All the aircraft I'm looking at have an HSI. The plane I
fly with my boss has an RMI on his EFIS, but no on the
co-pilot station. So far, we've never used it.

If you have an HSI, you certainly don't want to downgrade to an
RMI. The HSI gives you much more information and is easier to
interpret.


Thanks, Stan.

That's what I though, and I notice many of the more elaborate HSI's have RMI
indicators. I'm just wondering what the big deal is in having both, as many
aircraft do.

My original point is that RMI's seem more common nowadays, but were somewhat
rare when I began my hiatus from flying in 1989 (until this past summer). I
was under the (mistaken??) assumption that they made NDB approaches easier.

As I said, so far, I've not seen the boss use his.

I would like to know the whys and HOW's in any case.

Tom
