Abstract:
1. An emulator for simulating ARINC-429 data output by an Inertial Navigation System on board an aircraft, comprising: (a) a plurality of slider controls appearing on a display screen, wherein said plurality of slider controls allow a user to adjust emulated values for position, direction and velocity data for said aircraft which is normally output by the inertial navigation system on board said aircraft; (b) a computer having computer software for controlling handling and interpretation of the emulated values for said position, direction and velocity data for said aircraft; (c) said computer software setting range limits for said slider controls, providing initial values for said position, direction and velocity data for said aircraft, and initializing time and date display text (d) said display screen displaying the initial values for said position, direction and velocity data for said aircraft and said time and data display text; (e) said computer software, in response to adjustments of said slider controls by said user, generating the emulated values for said position, direction and velocity data; (f) said computer software generating a data output thread comprising ARINC-429 data which has the emulated values for said position, direction, and velocity data included therein; and (g) said computer software initializing an interface board within said computer, wherein the interface board within said computer receives the data output thread generated by said computer software; and (h) said computer software, after initializing said interface board, outputting the data output thread generated by said computer software to said interface board within said computer.
