← ScienceWhich mechanism limits accuracy estimating drone airspeed using pitot-static differential pressure based on Bernoulli's equation?
A)Boundary layer flow separation✓
B)Compressible flow effects
C)Sensor calibration drift
D)Atmospheric pressure gradients
💡 Explanation
Boundary layer flow separation at the static port introduces errors; therefore, airspeed is under-predicted because flow separation alters the pressure distribution affecting differential pressure readings, rather than compressibility which matters at high speeds.
