Name several types of electrical devices that would be considered intermittent loads on an electrical system?

• A. Landing gear motors
• B. Radio transmitters
• C. Cowl and wing flap motors
• D. All of the above

Answer: (D)

Intermittent loads are electrical devices that draw significant current only during specific operations or moments, not continuously. Landing gear motors are powered only during gear extension or retraction, so their demand on the electrical system appears in bursts rather than all the time. Cowl and wing flap motors follow the same pattern, activating only when adjustments to flaps or cowl flaps are needed. Radio transmitters consume notable power when they are transmitting, with only minimal standby draw otherwise, so the main load occurs during operation rather than continuous service. Because each of these devices draws substantial current only during particular actions, they all fit the description of intermittent loads. All of the above.
