Abstract. The paper examines the workload perceived by air traffic control officers (ATCOs) and pilots during continuous descent operations (CDOs), applying closed- and open-path procedures. CDOs reduce fuel consumption and noise emissions. Therefore, they are supported by airports as well as airlines. However, their use often depends on pilots asking for CDOs and controllers giving approval and directions. An adapted NASA Total Load Index (TLX) was used to measure the workload perception of ATCOs and pilots when applying CDOs at selected European airports. The main finding is that ATCOs’ workload increased when giving both closed- and open-path CDOs, which may have a negative impact on their willingness to apply CDOs. The main problem reported by pilots was insufficient distance-to-go information provided by ATCOs. The workload change is important when considering the use of CDOs.

Traffic Control System

The present national Air Traffic Control system is a ground-centralized, man intensive system which through design allows relatively little meaningful pilot participation in decision making. The negative impact of this existing design can be measured in delays, dollars and lives. The FAA's design plans for the future ATC system will result in an even more intensive ground-centralized system with even further reduction of pilot decision making participation. In addition, controllers will also be removed from on-line decision making through anticipated automation of some or all of this critical function. Recent congressional hearings indicate that neither pilots nor controllers are happy or sanguine regarding the FAA's design for the future ATC system.

Actual Position

As a general rule the navigational function is aimed at determining the position of the aircraft in order to resolve three types of problem:(1) To subject the aircraft's flight path to an optimum trajectory calculated before departure or progressively adapted in course of flight to the circumstances encountered.(2) To choose at each point of the selected flight path the flight system best adapted to the safety and economy of the flight.(3) Taking into account the presence of other aircraft in the airspace, to know and make known the actual position and the information allowing provision to be made for future positions, so as to permit effective air traffic control.Departures of the actual from the chosen flight path penalize the flight by a lowering of economy (in flying time or fuel consumption). It does not seem, however, that the problems raised from this point of view by S.S.T. are by nature or in difficulty any different from those which affect conventional aircraft. Taking into account the present-day precision of navigational aids there is every reason to believe that departures of the actual flight path from the optimum flight path will introduce a penalization which it is possible to ignore when compared with the penalization due to the inaccuracy of the knowledge of the elements (winds, temperatures, pressures) which have, in fact, served to determine this optimum flight path.

Analysis of the problem of implementation of automated air traffic control systems showed that automation in aviation began to be used primarily to solve navigation problems and control various systems. The widespread introduction of computer-aided automation in ground-based air traffic control systems has freed air traffic controllers and air traffic controllers from time-consuming computational operations and made it possible to automate a number of complex tasks and thus significantly increase flight safety. Further development of aviation equipment, information technology, radio navigation and surveillance requires a rapid solution of complex problems with high accuracy, which necessitated the improvement of existing and creation of fundamentally new technical means that meet the requirements of modern aviation and international air traffic regulations. Such technical means include EGNOS systems. The study of the proposed location for the EGNOS RIMS station at the Kyiv International Airport (Zhulyany) was carried out. Thanks to the fruitful support of the DCA provided by the GSA contractor ThalesAleniaSpace, the study helped to gather the necessary data to work offline. This offline processing is complete and issues have been identified. The interference that has been selected affects the location. One of the key criteria for site selection is the radio frequency (RF) environment, as environmental conditions have a direct negative impact on the performance of the EGNOS system. It turns out that the measurements carried out during the study highlighted the sources of interference, the power of which exceeds the required level in the used frequency bands GPS L1 and L2. as these interferences will adversely affect the performance of the EGNOS RIMS receiver. One way to restore compliance is to study these interference sources and remove them if possible. On the other hand, the proposed location at Kyiv International Airport (Zhulyany) provides a promising level of compliance for life safety services.

Abstract. Owing to the different approaches for remote tower operation, a standardized set of indicators is needed to evaluate the technical implementations at a task performance level. One of the most influential factors for air traffic control is weather. This article describes the influence of weather metrics on remote tower operations and how to validate them against each other. Weather metrics are essential to the evaluation of different remote controller working positions. Therefore, weather metrics were identified as part of a validation at the Erfurt-Weimar Airport. Air traffic control officers observed weather events at the tower control working position and the remote control working position. The eight participating air traffic control officers answered time-synchronized questionnaires at both workplaces. The questionnaires addressed operationally relevant weather events in the aerodrome. The validation experiment targeted the air traffic control officer’s ability to categorize and judge the same weather event at different workplaces. The results show the potential of standardized indicators for the evaluation of performance and the importance of weather metrics in relation to other evaluation metrics.
