- ATCO's and Pilot proficiency checks are being carried out regularly:
- ATC services are being modernized to include conflict warning in the system to assist ATCO's.
- Coordination procedures of handing over from one unit to another have been laid out. Coordination of handing over traffic to adjoining FIR has been worked out & any deviation is being pointed out to the concerned units for taking corrective action.
- Whenever required, corrective training is being given to Pilots and Air Traffic Controller , and training procedures amended.
- Controllers are given training on ATC simulator at major stations and sensitized on the subject:
- Implementation of  Safety Management  System at airports to mitigate  the risk of accidentl incident.
- Implementation of flexible use of airspace which will reduce traffic congestion in the airspace
- Airlines have been directed to avoid use of similar / confusing call signs.
- One separate Directorate of Air Space and Air traffic Management in DGCA has been created in DGCA for better surveillance and regulatory functions in Air traffic Management (ATM)
- Case studies of Airprox IATC incidents are discussed and analysed to avoid recurrence of such incidents

- Advanced ATM Automation Systems have been implemented at 38 airports in addition to six Metro airports at Kolkata, Delhi, Mumbai, Chennai; Hyderabad and Bengaluru providing the controllers with advanced Safety nets, tools and safety features for enhancing safety and efficiency:
- AAI 21 ADS-B across India for improved surveillance on movement of aircraft in  continental   airspace. Multiple radarsIADS-B data have been integrated at various airports/ ATC Centers which provides enhanced overlapping radar coverage enabling controllers to continuously see aircraft on their display.
- Eight number of Advance Surface Movement Guidance and Control System (A-SMGCS) are already operational at Delhi, Mumbai,  Kolkata, Chennai; Bengaluru, Hyderabad, Lucknow and Jaipur Airports and are under installation at Guwahati; Ahmedabad and Amritsar. A-SMGCS helps the air traffic controllers for better situational awareness of traffic on ground at the airport and helps them in prevention of any mishap at the airport
- Automatic Dependent Surveillance Contract (ADS-C) have been provided at Mumbai, Kolkata; Chennai and Delhi for surveilance on aircraft flying over oceaniclremote airspace which helps ATCs in maintaining better situational awareness of traffic and prevention of conflict situations. Similarly Controller Pilot Data Link Communication (CPDLC) have been provided at these four airports for having digital communication with aircraft flying over oceaniclremote airspace.
- Data Link Communication System that helps in eliminating human errors and ensures enhanced safety and efficiency of operations are being used for issuing pre-departure clearance to aircraft via Data Link at 6 airports namely Delhi;, Mumbai; Kolkata, Chennai; Hyderabad and Bangalore.
- Air Traffic Flow Management System has been introduced on trial basis to balance demand and capacity of air traffic:
- Bengaluru; Hyderabad and Ahmedabad) which are being used for imparting training to ATCs on traffic conflict management; emergency and unusual occurrence handlings.
- To enhance safety of aircraft operations, the upper  airspace harmonization has been implemented at Chennai and Kolkata. Upper airspace harmonization of Delhi and Mumbai is planned.
- Flexible use of airspace between civil and Defence airspace is introduced to reduce traffic congestion in the Indian airspace.
