The India Meteorology Department (IMD) has indigenously developed Drishti, an instrument that will provide real time visibility information to pilots.
The instrument will help pilots in quick decision-making during critical landings and take-offs of aircraft particularly during foggy or rainy days.
Key Points
Drishti has been developed by the surface instruments division of IMD based in Pune, Maharashtra.
The system transfer the crucial visibility updates to the pilots in real time who can now use this information that will be updated every minute.
Drishti is a transmissometer that takes in account the real time weather parameters like humidity, wind speed, temperature conditions, etc., along the runway in order to calculate the visibility distance offered at that particular runway.
Generally, due to the poor visibility, the aircraft operations would often get disturbed that affects passenger traffic during winter and monsoon seasons especially in Northern India.
The first Dristi instrument was installed at the Indira Gandhi International Airport in New Delhi in 2015 on a trial basis.
