In a turbocharged engine, the _____________________ controls the volume of the exhaust gas that is directed onto the turbine. a. Wastegate. b. Intercooler. c. Pressure cycle. d. Compressor. 

2. What is NOT true about a wastegate? a. It may be manually controlled by the pilot. b. When it is closed it allows all the exhaust to bypass the turbine. c. It may have a fixed position. d. It may be controlled by an automatic controller.

3. When airflow increases through a float carburetor venturi, how does that affect the venturi pressure and the fuel flow to the engine? a. The venturi pressure increases and fuel flow to the engine increases. b. The venturi pressure decreases and fuel flow to the engine increases. c. The venturi pressure decreases and fuel flow to the engine decreases. d. The venturi pressure increases and fuel flow to the engine decreases.

5. Modern aircraft magnetos: a. Have rotating coils. b. Have rotating magnets. c. do not have coils. d. Require battery voltage to function. 

6. (True / False) Induced voltage in the secondary coil of the magneto provides the voltage necessary for the ignition spark. a. True. b. False. 

7. Magneto spark timing for operational engine RPM: a. Will facilitate a normal engine start. b. Is too late and will not allow a normal engine start. c. could produce a kickback during start. d. Needs to be advanced for a normal start.

8. An impulse coupling is usually installed: a. On both magnetos for easy starting. b. On only one magneto for starting. c. Not usually installed on reciprocating engines.
