So our plane has got a new factory reman engine in Year 2; Shiny new paint in Year 6... finally time to bring the panel up to 2016.
The minimum requirements are "must have IFR GPS approach capability" and panel is so old, assume nothing would be compatible with whatever we install (e.g. we'd need accompanying indicators, etc.). 2020 compliant with upgrade would be nice, but not necessary.
Assume some DIY for panel prep, but professional install required.
How would you meet this requirement for:
10 AMU's
20 AMU's
30 AMU's
40 AMU's
