The One

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.

During the past two years the commercial airline operators and the travelling public alike have been forced to acknowledge the rapid increase in airport congestion. This problem is most marked in the North Eastern area of America at the present time but a similar situation will develop fairly soon at major airports in Europe. Even with the introduction of the airbus to scheduled services, the number of aircraft movements at conventional airports, within a given time period, will reach a maximum safe level. The restrictions are imposed partly by the large number of aircraft operations on each runway, and partly by Air Traffic Control safety limits.

North Atlantic Area

The North Atlantic is increasingly developing into the main trade route of the age. Shipping, the pioneer along this highway of commerce, in the past decade has been joined by air traffic displaying a striking growth rate. Not only is the number of aircraft simultaneously plying the Atlantic routes constantly on the increase, but also the volume of passengers and freight transported on each flight. The question, whether such flow of traffic in the air and on water could be dealt with in future with the safety to which it is entitled, has led to world-wide discussions over the past few years concerning the necessity for an air traffic surveillance system for the North Atlantic area. A further question, whether one should not include also sea traffic in such a system suggested itself. The initiative for holding such discussions naturally proceeded less from air and shipping undertakings, but rather from those committees who are entrusted in supervising the safety in the conduct of man and merchandise.

Hong Kong is situated at the center of the air traffic axis for Asia, and has, at Kai Tak, one of the busiest airports in the world. The areahas experienced a ten-fold increase in population over 25 years and now has the highest urban density in Asia. Hong Kong is in the monsoon belt and is subjected to the very severe weather conditions of typhoons.Kai Tak airport is unique. The main 7,000 foot runway is substantially reclaimed from the harbor which in turn lies within a spectacular mountain bowl. The 310° flight path traverses the north end of the Kowloon peninsula with equally spectacular urban development.Overall disaster contingency planning within this broad spectrum is the responsibility of a joint Police/Military Command. An Aircraft Accident Committee coordinates joint emergency service planning, command and communications training and exercises.Response to an aircraft disaster is initated by Air Traffic Control through the joint Fire Service/Police/Military Command which sets up a discretionary response for intervention, search and rescue by land, sea and air.Although the problems are universal, the Maximum Credible Incident scale is extraordinary to Hong Kong. Unique means of dealing with this problem have been specially evolved here, particularly in the field of fire fighting and marine rescue which involve a Catamaran Rescue and Immediate Care Vessel.

This paper considers the issue of operating aircraft through the North Atlantic's Minimum Navigation Performance Specification (MNPS) airspace. Noting that aircraft constantly strive for reduced fuel burn and uplift, it describes how flight operators and pilots conduct safe, efficient flights through the region. Reference is made to mechanisms of the North Atlantic MNPS airspace in terms of its Organized Track Structure and other routes that exist. These different structures emphasize the level of flexibility available. Flight planning procedures and requirements necessary to obtain oceanic Air Traffic Control (ATC) clearances are mentioned, as is an account of how communication and position reporting procedures operate to apply the Mach Number technique. Other aspects of MNPS operations such as ETOPS operational restrictions, meteorological effects, the employment of Reduced Vertical Separation Minima and planned regional changes aim to provide an overview of the MNPS system's current and future air traffic management.

A multi-factor linear regression model was developed to describe and estimatepilot-controller voice communication loads. The routinely-recorded air traffic control data andassociated voice communication data were collected to statistically analyze the correlation betweencomplexity factors and pilot-controller voice communication loads. Results show that each complexity factor is significantly correlated with voice communication loads. To eliminate multicollinearity among complexity indicators, principle component analysis is performed to extract two principle components from complexity indicators. These variables were used to construct the multivariate regression equations of the communication durations, the communication frequencies, and the integrated voice communication load index. These equations can quantitatively describe and estimate air traffic controller’s voice communication loads.
