A Study of Traffic Capacity Index for Air Traffic Flow Management
Midori SUMIYA Sachiko FUKUSHIMA Yutaka FUKUDA
Abstract
ATFM（Air Traffic Flow Management）is conducted to respond demand for traffic increase and to keep safe
and efficient flight at each sector. ATFM use “Traffic Capacity Index” that represents a controller workload to
make a decision of ATFM control. In order to know this index， air traffic controller's task must be measured，
analyzed and classified of each aircraft in each sector to obtain parameter of controller workload. The controller's
task means the consideration of control instructions， the communication with pilot and surveillance. It is time
consuming and laborious to obtain parameter of controller workload.
This paper notes traffic characteristic in each sector and presents a simple new method to calculate this“ Traffic
Capacity Index” instead of current method. The index obtained by current method has been compared with
average number of controlled aircraft in each 15sector at Tokyo Area Control Center. The result has shown that
the index by current method is proportional to average number of controlled aircraft per 0 minutes and its
proportion coefficient corresponds to the average parameter of controller workload.
Then this paper proposed a method by number of proximity aircraft and parameter “K” at each sector to
calculate “Traffic Capacity Index”. The close relationship between the index by proposed method and the index
by current method has been shown. If the number of arriving aircraft is fewer than the average of all sector， this
parameter“ K” can be expressed by a simple function in terms of average number of controlled aircraft.
