What is the difference between the static pressure and the stagnation pressure when the aircraft is stationary?(a) Infinite(b) Any random value(c) No difference(d) Static pressure |

Answer» Correct option is (d) Static pressure To elaborate: when the aircraft is stationary, the pressure sensed by the static port is the free stream air pressure and the stagnation pressure ports are zero. Since the aircraft is not moving stagnation pressure is zero and hence the difference between the two values is the static pressure. |
