOVATIVE RESEARCH

Vital – Conflict Detection

Detection of conflicts (basic):Opposite traffic (a-b)

Merging traffic (c-d)

Over speeding (b-c)

By vertical comparing of time-lines

INNOVATIVE RESEARCH

Vital – for a future 4D environment

ATM and AC FMS going towards 4D trajectories

4D complexity becomes a challenge for the controllers

Vital reduce complexity by innovative analogue information presentation (benefits - similar analogue/digital watch)

Support of new 4D concepts (offset, station keeping, speed control, 4D rendezvous, …)


INNOVATIVE RESEARCH

Vital – Representing Route Offsets

Flying offset: right or left in parallel to existing route Safe horizontal separation of parallel routes (i.e. 5 NM)
