I put an RMI into our panel (a plug-in module for the Argus actually -
thanks Ebay) just for flying DME Arcs.

What else are RMI's good for? The RMI has two needles, each of which can
"point" to a navaid. As mentioned, this is good for identifying
intersections (although I confess I prefer DME and one nav source). Better
yet, you always know radial/bearing from/to a VOR/NDB. Good for locating
yourself on the map or flying a missed approach when you need to "find the
VOR" while climbing and turning. Just follow the needle.

Personally, I'd invest in an HSI before I invested in an RMI. I'd invest
in
an Argus 7000 before I invested in an RMI (these things are amazing, and
amazingly cheap these days - $700 on EBay right now).

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.


I was wondering if I should add one to a bird I plan to buy?

Thanks
