Answer is pretty simple. What makes it work? If loss of electricity will mean loss of the instrument then that’s the reason not to replace your spinning mass gyro with this. There are a couple of other instruments on the market similar to this and they are very tempting but they have the same drawback. The steam gauges are there for only one reason - save your ass if everything that can hit your avionics does so.

Subject: [LML] Steam Gauge Replacement

Gents: Just saw this in "Sport Aviation." I have two Cheltons and a backup
steam ADI. Seems this little unit gives Airspeed and Heading and Altitude and
VS, as well as attitude.

Any reason to not replace my single purpose steam attitude indicator with
something like this for a thousand bucks?

Cheers,
