How many equipment plates does the main portion of the engine have?

• A. 1
• B. 3
• C. 4
• D. 2

Answer: (D)

Equipment plates are the fixed mounting surfaces on the engine’s main section used to attach essential accessories and keep things properly aligned. In the standard engine layouts covered by this material, there are two of these plates—one on each side of the main portion—providing symmetrical mounting points and balanced support for attached components. That’s why two is the correct count: it ensures proper alignment and load distribution. A single plate would be imbalanced and provide insufficient mounting, while more than two isn’t typical for the main section in this context.
