EAA - The Spirit of Aviation
Vol. 5, No. 8 November 2012

I promised a bit more on my accident last month. I'd like to focus on two simple ideas: how it happened and how I could have avoided it. Both should present valuable opportunities for learning, especially but not limited to builders of RV-xA series of amateur-built aircraft. But first, I'd like to thank Keith Walker for pointing me toward this interview with John King (yes, of John and Martha fame). Read more Ian Brown

It's that time of year again to start thinking about preparing for winter and cold weather operations. Over the years, we have become more educated about the importance of properly preheating an aircraft engine prior to attempting a cold start. The need to preheat goes beyond just the ability to start the cold engine; it is known that proper engine preheat enables safer winter operations, helps save on fuel costs with shorter run-up times, and avoids unnecessary engine wear. The folks at Tanis Aircraft Products, Eden Prairie, Minnesota, provided us with the following information. Read more Cold Weather Operations

I now have several hours of flight time logged on my new homebuilt. I am becoming quite comfortable with basic flight maneuvers and also have several hours working the engine to help break in seating of the rings. It's time to proceed with the exploration of the flight envelope.

In Canada, we normally would need to fly off a total of 25 hours of trouble-free flight under a flight authority before receiving our special certificate of airworthiness for our amateur-built aeroplane. During this test period, we want to explore the flight envelope. And so we will look at the various simple flight tests we can do, the data we can collect, and the reduction of this data to useful information contained in our own pilot's operating handbook (POH).

Test Flight Card

Upon its introduction, the Dynon D10A was really state of the art, and with its 20 integrated functions it could replace a lot of the standard panel instruments. At the time it seemed like there was not a lot more you could want. Today, however, the Skyview series has an amazing assortment of extra capabilities. If you really want to dig deep into the latest capabilities, you can go directly to the Dynon website. The following information is drawn from that site. Here are a few examples of how the product has advanced. Read more Electronics Corner
Classic squeezed-rivet removal calls for a hole to be drilled in the head and a pin punch used to snap off the manufactured head. A simple pin punch can cost $8 or more, and a good one might be hard to find. Or perhaps you'll have to wait for a replacement to be delivered. You probably already have a ready stock of the high-grade steel of the precise diameter you need to make your own design, without realizing it. A broken drill bit of the required size and your favourite file or die handle will do the trick.

This one needed some extra stabilization inside the handle, along with grinding off square at the end to get a nice clean fit as well as a bit of a biting edge inside a newly drilled hole in the rivet head, but it works just fine.

Please share your own tip with your fellow readers via e-mail to the editor.

Word of the Month: Overshoot
Apparently one aviation word that separates our two languages - not English and French; this difference is between Canadian and American English - is "overshoot". You might never know of this difference unless you have to clarify to an American that what you meant was a "go-around". For an American pilot an "overshoot" is a reason to "go around" because he overshot his target. It's also used more generally to indicate having overrun something like a target point or a runway. In fact the press seems to use it most often for aircraft running off the runway. Read more

Aviation Words
Fifty years ago in an interesting article by Pete Bowers, designer of the Fly Baby, he suggested we should "lose no time" in changing the name of the Experimental Aircraft Association to the Sport Aviation Association. He made a couple of valid points. First, he said that the word "experimental" had negative connotations when dealing with people and organizations outside our own. He also suggested that since our monthly magazine name had recently been changed from Experimenter to Sport Aviation, the name change would make sense and that the new acronym would only change in one letter.
