Paper 27 -- DEVELOPMENT OF AN ALGORITHM TO MODEL THE LANDING OPERATIONS, BASED ON STATISTICAL ANALYSIS OF ACTUAL DATA SURVEY (PROESTOP)

This paper presents the overall method followed to develop the stochastic algorithm based on Montecarlo simulations used by PROESTOP, a tool that estimates the runway occupancy time for arrivals (ROTA) and provides new exit taxiways optimum allocation on a given scenario. The tool, developed by INECO, is currently in use in different projects, namely the development and revision of Spanish airports master plans, the SPADE project within the VI EU Framework Programme and more recently, after the acquisition of a license, in support to studies carried out by Eurocontrol. This paper describes the whole process from the review of existing methods to the final validation of the model: Reasons for actual data need, and existing models deficiencies are mentioned and illustrated. Data survey design, execution and post-process is presented, including estimation of errors, outliers identification and fitting regression models. Discussion of most influence variables on ROTA, based on statistical analysis, is summarised. An alternative clustering of aircraft models attending their performances is introduced. An Estimated Logistic regression model is described to estimate the exit taxiway probability. Different alternative speed functions along the runway are presented and compared with actual landing data. The steps required to deal with a stochastic model based on Montecarlo simulations are described. The use of standard (Normal, Erlang, etc.) and non-standard (Johnson curves) probability distribution for fitting the input variables was introduced. Description and outcomes of the validation process are presented. And, finally, the current applications of the tool are mentioned.
