Which outcome results when Reynolds number exceeds limit in aircraft pneumatic de-icing boots?

A)Laminar flow becomes turbulent
B)Boot inflation cycle accelerates
C)Vacuum stall pressure increases
D)Bleed air temperature decreases

💡 Explanation

Turbulent flow is induced because the Reynolds number exceeds the critical transition point during pneumatic boot inflation, therefore laminar flow transitions to disruptive turbulence causing impaired boot performance, rather than predictable inflation.
