You have to read the manual to discover the vertical speed indicator can be used as a vario
(using electronic Total Energy compensation - no probe), or as a standard, uncompensated VSI.
No audio, but probably at least adequate as a backup to the primary vario. That makes it a
3-in-one combo: ASI, ALT, Vario. That's good news for small panels, and a lot cheaper, too.

Looks like an excellent concept but does it have any sort of approval? I can't see any mention one way or the other on the LX Nav website or in the manual.
