Pilot's Handling Notes for a Fiat G.12CA with Alfa Romeo 128/RC18 engines
*************************************************************************

The three 860hp Alfa Romeo 128/RC18 (Bristol Pegasus) engines have automated mixture controls, and manually applied carb heat controls. Superchargers give rated power up to 1800 metres. Each engine can briefly deliver 930hp for take off below 1800 metres. This engine has constant speed airscrews which can be feathered. The British engines and screws cause swing to the right. The virtual flight engineer will operate the oil cooler shutters and select the appropriate supercharger gear ratio throughout the flight according to the engine RPM demanded, current altitude and the weather. The engine cowl flaps are under pilot control in this simulation.

AUTOMIXTURE - This engine has automixture in real life and in MSFS. 

The manifold pressure gauges of this aircraft are calibrated in Kg/Cm^2 abbreviated C.

CARB HEAT - When C < 0.8 and OAT < +5C apply CARB HEAT for 30 seconds every few minutes to clear carb ice. Use of CARB HEAT CAUSES significant LOSS OF POWER.

Maximum fuel load is 7,116lbs of 87 Octane AVGAS. This is loaded by default in FS9 to allow the longest routes flown in real life, but restricts payload to twelve passengers plus bags. 

Post war initial design cruise altitude is 3000 metres. Operational ceiling is always higher. 

CAUTION - this aircraft has airscrew de-icing but NO AIRFRAME DE-ICING.

The landing gear is approved for use from unpaved (but not unprepared) surfaces. This aircraft has limited STOL capability.

Read 'How to fly the Fiat G.12' before flight.
