What does the acronym SRA stand for?

• A. Shop Replaceable Assemblies
• B. Sensor Read Activity
• C. Servo Rotation Assembly
• D. System Remote Access

Answer: (A)

Shop Replaceable Assembly refers to a modular component that is designed to be removed and replaced in a maintenance shop rather than repaired in the field. This labeling helps maintenance crews know where the fault should be handled and ensures that testing and calibration occur in the proper environment. In practice, an avionics subsystem may consist of several SRAs that can be swapped out as a unit; the faulty part is sent to the shop for repair while the good one goes back into service. This is distinct from a Line Replaceable Unit, which is intended for rapid field replacement, allowing aircraft to return to service quickly. The other options don’t align with standard avionics terminology: Sensor Read Activity and Servo Rotation Assembly aren’t recognized terms for replaceable units, and System Remote Access refers to remote connectivity rather than replacing hardware.
