Chapter 22 – Flight Data Instrument

Well, since I’ve been researching out my avionics & instruments alongside my engine components, I’ve started scheduling out some purchases for some of the panel avionics that I know I’ll for sure be installing.  One such item I serendipitously stumbled across in my research is the Flight Data Systems AFP-30 Air-Data Fuel Computer.  This guy was developed by an RV driver to add some more data points that he wanted to see in his cockpit.  After researching this out and cross-referencing it in a matrix I have to compare all the functions of all possible avionics and instruments, I decided that this was definitely going on my instrument panel to provide me both unique & back-up instrument capabilities.
