    m) KL ATSC Duty Shift System for Air Traffic Controllers

    ii) Operations in Restricted/Collapsed Mode

    (1) From 1600 UTC [0000 MYT] until 2200 UTC [0600 MYT] the number of Controllers in the KL ATSC was scaled down by half to enable the Controllers to take a scheduled break from duty:

    • the first group from 1600 UTC [0000 MYT] to 1900 UTC [0300 MYT] and
    • the second group from 1900 UTC [0300 MYT] to 2200 UTC [0600 MYT].

    This practice had been approved by DCA. According to DCA, the scale-down of personnel during lean hours is a norm in air traffic control centres all around the world where air traffic services can continue safely.
