Ski Plane Flying in Alaska




In Alaska, the percentage of residents with planes is higher than anywhere else in the U.S.
An Alaskan Commute
This makes sense, since distances are vast, the terrain so varied, and the entire, huge state has only 3 highways – well – we call them highways (four or more lane roads). It is often faster AND cheaper in gas to fly between two points than to drive a circuitous route around a mountain or body of water. Since my husband and I live off-road, we too, have a plane, a 1954 red and white Piper PA-20, that lands on our lake, on floats, in summer, and on skis, in winter. I've written elsewhere about summer time “Float Plane Follies” so here, I will describe a typical trip with our ski plane, starting with the pre-flight checks, the flying, and then the landing.

Pre-Flight:
In winter, as anyone without a heated car garage can imagine, we need to pre-heat the plane. Part of the engine is constructed of steel, and part of aluminum (to save weight). Since these two metals expand and contract at different rates in extreme temperatures, we need to warm the engine so that the metals are closer to the temperature ranges they were designed for. My husband generally parks his snowmachine next to the plane on the (frozen) lake, carrying a 20 lb propane tank and a Red Dragon torch. The vehicle's battery provides power and the propane the fuel to heat the torch, which looks like a something in a household HVAC system, with a metal, corrugated tube (blower), about 2 feet long and 5 inches wide. He sticks the blower tube up into the engine, inserts the plane engine's exhaust manifold (pipe) into it, and thus heats both the engine compartment and the internal piping. This takes about an hour. Meanwhile, he goes through a 42 point safety checklist.

When we are ready to leave, we remove the cowl cover (from the nose cone), which looks

like a giant, padded bra for one boob, and the (fabric) wing covers (red tags for the port side, and green tags for starboard because those are the colors of the respective navigation lights). These covers protect the plane from accumulating ice weight in two ways. Since they are black, they tend to heat up and melt any accumulated snow when sunny, and since they have padded baffles that stick up along the front edge, they shake and shiver in the wind, deterring ice formation. For short trips, we generally take the cowl cover with us (it will keep the engine warm for several hours) but we stow the bulky wing covers in a little plastic sled under the cabin, out of the wind.

Do You Know Your Water Source, Use, Cost?


How much do you know about your own water supply and usage? Where does it come from? Where does it go? How much does it cost? Which inventors, engineers, and companies can you thank for these resources?

Many people are surprised to realize how little they know about resources they rely on so completely. I certainly took water for granted when I lived in a city with a municipal water supply. How will you do on the following quiz? 

Of the people I asked before writing this, many knew the source of their water, but NONE knew offhand, water consumption, unit costs, personal usage or post-use processing.  And yet, we all know how important water is. 

Once you take your quiz, you may be interested in my comparative source and usage rates at our little log cabin, off grid in Alaska, where I have become hyper- aware of how much we produce, how much it costs, and how much we can use before having to go without!

HOME WATER QUIZ:
a) What is the source of your water (for example, a lake, aquifer, river, glacier, rain, or well)?
b) Is that source stable or declining?
c) Where do the grey water (sink and tub) and sewage go?
d) How much power does it take to deliver your water to you (for example a truck delivery of bottled water, a pump for a well or the infrastructure of the municipal water system)? What is the source of that power?
e) If you use municipal water, how old is that complex? How does its water quality compare to other cities? (Call to see if they offer tours to individuals or groups. A city water plant is a fascinating and important place. Because of them, many cities conquered the water borne diseases that still bedevil many parts of the world. Find out how much your city's plant costs to build and maintain)
f) How much do you pay for your water supply?
g) How much water do you use?
h) For what? (some water monitors segregate statistics for outdoor and indoor use, or for potable or non-potable water. Some high-rises have water cooled air conditioning systems).
I) Do you know how much water is used in your average bath, shower, dishwasher, clothes wash cycle, toilet flush, lawn, swimming pool etc? (This is easy to look up on line) How much do you use for cooking and drinking, or for your pets?

HOW DID YOU DO?
