UnrestrictedClimbAnalysis.m• Main program to execute the descent analysis• Employs Matlab Ordinary Differential Equation solver (ODE15s)• Function Calls:• fclimb_06.m - function that contains the equations of motionof the aircraft in the descent phase• densityAltitudeoffISA.m - function to estimate theatmospheric conditions for both ISA and non-ISA conditions• drag03.m - function to estimate the aircraft drag at any altitude(h) and Mach number (M)• thrust_calculation.m - fundtion to estimate the thrustproduced by the engine for any Mach number and altitude (h)conditionVirginia Tech - Air Transportation Systems Laboratory34
UnrestrictedClimbAnalysis.m• Inputs to the Program• Aircraft file to be used in analysis (line 36)• Speed profile. Climb speed profile specified as a table function inthe aircraft file (lines 29 and 31 in aircraft file)• Initial aircraft states (lines 38-42 in main program)• altitude, mass, distance traveled along path and distancetraveled along a flat earthVirginia Tech - Air Transportation Systems Laboratory35
