About this Exam
Prepare with the Aircraft Electronics Technician Practice Test practice quiz. This question bank includes 10 questions covering describes, circuit, quantity, term, and state. Use it to review important concepts, identify knowledge gaps, and build confidence for the related exam, course, or assessment.
Sample Questions
Question
1
In circuit analysis, the quantity represented by the letter L is known as which quantity?
Explanation:
L is the symbol for inductance, a property that measures how strongly a circuit element resists changes in current due to its magnetic field. In circuits, the voltage across an inductor is proportional to the rate of change of current: v = L di/dt, so larger inductance means a larger voltage response to a changing current. Inductance is also related to the energy stored in the magnetic field, W = (1/2) L I^2, and its unit is the henry. The other options refer to different concepts: capacitance (C) relates to charge and voltage, resistance (R) relates to opposition to current, and magnetism is a broader field concept rather than a specific circuit quantity. So, the quantity represented by L is inductance.
Question
2
Which storage practice helps prevent container sliding, falling, or collapse?
Explanation:
Stability in storage comes from restraining how loads are arranged. When containers are stacked, blocked to prevent movement, interlocked with neighboring units, and kept to a limited height, the whole stack behaves as a single, solid unit. This minimizes the chance of sliding, shifting, or toppling under vibration, braking, or handling. Storing on open shelves without constraints allows horizontal movement; piling loosely offers little friction or structural support; and hanging from overhead hooks introduces dynamic loads and requires special rigging—neither approach reliably prevents collapse. Therefore, stacking, blocking, interlocking, and limiting height is the best practice to prevent sliding, falling, or collapse.
Question
3
Which term describes a change in circuit state that is not governed by a clock?
Explanation:
State changes that happen without a clock are called asynchronous. In asynchronous circuits, outputs respond directly to input changes or events, not to a clock edge. This is in contrast to synchronous (clocked) designs, where all updates occur at defined clock transitions, ensuring timing coordination. A latch is a storage element that can be level-sensitive, often used in various timing schemes, but the question’s focus is on clock governance, which is captured by the term asynchronous.
Question
4
Which transistor terminal carries the main output current in normal operation?
Explanation:
The main current path in a transistor is between the collector and emitter, while the base provides the small control current. In normal operation, the collector current is the larger, output-serving current because it is amplified by the transistor (I_C is roughly β times I_B). The emitter current is the sum of base and collector currents (I_E = I_B + I_C), so it isn’t the primary output in typical configurations. The base is just the control input, and the gate is a control terminal in MOSFETs, not the main load-carrying path. Therefore, the terminal that carries the main output current is the collector.
Question
5
An FAA approved list of installed instruments or equipment that may be inoperative while allowing the aircraft to continue to be operated.
Explanation:
The main idea is the Minimum Equipment List. This is an FAA-approved document that lists which installed instruments or equipment may be inoperative and still allow the aircraft to continue flight, with specific limitations and conditions. The MEL is crafted to reflect safe operation with certain systems failed, outlining what must be repaired by when, and what alternate procedures or limits apply for dispatch. That FAA approval is essential, so phrasing it as an FAA-approved Minimum Equipment List precisely matches the description. The other concepts don’t fit because a standard equipment list doesn’t address allowable inoperative items, and while an MEL is often referred to simply as the MEL, the key point is that it’s FAA-approved and specifically governs inoperative equipment during flight.
