Strategies in Controlling, Coordinating and Adapting Performance in Air Traffic Control: Modelling 'Loss of Control' Events

This paper discusses how the continued growth of civil aviation and the introduction of new air traffic management systems have increased the complexity of the system and this has required more adaptable patterns of control and coordination. The paper shows how there is a need to look into the patterns of control, the transfer of control and coordination across boundaries or sectors and the adaptation to unexpected scenarios that may contribute to 'loss of control' events. The paper elaborates on the extended control model and complements a functional description of the air traffic control (ATC) system with several strategies that require 'being in control' of the joint cognitive system. Reviews of the literature, field studies and observations of performance in ATC have been used to model 'loss of control' events. The paper shows how adapting control strategies in order to: (1) maintain control of actions; (2) transfer control; (3) coordinate; and (4) choose new modes of functioning and recovery when control breaks down. These control aspects are useful for debriefing controllers after critical events. These controls also identify system performance flaws that can provide input to ergonomic interventions, such as the design of new air traffic management systems, decision aids and role allocation.
