13. THE ROLE OF CONTROL TOWER ● The control tower as the most important facility for air control is equipped with communication intelligence systems. ● All sorts of facilities such as control facilities play the most significant role for the safety of aircraft and passengers ● Without ATCT functions, we can’t do start up and commissioning the whole NBIA integrated system as airport operational readiness ● ATCT progress delay impacts directly opening date of NBIA
