description=The original 12 seat G.12C was rejected by all potential buyers. The 14 seat G.12CR for ultra short routes added a bench seat facing the door and was certificated for take off at no more than 12,800Kg (28,219lbs). However with full fuel the CR could lift only four passengers plus bags. During the summer of 1941 the first CR became the VIP transport of the Chief of the General Staff based at Rome (LIRU) flying to everywhere Italian troops were serving. Four more later flew scheduled VIP / diplomatic services with Nucleo Comunicazioni A.L.I. as part of the wartime 'Special Air Service' based at Rome (LIRA). One later served with 605 Sq flying CASEVAC missions from the Ukraine. See G.12 History.rtf in common folder. Skin by Manuele Villa, May 2009.

With full fuel the Fiat G.12CR could carry only four passengers plus bags. Full fuel and restricted payload is loaded by default in FS9 to allow the longest routes flown in real life to also be flown in FS9.

[Flaps.0]
Max flap was 48 degrees. The crew could select any angle. The angles below are the recommended angles for max gross departure and typical landing weight. I suspect the crew selected 20 then 45 during approach without using 15, but we must select flap stage by stage in MSFS. See on screen handling notes and 'How to fly the Fiat G.12'.
