than NACO, but I don't know how their software is for accessing the charts.

I think that at the root of all the distributions is a collection of PDFs.
When I was considering something similar I converted a few to images at a
resolution suitable for zooming on a PDA and I think you could fit the
whole shebang on a 1G card.

I absolutely wouldn't want to try it with a stock PDF reader, though. I
want an app that's going to know about the various regions of the plate
and be able to zoom to them quickly (with a single hardware button press,
for example).

Plus a custom app could use a textual database of things like elevations
and frequencies so that they could be presented in a "native" display
rather than as part of the rendering of the plate.

Control Vision also offers their product Pocket Plates, will display

In forums where I've seen Pocket Plates discussed people fell into two
categories: They had seen it briefly (in a review, on the web) and thought
it looked neat. Then there were users, who seemed to uniformly dislike
the product and some who had grudges against the whole company. Scared me
off, anyway.
