Recent discussions about EFIS hardware compatibility, software updates and feature requests, etc. now have me wondering about what is considered "best practice" for designing a glass panel. The RV-14 airframe could easily last over 30 years with proper maintenance (yes I've primed EVERYTHING in the airframe). iPhones and iPads don't last much beyond 4-5 years. How long will a Dynon or G3x system last? I would have to think any glass I put into a panel today would be lucky to last 5 years before replacement is required. Is there anyway to make that replacement less painful? Is there a wiring scheme that should be used that would be plug comparable with future replacements? Should I just go with steam gauges? What commitment do Dynon and Garmin have to future support? Are there standards that will be supported for the next 30 years like CAN bus or ARINC? Can any manufacturers speak to what their plans are for 30 year life span support?
Engines are life rated for some number of hours of operation and we all set aside funds for engine rebuild/replace as an ongoing expense. Maybe avionics should have a similar rating so we can at least understand the costs involved.
This stuff is a significant portion of the cost of the airplane and it would be nice to mitigate future expenses if possible. Any ideas?
