At their price point aren't they considered more as a vacuum instrument replacement? There are tons of vfr only airplanes that don't care or need that integration. It is however something that should be considered. It is only competition to the G5 in the vacuum replacement market.
I agree about being a vaccum replacement. Maybe not even replace - yet. Instead, I would think of this as a companion to a G5 installation.
I don't agree that this is just for VFR panels. It's a certified instrument. The no VOR/ILS argument I can see in some cases where there are actual GPS outages. But I haven't encountered a GPS outage in 16 years of flying. Compare that to experiencing two vaccum system losses and three gyro instrument failures. Which is more likely? I mean, you can't prepare for everything, can you? What about bird strikes? Those are more common than GPS outages.
"But what if I lose my GPS"... I know
@Canuck is going to ague this.
From AV-30 FAQ:
Does the AV-30 support a magnetometer?
By default, the AV-30 is a non-slaved DG. The good news it that this reduces installation complexity dramatically (
no GPS antennas required, no remote mount magnetometers, no field mapping, no calibration). Power and ground are the only required connections when the unit is installed as a DG. The bad news is that it operates the same as a non-slaved DG. On power up, a minor heading adjustment will be required. (last known heading is saved). During flight, it will require minor corrections.
In other words, it works exactly the same as your vaccum gyro. There will be some precession. I'm willing to bet it's much more stable than a compass. So saying it's for VFR only - I disagree.
Per the Garmin G5 installation manual, it is certified for IFR in certain configurations. Being that that the turn/slip is still require in all the pictures below and the AV-30 is a certified attitude / slip instrument, I think you can directly replace that gyro.
So I see the AV-30 as a backup system for vaccum failure, OR backup for a G5 or Aspen E5 failure.
One could argue that the electric gyro is more reliable. However, consider actually having to fly IFR partial panel. We all like to think we can - but can you? Really? In all situations? Statistics alarmingly say "no"!
Another market (albeit small market) is to have copilot instruments. The AV-30 is an all-in-one instrument set that does the job for inroute.
