The pitot static system of Cessna 172 is used to determine theindicated airspeed at which the aircraft is flying. Determinationof airspeed on the airspeed indicator is based on using sea leveldensity in the Bernoulli’s equation. If the pressure differencebetween the pitot tube on the wing and the static pressure probe onthe fuselage side of the airplane is 40.9 lb/ft^2,determine the indicated airspeed of the aircraft inknots. If the aircraft is cruising at 5,500 feetin a standard atmosphere, determine the true airspeed inknots.
