Front

During which stroke of a reciprocating engine is the fuel air mixture ignited?

Back

Power stroke

Front

In which type of reciprocating engine are the cylinders arranged on opposite sides of the crankcase in order to provide a high power-to-weight ratio?

Back

Horizontally-opposed engine

Front

Which of these events does NOT occur during a four-stroke reciprocating engine cycle? A fuel and air mixture is sucked into the cylinder through the intake valve., A fuel and air mixture is ejected through the exhaust valve., A fuel and air mixture is compressed., A fuel and air mixture is ignited.

Back

A fuel and air mixture is ejected through the exhaust valve.

Front

What is the purpose of combustion in an internal combustion engine?

Back

To apply downward force on the pistons in the engine

Front

True or False. When decreasing power to a constant-speed propeller, the pilot should first reduce RPM before reducing manifold pressure.

Back

False

Front

True or False. When decreasing power to a constant-speed propeller, the pilot should first reduce RPM before reducing manifold pressure.

Back

Engine roughness

Front

What would occur if the engine on a single-engine aircraft stops?

Back

The propeller blades would revert to a flat pitch so the propeller can still deliver power.

Front

What happens when the pilot decreases propeller RPM?

Back

Propeller pitch increases

Front

Where should you set the fuel-air mixture when taking off in an airplane on a cool day from an airport at sea level?

Back

The "full-rich" position

Front

What is the difference between carburetor and fuel injection systems?

Back

A carburetor mixes fuel and air before sending it to the intake manifold, while a fuel injection system delivers fuel and air directly to the cylinder.
