With 100/130 Octane fuel now readily available across Italy these were powered by Bristol Pegasus 48 engines which delivered much higher power for take off. The G.12LB shared the super stretched fuselage of the low powered G.12L, but in the G.12LB it housed a galley and steward for the first time since the G.12LBs were procured to fly the longest Alitalia domestic routes. Seating reduced to 8 x 2 and even that required reduced fuel. The cargo pannier of the CA was retained. All four were sold to the Italian Air Force (AMI) in 1950. Skin by Manuele Villa, May 2009.

With the centre tank empty payload rises from 2,200lbs to 4,300lbs for short hauls. This allows 16 pax plus bags in the fusleage and 1,100lbs (500 Kg) of cargo in the ventral pannier.

Max fuel is loaded by default in FS9 to permit longest routes flown in real life. The real aircraft had more than three tanks.

The crew could select any angle. The angles below are the real 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.
