Having a copy of such a letter in the cockpit, would allow flyovers and missing man flights held in conjunction with local events. Certain guidelines would apply of course, minimum altitudes, ATC clearances when in controlled airspace, etc. Craig Payne ________________________________ Message 2 _____________________________________ Time: 04:45:30 AM PST US From: "Daniel Fortin" Subject: RE: Yak-List: Wavier --> Yak-List message posted by: "Daniel Fortin" Just call it "exebition". It is after all the basis of certification for your airplanes.

Chromel (NiCr, also known as Nichrome) is a fairly common material used in thermocouples and is used in type 'K'. The other material is Alumel (NiAl). Nickel is magnetic. Type 'J' is iron/constantan (CuNi -- copper and nickel). I would expect both of these materials to be magnetic. 'N' is nitrogen, 'B' is Boron, and 'Mn' is Manganese. I have never heard of those being used in a thermocouple. Boron is getting pretty close on the periodic chart to being a semiconductor and it is pretty hard to nail Nitrogen down to anything that isn't ultimately an explosive (or at least highly reactive). But it could be just an error in translating from the Chinese to English. But it sounds as if you are looking for the extension leads and that is another story. If you get the wrong leads the calibration will be off. Regardless, the material in the leads does not have to be the same as the material in the thermocouple. The materials in the leads are selected to provide cold-junction compensation and thus allow you to use regular copper wires after the compensating lead to the instrument itself. Why don't you get a new lead from Doug and not have to worry about calibration? And my information is worth every penny you paid for it. -- Brian Lloyd 6501 Red Hook Plaza brianl@lloyd.com Suite 201 http://www.lloyd.com St. Thomas, VI 00802 +1.340.998.9447 (voice) +1.360.838.9669 (fax) There is a time to laud one's country and a time to protest.

Does anyone have any info? If there is no instructor in waiting, we may be able to recruit Sergei Boriak again this year -- if there is interest in having him back. The arrangement would be the same: all who participate in the training from this aerobatic champion and US Aerobatic Team Coach would pay Sergei his hourly fee and pitch in with the other participants to share his expenses. Those who have done so in years past have said the money is well spent. Please let me know "off list" if you are interested. Regards, Mike Filucci _mfilucci@aol.com_ (mailto:mfilucci@aol.com)
