Hi Bret-

airworthiness category.

I concur. This ties in directly with the conversation over at aeroelectric
where the topic is a particular fed requiring a 337 for GPS installations.
The only thing on an experimental that is actually required to be TSO'd
(certified) is a GPS that is used for terminal ops. Nothing else. Now,
realistically, if one chooses to build their own com radio or transponder,
proving TSO compliance could be a bit problematic. Actually GAINING a TSO
is a separate issue, and relates to marketing and use in the certified
world.
It's curious how we, as a group, can get so caught up in the details of the
bark of the particular tree we are looking at that we forget which forest
we live in.
As an aside / FYI, and if I recall correctly, one of the composite props I
was familiar with had a metallic spar that ran virtually to the tip of the
blade, and the other had wire mesh embedded in the outer strata of the
blade. Both had nickel leading edges for rain / FOD protection, but also
provided a conducting path for lightning. One of the two airplanes was a
lightning magnet, and our company experienced many strikes, with no prop
damage that I recall. Rudders, on the other hand.....
Do not archive this particular ramble
