A turbo-normalised engine maintains sea-level manifold pressure to 15,000 ft. Compared to a naturally aspirated engine at that altitude, the turbo-normalised engine will produce:

• A.The same power as at sea level only if full throttle is used
• B.About 50% of sea-level power, since propeller efficiency is halved
• C.Approximately sea-level power, since it maintains sea-level manifold pressure
• D.About 120% of sea-level power due to the turbocharger boost
