Aircraft Navigation

The navigational problems presented by supersonic aircraft do not differ essentially from those with modern four-jet aircraft. Navigation will still entail three main tasks:i. To ensure that the crew knows the position of the aircraft at any given moment, within a reasonable time, and with the necessary accuracy.ii. To ensure that the aircraft is operated under the best conditions of route, speed and height for profitable operation.iii. To ensure compliance with air traffic control.

The Relationship

Progressive changes in the relationship of aircraft navigation and Air Traffic Control have produced a disturbing discrepancy between terrain clearance theory and practice. In theory, terrain clearance is assured by the aircraft adhering to certain specific and well-known traditional techniques; but in practice these are now often allowed to go by default, due to pressure of the A.T.C. environment. The purpose of this paper is to illuminate the exact nature of the problem and to suggest that clarification is overdue.

In this paper M. Villiers, Ingénieur en Chef de la navigation aerienne, and M. de Barbeyrac, of the Société d'Etudes des Systèmes d'Automation, discuss the application of a satellite monitoring system to A.T.C. procedures.The paper first discusses control of lateral separation under the headings of present navigation accuracy over the North Atlantic and by a satellite monitoring system. It goes on to discuss control of longitudinal separation with and without monitoring, and finally discusses intervention procedures and aids.The writers conclude that it is possible with a mathematical model to establish a general relationship between the performance of aircraft navigation systems and a monitoring system on the one hand, and the lateral and longitudinal separation of aircraft and the mode of A.T.C. action on the other. From this relationship the number of A.T.C. interventions can be computed and it appears that the reduction of separations resulting from a satellite monitoring system will fit such a system to the forecast air traffic beyond 1975. In addition, the requirement for voice communication, specific to A.T.C., would be extremely limited. The paper was presented to the S.S.T. Working Group, sponsored jointly by the French, German and British Institutes of Navigation.

And Control

In the design and analysis of air traffic control systems the considerations which lead to the adoption of a particular route and control structure in a given airspace are partially governed by the traffic demands between given points within the area concerned. When air traffic control plans are being developed for use in a particular area, it is of prime importance to know where the main A.T.C. problems lie and to concentrate planning effort in these parts of the system. The development of routing and control procedures should take into account the degree of risk associated with any particular route structure. In the case of near mid-air collisions (NMAC's) or collisions, quantitative prediction of the risk involved is difficult. In this paper a simple theoretical method for predicting the number of NMAC's for a particular route structure is given. Such a method has been used practically for determining the amount of control required for a particular off-airways area and to help determine the optimum control procedures for air traffic planning in that area.

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.

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.
