I am, indeed, prejudiced by my income from petroleum, but I am also reasonably well informed by my years following that industry. I don't feel threatened by alcohol, but I do believe it is a poor choice for airplane fuel. You did a good job of covering the problems of carburetor and other fuel system damage from alcohol. I don't know how to make these elements alcohol proof, but I would like to. If you have any specific information on gaskets, fuel lines, and other materials that resist the alcohol I would love to hear it. It does take a considerable amount of energy to produce alcohol. I don't know about the statement that it takes more petroleum fuel than the alcohol produced, but your point about costs for alcohol is a good one. I think the energy needed to process the farmer's fields and harvest and transport the corn must be combined with the energy needed to boil the fermented mash to separate the alcohol from the other materials. If all of this energy came from petroleum then it might indeed take more than a gallon of petro-fuel to produce a gallon of alcohol, but there are many other energy sources that could be used for the distillation process. I am concerned about your comment regarding draining water from the fuel regularly. The alcohol actually dissolves water in the liquid, so draining it only gets some of the water out of the fuel. I think there will still be a considerable amount of water going through the engine even if there is no apparent water in the fuel tanks. The part that pilots really need to know is that alcohol has considerably less energy per gallon than gasoline. (Also, gasoline has a similar reduction in energy per gallon compared to diesel fuel.) That means the range of your plane will be reduced if you use alcohol. I don't care much about the cost implications of this reduction, but it could be a serious safety issue if you fly with minimum fuel margins and don't factor in the need for additional gallons of fuel when it contains alcohol. I'm not sure, but I suspect the variable amount of water in alcohol based fuels could also make a considerable reduction in airplane range. I am troubled by the government forcing alcohol into virtually all gasoline. At the same time the federal government also imposes a large import duty on alcohol. I think this is a misguided attempt to create energy independence for the USA. It also means converting large food production capacities to fuel production which might help with the fuel situation but lead to starvation for lower income people.

This, in fact is how you test for alcohol in gasoline. Gasohol is actually a relatively low octane gasoline with alcohol added. The alcohol increases the octane of the mixture to its rated value. Now you have a mixture of alcohol and water at the bottom of the tank that probably won't burn too well and gasoline floating on top with a significantly reduced octane rating. Now when you sump the tank, you'll be draining out most of the alcohol along with the water, leaving behind the low octane gasoline. For an automobile, this isn't much of a problem since autos produced today generally have knock sensors and computer controlled ignition systems that can compensate for the lower octane fuel. Most aircraft engines don't have this ability and burning a lower octane fuel than the engine requires can rapidly destroy the engine. If the fuel system and engine is designed for it, burning straight alcohol or E85 should not be a problem. This fuel should be relatively insensitive to a small amount of water in the mix. Mixing small amounts of alcohol with gasoline is a bad idea. Alcohol is a pretty good motor fuel by itself if the engine is designed to run on it. Gasoline is also a good motor fuel. Mixing alcohol with gasoline produces a fuel with more problems than advantages. We need to get the politicians out of the loop and leave fuel system and engine design to people who actually know what they're doing. > > Hi Don, > > ... > > I am concerned about your comment regarding draining water from the > fuel regularly.

This unit measures airspeed and vertical acceleration and talks to the pilot through the headset. No dials or lights to look at so you can keep your eyes out of the window all the way down the approach. One mode of operation for this unit is as a "stall margin preserver" that tells the pilot (through their headset) if they are diverging from a chosen approach speed. If they pull G, that gets noticed instantly so it's a bit like having an AOA instrument compared to just using an ASI alone. The reason I invented it was because I wanted to keep my eyes out of the cockpit while still flying a very accurate approach. Details can be found at www.smartavionics.com Cheers, Mark PS - I agree that being able to fly your aircraft by feel alone and not looking at the instruments is a great skill to have, but if you are as dozy a pilot as I am, you need all the help you can get!

BRS's recommendations regarding installation in a 701 probably won't work! They recommend attaching two heavy "L"s to the inside back of the unreinforced baggage compartment. These "L"s are strong, but not what they are attached to. I understand that when the chute ignites, there is considerable downward force, which would most certainly distort the baggage compartment, which could prevent the chute from deploying properly. I added reinforcement from which my 180# bod was able to hang from without distortion. My installation is behind the baggage compartment. This frees up baggage space, but makes the plane's CG a little further aft than I would like (but still within limits) Another advantage of a behind baggage compartment installation is protection from the shell.
