You can also get a good feel for the trend of the tape by how fast/slow it's
moving in any given direction. J. Mac McClellan wrote about tapes in a
recent column in Flying (he likes tapes but he was complaining about the
lack of speed markers). Tapes are no doubt the result of many studies by
NASA and other entities (DARPA maybe?) so I would see if you could dig up so
info on their line of thinking.

But one thing bugs me -- the tapes.

I can't for the life of me figure out what all the manufacturers
have opted to provide flight information in these electronic
tape formats. Has this been proven to be more effective, more
ergonomic, easier to interpret, etc?

Fly with the tape presentation awhile before you start worrying. With a
tape, you can see the height and the relationships between tapes at a
glance,
without having to worry about where a needle is pointing. As long as the
tape
is green, you're in good shape, but if it turns red, then you know
immediately that you've reached a limitation. If all you've ever seen is
a
dial, then you probably prefer a dial. But if you get used to tapes, then
you may prefer it.
