12 Discussion of Results This project has created a graphical user interface (GUI) to aid in the creation of text files to import into the 3DLinx worlds used by the Cal Poly Flight Sim. Following are instructions for its intended use and known issues to avoid. Chase User’s Guide To launch the program, begin MatLab and ensure that it is in the working directory or in the MatLab search path (under ) and type at the command prompt. This will bring up a GUI with multiple fields for data entry (Figure 2). Figure 2: Chase Window
13 Begin by inputting the desired initial conditions in the first six fields for X and Y displacement, altitude, heading, airspeed and bank angle. These will determine the starting point for the aircraft, and if the 3DLinx object is set to loop, it will return to this point at the end of its flight path. After the initial conditions are set, the user must designate a flight path for the aircraft. This description may be entered manually in the field or input through use of the and tools. Path descriptions are made up of several segments, each described by entering where: A – The letter or , denoting a straight or a turn If the section is a straight, then: B – The letter or , denoting a value of time in seconds or distance in feet. X – A number value, corresponding to the state of B. C and Y – Will be blank, resulting in an input of . If the section is a turn, then: B – The letter or , denoting a value of bank angle in degrees or g loading. X – A number value, corresponding to the state of B. A positive value corresponds to right turns, a negative value to left turns. C – The letter or , denoting a value of time in seconds or heading change in degrees Y – A number value corresponding to the state of C. Note that each segment must end with a semicolon , including the final segment.
