The Auch - Lamothe aerodrome has planned the implementation of the company JCB AERO (specialized in the inner part of small size no commercial planes and others) in July 2010. The aim of the project is to design systems that allow and facilitate the access to the infrastructures employed for the new company, as well as a modernisation and renovation of the existing facilities. In the SNIA department (facilities department from the french directorate general of civil aviation) I have been the six months of my practicum. This project contains four important parts: AUDIT, AVP, PRO and DCE. · In AUDIT is described the data and the information about the original airfield runway lightning. · In AVP are presented the modifications required to do in the airfield runway lightning, and a global estimated cost of it. · In PRO there is the detailed study and precise project to realize. · DCE is a documentation for company consultation, in which is included all the data needed for the physical construction as well as an estimated study of the total price. During all the practium, including the analysis and creation of the procedures, the indications and requirements established Annex 14 and the CHEA document (french origin) have been followed. Autocad 2006 is the software used for the drawing of the plans, showing the perfect fitting for this kind of work.
