Com" Subject: RV8-List: EFIS & IFR SUSPICIOUS_RECIPS --> RV8-List message posted by: "Noel & Yoshie Simmons" It appears that these FAA regs alone are not enough. My FAA representative and our FAA DAR (who is a homebuilder, too!) has told me that it is not sufficient to follow all the rules; instead, an FAA rep or DAR needs to positively approve it. If the instrument avionics are not TSO'ed or equivalent, then they will not sign off on it. Period. Without the FAA positive approval, even if you do not violate any FAA regs, you cannot fly IFR. I think the FAA inspectors/DAR do not want to risk their jobs, and there is no specific instruction to them that non TSO'ed instruments are ok in experimentals, so they just refuse. If you can find one FAA inspector/DAR who is willing to sign off e.g., a bluemountainavionics EFIS for IFR use, then please let me know. Sincerely, Noel Simmons
