RE: Light-Sport Aircraft Yahoo group Re: Avionics Equipment

That is only true if words have no meaning. An "electrical system" implies
directly the sourcing and grounding of electrical energy. The 447 without
the coils hooked to anything does not source and ground electricity. The
word "system" alone implies a complete connection, otherwise the English
word would be "pieces".

If they wanted to wordsmith for a partial system, "...with an engine-driven
electrical system" would be replaced with "...with any portion of an
engine-driven electrical system".

How about a Piper Colt that had a voltage regulator, but no alternator,
added to the plane when it was certified? Since it would then have a portion
of an electrical system, as does the 447 with disconnected coils, would it
need to have a transponder?

Rotax 447 has an engine driven electrical system. Its has a lighting coil
comes with the engine and can be hooked up using a rectifier.

wind-driven generator to keep the battery charged.
