ASTB Decimal Conversion Practice Quiz

A pedigree is a record of descent showing the lineage or ancestry of a person or animal, typically used in reference to breeding and genetic inheritance.

A warm front typically brings long periods of rain and fog as it advances, leading to cloudy and wet conditions.

Actual air speed is faster than indicated air speed at higher altitudes due to the decrease in air density, which affects the accuracy of the airspeed indicators.

When the airflow separates from the wings upper surface, it results in a stall which can lead to a loss of lift and potential loss of control of the aircraft.

A nautical mile is a unit of measurement used in air and marine navigation. It is based on the circumference of the Earth and is equal to one minute of latitude. 1 nautical mile is equivalent to 6076 feet and approximately 1.15 statute miles.

Yaw is the term used to describe the left or right movement of an aircraft's nose along its vertical axis. Pitch refers to the up or down movement of an aircraft's nose along its lateral axis. Roll is the rotation of an aircraft around its longitudinal axis. The rudder is a control surface used to steer the aircraft along the yaw axis.

To convert a fraction to decimal, simply divide the numerator by the denominator. In this case, 1 divided by 3 equals 0.33 or .33.

To find the decimal equivalent of a fraction, divide the numerator by the denominator. In this case, 1 ÷ 4 = 0.25 or .25.

To convert a fraction to a decimal, divide the numerator by the denominator. In this case, 1 divided by 5 is 0.20 or .20 when written in decimal form.

To find the decimal equivalent of a fraction, simply divide the numerator by the denominator. In this case, 1 divided by 6 is equal to 0.166666... which is rounded to .17.

To find the decimal equivalent of a fraction, divide the numerator by the denominator. In this case, 1 ÷ 7 = 0.142857 (rounded to six decimal places).

To convert a fraction to a decimal, divide the numerator by the denominator. In this case, 1 divided by 8 equals 0.125.

To calculate 1/9, divide 1 by 9 to get the recurring decimal .111. The correct answer is .111, not .10, .99, or .25.

Flaps are movable control surfaces on the wings of an aircraft that can increase lift and reduce drag when deployed. Ailerons control the roll of the aircraft, elevators control pitch, and the rudder controls yaw.

Ailerons are primary flight control surfaces on an aircraft's wings that control roll by moving in opposite directions to one another.

Ailerons are primary control surfaces that control the roll of an aircraft, allowing it to bank left or right. Elevators control pitch, rudders control yaw, and flaps are used to increase lift or drag.

The Elevators control the pitch of an aircraft, which is movement along the Longitudinal Axis, by changing the aircraft's angle of attack.

Elevators control the pitch of an aircraft by changing the aircraft's pitch attitude.

Altitude is controlled by adjusting the elevator, which controls the pitch of an aircraft. Ailerons control the roll, throttle controls the speed, and rudder controls the yaw of the aircraft.

The ailerons are the control surfaces on the wings of an aircraft that control the roll motion around the lateral axis.

Yaw refers to the rotation of an aircraft around its vertical axis. The rudder is the primary control surface responsible for controlling yaw.

The rudder is responsible for controlling the yaw of an aircraft, which is movement around the vertical axis. Elevators control pitch, flaps control lift, and ailerons control roll.

A sonic boom is the audible sound associated with the shock waves created by an object traveling through the air at or above the speed of sound. It is characterized by an abrupt pressure change.

Dihedral wings are designed to improve stability by providing inherent stability against rolling motions.

Aspect Ratio is the correct term used to describe the ratio of the wingspan to the average wing width of an aircraft. It is an important characteristic that affects the aerodynamic performance of the aircraft.

When helicopter pilots experience engine failure, they use a technique called autorotation to safely land the helicopter without engine power.

RIO typically refers to Radar Intercept Officer in the context of military aviation, specifically in aircraft such as the F-14 Tomcat.

A Spring Tide occurs when the sun, moon, and earth are aligned, creating a stronger gravitational pull leading to larger tidal changes.

A neap tide is a period of moderate tides that occurs when the sun and moon are at right angles to each other. This results in the smallest difference between high and low tide levels.
