91.205 compass requirement

Does the ClearNav bearing display satisfy the magnetic compass requirement of FAR 91.205?

91.205 does not apply to almost all gliders.

I could not find a FAR that exempted gliders. Can you point me to the correct FAR or FAA ruling?

Try the title:

Powered civil aircraft with standard category U.S. airworthiness certificates: Instrument and equipment requirements

Unless the glider manual or TCDS lists the compass as required.

For what it's worth -

Almost none of the new gliders displayed at the convention had compasses.

I was told that was because the FSDOs had said that the GPS driven displays were adequate.

I understand there is "chapter and verse" for the regs supporting that but I don't know what it is.

The question was "the magnetic compass requirement of FAR 91.205", not the POH. Clearly there is no such requirement for gliders.

How does 91.205 apply to self-launching gliders? Or to touring motor gliders?

They are registered as gliders?

My motor glider is registered as a glider, Jim. But 91.205 does not use the word 'glider' it refers to 'Powered civil aircraft with standard category U.S. airworthiness certificates'. I have a self launcher, so would argue that although my glider is an aircraft, and is powered, the power is incidental to the flight, so its not a 'powered aircraft' as the FAA would define it. See also the FAA definition of a glider at the start of the FARs. I'm just guessing at the FAA's view here. But a touring motor glider might well be considered a 'powered aircraft' by the FAA, I'd guess, since its designed to cruise under power for a significant part of any flight.
