I was planning on mounting my ipad to the back of the seat and using the Levil AHRS with pitot static imputs to provide a full 'synthetic vision' display using certain apps. The ipads built in gps allows for course guidance, route tracking, and a reference for the synthetic vision display. The front seater would still need to work freqs and squawks but in the mean time there is plenty information displayed for the back seater to maintain aircraft control and navigate even through IMC. Additionally, I'd like the back seater to control the mp3 music selection into the audio panel for their entertainment on trips. While I prefer to fly using outside references, I think I would be comfortable flying from the back with a less experienced guy up front using this type of display if I was going to take friends flying. Thoughts?
