An evaluation of task load distribution between en route sector team positions using human performance modeling

A methodology is described to evaluate en route controller task load distribution between the radar and radar associate positions. Detailed controller task analyses are used to construct a human performance model in a discrete event simulation framework to provide task load predictions. The predictions compare current controller roles and responsibilities with a candidate concept in which the radar associate position assumes some responsibility for handoffs and separation. Results indicate that task load can be more evenly distributed among the sector team.
