The importing tool is an Access implemented database. Its name is ImportETMS.mdb. This tool’s primary goal is to import the two text files described before and save all the flights into a new format, AERO2K predefined format.

3.1. AERO2K tables format
The structure of AERO2K application tables and indexes are shown in Table 57, Table 58, Table 59 and Table 60.
