I await everyone's opinions. I agree with the premise that I think Dan has;
that it should be possible, and practical to develop a gasohol safe
airplane. "Some will no doubt shout, you will crash and burn!"
This could be an interesting discussion.

Since Embraer has an alcohol fueled aircraft in production, it is
obviously possible.

The question then becomes what would it take to retrofit an existing
aircraft?


My understanding is that multi-fuel engines were the norm
in Brazil for a while. These could run on straight gasoline or
high alcohol content fuel. The early ones had a manual
switch, but later models used a fuel density detector
which automatically adjusted on the fly.

The last I read, Brazil was moving towards tighter
standards for auto fuel, and the multifuel engines
were being phased out.
