a blip-driver (sometimes known as a pseudo-pilot) sits at the other end of the radio from a trainee controller pretending to be the pilots, manipulating the simulated aircraft the controller is working on radar or VCR before being set lose on the real ones. It probably doesn't have a long-term prospect in HIAL, but in NATS such jobs often lead to other positions and many ATCOs, ATSAs, simulator specialists and others started out there.
