Fine example of Tarver Engineering release for service
A fine example of the quality results of Tarver Engineering work. As
singed off by John Tarver with applicable 8130. http://www.aart-jan.net/images/aart_...egtuigwrak.jpg photograph courtesy of Aart-Jan, (its not tarver in the pic, it's Aart's father inspecting the fine work completed by John "the splap" Tarver). |

Was that before or after the first flight? ;-)

Ummm,
I performed dozens of the old FAR 91.171 (pitot/static annual checks) and 91.172 (mode 'C' checks) in the early 90's on Pipers, Cessna, Grumman, Lanceair, Beech, you name it. Also performed all the calibration and repair necessary, (the lines, indicators, ports, pitot tubes, etc.) I worked a part time job at a GA avionics shop at Palo Alto. IIRC, the only indicator that had both pitot and static inputs was the VSI/Rate of climb indicator and the internal bellows in the gauge performed the differential action. Airspeed has pitot inputs only. Baro Alt. has static port input only. Wish I could draw you a diagram on here, it would explain everything.

Since posting rubbish like he posted below, no amount of diagrams have helped. It's a case of "That's my story and I'm sticking to it!" Revealing that in my 37 years up the road at SFO I had done easily hundreds of low range pitot/static leak tests resulting in the replacement of dozens of pitot tubes/probes/masts or whatever Tarver wants to call those pointy things up front, only brought about months of fraud claims and all of the other bits splaps is well known for. Requoting Gord's question to me out of context is only his latest. Pt *still* equals (altitude pressure) + (impact pressure). JK http://home.att.net/~j.knoyle/the_ta...hronicles.html GREAT MOMENTS IN ADA: "That is the case with all modern transports Gord. Pitot tubes are only used for flight test back up instrumentation for modern transports; pitot tubes have a nasty habbit of atracting mud bees and are therefore not reliable enough for revenue these past few decades." -- John Tarver, Skylight Avionics, December 26, 2001 |

I know...ain't life a bitch John snipping posts to claim that other people posted waht someone else entirely posted. pathetic, childish, immature, and the sure sign of your desparte need to obfuscate your stupidity |

Airspeed has pitot inputs only. Baro Alt. has static port input only. Wish I could draw you a diagram on here, it would explain everything. Ummmm.....I think that you definately DO NOT recall correctly! Static Pressure feeds Altimeter, Airspeed, and VSI. Pitot Pressure feeds only Airspeed. The Pitot Pressure from the Pitot Tube is a combination of Static and RAM pressure. The bellows inside the airspeed indicator uses the ambient static pressure from the static port to cancel out the static component from the Pitot Tube leaving only the RAM component to move the airspeed needle.
