3.1. Unit system:
It is possible to select the unit system either metric or US system.
3.2. Aircraft modifications:
It is possible to consult the aircraft modifications validated for the aircraft chosen. The modifications enumerate the weight variant certified for the aircraft, the cargo configuration, the fuel system installed on the aircraft…

3.3. Aircraft configurations:
Through the Aircraft Configuration frame, the user can: . Set the index formula. . Define the average weights for the passengers, crew and trolley. . Consult the tanks‘ characteristics and the fuel management curve. . Consult and update the cargo holds‘ characteristics. The update function enables
to take into account the modifications that can be carried out in the cargo holds: installation of a new cargo system, installation of an ACT (Auxiliary Center Tank) or an UCRC (Under Crew Rest Container)… For instance, for the A320 family, the program can select any of the available cargo options: Bulk, CLS (Cargo Loading System), CLS and Occasional Bulk…
. Consult and update the certified design weights and the certified design CG limits. The update function allows to select a new weight variant and/or a new certified CG envelope that has been approved in the Aircraft Flight Manual.

3.4. Cabin layout:
Through the cabin layout frame, the user can visualize or create a cabin layout thanks to a graphical interface. The cabin layout describes all the main deck‘s characteristics that affect the aircraft CG position: passenger seats, cabin attendant seats, lavatories, galleys and the aircraft section. Some specific functions allow to create quickly a new cabin layout: utilization of the pitch, copy of the seats when the left and the right side of the cabin are identical.
With those users entries and with the aircraft data, the LTS carries out the following tasks: . Calculation of the influence of passengers, cargo and fuel loading on the aircraft weight and CG position. . Calculation of the operational margins (to consider the different errors and assumptions made during a CG determination). . Productions of the Load and Trim sheet and of the AHM 050 document.
