What speed formula applies to a non-rotating tire with respect to pressure?

• A. V knots = 5.5 x square root tire pressure PSI
• B. V knots = 7.7 x square root tire pressure PSI
• C. V knots = 8.0 x square root tire pressure PSI
• D. V knots = 10.0 square root tire pressure PSI

Answer: (B)

The appropriate formula for calculating the speed of a non-rotating tire with respect to pressure is based on the square root of the tire pressure in PSI. The specific relationship defined by the formula allows for an accurate correlation between tire pressure and speed. The speed in knots is correlated to the tire pressure through a constant multiplier. In this case, the constant 7.7 serves as an established factor that allows one to derive the necessary speed from the measured tire pressure. This relationship is particularly important in aviation, where tire performance can directly impact safety and efficiency. The other options present multipliers that do not align with established aviation metrics for tire performance. Each of those constants leads to erroneous calculations regarding speed relative to tire pressure, which emphasizes the importance of using the correct factor for accurate assessment in flight operations. Thus, the chosen option accurately encapsulates the relationship dictated by aviation standards for non-rotating tires.
