INTRODUCTION<\/strong><\/p>\n

The collision risk models (CRMs) covered in this circular are
\nthose presented in the Manual on Airspace Planning Methodology
\nfor the Determination of Separation Minima<\/em> (Doc 9689) and the
\nManual on Implementation of a 300 m (1000 ft) Vertical
\nSeparation Minimum Between FL 290 and FL 410 Inclusive<\/em> (Doc
\n9574). This circular introduces a unified framework which enables
\nan analytical derivation of all these collision risk models. The
\nreason why it is possible to derive them under the same framework
\nis that these CRMs share similar modelling assumptions.<\/p>\n

Chapter 2 introduces the appropriate nomenclature. Chapter 3
\nreviews the modelling of the uncertainty associated with aircraft
\nlocation and examines some extensions to current CRMs. It appears
\nthat, from a controller's viewpoint, the modelling of uncertainties
\ndescribed in Chapter 3 is inadequate in environments with a high
\nupdate rate of aircraft positions. Actually, all CRMs presented in
\nDocs 9689 and 9574 apply to environments with a low update rate.
\nPossible methods for modelling uncertainties in environments with a
\nhigh update rate are suggested in Chapter3, 3.6.<\/p>\n

Chapter 4 introduces a key formula, called the Rice Formula,
\nwhich plays a major part in the derivation of CRMs. Derivation of
\nCRMs using the Rice Formula is presented in Chapters 5 to 7.<\/p>\n

Chapter 8 and 9 present a generic CRM which applies to any
\noperational scenario involving a pair of aircraft, either for
\nsame\/opposite directions (Chapter 8) or for crossing routes
\n(Chapter 9). Since this CRM is particularly interesting for the
\nrisk assessment of predetermined operational hazards, it is
\npresented in a more general form first, followed by an important
\napplication of this CRM in an ADS-C environment.<\/p>\n

Finally, Chapter 10 provides a list of recommended reading and
\nreference material.<\/p>\n","protected":false},"excerpt":{"rendered":"
