• 1.

### Cylinders in small aircraft engines are most often arranged...

• A.

Like an "L"

• B.

In an "X" configuration

• C.

In a horizontally-opposed configuration

• D.

In a "T" configuration

C. In a horizontally-opposed configuration
Explanation
In small aircraft engines, cylinders are most often arranged in a horizontally-opposed configuration. This means that the cylinders are positioned opposite each other, with the pistons moving horizontally. This arrangement allows for a more compact design, better weight distribution, and improved cooling. Additionally, the horizontally-opposed configuration provides better balance and reduces vibrations, resulting in smoother operation of the engine.

### When fossil fuels are used to create thrust, it is...

• A.

Converting mechanical energy into chemical energy

• B.

Bernoulli's Principle

• C.

Converting chemical energy into mechanical energy

• D.

Newtons first law

C. Converting chemical energy into mechanical energy
Explanation
When fossil fuels are used to create thrust, they undergo a process called combustion, where they react with oxygen to release energy. This energy is then converted into mechanical energy, which is used to create thrust in engines such as jet engines or rockets. Therefore, the correct answer is "converting chemical energy into mechanical energy."

### What engine component uses Bernoulli's Principle?

• A.

An alternator

• B.

A carburetor

• C.

A magneto

• D.

A piston

B. A carburetor
Explanation
A carburetor is the engine component that uses Bernoulli's Principle. Bernoulli's principle states that as the speed of a fluid increases, its pressure decreases. In a carburetor, air flows through a narrow passage called a venturi, which causes the air to speed up. This decrease in pressure creates a vacuum, which draws fuel from the carburetor's fuel bowl. The fuel mixes with the air and is then delivered to the engine for combustion. Therefore, a carburetor utilizes Bernoulli's Principle to regulate the air-fuel mixture in an internal combustion engine.

### What instrument uses the principle of a gyroscope for operation?

• A.

Altimeter

• B.

Attitude indicator

• C.

• D.

Both B and C

D. Both B and C
Explanation
Both the attitude indicator and heading indicator use the principle of a gyroscope for operation. A gyroscope is a device that maintains its orientation regardless of any external forces acting upon it. In the case of the attitude indicator, the gyroscope is used to indicate the aircraft's pitch and roll attitude. In the case of the heading indicator, the gyroscope is used to indicate the aircraft's heading or direction. Therefore, the correct answer is Both B and C.

### Under standard conditions, a parcel of air, one square inch and 50 miles tall weighs...

• A.

29.92 pounds

• B.

1013.2 grams

• C.

14.7 pounds

• D.

None of the above

D. None of the above
Explanation
Air pressure varies with altitude, so the weight of a parcel of air cannot be determined solely based on its dimensions. Standard atmospheric pressure at sea level is approximately 29.92 inches of mercury (inHg) or 1013.2 millibars (mb), but this pressure decreases with increasing altitude. Therefore, the weight of a parcel of air would depend on the atmospheric pressure at its specific altitude.

### In a flight profile, what phase is reached when the pilot levels off at the desired altitude.

• A.

Decent

• B.

Approach

• C.

Departure

• D.

Cruise

D. Cruise
Explanation
When the pilot levels off at the desired altitude, it indicates that the flight has entered the cruise phase. During this phase, the aircraft maintains a steady altitude and speed, usually at a high altitude, for the majority of the journey. This phase is characterized by a relaxed and stable flight condition, allowing passengers to move freely within the cabin and enjoy a smoother ride.

### The VFR weather minimums for class C airspace are...

• A.

500' below the clouds

• B.

1000' above the clouds

• C.

2000' horizontally from any cloud

• D.

All of the above

D. All of the above
Explanation
The VFR weather minimums for class C airspace are all of the above options. This means that pilots must maintain a minimum of 500' below the clouds, 1000' above the clouds, and 2000' horizontally from any cloud while flying in class C airspace. These minimums are in place to ensure safe visibility and separation from other aircraft in the airspace.

### Runway numbers of "11" and "29" are...* Degrees

• A.

110* and 290* true

• B.

110* and 290* magnetic

• C.

11* and 29* true

• D.

11* and 29* magnetic

B. 110* and 290* magnetic
Explanation
The runway numbers "11" and "29" are magnetic. Runway numbers are based on the magnetic heading of the runway, which is the direction in which an aircraft would be heading when taking off or landing. In this case, the runway heading is 110 degrees and 290 degrees magnetic.

### When approaching a precision runway, the pilot sees 8 stripes at the beginning of the runway. What do these stripes tell the pilot?

• A.

The runway is 8000' long

• B.

The runway is closed

• C.

These are the threshold marking of a precision runway

• D.

A portion of the runway is unusable

C. These are the threshold marking of a precision runway
Explanation
The presence of 8 stripes at the beginning of the runway indicates that these are the threshold markings of a precision runway. Threshold markings are used to define the beginning of the runway for landing purposes and provide visual cues to pilots. These markings help pilots align their aircraft properly for landing and takeoff. Therefore, the correct answer suggests that the pilot is approaching a precision runway and should be aware of the threshold markings for landing procedures.

### If the airport beacon is flashing one white, one green, one yellow, it is a...

• A.

Water airport

• B.

Civilian airport

• C.

Military airport

• D.

Helicopter airport

D. Helicopter airport
Explanation
The flashing of one white, one green, and one yellow beacon indicates that it is a helicopter airport. This is because the color combination is specific to helicopter landing areas. The white light signifies a helipad or landing area, the green light indicates the approach or takeoff path, and the yellow light is used to mark the touchdown and lift-off area. Therefore, the given color sequence suggests that the airport is specifically designed for helicopter operations.

### Which wind direction indicator shows where the wind is from?

• A.

Wind sock

• B.

Tetrahedron

• C.

Wind tee

• D.

Segmented circle

A. Wind sock
Explanation
A wind sock is a wind direction indicator that shows where the wind is coming from. It is a large fabric tube open at both ends, with one end attached to a pole or mast. The wind fills the sock and causes it to point in the direction from which the wind is blowing. This makes it a useful tool for pilots, meteorologists, and anyone else who needs to know the wind direction. The other options, tetrahedron, wind tee, and segmented circle, do not specifically indicate wind direction.

### A sectional aeronautical chart has a scale of...

• A.

1inch equals one nautical mile

• B.

1inch equals 500,000 miles

• C.

1inch equals 5,280 feet

• D.

1inch equals 8 statute miles

D. 1inch equals 8 statute miles
Explanation
A sectional aeronautical chart is a specialized map used by pilots for navigation. It provides information about the airspace, landmarks, and other relevant details for flying. The scale of 1 inch equals 8 statute miles means that every inch on the chart represents a distance of 8 statute miles in the actual world. This scale allows pilots to accurately measure distances and plan their routes accordingly.

### A latitude line is...

• A.

A meridian

• B.

The Prime meridian

• C.

A line from the North Pole to the South Pole

• D.

A parallel

D. A parallel
Explanation
The correct answer is "A parallel." A latitude line is referred to as a parallel because it runs parallel to the equator and is used to measure the distance north or south of the equator. It is not a meridian, which refers to lines of longitude, nor is it the Prime meridian, which is the specific line of longitude that passes through Greenwich, England. A latitude line does not run from the North Pole to the South Pole; rather, it circles the Earth horizontally.

### A statute mile is...

• A.

6,076 feet

• B.

5,280 feet

• C.

6,076 meters

• D.

5,280 meters

B. 5,280 feet
Explanation
A statute mile is equal to 5,280 feet. This is a standard unit of measurement used in the United States and other countries that were once part of the British Empire. It is commonly used in road signs, aviation, and other applications where distance needs to be measured.
