"Tarver Engineering" wrote in message news "Matthew S. Whiting" wrote in message ... No, you have trouble writing things that make sense. What is unreliable about a pitot tube? The heater is likely the least reliable part. Which airplane(s) have pitot ports? I don't think I've seen one. What makes them more reliable? I have no interest in educating you, Whiting. A typical Tarver response when querried for "Hard Data". Ralph Nesbitt Professional FD/CFR/ARFF Type |

Yes, I'm just a nice guy. :-) You do have that going for you so far. Your ignorance of pitot static systems is typical, however. Yes, it seems to match yours, so I guess two of us makes it qualify as typical. :-) I thought you were disagreeing with me based on ignorance. A prime example of the results of trying to do something you are not qualified to do, "Like Thinking", IMHO. Ralph Nesbitt Professional FD/CFR/ARFF Type |

Phil -- Is "Prop Wash" an acceptable substitute for "Jet Wash" in this situation, or is it necessary to use "Jet Wash" on Jet A/C 'Pitot Tubes", "Prop Wash" on "Pitot Tubes" on A/C using "Propellers", & "Rotor Wash" on Pitot Tubes on Helo's?

"fudog50" wrote in message ... snip 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. Ok, what they taught me was that the VSI ran on static pressure and *metered* static pressure. I'm not aware that pitot pressure (which is directly related to airspeed) would be of use for a VSI. Can you explain how that would be used in a VSI? I can't see any connection. The only time pitot pressure = static pressure is if the aircraft is stationary and there is no wind. The difference between static port pressure and static pressure that was restricted as to the rate it could alter (inside the VSI) by way of a port that is very small in comparision to the main static port gives the rate that pressure (and therefore altitude) is changing, giving you a rate of climb or descent. Airspeed has pitot inputs only. ISTR that an ASI that can give you a TAS instead of an IAS had static pressure and temp sensors in addition to the pitot inputs, *or* it was in some way coupled to the altimeter, so that it could show a corrected TAS based on density altitude, but I've never actually had one in my hand. IIRC, a PA28-180R I used to fly out of Broken Hill many years ago had a TAS meter fitted, but I wasn't aware of exactly how it worked at the time. Baro Alt. has static port input only. Yup. An altimeter is basically an aneroid barometer. Wish I could draw you a diagram on here, it would explain everything. It always helps. The CO |

We all know the fudog's memory failed him this time. One thing -- The pitot pressure isn't "directly related to airspeed", (and we know you meant IAS, not TAS).

Well, I thought the bit about a VSI using pitot was a bit, um, well, wrong. One thing -- The pitot pressure isn't "directly related to airspeed", (and we know you meant IAS, not TAS). One, sorry didn't mean 'directly' in the physics/math sense, only that it was the input for an ASI (compared to static pressure of course) An airspeed indicator gives you Indicated Air Speed. Q.E.D. (A TAS indicator can also give you a TAS readout as it can apply a correction for the density altitude, but IAS is what you base your flying on (as opposed to nav).
