1To speed up air traffic, additional multiple parallel Air Traffic Services (ATS) routesunder EMARSSH (Europe-Middle East-Asia Route Structure South of Himalayas) project wereintroduced in the year 2002 and the Reduced Vertical Separation Minima (RVSM) in 2003.There has been significant increase in air traffic and the air space utilisatiOn following theintroduction 'of EMARSSH routes and RVSM. This has necessitated an increase in trainedmanpower.In view of the further increase in air traffic anticipated in the coming years the followingadditional measures are required to be taken to further, increase the airspace capacity and flightsafety.(1) Reduced longitudinal separation minima between aircraft both in the en route phase andthe arriving/departing phase of the flight should be provided by application of radar' separation instead' of procedural separatio'n in Indian terrestrial airspace. Forinternational routes, this may be adopted wherever the adjacent country/ATS unit isable to provide similar separation.(2) Bridge the gaps between some of the adjacent radar coverage to cover the entireterrestrial air space. Four additional radars are needed as per the details given in section5.4.3.(3) Radar data networking has to be ensured to provide continuous radar surveillance incontiguous sectors.(4) High Frequency (HF) back-up must be made available to Air Traffic Control Officers(ATCOs) with monitoring and intervention capability.(5) Upgrade air space from, Class D & E to Class A in RVSM air space, i.e., FL (Flight Level)290 to 410.(6) Introduce user preferred routes [direct routing] to reduce flying time and thereby reduceairspace occupancy.(7) .Review the existing number and jurisdictions of various Area Control Centers (ACCs)and sectors therein. (The sectors need to be reorganised and additional sectors are to beprovided in high traffic density area to facilitate efficient handling of traffic and toensure flight safety. Consequently, adequate manpower has to be provided to these areacontrol centers/sectors.)•(8) Create Upper Area Control • between .FL 26o and FL 460 [in view of additional FLsintroduced through RVSM].(9) Implement air traffic flow management system.(1o) Integrate all Radar Data Processing System (RDPS) and Flight Data Processing System(FDPS) in various ACCs interfaced with centralised air traffic flow management system.(11) Introduce advanced computer-aided Controller tools to detect traffic conflicts and24
