Description

Air traffic controllers often work in teams of two, with one person designated as the executive controller (EXE) and the other one as the planner controller (PLN). While being responsible for the provision of ATS in the same volume of airspace, they are performing different (but interconnected) tasks and ultimately, working as a team. This arrangement is somewhat similar to flight crews, however while the pilot in command (PIC) makes the final decision and bears the responsibility for it, controllers are of equal authority (unless otherwise stated in the local procedures).
