Why is EMI bad news in an airplane as opposed to anywhere else?

Hi Jim.

I will be building the PWM board and will simply test it. As you have often
said, there is a reason why we put that one word promanently in our
aircraft. If it looks and sounds fine on my workshop bench, I'll take it to
an airplane and fire it up there. If that's ok, its going into the plane.
And though I am not at all a fan of varying the current through LEDs, I will
take a look at the variable current version. 317s are easy enough to get at
RadioShack, they're plenty cheap and there's lots of time in which to do the
work.
