About this Exam
Prepare with the Assembly and Rigging Sectional and Final Practice Test practice quiz. This question bank includes 10 questions covering rotor, blades, part, flight, and found. Use it to review important concepts, identify knowledge gaps, and build confidence for the related exam, course, or assessment.
Sample Questions
Question
1
In an articulated rotor system, what independent motions can rotor blades perform?
Explanation:
In an articulated rotor blade, there are three independent motions about the blade’s hinge axes: flap, lead/lag, and feather. Flap is the up-and-down motion about the flap hinge, letting the blade respond to cyclic lift. Lead/lag is movement along the plane of rotation about the lead/lag hinge, driven by centrifugal forces and drag to accommodate inertia and drag effects. Feather is rotation about the feather axis, changing the blade pitch to control lift. These three actions are the separate degrees of freedom the hub articulation provides for each blade, enabling the blade to adapt to changing air loads while staying attached to the rotor hub. Other terms describe airplane body attitudes or nonstandard blade motions, so they don’t capture the three independent hinge-driven motions that define articulated rotor blades.
Question
2
Part 23 requires this to overcome jamming of flight controls
Explanation:
When flight-control reliability is at risk from a jam, having multiple independent paths or physically separated control routes for the primary surfaces is essential. Redundancy means there’s a second, independent way to move each primary surface, so if one path sticks or fails, the other can still steer the aircraft. Separation ensures that a single event can’t simultaneously affect all control paths, reducing the chance that a jam knocks out all pitch, roll, and yaw control. This design approach is what Part 23 requires to maintain controllability after a jam. A backup hydraulic system, an autopilot redundancy, or manual interlocks don’t directly guarantee continued pilot control in the same way efficient, independent control paths do.
Question
3
A Gurney flap is usually found on a control surface and is used to help center it.
Explanation:
A Gurney flap is a small tab attached to the trailing edge of a wing section or control surface. Its purpose is to increase the camber of that surface, which raises lift and changes the aerodynamic balance or moment produced by the surface. When placed on a control surface such as an elevator or aileron, this added lift on that surface helps adjust the trim moment and can make it easier to keep the surface in its neutral, centered position during flight. It’s not located on the leading edge or at the wingtip—the trailing edge is where a Gurney flap does its work. So the statement is true: it’s usually found on a control surface and helps center it.
Question
4
Where is the procedure for performing control surface rigging typically found?
Explanation:
Rigging control surfaces is a maintenance task, so the procedure is documented where maintenance procedures live. The maintenance manual provides the exact steps, required tools, permissible tolerances, and safety precautions for adjusting linkages, hinges, and actuators to achieve correct control travel and alignment. The flight manual and pilot’s operating handbook are aimed at pilots for operating the aircraft, not performing hardware adjustments. The structural manual covers the airframe’s structural data and limits, not the step-by-step rigging process. So the maintenance manual is the proper source for how to perform control surface rigging.
Question
5
In an American-made helicopter, applying left cyclic tilts the rotor disc to the left; at which part of the rotor disc will the highest blade pitch angle occur?
Explanation:
When you push left on the cyclic, the rotor disk tilts so the lift vector points to the left. The cyclic controls are phased around the blade’s azimuth so the angle of attack changes as each blade passes different positions. To produce a leftward lift while the disk is tilted, the blade in the rear portion of the disk is commanded to carry the greatest pitch, increasing lift there to support the left tilt. So, the blade at the rear of the rotor disk ends up with the highest pitch angle.
