Pitot Static Blockage Effect
A precise tool.
What is the Pitot Static Blockage Effect & How does it work?
The Pitot static blockage effect occurs when the pitot tube and static ports are not perfectly unobstructed, leading to inaccuracies in airspeed measurements.
\Delta V = \frac{2}{3} \cdot C_b \cdot V_{true}
\Delta V = blockage error in airspeed, C_b = blockage coefficient, V_{true} = true airspeed
The blockage coefficient, \(C_b\), depends on the size of the obstruction relative to the pitot tube and static ports.
