Pietenpol-List: electrical system

Howdy, low 'n' slow fliers;There are various regulatory references to aircraft withandwithout electrical systems. Does anyone know if the regsdefine what constitutes an electrical system? I may haveasked this question in the past but my memory isn'twhatI think it used to be (but I don't remember that,either).If a battery is used to power radios or anything else butthereis no alternator or generator fitted to the aircraft enginetopower the bus or recharge the battery, does thatconstitute an electrical system?Thanks.Oscar ZunigaAir Camper NX41CCSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.nethttp://www.matr &n - &nbs -->http://www.matronics.com/co================ Email Forum -Navigator to browseList Un/Subscription,7-Day Browse, Chat, FAQ,http://www.matronics.com/Navigator?Piet ... ______Date: Thu, 19 Mar 2009 12:10:16 -0400 (EDT)

I think the short answer is yes. You have a source of electrical power anda distribution system. There are electrical cables, hopefully fuses orcircuit breakers and a load (radio) all installed on the aircraft.Bob -----Original Message-----

I'd recommend we consult the regs.My memory says that the hangup with an FAA defined electrical system is that you must have a transponder. I remember thinking that you could have a battery and a starter, but so long as there was no alternator or generator, there was no "electrical system".

In my dealings with the Feds, they define an electrical system as "engine driven." If you have a gell cell powering a transponder and radio, with no way to charge it in flight, then you do not have a true electrical system per the regs.

See Jeff Boatright's paragraph below my signature. Jeff is correct. That "may" constitute an electrical system depending on interpretation. Here is some text from AIM. Oscar, I have been assuming this is a transponder issue but i may be all wet. Would not be the first time. From the AIM (4-1-19):2. In general, the CFR's require aircraft to be equipped with Mode C transponders when operating:(a) At or above 10,000 feet MSL over the 48 contiguous states or the District of Columbia, excluding that airspace below 2,500 feet AGL;(b) Within 30 miles of a Class B airspace primary airport, below 10,000 feet MSL. Balloons, gliders, and aircraft not equipped with an engine driven electrical system are excepted from the above requirements when operating below the floor of Class A airspace and/ or; outside of a Class B airspace and below the ceiling of the Class B airspace (or 10,000 feet MSL, whichever is lower);(c) Within and above all Class C airspace, up to 10,000 feet MSL;(d) Within 10 miles of certain designated airports, excluding that airspace which is both outside the Class D surface area and below 1,200 feet AGL. Balloons, gliders and aircraft not equipped with an engine driven electrical system are excepted from this requirement.John HofmannVice-President, Information TechnologyThe Rees Group, Inc.2810 Crossroads Drive, Ste 3800Madison, WI 53718Phone: 608.443.2468 ext 150Fax: 608.443.2474Email: jhofmann(at)reesgroupinc.comOn Mar 19, 2009, at 10:03 AM, Jeff Boatright wrote:> Might be different at various FSDOs, but as per a/c inspected in the > Atlanta area that I know of, an electrical system must have a > recharging component (e.g., alternator, generator).

John is correct. If you have an engine driven method of re-charging inflight, then you have an electrical system and are required to have a Mode Ctransponder. However, this is offset by being able to have lights and flyat night, which you cannot legally do unless you have a means of rechargingin flight.My Pietenpol has a ground charge only electrical system (some of you mayhave seen it at Brodhead last year, with a long power cord running to thehangar where they serve breakfast as I recharged my battery). I use it topower the radio, the intercom and the transponder, and most important - theAh-Ooooga horn. Having the transponder is useful at times. Without it, Iwould not have been able to fly it into Dulles International Airport lastJune to put it on display at the Smithsonian's Udvar-Hazy Museum.Jack PhillipsNX899JP _____

I didn't see that option in the briefing on flying into the Washington ADIZ.They barely tolerate VFR traffic and I think it would be an enormous battleto get in without a Transponder.-----Original Message-----

well, Jack could have flown into Dulles without a transponder, I have done it several times no radio and no transponder, it just has to be coordinated. I am a little surprised that Jack has a transponder on a battery only -- how long do you get out of it?? I have never tried, but always thought a transponder drained a battery pretty quickly, too quickly to be useful, but apparently not.Like everyone has said, if it was certified with an engine-driven electrical system, or if it was ever modified to have an engine-driven electrical system (you can't remove it), you have to have a transponder. Other than that, you are free. I have been fussed at by towers in class C airspace for having a radio and no transponder, but I proved them wrong every time (I kept the regulation cite handy and quoted it to them)Genebuilding wing like crazy ----- Original Message -----

I'm not so sure about your statement that you must have charging to fly at night, a number of aircraft are certified and legal to fly at night on batteries only.Gene ----- Original Message -----

Gene, you are right that the transponder drains the battery pretty quickly.I've got an 18 Amp-Hour battery and it will run the comm radio and GPS forseveral days, or the transponder for a few hours. I typically only turn thetransponder on when going into Class C or Class B airspace, and turn it offas soon as I'm clear of them. Yes, you can enter such airspace without it,but it take so much telephone coordination and casuses so much confusion I'drather just use the transponder. Besides, it's fun to call up approachcontrol and just call yourself an experimental, then throttle it back toabout 45 mph indicated and ask them for a groundspeed check.Jack PhillipsNX899JP _____

FAR 91.215 says: ... 3) Notwithstanding paragraph (b)(2) of this section,any aircraft which was not originally certificated with an engine-drivenelectrical system or which has not subsequently been certified with such asystem installed, balloon or glider may conduct operations in the airspacewithin 30 nautical miles of an airport listed in appendix D, section 1 ofthis part provided such operations are conducted-(i) Outside any Class A, Class B, or Class C airspace area; and(ii) Below the altitude of the ceiling of a Class B or Class C airspace areadesignated for an airport or 10,000 feet MSL, whichever is lower; and...So that covers the transponder installation. If you have an engine drivensystem, you have to have a transponder (and use it).As for lights for night-flying, FAR 91.205 says: ... c) Visual flight rules(night). For VFR flight at night, the following instruments and equipmentare required:(1) Instruments and equipment specified in paragraph (b) of this section.(2) Approved position lights.(3) An approved aviation red or aviation white anticollision light system onall U.S.-registered civil aircraft. Anticollision light systems initiallyinstalled after August 11, 1971, on aircraft for which a type certificatewas issued or applied for before August 11, 1971, must at least meet theanticollision light standards of part 23, 25, 27, or 29 of this chapter, asapplicable, that were in effect on August 10, 1971, except that the colormay be either aviation red or aviation white. In the event of failure of anylight of the anticollision light system, operations with the aircraft may becontinued to a stop where repairs or replacement can be made.(4) If the aircraft is operated for hire, one electric landing light.(5) An adequate source of electrical energy for all installed electrical andradio equipment.(6) One spare set of fuses, or three spare fuses of each kind required, thatare accessible to the pilot in flight.To me, that does not sound like a generator since a battery can be a sourceof electrical energy. Before trying it with just a battery though, I'd askyour local FSDO.Jack PhillipsNX899JP-----Original Message-----
