IMPORTANT!! See the first sentence in 91.205. Read it carefully. "Homebuilts" don't have a "standard category" airworthiness certificate. Homebuilts have a Special, Experimental, Amateur-built certificate. 91.205 does not apply to your homebuilt, except as invoked by your letter of limitations. Typically, the letter of limitations only invokes 91.205 if your flying at night and/or IFR. This means that NONE OF THE ITEMS CALLED OUT IN 91.205 are required by regulations if you are flying day, VFR in an amateur-built plane. BTW, This is something I learned on the KRnet a few years ago.
Sec. 91.205 Powered civil aircraft with "standard category" U.S. airworthiness certificates: Instrument and equipment requirements.
