Hi kev4242, if you mean that you just want to add new liveries to exisiting ai aircraft then all you do is place the liveries in the exisisting aircraft file and enter them in the aircraft.cfg i.e[fltsim.0] last number + 1title=Your new liverysim=A319_CFM_IFDG_011model=panel=sound=texture= (texture file name)kb_checklists=kb_reference=atc_id=atc_airline=Czech Airlinesatc_flight_number=264atc_heavy=0ui_manufacturer=Czech Airlinesui_type="A319-111"ui_variation=Czech Airlinesif the liveries are compatible with the ai aircraft then they will show up, if not then you will just have white aircraft flying around. Ttools has nothing to do with this process and only compiles and decompiles the flight plans.If that was what you were asking then have fun, if not then i had a chance to practice my typimg skills
