Summary:
With the two ADS-Bs on Myanmarese islands now providing live data to area controllers in Kolkata, the safety of flights will increase. The timelag means controllers can’t see the present position of flights and issue necessary safety instruction. To overcome this, they increased the separation between flights to eight times the normal distance as a measure of abundant caution.“In the 18 lakh sq km of airspace under Kolkata flight information region (FIR), 3.5 lakh sq km is oceanic. That has halved now, an enormous confidence-booster to both controllers and pilots,” a senior controller explained. The Automatic Dependence Surveillance-Contract (ADS-C) provides coverage but it is inadequate as the aircraft position is transmitted every 8 minutes and not live..
