Which alternative answer is equal to 16,300?

• 1.63 x 10 to the fourth power

• 1.63 x 10 to the negative third power

• 163 x 10 to the negative second power

Answer explanation

When working with powers of 10, a positive exponent indicates you must move the decimal to the right. The number of places the decimal should be move is equivalent to the exponent's value. Therefore, 16,300 is equal to 1.63 x 10⁴.

Which of the following is Newton's First Law of Motion, generally termed the Law of Inertia?

• To every action there is an equal and opposite reaction

• Force is proportional to the product of mass and acceleration

• Every body persists in its state of rest, or of motion in a straight line, unless acted upon by some outside force

Answer explanation

Newton's First Law of Motion explains the effect of inertia on a body. It states that a body at rest tends to remain at rest, and a body in motion tends to remain in motion (straight line and constant velocity), unless acted on by some outside force.

The purpose of providing a space underneath the plates in a lead acid battery's cell container is to

• Ensure that the electrolyte quantity ratio to the number of plates and plate area is adequate

• Prevent sediment buildup from contacting the plates and causing a short circuit

• Allow for convection flow of the electrolyte in order to provide for cooling of the plates.

Answer explanation

The positive and negative plates are kept apart by porous separators and held off the bottom of the container to prevent sediment from building up and shorting out the plates

In an AC circuit, the effective voltage is

• Equal to the maximum instantaneous voltage

• Greater than the maximum instantaneous voltage

• Less than the maximum instantaneous voltage

Answer explanation

Effective voltage in an AC circuit is also known as root mean squared, or RMS voltage and is calculated by multiplying .707 times the maximum instantaneous voltage.

What is the class of working drawing that is the description/depiction of a single part?

• Installation Drawing

• Assembly Drawing

• Detail Drawing

Answer explanation

A detail drawing is classified as a working drawing and supplies all the information required to construct a part, including all dimensions, materials, and type of finish. Answer A is incorrect because an installation drawing shows where multiple parts and components are installed in or on an aircraft. Answer B is incorrect because an assembly drawing shows how 2 or more parts are brought together to create a subassembly.

Primary responsibility for compliance with Airworthiness Directives lies with the

• Aircraft owner or operator

• Certificated mechanic holding an inspection authorization who conducts appropriate inspections

• Certificated mechanic who maintains the aircraft

Answer explanation

Although a mechanic is responsible for determining compliance with ADs during certain airwothiness inspections, the owner or operator of the aircraft is required by part 91.403 to maintain their aircraft in an airworthy condition, including compliance with applicable ADs.

What determines whether the value of a moments is preceded by a plus (+) or a minus (-) sign in aircraft weight and balance?

• The location of the weight in reference to the datum.

• The result of a weight being added or removed and its location relative to the datum.

• The location of the datum in reference to the aircraft CG

Answer explanation

The location of items in an aircraft are given as positive or negative values according to their location relative to the reference datum. Items forward of the datum have a negative arm and items aft of the datum have a positive arm.
