The two glass cockpit aircraft I have flown both had backup vacuum horizon. Also ASI & altimeter.
The engine doesn't stop when the battery goes flat.
The AC were C182 and DA40

Supersport,
Perhaps, but partial panel instrument flying is rather a more demanding skill set (especially when you are not IR/IMC rated
) than driving your car back from the pub. The fact that someone is legal-ish to drive doesn't mean that they are OK to go flying - especially in potentially marginal weather.
I mean this amount would have only just put him over the limit for driving and I bet there are very few people posting on here that haven't 'pushed their luck' a little when it comes to alcohol and driving.

To answer Rod1s point look at the features of the Porsche powered Mooney. One of the many reasons it did not do well was the complete duplication of the electrical system. That was done to meet the FAR requirements if there is no vacuum system. So multiple alternators, buses, batteries and flight instruments. A lot of weight to cart around and obviously a complex aircraft for your average aero engineer to maintain and understand.
So no, the average aircraft's safety is not much improved by going electric. Going solid state electronic - probably but we are still along way from that for certified equipment. (Corrected to add for certified equipment that people who work for wages can afford!)

Fg_Off_Max_Stout,
I couldn't agree more, my point was, that if/when we 'push our luck' with alcohol and driving and think we 'feel sober', which I am sure most can admit to doing at one time or another, we would effectively be 4+ times over the limit for flying, yet feel 'OK'.
This is why I feel it is stupidly easy for someone to unknowingly fly whilst over the legal limit. With the limit being so small it really wouldn't take much booze to tip the scales in the wrong direction (
a cap full of Listerine in the morning before you fly might even do some damage 
... or would that just effect a breath test 
?).

These items of equipment can be supplied with power by the
battery for at least 30 minutes. Economical use, in particular
of the Pitot heating, and switching off equipment that is not
needed extends the time during which the other equipment
remains available. During the 30 minutes period, the airplane
must be landed at a suitable airfield.
For cases in which the battery capacity is not sufficient to
reach a suitable airfield, an emergency battery is installed in
the IFR model, serving as an additional back-up system for
the attitude gyro (artificial horizon) and flood light. This battery
is switched on with the Emergency Switch. It lasts for 1 hour
and 30 minutes when the flood light is switched on.
I wonder what you have in mind keeps the FADEC computers alive when the power runs out?
Of course the FM also assumes the batery is healthy.

Fair enough - I did not realise you were referring to the DA40 without the tdi. Some one told me recently there are only a couple of those on the UK register but I have no idea whether that is so.
