    INNOCENT GLOBAL 0.0969 1.0000 -1.4111 --> Avionics-List message posted by: <bakerocb@cox.net> Here's a question asked by an AOPA member who contacted our aviation services staff through the AOPA Pilot Information Center. Test your knowledge. Question: I have an IFR-certified GPS in my aircraft. Is it required that I make an entry into my aircraft's maintenance logbook every time I update the database? Answer: Yes. The FAA, under 14 CFR Part 43, Appendix A, defines what is considered to be a major alteration, major repair, and preventive maintenance. Updating a GPS database qualifies as preventive maintenance that a person holding at least a private pilot certificate may perform in this section. The FAA, under 14 CFR 91.407(a)(2), states that a maintenance record entry must be made for any aircraft that is approved for return to service after undergoing preventive maintenance. The entry should include, as stated in 14 CFR 43.9(a), the date of completion of the work performed, description of the work completed, your signature, pilot certificate grade, and certificate number. For additional information on maintenance logbook entries, see AOPA Online.

    INNOCENT GLOBAL 0.4986 1.0000 0.0000 --> Avionics-List message posted by: <bakerocb@cox.net> Responding to an AeroElectric-List message previously posted by: "Hinde, Frank George (Corvallis)" <frank.hinde@hp.com> 12/16/2005 Hello Frank, You raise a good point. You wrote <<......skip.....In any case, I thought the 2 year VFR cert was a transponder only test...And IFR was the encoder/pitot/static test??....skip......>> I think that whether or not the VFR cert gets involved with the altitude encoder or not depends upon the interpretation of FAR Sec. 91.413 (b) which reads: "Following any installation or maintenance on an ATC transponder where data correspondence error could be introduced, the integrated system has been tested, inspected, and found to comply with paragraph (c), appendix E, of part 43 of this chapter." And the title of paragraph (c), appendix E, of part 43 reads: "(c) Automatic Pressure Altitude Reporting Equipment and ATC Transponder System Integration Test." I have never had just a VFR certification alone performed on an airplane by a shop so I don't know how they interpret 91.413 (b). Can anyone enlighten me? Thanks. OC <<Hi OC, As far as removal goes it's a piece of cake...simply a screw on the front...As long as the thing has power/ground and a pressure it will show altitude. If I was faced with having to remove the EFIS I would probably make up a D sub with the apprpriate wires to save the shop any (expensive) confusion...:) In any case, I thought the 2 year VFR cert was a transponder only test...And IFR was the encoder/pitot/static test?? Frank>>

    --> Avionics-List message posted by: Werner Schneider <glastar@gmx.net> Hello OC, I'm not eligible to answer that in full, in Europe we have an AD which you have to comply with. It is aimed at the gray code encoders as you have there many wires you have to test the transponder for correct output any second year. serial encoder/transponder combination are not impacted as there you see immediately ok/nok, where the gray code would send wrong altitudes. br Werner bakerocb@cox.net wrote: >--> Avionics-List message posted by: <bakerocb@cox.net> > >Responding to an AeroElectric-List message previously posted by: "Hinde, >Frank George (Corvallis)" <frank.hinde@hp.com> > >12/16/2005 > >Hello Frank, You raise a good point. > >You wrote <<......skip.....In any case, I thought the 2 year VFR cert was a >transponder only >test...And IFR was the encoder/pitot/static test??....skip......>> > >I think that whether or not the VFR cert gets involved with the altitude >encoder or not depends upon the interpretation of FAR Sec. 91.413 (b) which >reads: "Following any installation or maintenance on an ATC transponder >where data correspondence error could be introduced, the integrated system >has been tested, inspected, and found to comply with paragraph (c), appendix >E, of part 43 of this chapter." > >And the title of paragraph (c), appendix E, of part 43 reads: "(c) Automatic >Pressure Altitude Reporting Equipment and ATC Transponder System Integration >Test." > >I have never had just a VFR certification alone performed on an airplane by >a shop so I don't know how they interpret 91.413 (b).

    --> Avionics-List message posted by: NYTerminat@aol.com Listers I have a quick question on the certification of the transponder/ encoder. Does this have to be done before you can get a DAR or FAA sign off on your experimental? Does the original certification of the new equipment count initially? If not how does one get the plane to an airport that have an avionics shop without first flying? Thanks Bob Spudis CH-701/912s first start tomorrow
