ft actually taken to a control.
- amount of aircraft; - average time of flight of aircraft in air traffic area;
Density of air traffic - amount of aircraft, that are in 1 unit of volume of air traffic control zone.
; ;
Load of zone - amount of aircraft that are under control in the limits of given zone simultaneously.
Coefficient of load of zone:
- throughput.
Throughput of air traffic zone - amount of aircraft that can be serviced by air traffic control units of this zone in 1 unit of time with adherence of normative indications of safety of flights.
Throughput of air traffic controller - amount of aircraft that can be under control of air traffic controller in 1 unit of time taking into account direct procedures of control simultaneously.
Work load of air traffic controller - time needed to perform necessary technological procedures of air traffic control.
Factors that influence on commitment:
intensity of flights;
density of flights;
structure of zone (size, amount of routes, amount of points of intersection of routes)
characteristics of aircraft flows (directions of flows, relations of types of aircraft in flows) equipment of work place
air traffic management (features of work technology, amount of air traffic controllers in 1 zone, character of restrictions in airspace)
level of air traffic controller
work place management
regim of work and rest
character of work place environment
psychological and psycho-physical characteristics of air traffic controller
Coefficient of work load of air traffic controller is expressed by relation of time spent by air traffic controller to perform technological procedures and total resource of time.
- is obtained only when we can calculate the time of operations. Coefficient of work load of air traffic controller has to be placed in the limits ftom 0.2 to 0.85, normative coefficient is 0.55. Relation between commitment coefficient and main characteristics of flow of aircraft is expressed by following equation:
- time spent on voice communication during aircraft aperations (ex .: climbing, descending)
- time spent on giving of instructions to change FL, direction of flight, conflict situation, conditions of flight.
- time spent on information exchange between neighbour controllers, air traffic coordination, work with strips and equipment of air traffic control system.
