The item to note is that the FAR's do not apply to an experimental as they are type certificated. To allow an experimental aircraft to operate the work around is the operating limitations which is issued to each aircraft when it receives its airworthiness certificate.9. Aircraft instruments and equipment installed and used under FAR 91.205 must be inspected and maintained in accordance with the requirements of FAR 91. Any maintenance or inspection of this equipment must be recorded in the aircraft logbook and maintenance records.
I asked DAR, who did airworthiness inspection of my gyro, if I have to have magnetic compass onboard, his responce was exactly what I posted above: "FAA does not require ANY instruments to be installed on experimental aircraft for VFR flights".Technically that may be true but I think they are making DARs put a few things in the operating limitations. Depends on the aircraft's capabilities, I guess.
