Which phenomenon causes increased fuel burn when an aircraft exceeds its designed airspeed?

💡 Explanation

Increased airspeed causes a transition to turbulent flow, whose effect on skin friction (drag) the Bernoulli equation underestimates; therefore fuel usage rises to overcome this increased drag, rather than induced drag alone predominating at higher speeds.
