Well I purpurchased one, and tried it yesterday. Brilliant.
Easy to read, and use the touch screen.
The synthetic vision is the star...
Flew down amongst the hills, and it very accurately represented the terrain, warned of conflict with colour, and followed pitch roll change of direction really well.
Flew a long final to the threshold of 27 Nadi, and it perfectly aligned with what I was seeing out the front.
I honestly think this might save someone who went IIMC, and is not confident on instruments.
