Aerospace Logic Fuel Gauge

[Scott G.]

Does anyone have any information whether Aerospace Logic's Fuel Gauge is a
primary gauge replacement, or if the original fuel gauge would still need to
be kept in the airplane? Application would be a Cessna 206.

Thank you,
Scott G

This was just discussed on CessnaPilots.org, and the consensus was
that they are still trying to get an STC. Advice was that since Field
Approvals are such a big pain in the ass, that waiting for a while is
in order.

Contact the vendor...

Ok, thanks.

I am sure they have an STC for the gauge and in the STC quite a few of the
typical general aviation aircraft are included. It does not specifiy in the
STC whether or not it can be used as a replacement gauge though. Some of
the EI gauges such as Oil Press/Temp can be used as replacement gauges, and
others such as the 4/6 cylinder engine analyzers cannot. I wish the
manufacturers would be a little more clear in their STC's. The STC for the
Insight analyzer it specifically states it is for additional information
only and cannot replace a primary instrument. In the EI STCs they really
don't say either way, but a call to EI cleared that up.

As far as upgrades go, the EI oil press gauge uses a remote sender, so you
can eliminate the oil line into the cockpit. Also in the Shadin fuel flow
STC it states it can be used as a primary fuel flow gauge. Maybe if you
have one of those Cessna split gauges, you can eliminate the fuel line into
the cockpit, you would just have to either label the old fuel flow inop? or
find a suitable replacement for the manifold pressure and remove the old
gauge entirely.

Thanks,

EI will send you a copy of a 337 to get their fuel gauge approved as a
primary replacement. You use all the rest of the Cessna stuff and wire it
to their gauge. The Cessna Pilots Assoc website has lots of Cessna single
owners who have recently made the change. Mac Speed at EI is the guy you
want.

We tried that originally actually. We installed the EI gauge and went
through the calibration process (empty fuel tanks, fill 5 gal, take reading,
repeat for both sides) needless to say, took a while. EI had three
previously approved 337s on their website. We submitted the 337 and the
previously approved ones in a hope it would help the process along. Of
course it came back. The FSDO stated they were no longer able to do this
field approval and said we would have to go through engineering to get it
done. In the mean time Aerospace Logic was able to obtain a STC for their
fuel gauge. EI said they were working on a STC but it wasn't a priority and
couldn't predict when it would be obtained. We have a quite a few EI gauges
and they have been a great company to work with. From needing wiring
harnesses (Pawnee has a huge nose) to needing instruments remarked, they are
quick and very reasonable.


Thanks for the ideas,

I hadn't heard that they had an STC for this gauge. This would be big news
and would be widely reported. Somebody else in this thread said that you
still had to get a field approval for the AL unit..

If you go to www.aerospacelogic.com it will allow you to download the STCs.
Also on the home page which I should have read more carefully, they state
STCed as primary gauge replacements.

Scott,

Can't be specific about the 206, but my ramp neighbor recently
replaced all of his OEM gauges with the Aerospace Logic gauges under
the STC. His old Piper OEM gauges were removed, so I would assume
that the STC allows for direct replacement. This was on a PA-28

Hey, is it allowed in our plane? We have a PA-28-180. The stc docs
lists PA-28R-180 and PA-28S-180 but not PA-28-180.
