Which manual governs avionics equipment and avionics support equipment when there is a difference?

• A. Aeronautical Engineering Maintenance Manual
• B. Coast Guard Electronics Manual
• C. Integrated Logistics Support Plan
• D. ACMS

Answer: (A)

In avionics maintenance, the standard reference for how avionics equipment and the avionics support equipment interact, and how to handle any differences between them, is the Aeronautical Engineering Maintenance Manual. This manual provides the authoritative procedures for maintenance, calibration, testing, and alignment of avionics systems, including the tools and test equipment used to support those systems. It sets the criteria for acceptance and describes how to resolve discrepancies between installed equipment and the supporting test and calibration gear, ensuring consistent, correct maintenance practices.

The Coast Guard Electronics Manual covers general electronics procedures but is not the primary authority for governing differences between equipment and its support equipment. The Integrated Logistics Support Plan focuses on logistics and life-cycle support, not the specific maintenance procedures. The Aircraft Condition Monitoring System deals with health monitoring and fault reporting, not the governance of how to address differences between equipment and support equipment.
