In this case RPL will ensure that there is 1 “Mps”, 1 “Mts”, etc, on every day. All changed shifts are marked blue. In case the number differs from required setting, there will be a message on the date line. Notice that sector leaders are different from supervisors. A supervisor is in charge of a control center (ACC) or a tower (TWR) and he is typically defined by the rating letter “s” in character position 2 (e.g. “Ms”). A sector leader is in charge of a smaller ATC unit, like west sectors, upper sectors, or approch sectors and he is typically defined by also letter “s”, but in position 3 (e.g “Mps”). Therefore the letter “s” in position is a reserved letter (like the “j” is used to identify OJT shifts). The sector leader function is normally used in larger ATC’s with supervisors in a separate roster. If you prepare rosters with supervisors and sector leaders, the supervisor rating must be changed to “S”.
