Question 1
Which equation represents the moment in weight and balance calculations?
Correct Answer:
Weight x Arm = Moment
Explanation:
Moment is the turning effect produced by a weight located at a certain distance from a reference point. In weight and balance, you determine this turning effect by multiplying the weight (in pounds) by its arm (the distance in feet from the chosen datum). The product, measured in pound-feet, represents the moment. That’s why the equation Weight x Arm = Moment is the correct representation. The other forms don’t reflect how moments are formed: dividing moment by weight would give the arm, adding weight and arm isn’t a valid way to compute a turning effect, and subtracting weight from a moment isn’t how moments are used in balance calculations. In practice, you compute each item’s moment this way and sum them to get the total moment, then divide by the total weight to find the center of gravity.
Question 2
What is the primary applicability of the 100-hour inspection?
Correct Answer:
Only used for hire
Explanation:
The main idea is that the 100-hour inspection is a maintenance interval tied to aircraft used for hire. It is required for airplanes that carry people or property for compensation, or that are used for flight instruction for hire. Because of that, private operations under Part 91 aren’t governed by a mandatory 100-hour schedule—their routine checks follow the annual inspection instead. So, describing the 100-hour inspection as primarily applicable to aircraft used for hire accurately captures its purpose. It isn’t a universal requirement for all aircraft, it isn’t limited to private operations, and it isn’t optional for airplanes used for hire.
Question 3
What type of stress acts parallel to the surface?
Correct Answer:
Shear
Explanation:
Stress that acts parallel to a surface is called shear stress. It happens when forces try to slide one portion of the material past another along the plane of the surface, causing layers to shear past each other and change the angle between them. This is different from tension or compression, which act normal to the surface and pull or push along the surface’s perpendicular direction. In bending, the primary effect is normal stress across the cross-section (tension on one side, compression on the other), though shear can also occur, the characteristic parallel-to-surface action is the hallmark of shear stress.
Question 4
Which factor is used to obtain the actual track after converting to true course?
Correct Answer:
Wind.
Explanation:
Actual track is the path you actually fly over the ground. Once you convert a course to true course, the thing that shifts that path is wind. The air moves relative to the ground, so a wind blowing across your intended route pushes your aircraft sideways, creating drift. The wind’s speed and direction determine how much drift you get, and thus what the true ground track ends up being. Temperature, altitude, and humidity affect air density and performance, but they don’t change the ground path as directly as wind does. To obtain the actual track, you account for wind by estimating the drift it causes and adjusting your heading accordingly.
Question 5
Which of the following is NOT a parasite drag type?
Correct Answer:
Induced drag
Explanation:
Drag is split into parasite drag and induced drag. Parasite drag includes form drag, which comes from the shape and pressure distribution around the aircraft; skin friction drag, due to viscous shear on the surfaces; and interference drag, from the disruption of flow where components meet. Induced drag is different because it arises from the wing producing lift. The lift creates wingtip vortices and a downwash that costs energy, showing up as drag even though it isn’t caused by surface friction or pressure on the airframe. Because it’s not tied to the airframe’s surface interactions like the other three, induced drag is not a parasite drag type.
