Propeller Fine Pitch
Fine pitch (high RPM) is maintained by means of oil pressure.
Propeller Coarse Pitch
Coarse pitch (low RPM) is maintained by a mechanical device comprising counterweights which are acted upon by centrifugal force.
Propeller Control
The propeller control has a detent in the high RPM portion of the operating range which allows for adjustment from 2500 RPM to 2700 RPM. To move the propeller control lever to the LOW RPM position the detent must be passed.
Propeller Governor
When the pilot has selected a desired engine RPM, the propeller governor will automatically adjust the pitch of the propeller blades to maintain selected RPM, by varying the oil pressure.
NOTE: Propeller Oil Pressure Loss
In case of total oil pressure loss the propeller blades move into coarse pitch (low RPM), thus preventing engine over speed.
NOTE: Throttle Control
Due to the constant speed propeller, opening of the throttle will increase the manifold pressure, not necessarily the RPM.
How is manifold pressure indicated?
In inches of Mercury.
Total Fuel Quantity
Each wing is equipped with an integral fuel tank holding 23,5 US gallons thus giving the aircraft a total capacity of 47 US gallons.
Unusable Fuel Quantity
The tanks can be completely emptied in level flight, but a normal amount of unusable fuel is 2,5 US gallons per tank. Thus, the total usable fuel is 42 US gallons.
NOTE: Fuel Quantity Accurate Indication
Straight and level flight is required for accurate indication of fuel quantity.
WARNING: Fuel Indication
Straight and level coordinated flight is required for the most accurate indication of the fuel quantity, but with partly filled tanks each fuel indicator may i.a.w. the technical specifications show as much as 3 1/2 US Gall more than the actual quantity, - and with completely empty tanks indicators may show as much as 2 Gall in each tank.
*NOTE: Fuel Tank Selector
From the OFF position the fuel tanks can be selected only by turning the fuel selector clockwise. Any tank can now be selected by turning the selector in either direction. The OFF position can be selected only by turning the fuel selector counterclockwise with the center lock depressed.
Fuel Pumps
The engine is equipped with an engine driven diaphragm fuel pump. An electrically driven auxiliary fuel pump is also incorporated in the fuel system.
(OBS: Only the auxiliary fuel pump can be operated by the pilot)
Generator (Volt, Output and Bus)
The electrical system is powered by an engine driven 28V generator with a maximum output of 70 amp.
The generator supplies power to both the primary and the secondary buses.
Battery (Volt and Bus)
24V.
In the ON position the aircraft battery is connected to the primary bus only.
CAUTION: Battery OFF with Generator ON
If battery switch intentionally or unintentionally is turned odd while the generator is charging primary and secondary buses, do not turn battery back on, since it may cause damage to the voltage regulator and thence cause loss of generator power.
NOTE: Battery with External Power
BAT switch shall be in OFF position when external power is used, otherwise the external power is shut off.
NOTE: EPU
To operate the Standby Attitude Indicator, the VHF 2 COM radio and the map lights the EPU switch must be switched in ON position. Leaving the EPU in ON after aircraft shutdown could result in EPU battery discharge or damage.
CAUTION: EPU with External Power
The EPU switch shall be in OFF position whenever external power is connected to the aircraft.
Canopy Warning Light
The canopy warning system includes two micro-switches installed in the canopy frame.
When the canopy is unlocked and the BAT switch is ON, the red light CANOPY will illuminate. In addition to this warning, also an audio signal sounds, when any of the IGN switches is ON and the canopy is unlocked.
Generator Caution Light
An amber GEN caution light will illuminate if the voltage of the bus drops below 25 +/- 0,5V.
