    I flew a Long-eze with the Aspen panel and it is very slick. Glass is great except that it is expensive and doesn't make the plane go any faster or farther or carry a greater load. The Cessna Skycatcher costs more than $150,000 and about one-third of the cost is the glass panel. The plane carries two people and cruises at about 100 knots. In 1974 I bought a Cessna 150 for $4,400 and it also carried two people and cruised at about 100 knots. $4,400 1974 dollars adjusted for inflation comes to $19,800, which is more than $130,000 less than the Skycatcher. You can also buy that 1974 Cessna 150 for about $20,000 today so instead of buying that Skycatcher you can buy a used Cessna 150 with steam gauges and use the left over $130,000 to buy a house.

    You can argue the relative benefits of the glass versus steam gauges and most of those steam gauges cost a lot of money and have moving parts that go bad and have to be replaced eventually so I can see your point about replacing the attitude indicator and directional gyro with the Aspen unit but a compass? cheap, and they last forever.

    Yes but... Those two glass panels have more redundancy and reliability than your "steam gauges" ever did. I am waiting and hoping (tho not in IMC) for my Attitude gyro to go so I can replace it with an aspen panel. It has a self contained back up battery and internal gps. So if everything else goes dark it will live another 30 min or so. 

    In the event it all goes... Pilot skills. No instruments in the situation you describe will most likely be fatal. That is essential what happens to Kennedy while trying to get to Martha's vineyard. He had instruments but must not have use or trusted them.
