I bought an aircraft fitted with a glass display and have to make the observation that I removed it and fitted conventional steam panel.
The reasons I did this, rightly or wrongly, is that I did all my IMC training and experience on PA28s and Club Cessnas. I decided that in an emergency I would be better seeing a display that I was 100% familiar with rather than a glass one where a certain amount of 'reasoning' would have to be done. It's when everything starts to go wrong that an easily understood set of instruments will come into its own. I'm not saying anyone else should do this, its just something to consider.
