Do you use GPS at work?

I work with GPS almost all the time at work. I install and certify aircraft GPS units into all sorts of aircraft. Aircraft GPS systems are quite a different breed than typical handheld units. Aircraft GPS units are integrated into all sorts of different systems on board aircraft: Autopilots, Communications, other navigation systems and indicators, Air Data computers, Fuel flow totalizers, large screen moving maps and EFIS systems, Etc. Most Aircraft GPS systems use analog, and RS232 and Arinc databusses, and large bundles of wires to make it all work. Aircraft GPS units have built in databases which contain the indentifier for each airport and NAVAID, the communications frequencies for each airport, special airspace boundries, and predefined routes to be followed for approaches to each airport. And of course, lots of FAA paperwork to make it all legal.
