What is the total horsepower at which an engine rated for 250 horsepower operates at 85% of its power?

• A. 212.5 horsepower
• B. 225 horsepower
• C. 200 horsepower
• D. 175 horsepower

Answer: (A)

To determine the total horsepower at which an engine rated for 250 horsepower operates at 85% of its power, you need to calculate 85% of the engine's full rated horsepower. First, convert the percentage into a decimal by dividing by 100: 85% = 0.85. Next, multiply the engine's full horsepower rating by this decimal: 0.85 × 250 horsepower = 212.5 horsepower. This calculation shows that when the engine operates at 85% of its capacity, it produces 212.5 horsepower, which aligns with the answer choice provided. This understanding of percentage calculations and their application in real-world scenarios, like determining the output of an engine based on its rated power, is key in aviation maintenance and engineering contexts.
