What is an advantage of Internal combustion engines?

• A. More horsepower per pound of engine weight.
• B. Lower fuel costs.
• C. Quiet operation.
• D. Maximum airspeed, altitude, climb and descent rates.

Answer: (D)

Internal combustion engines deliver a lot of power for their weight, thanks to the energy-dense fuel they burn and the ability to produce high sustained power. That level of power directly supports higher top speeds and stronger climb/descent performance, which is why the best choice points to maximum airspeed, altitude, and climb and descent rates. Quiet operation and lower fuel costs aren’t typical advantages of ICE power, so the strongest benefit in this context is the enhanced flight performance from more available power.
