As we’ve been reporting, prices for some retrofit primary EFIS systems have dropped to the sweet spot of around $5000 or less. This is thanks to a new regulatory certification process that sidesteps the pricey and time-consuming TSO process in favor of an STC. Aspen Avionics has populated the field with over 20,000 Evolution EFIS displays over a 10-year span and is the latest to offer a budget-based EFIS with the $4995 EFD1000 E5 Dual EFI.
But Aspen also offers other displays with more advanced features at higher price points, which muddies the buying decision. For this report we put the new E5 on our test bench to see how the feature set compares with other Evolution displays.
