Propeller efficiency is the

ratio of thrust horsepower to brake horsepower.

Frequent inspections should be made of aircraft exhaust manifold-type heating systems to minimize the possibility of

exhaust gases leaking into the flight deck.

What effect, if any, would a change in ambient temperature or air density have on gas turbine engine performance?

As temperature increases, thrust decreases.

A way to detect a broken magneto primary grounding lead is to

idle the engine and momentarily turn the ignition off.

Detonation may occur at high-power settings when

the fuel mixture ignites instantaneously instead of burning progressively and evenly.

Carburetor ice

is more likely to form when outside air temperatures are below 70 degrees F and relative humidity is above 80%.

Leaving the carburetor heat on during takeoff

will increase the ground roll.

Which weather chart depicts conditions forecast to exist at a specific time in the future?

12-Hour Significant Weather Prognostic Chart.

Hatching on a Constant Pressure Analysis Chart indicates

windspeed 70 knots to 110 knots.

With regard to windflow patterns shown on surface analysis charts; when the isobars are

close together, the pressure gradient force is greater and wind velocities are stronger.

The uncontrolled firing of the fuel/air charge in advance of normal spark ignition is known as

pre-ignition.

The Surface Analysis Chart depicts

actual frontal positions, pressure patterns, temperature, dewpoint, wind, weather, and obstructions to vision at the valid time of the chart.

An abnormally high engine oil temperature indication may be caused by

the oil level being too low.

Fuel and exhaust enter and exit a 4-cycle engine

through intake and exhaust valves.

Why does the wind have a tendency to flow parallel to the isobars above the friction level?

Coriolis force tends to counterbalance the horizontal pressure gradient.

The U.S. High-Level Significant Weather Prognostic Chart forecasts significant weather for what airspace?

FL250 to FL630

Which provides a graphic display of both VFR and IFR weather?

Weather Depiction Chart.

A detuning of engine crankshaft counterweights is a source of overstress that may be caused by

rapid opening and closing of the throttle.

If the ground wire between the magneto and the ignition switch becomes disconnected, the engine

could accidently start if the propeller is moved with fuel in the cylinder.

Fouling of spark plugs is more apt to occur if the aircraft

gains altitude with no mixture adjustment.

Applying carburetor heat will

enrich the fuel/air mixture.

On a Surface Analysis Chart, the solid lines that depict sea level pressure patterns are called

isobars.

The best power mixture is that fuel/air ratio at which

the most power can be obtained for any given throttle setting.

Fuel/air ratio is the ratio between the

weight of fuel and weight of air entering the cylinder.

Under what condition could an aircraft's engine logbook show no previous operating history?

After the aircraft's engine has been rebuilt by the manufacturer.

What action can a pilot take to aid in cooling an engine that is overheating during a climb?

Reduce rate of climb and increase airspeed.

In an aircraft equipped with a fixed-pitch propeller and a float-type carburetor, the first indication of carburetor ice would most likely be

loss of RPM.

For internal cooling, reciprocating aircraft engines are especially dependent on

the circulation of lubricating oil.

In aircraft equipped with constant-speed propellers and normally-aspirated engines, which procedure should be used to avoid placing undue stress on the engine components? When power is being

increased, increase the RPM before increasing the manifold pressure.

Dashed lines on a Surface Analysis Chart, if depicted, indicate that the pressure gradient is

weak.

The reason for variations in geometric pitch (twisting) along a propeller blade is that it

permits a relatively constant angle of attack along its length when in cruising flight.

Before shutdown, while at idle, the ignition key is momentarily turned OFF. The engine continues to run with no interruption; this

should not normally happen. Indicates a magneto not grounding in OFF position.

Unless adjusted, the fuel/air mixture becomes richer with an increase in altitude because the amount of fuel

remains constant while the density of air decreases.

An abnormally high engine oil temperature indication may be caused by

the oil level being too low.

During preflight in cold weather, crankcase breather lines should receive special attention because they are susceptible to being clogged by

ice from crankcase vapors that have condensed and subsequently frozen.

The basic purpose of adjusting the fuel/air mixture control at altitude is to

decrease the fuel flow to compensate for decreased air density.

To best determine general forecast weather conditions covering a wide geographic area, the pilot should refer to

Graphical Forecasts for Aviation (GFA).

Four-cycle engines are lubricated by

forcing oil directly to the components requiring lubrication.

At high altitudes, an excessively rich mixture will cause the

fouling of spark plugs.

Which statement best describes the operating principle of a constant-speed propeller?

The propeller control regulates the engine RPM and in turn the propeller RPM.

If the ground wire between the magneto and the ignition switch becomes disconnected, the engine

could accidently start if the propeller is moved with fuel in the cylinder.

If a pilot suspects that the engine (with a fixed-pitch propeller) is detonating during climb-out after takeoff, the initial corrective action to take would be to

lower the nose slightly to increase airspeed.

For internal cooling, air cooled engines are especially dependent on

the circulation of lubricating oil.

Consider a reciprocating aircraft engine. Detonation can be caused by

using a lower grade of fuel than recommended.

The difference found by subtracting the temperature of a parcel of air theoretically lifted from the surface to 500 milibars and the existing temperature at 500 milibars is called the

lifted index.

Which is true regarding preheating an aircraft during cold weather operations?

The cabin area as well as the engine should be preheated.

Fouling of spark plugs is more apt to occur if the aircraft

gains altitude with no mixture adjustment.

Which of the following is a characteristic of FADEC systems?

Greater Reliability than traditional Magnetos

What should be the first action after starting an aircraft engine?

Adjust for proper RPM and check for desired indications on the engine gauges.

Detonation occurs in a reciprocating aircraft engine when

the unburned charge in the cylinders explodes instead of burning normally.

To establish a climb after takeoff in an aircraft equipped with a constant-speed propeller, the output of the engine is reduced to climb power by decreasing manifold pressure and

decreasing RPM by increasing propeller blade angle.

On a Surface Analysis Chart, close spacing of the isobars indicates

strong pressure gradient.

Which statement is true concerning the effect of the application of carburetor heat?

It enriches the fuel/air mixture.

For takeoff, the blade angle of a controllable-pitch propeller should be set at a

small angle of attack and high RPM.

Your aircraft has an exhaust manifold type heating system. The exhaust manifold should be periodically inspected to avoid

carbon monoxide poisoning.

When total sky cover is few or scattered, the height shown on the Weather Depiction Chart is the

base of the lowest layer.

During preflight in cold weather, crankcase breather lines should receive special attention because they are susceptible to being clogged by

ice from crankcase vapors that have condensed and subsequently frozen.

The mixture control can be adjusted, which

prevents the fuel/air combination from becoming too rich at higher altitudes.

Leaving the carburetor heat on during takeoff

will increase the ground roll.

The most probable reason an engine continues to run after the ignition switch has been turned off is

a broken magneto ground wire.

Which chart provides a ready means of locating observed frontal positions and pressure centers?

Surface Analysis Chart.

What will occur if no leaning is made with the mixture control as the flight altitude increases?

The density of air entering the carburetor decreases and the amount of fuel remains constant.

The pilot controls the air/fuel ratio with the

mixture control.
