handled as Alitalia aircraft account for 50% of the ones at Fiumicino. In May 2006, Italy's Civil Aviation Authority announced that it took off the limitation of 3 ramp handlers in Rome Leonardo da Vinci airport. ARE Group and Aviapartner announced that they would create a company called Aviapartner (51% Aviapartner; 49% ARE Group) to serve Milan Malpensa and Rome Leonardo da Vinci. Since 2005, the airport operates a category III B instrument landing system (ILS). Further improvement work was implemented in 2007 to enable the airport to handle 30 takeoffs/landings per hour, up from 10, in the event of thick fog. Three runways presently operate at Leonardo da Vinci airport: 16L/34R and 16R/34L (separated by a distance of , and 07/25, used only westwards for takeoffs owing to the prevailing winds. The airport used to have a fourth runway, 16C/34C which was located alongside 16L/34R, it was mostly used as a taxiway or as a backup for 16L/34R; the runway is now designated as Taxiway "D". In 2010, the new single baggage handling system for more efficient luggage delivery began operations. Several projects are planned. These include the construction of an environmentally-friendly cogeneration system, which would allow the airport to produce its own energy; the "Masterplan Fiumicino Nord", involving four new terminals and two new runways to be built in the future handling 100 million passengers per year. Terminals Overview As of 2021, after major expansion and refurbishment works, the airport now features two reorganised passenger terminals, one of which is currently operational. Terminal 1 (Gates A1–A83) has been closed for renovations with many gates currently unused, its main pier is currently being expanded with a second one next to it. Terminal 3 (Gates E1–E52) is the largest terminal which serves as the home base for ITA Airways amongst several other airlines. It also incorporates the former Terminal 5 as well as the satellite building for non-Schengen departures. A new central airside hall has been built as its middle part in recent years. Development The terminals were upgraded during the 1990s and 2000s. In 1991, the domestic Pier A with 12 gates opened, followed in 1995 by the international Pier B with 10 gates and in 1999 by the international Satellite C with 14 gates. In 2000, the new domestic Terminal A opened, and the terminal buildings, then consisting of Terminal A (with Pier A), Terminal AA, Terminal B
