SMART AIR TRAFFIC MANAGEMENT SYSTEM

INTRODUCTION FEASIBILITY DESIGN TOOL ARCHITECTURE FOR ATMS SMART AIRCRAFT CONCLUSION

HYBRID SYSTEMDISCRETE AND CONTINOUS EVENTS DISCRETE EVENT SYSTEM MODELS THE CO-ORDINATION AMONG AICRAFT DIFFERENTIAL EQUATIONS MODELS THE AIRCRAFT DYNAMICS

CURRENT ATMS WILL NOT ABLE TO HANDLE EFFICIENTELY INCREASE IN AIR TRAFFIC CONCEPT OF FREE FLIGHT PILOT TO CHOSE ROUTES, ALTITUDE, SPEED AND TO SELF OPTIMISE AUTOMATED CONFLICT RESOLUTION IN WHICH A/C WILL CO-ORDINATE TO RESOLVE CONFLICT

FEASIBILITY- HELP FROM EXISTING GLOBAL POSITIONING SYSTEM, AUTOMATIC DEPENDENCE SURVEILLANCE BROADCAST, TRAFFIC ALERT AND COLLISION AVOIDANCE SYSTEM AND POWERFUL ON-BOARD COMPUTATION IN FUTURE AIRCRAFTS INCONFLICT CO-ORDINATE AMONG EACHOTHER AND ATC IN ORDER TO PREDICT AND RESOLVE CONFLICT

DESIGN TOOLEXISTING ATMS MODELLING TOOLS AND SIMULATION DONOT ADRESS THE HYBRID ISSUES OF THE PROBLEM IN DEVELOPMENT OF SMART ATMS THE DESIGN TOOL SHOULD BE ABLE TO MODEL AND SIMULATE FACILITIES FOR ATMS IN CONTEXT OF HYBRID SYSTEM. SHIFT ----- DEVELOPED BY PATH PROJECT (BERKELEY) OMALA ----- DEVELOPED BY LUND UNIVERSITY(SWEDEN) SHIFT ALLOWS USERS TO CREATE THERE OWN FUTURE ATMS BY COMPOSING OBJECTS FROM AVAILABLE LIBRARIES AND CAMPARE CURRENT AND FUTURE ALTERNATIVES

ARCHITECTURE FOR ATMS-- TRACON-2 AUTOMATIC CONFLICT RESOLUTION TRACON-1

TRACON—TERMINAL RADAR APPROACH AND CONTROL RANGE – 50 NM, 11000 ft. DUE TO HEAVY TRAFFIC WITHIN –TRACON– AIRCRAFT TRAVELS ALONG PREDETERMINED , OPTIMAL APPROACH AND DEPARTURE ROUTES. BETWEEN –TRACON– TO—TRACON– AIRCRAFT ENJOYS FREE FLIGHT AND FLY OPTIMUM TRAJECTORY AND ALSO AVOID HAZARDEROUS WEATHER REGION. OUTSIDE –TRACON – REGION AIRCRAFT FLY UNDER SUPERVISION OF CENTRES AND CO-ORDINATE AMONG EACH OTHER TO RESOLVE CONFLICT.

AIRSPACE STRUCTURE CURRENT – WAYPOINT ARE FIXED(VOR) -- THERE IS RIGID JETWAY IN SKY , AIRCRAFT ARE NOOT EQUIPED WITH NAVIGATIONAL TOOLS ( Ex- GPS) ASSUME—WAY POINT ONLY IN - TRACON—AREA DUE TO HEAVY TRAFFIC. NO SRUCTURE IN AIRSPACE OUTSIDE ---TRACONS. AREA OUTSIDE –TRACON –IS CONSIDER AS FREEFLIGHT OR CENTRE AIRSPACE.

AIR TRAFFIC AND CENRAL CONTROLLER HUMAN CONTROLLER IN –TRACON– AND CENTRAL AIR SPACE. BUT A/C HAS MORE FREEDOM IN CENTRAL AIR SPACE. ATC PASSE SEQUENCE OF WAY POINT TO STRATEGIC PLANNER ON BOARD A/C WHICH WILL SEQUENCE APPROACHING A/C FROM ENTRY GATES OF THE –TRACON– TO LANDING APPROACH. ATC HAS KINEMATICS OF AIRCRAFTS , WIND DIRECTION , MAGNITUDE RUNWAY CONFIGRATION etc AND SHARES IT WITH FVMS ON BOARD THE AIRCRAFT. IT SUGGEST ARRIVAL SCHEDULE AT DESTINARION AIRPORT. ALSO ANNOUNCES ARRIVAL TIME AND REFLECT CONFLOCTS.

STRAGETIC PLANNER ON BOARD FVMS -- DESIGN A COARSE SELF OPTIMAL TRAJECTORY BY INFORMATION AVAIALBLE (FEUL , TIME , EXPLOTIATION OF FAVOURABLE WINDS ) --RESOLVE CONFLICT BETWEEN A/C IN CENTER AIRSPACE. STRAGETIC PLANNER OF ALL A/C INVOLVED IN CONFLICT DETERMINE A SEQUENC OF MANEUVERS WHICH RESULTS IN A CONFLICT FREE OPTMIUM TRAJECTORIES EITHER USING COMMICATION WITH EACH OTHER OR VIA SATTELLITE. --IT COMMANDS ITS TACTICAL PLANNER

TACTICAL PLANNER --IT REFINES STRAGETIC PLANNER BY INTERPOLAING CONTROL INPUT AND GIVES SMMOTH TRAJECTORY --IT COMMAND TRAJECTORY PLANNER

TRAJECTORY PLANNER -- USES DYNAMICS MODEL OF THE AIRCRAFT. -- IT HAS SENSORY INPUT ABOUT WINDS MAGNITUDE AND DIRECTION TO DESIGN TRAJECTORY FOR A/C. -- IT GIVES SEQUENCES OF FLIGHT MODES NECESSARY TO EXECUTE THE DYNAMICS PLAN. -- IT PASSES REQUIRED INFORMATION TO REGULATION LAYER.

REGULATION LAYER-- -- ONCE FEASIBLE DYNAMIC TRAJECTORY HAS BEEN DETERMINED THIS LAYER TRACKS IT. -- DUE TO LARGE EXTERNAL DISTRUBANCES (WIND OR MALFUNCTIONS) TRACKING IS SEVERLY DETERIORTED. -- REGULATION LAYER HAS ACCES TO SENSOR INFORMATIONS ABIOUT ACTUAL STATE OF A/C DYNAMICS AND THUS CALCULATES TRACKING ERROR -- IT PASSES TRACKING ERROR TO TRAJECTORY PLANNER TO FACILITATE REPLANNING IF NECESSARY /.

FUNCTIONAL DECOMPOSITON OF ATMS-IT CAN BE DIVIDED INTO FIVE MAJOR PART ---- AIRSPACE --AIRCRAFT --AIR TRAFFIC CONTROL -- WEATHER -- PERFORMANCE MONITORS

( 1 ) STRUCTURE OF AIRSPACE DIVDES THE SKY INTO DIFFERENT REGIONS--- TRACONS AIRSPACE ( VOR POINTS, AIRPORT ). --CENTRAL AIR SPACE (VOR OR UNSTRUCTURED IN FREE FLIGHT ). --SUA (SPECIAL USER AIRSPACE). ( 2 ) AIRCRAFT– MODELS OF EACH AIRCRAFT. -- DYNAMICS. -- CONTROLLER ( FVMS OR PILOT COMMAND ). -- SENSOR ( NAVIGATION , SURVIELLANCE ). -- COMMINICATION ( INFO EXCHAGE BETn A/C AND ATC , AMONG A/C ).

( 3 ) AIR TRAFFIC CONTROL ---- HUMAN CONTROLLER AT – TRACON– AND CENTRE AIRSPACE. -- MAINTAINS SAFE SAPERATION BETWWEN AIRCRAFTS. -- INFORMATION IS SHARED BETWEEN – TRACON -- , CENTRAL AIRSPACE. ( 4 ) WEATHER--- WIND PROFILES , VISIBILITY CONDITIONS, CURRENT OR DEVELOPING STROMS , POSSIBILITY OF ICY RUNWAY CONDITIONS

( 5 ) PERFORMANCE MONITOR— -SAFETY, EFFICIENCES , COMFORT , CAPACITY AND -HUMAN FACTOR. ATMS DYNAMICS AIRCRAFT CONTROLS SENSORS AIRSPACE ATC WEATHER MONITOR COMMN TRACON CENTRE

CONCLUSION SMART ATMS IS A UNIFIED MODELLING AND SIMULATION FRAME WORK FOR ATMS DUE TO HYBRID NATURE OF SMART – ATMS IT CAN CREATE ITS OWN VERSION OF ATMS AND COMPARE CURRENT AND ALTERNATIVE FUTURE CONCEPT.
