Consider the general aviation propeller-driven aircraft, with a weight of 2,900 lbs, in steady level flight through a constant horizontal headwind of 25 ft/s. (a) what is the expression for the power required to maintain steady level flight at an altitude of 14,000 ft? plot the power required to maintain steady level flight as a function of airspeed. what is the airspeed at which this required power is a minimum? what is the minimum value of the power required to maintain steady level flight? (b) if the elevator deflection is 3 degrees and the throttle setting is 80%, what are the possible flight conditions for which steady level flight can be maintained at an altitude of 14,000 ft? for each such flight condition, what are the airspeed and the angle of attack?
