Are approach charts/plates really usable and safe to use on a PDA? I'm
asking specifically about the small screen size (let's ignore the fact that
it runs on batteries etc). It seems like the Jepp size is about right. I
can't imagine either: 1. shrinking the page into a PDA's screen, or 2.
scrolling around while on an approach.

What's wrong with scrolling? Do you really need to see the entire plate
when you're on the approach? I agree that you *do* need to be familiar
with it. That means you should certainly scroll/zoom around the whole
thing before starting the approach. Once you've begun, however, I'd
expect that just being able to see the area around the current location
(at a user-selected zoom level) would be enough. Maybe not. I haven't
tried it.

I'm using a pen computer with a nice big screen for my experiments these
days. I'm much more comfortable with that size.
