What are the differences between and emulator and a simulator? Merriam Webster defines Emulator as “hardware or software that permits programs written for one computer to be run on another computer.” It defines Simulator as “a device that enables the operator to reproduce or represent under test conditions phenomena likely to occur in actual performance.” So an emulator allows one to run software or hardware on another computer while a simulator reproduces or represents conditions that may occur in real life. At Aviation Applications we create emulators that allow individuals to sit in the comfort of their own home and train on systems installed in an aircraft. These are not simulators that represent how an avionics system would perform in the air, but trainers that allows the individual to navigate through the pages or inputs of the avionics device, to understand how to input and display data required for flight. Most aviators learned on the standard six-pack of gauges and understand the basics of airmanship, but when they encounter a new device they must learn how to operate the device. This requires learning how to input data and retrieve data. Where is the data displayed? How is it manipulated? And how do you manipulate the device to display, or input the data needed to safely complete the flight. Emulators are used to teach pilots how to use the instrument. Emulators are used by the U.S. Military to train their pilots during flight school and during transitions to advanced aircraft. Time spent on these devices, reduces the amount of time in the air learning the new system. After all, once you are in the air, is not the time to try and learn the new avionics system. The time to learn is prior to the flight. It is safer to learn how to use the device on the ground rather than trying to learn in the air and fly at the same time. Save time, money and possibly your life by using an emulator. Time spent training on the ground will provide you a safer and more enjoyable flight. Remember, takeoffs are optional, but landings are mandatory!
