Implementation of Apron Management at Lisboa Airport Conceptual procedure using a variable geometry principle for runway 17/35

摘要

Abstract: This work covers a study about the APRON Management implementation in acrossed runway Airport;;where the Lisboa Airport was used as a case-study;;due topersonal and professional experience. Being a service normally assured by the air trafficservices;;it’s this study intention to evaluate the viability to transfer functions normallyassociated to the previous mentioned service to the airport provider;;which maintainsnowadays a shared management model with the air traffic control services of the APRONperformed activities.Given the airport traffic growth at the airport in question and its respective configuration;;a need emerges to restructure its functioning;;implementing a new APRON managementmodel with the purpose of a rapid response for the traffic flow and its fluidity.An analysis is made in terms of regulation;;legislation;;advantages and also of the requiredconditions demanded by the activities management service;;aircraft and vehiclesmovement on the platform to be executed by the airport provider;;that in this case studywill be the SOA (Airport Operations Service).The recommended solution;;by us;;is credible in terms of a solution to some functionalproblems. This solution shows that the implementation of a model;;which we understandas of “variable geometry”;;as it conceptually;;formulates the existence of one or twoplatforms (APRON’s);;depending if it’s used the secondary runway alternatively as arunway (RWY) or a circulation route (TWY).The reason for this rotation as to do with the local specific operational conditions. In ourcase study it relates to the meteorological conditions;;but other conditions can be takeninto account to justify this rotation.The conceptual structure of this model relates to operational and financial reasons of allthe partners of airport business. On one hand it could be beneficial the closure/annulment;;in a definitive way;;of the runway in financial terms;;by an increase of space availabilityand resulting gain for some partners;;on the other hand the operational decrease;;relatedto its use;;could bring considerable loses for other partners. For that reason only by asomewhat extensive study of the consequences;;done by every partner;;could we getconclusions?Based in the available data we have;;an attempt was made to approach what we believeare the liable questions for being studied;;based on our natural knowledge of this subject.But we must consider that the mentioned knowledge can be somewhat limited;;as willalways will be necessary to gather information within the partners and also;;we believethat some of that information;;for business reasons;;could be very hard to becomeavailable.Nonetheless;;we believe that a financial study made by all the partners can bring to anenforcement of values that will be susceptible for discussion and eventually approved forthe decision making in three fronts:1. Maintaining the actual situation2. APRON Management Implementation:2.1 With or without the annulment of the runway2.2 Introduction of the geometric variable concept
