Flight Inspection System (FIS) is used to test and inspect the navigation aid systems by using a real airplane flying on the navigation routes. It carries standard navigation receivers for all navigation system under test. The test is performed by comparing the receiver's readings with another reference for each navigation system. The FIS system was implemented and installed on IRAQI AIRWAYS airplane as a flying laboratory FIS and the test was started by using the laboratory early in the year 2002. The test on this airplane is performed by experts (air navigation inspectors) but this test is done manually by recording the reading of the receiver readings and the physical reading corresponding to the instantaneous position of the airplane received from a ground reference station. The project presents the FIS system together with the required equipment for data acquisition and data processing. The project aim is to automate the process of online continuous reading for each navigation system, as well as the check of reference position supplied by the ground station. The result corresponding to each test is calculated instantaneously and given to ground service staff to correct the navigation transmitter stations. The automation of the FIS laboratory was implemented through computerizing the process, by interfacing a test computer to each navigation system and with reference check from ground station. The computer then calculates the results of the test and indicates the error to the inspector. The FIS computer also provides graphs corresponding to the movement of the aircraft for each navigation system and the corresponding actual position indicating the error online. The test finalized by averaging the error to give a single number corresponds to the deviation angle for each test. A software package was written to provide all control signals and monitor the reading of navigation aid systems. The software provides the graphs and shows the result for test for each navigation system, under the windows environment that makes the inspector monitors and controls the test in a simple mouse driven menus. The system successfully tested and shows a considerable improvement for the manual test in the time and accuracy by canceling the human errors. Finally, the project initial step was to replace a data entry for Being 727 from an old paper punched tape to a personal computer. The old system was very slow, whereas the proposed system had many good features like speed and large storage.
