As already said in the Aircraft Introduction section the Macchi 202 is equipped with two different engines.
Below we have the flashcard provided by TFS and a table of the engine limitation in the 109 (considering that the engine is the same we can also take that as a reference).
The throttle controls the manifold pressure, remember is visually reversed (in-game the control is the same as in other planes).
The two levers on the left side of the cockpit are used to control the radiators (Olio = Oil; Acqua = Water).
The pitch lever (Giri) the RPMs if the pitch control is on M or Manuale (Manual).
The mixture is completely automatic.
Note: Unlike the earlier Merlin engine the Daimler-Benz that equip the 202 has a direct fuel injection system that doesn't give any problem during negative Gs manoeuvres.PITCH
The Macchi feature a variable pitch propeller with blades that can be rotated around their long axis to change the blade pitch.
Unlike a constant speed propeller which is designed to adjust itself at the desired RPM setting, in a variable pitch propeller the pilot constantly needs to set the pitch in order to keep the RPM wanted.
The airplane is equipped with an automatic pitch system with three different modes. The selector is under the throttle (low arrow in the photo).
In M or "Manuale" (Manual) the pilot is able to use the "giri" lever (the gray one on the right of the throttle see highest arrow) to set the desired pitch. As per with the throttle, also the rpm lever is reversed! So 100% or full forward is minimum rpm while 0% or full backwards is max rpm.
Since last patch the lever know works like the rpm lever of 109 E1 & E3 it's more a switch and not an axis.
In A or "Automatico" (Automatic) the system will adjust the pitch in order to try and keep 2200 rpm.
In S or "Supergiri" (super rpm) the system will adjust the pitch in order to try and keep 2400 rpm.
Note: When diving remember to watch the rpms since it's very common to over-rev the engine and break in it.THROTTLE
The gauge shown in the picture indicates your manifold pressure.
The Macchi has a W.E.P. system. It's the red button over the throttle that gives increased power when pressed.
When using it the pilot should always monitor the engine temperatures in order not to exceed them.FUEL
The fuel gauge in the Macchi is quite a curious one, it's a sort of an old weighting scale. The fuel onboard is read by the indicator on the bar.RADIATORS
The Macchi has two radiators (oil and water) located below the nose and the belly.
The pilot can monitor with the two indicators. The one on the left is for the water (A="Acqua") while the one on the right is for the Oil (O="Olio").
The gauges have two needles. E "Entrata" (Entry) stay for the temperature of the air that enter on the radiator while U "Uscita" (Exit) stay for the temperature of the air exiting the radiator, this is the needle to look.
A cruise settings is 75% for both. While in combat adjust as necessary. Keep in mind that the water rad seems more "sensible" than the oil one.
Note: To cool down the radiator air is needed. This means that if you are in a dive at high speed where the air flow through the rad is quite fast you will be able almost to close it completely, on the contrary if you put your aircraft in an aggressive climb the air flow will be weaker especially as the speed decrease so you'll need to open the rad or you will overheat your engine.
