2. The average value method for determining the range of a turbofan aircraft is given by equation Q 2.1 below: AW Ct Dav Equation Q2.1 - Average Value Method for Range R = E. V = -V a) Define the term 'aircraft range' b) Derive equation Q2.1 for an aircraft operating on a constant AOA and altitude flight schedule into the equation below, stating any assumptions you have made: R= 2-(/) () (~) (-3) ps Equation Q2.2- Constant AoA & Altitude c) Hence, or otherwise, determine the range for a Cessna Citation X+ operating at its maximum L/D ratio at an altitude of 39,000ft, with the parameters shown in table Q2.3 Property Wing Area (ft2) TSFC (hr) Drag Polar Value 527 0.70 CD= 0.019 +0.044CL Empty Weight (lbr) 22131 Fuel Available (lb) 9 700 Table Q2.3- Cessna Citation X+ Parameters
