The limitations in en-route Air Traffic Control today are generally accepted as being the
workload and performance of the controller. This method of operation is known as the
'manual control process'.
The manual control process is an open loop form of control, that relies heavily on
controller judgement and decision making. Future developments in ATC, that use twoway
datalink, and integrate air and ground systems, are expected to be delayed. This
leaves the manual control process to manage the projected growth in air transport
demand.
An analysis was carried out of the manual control process on two sectors at the London
Area & Terminal Control Centre at West Drayton. Particular attention was given to
understanding complexity, the functions that controllers perform, decision making and
information sources. A systems approach was taken to the analysis and used
multidisciplinary research techniques. The study used naturalistic data collection.
Both the ground and airborne systems were reviewed, and developments found within
them, that can benefit the control process. An analysis of incidents in en-route ATC was
also conducted.
Proposals are made that can support an enhanced control process. These were modelled,
and the results indicated that reductions in controller workload are attainable. The
changes to the control process involve more close control of the vertical plane, and
improved and more precise information being made available to the controller. It is
suggested that aircraft flight management systems are used as a control tool, and system
requirements are proposed. |
