While cruising at 9,500 feet MSL, the fuel/air mixture is properly adjusted. What will occur if a descent to 4,500 feet MSL is made without readjusting the mixture?

There will be more fuel in the cylinders than is needed for normal combustion, and the excess fuel will absorb heat and cool the engine.

The excessively rich mixture will create higher cylinder head temperatures and may cause detonation.

The fuel/air mixture may become excessively lean.

In an airplane with a constant-speed propeller, which of the following procedures should be used?

When power is increased or decreased, adjust manifold pressure before rpm.

When power is decreased, reduce rpm before manifold pressure.

When power is increased, increase rpm before manifold pressure.

When operating a constant-speed propeller

avoid low rpm setting with high manifold pressures.

always use a rich mixture with high rpm settings.

pumping foreign matter into the fuel lines.

overheating the fuel pump, leading to failure.

The battery master switch should be turned to OFF after the engine is stopped to avoid the battery discharging through

the alternator or generator.

Which combination of atmospheric conditions will reduce airplane takeoff and climb performance?

Low temperature, low relative humidity, and low density altitude.

High temperature, low relative humidity, and low density altitude.

Which procedure should you follow to avoid wake turbulence if a large jet crosses your course from left to right approximately 1 mile ahead and at your altitude?

Make sure you are slightly above the path of the jet.

Slow your airspeed to VA and maintain altitude and course.

Make sure you are slightly below the path of the jet and perpendicular to the course.

What is ground effect?

The result of the disruption of the airflow patterns about the wings of an airplane to the point where the wings will no longer support the airplane in flight.

The result of an alteration in airflow patterns increasing induced drag about the wings of an airplane.

The result of the interference of the surface of the earth with the airflow patterns about an airplane.
