But since there are things that could hurt cruise speed without affecting the stall, it just makes no sense to rely on stalling behavior to "know" the cruise speed (even if you could actually determine the actual cruise speed by stalling the airplane, which you can't). If you care about cruise speed, you need to actually measure cruise speed. As Julian already said, doing so is the reliable way to determine cruise speed. Pete |

As Julian already said, doing so is the reliable way to determine cruise speed. I have a stupid n00b question to add to this thread. Mooney #1 was tested on a cool, dry day in Colorado at a density altitude of 8500' using the GPS square course method. Mooney #2 was tested on a hot, humid day in Texas at a density altitude of 8500' using the same method and power settings. Can the results of these two tests be used to accurately compare speed down to a single knot? I'm guessing the answer is "yes". Whatever the answer, though, it seems that measuring cruise speed would still be the best way to measure cruise speed. |

If you care about cruise speed, you need to actually measure cruise speed. As Julian already said, doing so is the reliable way to determine cruise speed. I think you are envisioning a situation where you are presented with 6 Mooneys on the ramp with your choice to buy. Of course in that situation you can fly each and compare the price. But if you are traveling 100 miles out to test fly a Mooney before buying it, I just don't see how you are going to determine if it is well rigged and fast just on its own. Unless you have several Mooneys ready to fly to compare you just can't use a 4 course speed test. Stalling it will give you a good idea of its rigged right (90% of the speed differences between Mooneys). From my experiences buying airplanes for personal use I can say that you spend a lot of tired hours flying around the country looking at planes that you are told are great only to find them a piece of crap. Once you do find one that is good, you want to start spending money on it (inspection, offers, etc). If you want to travel around teh country test flying a dozen or so planes you'll end up putting in a lot of time off work as well as a lot of money moving around. I've considered buying a little Aeronca to knock around in as a second airplane. I've already spent almost as much as the Vref of an Aeronca traveling around for an Aeronca and have not yet found one that is both airworthy and priced less than 150% of Vref. You can burn through cash very, very, very fast just searching and inspecting planes. -Robert |
