Cessna Caravan C208 Exam

Which type of construction is the C208? Semi Monocoque The PT6 Engine used (x) Axial and (y) centrifugal compressors. X=3 Y=1 How are the axial compressors connected to the centrifugal compressor? Mechanically, both are mounted on the same shaft How is the compressor turbine connected to the power turbine? By air flow only How many fuel nozzles does the PT6 use? 14 How many complete turns does the airflow go through on the PT6? 4 What is the proper operational sequence for this engine? Intake - Compressor - Combustion - 2 Turbines - Exhaust How many US Quarts of oil does the Caravan take? 14 Oil pressure is provided by an engine driven pump and delivered under pressure to: All of them What is the P2.5 air? Bleed air taken of the axial compressor What is P3 air? Bleed air taken of the centrifugal compressor What is the percentage of NG for automatic starter cutoff? 46% A hot start could be caused by? All of them During GPU start, you experience a hot start. Ten seconds after energizing the starter you move the fuel condition lever to cut off. Now you should Start Switch to Motor 10 Seconds then off Is it important to have the ignition switch in the Norm position during start?

The turbine did not reach minimum idle RPM after start ITT means ---- and is measured ---- Inter Turbine Temp, between the two turbines Springs and counterweights drive the propeller blades toward: High Pitch The normal propeller governor Uses oil pressure to vary blade pitch The overspeed governor will always restrict speed to a maximum of 1976 The overspeed governor test switch Resets the overspeed governor limit to activate at 1750 +/- 60 RPM The fuel topping governor activates at --- % of the RPM selected by the pilot 106% The auxiliary fuel boost pump is used for starting and When the ejector pump fails A red button pops up on the top of the fuel filter when The filter is by-passing fuel Fuel rejected by the engine on shut down Drains into a fireproof can on the firewall The voltammeter and its associated switch are used to read All of them When the External Power switch is placed in the BUS position External power is applied to the main bus The standby electrical system Is powered by a belt driven alternator
