Graphical representation of digital compass and altimeter / Siti Zuraini Harun

This project describes graphical representation; the inputs received are defined from the digital compass and altimeter. The input readings from digital compass represent the coordinates of a flight in terms of heading, pitch and roll while altimeter gives the readings in height. This project mainly presents the development of a program to simulate data related to digital compass and altimeter. The results displayed graphical representation of the digital compass and altimeter in a glass cockpit. The functions of the primary instruments in a glass cockpit are combined into one display which is the Primary Flight Display. The graphical display provides the most realistic Primary Flight Display currently available for flight simulation. In order to represent those inputs obtained from digital compass and altimeter, few objects are drawn to realize the graphical representation. Basically, the center of the screen displays the reference plane on the ground. The graduations above and below the horizon show degrees of pitch up or down of the nose of a flight. On the right side of the display, there is an altitude tape that will pop up a reading obtained from the altimeter in terms of height. Below the artificial horizon, there is a compass card which displays the true heading obtained directly from digital compass.
