ANSWER
Minister of State in the Ministry of CIVIL AVIATION (Shri Murlidhar Mohol)
(a): When the visibility drops below 800m or Runway Visual Range (RVR) drops below 550m, the
CAT II/CAT Ill operations are commenced at the airports as per applicable standards. Presently, more
than sixty operational airports in the country are equipped with Instrument Landing System (ILS).
Among these, six airports namely, Delhi, Lucknow, Jaipur, Amritsar, Kolkata, and Bengaluru, have
one or more runways certified by Directorate General of Civil Aviation (DGCA) for CAT III
operations.
(b): As per the guidelines issued by the Directorate General of Civil Aviation (DGCA), aircraft
deployed by airlines for CAT II/III operations are required to be equipped with certified autoland
capability with required redundancy, have current maintenance status and serviceability records, and
be fitted with required equipment including dual autopilots and fail-operational systems.
(c): As per the information received from airlines, the adequate number of pilots trained for CAT II/III
operations are available as per the requirement. The deployment of Air Traffic Control Officers
(ATCOs) is undertaken by Airports Authority of India based on the DGCA - Civil Aviation
Requirements (CAR) on Watch Duty Time Limitations (WDTL) which is as per international norms
and also as per air traffic volume at airports so as to ensure safe and efficient air traffic management.
In accordance with the Ground Handling Services Regulations of 2018, all domestic scheduled airline
operators are authorized to undertake ground handling activities through self-handling or by engaging
third-party agencies. The responsibility for deploying adequate and trained personnel to perform
ground handling services rests with the respective agency.(d): DGCA has issued General Safety Circular No. 03/2025, titled "A Comprehensive Framework for
Fog Preparedness, All-Weather Operations and Passenger Facilitation." Before the onset of fog every
year, the DGCA convenes meetings with aviation stakeholders such as airline operators, aerodrome
operators, and other Government organisations, including the Bureau of Civil Aviation Security
(BCAS), the Airports Authority of India (AAI), the India Meteorological Department (IMD), and the
Indian Air Force (IAF), to review preparedness for the conduct of low-visibility operations. The
DGCA also issues guidelines to ensure safe and smooth operations during the winter season.
