<mods:abstract>The SESAR programme aims at developing the future European air traffic management&#xd;
system. It focuses on four keys areas: capacity, safety, efficiency and environment. In view&#xd;
of the expected growth in air traffic demand in the coming years, the current goal is to&#xd;
increase the airspace capacity, which is already close to saturation in many cases.&#xd;
Currently, the separation standards applied in a given volume of airspace are fixed, both&#xd;
horizontally and vertically, which means that in many cases this is one of the determining&#xd;
factors of capacity. Separation management is an area where improvement is sought, in&#xd;
particular through the application of new operational concepts (separation modes) which&#xd;
include the redefinition of aircraft separation minima. One of the solutions to be&#xd;
investigated is the variable (Ad Hoc) separation proposal put forward by SESAR.&#xd;
This future concept implies a change in the application of separation minima from the&#xd;
current fixed standards to a new variable approach. With this new concept, ATCo (Air&#xd;
Traffic Controller) would separate aircraft by applying different separation minima in the&#xd;
same volume of airspace. These separation values are tactically determined for each&#xd;
particular aircraft pair (Ad Hoc) depending on a number of factors: aircraft categories,&#xd;
encounter geometry, atmospheric conditions, etc.&#xd;
Applying different separation minima in the same volume of airspace implies a substantial&#xd;
change in some of the ATC activities. Also, new functionalities in ATC support tools are&#xd;
needed. This study presents the Ad Hoc separation operational concept and provides the&#xd;
basis for the development of the algorithm for calculating variable separation minima.</mods:abstract>
