Readback: June 2017
I just got the April issue of IFR and your editorial (Do You Need EFIS?) exactly described my dilemma! My HSI needs to be repaired and Aspen has a sale on. To get the Aspen and install it is just a few grand more than repairing the HSI. I found Put It Together: DIY SOP in the May issue to be excellent. The creation of a personal SOP is a fantastic venture for any pilot and a very worthwhile, enjoyable and educational process.
