Electric Flight
Here's what some readers have said

Paul PobereznyLast month I wrote my editorial moments before leaving for the 2010 CAFE Electric Aircraft Symposium. I left with a "skull full of mush" hoping to come home with enough education to begin seeking out, editing, filtering (the wheat from the chaff), and potentially writing electric flight articles in an intelligent manner. Although I wish that each presenter at the symposium could have talked several times longer than they did, I believe my educational goal was met. As such, I would like to sincerely thank all the CAFE volunteers that worked hard to bring us the symposium, and I would like to offer my gratitude to each of the presenters who were willing to freely share their research and developments. I won't be going into any details in this issue however the editorial I wrote last month caused an avalanche of letters to the editor like never before. You can take a look at just a few of them by clicking: Read more

In every issue of Experimenter, a link to a survey is provided. The responses you make are anonymous, unless you elect to leave your contact info. I read each and every response and take your comments seriously while doing my best to fulfill requests and to apply criticism appropriately. I urge you to participate in this process, especially if you have never done so before. The entire Experimenter staff wants to hear from you so that we can continue to provide the content we know you want. The link can normally be found in the right-hand column, but you can also take the survey by clicking here.

Paul's Pick
Paul PobereznyPaul wrote in Sport Aviation in December, 1972 that the FAA was committed to safety and the freedom to build and fly. He also felt that the EAA community had to be prepared with an organized answer when tragedy skewed the public's perception of recreational flying.

"I am convinced that FAA desires to insure the future of the amateur-built movement and the privileges we enjoy in building and flying-in such a way that they are not lost because of spectacular mishaps, pressures from citizens groups, or Congress. On the other hand, what do we have to offer in the way of standards in the event we are called upon to answer for our actions?" Read Paul's column

Tales From the DAR Side
Joe NorrisAttack of the Placards

Last month, I discussed the "EXPERIMENTAL" marking and passenger warning placard. Beyond those items there's a general requirement for placards and markings called out in 14 CFR 91.9. While there's no specific guidance for these markings, the idea is to make it obvious what each switch, control, fuse, or circuit breaker does. Plus, a follow-up to some of your questions about N numbers.

Jake Jaks' Pober Junior Ace
15 years of work
Pober Junior AceIt's always an honor to complete an experimental aircraft and have the designer look it over and give it the thumbs-up. Such was the case with Jacob Jaks and his Pober Junior Ace when he had the opportunity to show it to EAA Founder Paul Poberezny at the 2009 Sun 'n Fun Fly-In at Lakeland, Florida. That meeting is only a small part of this story of building the plane from scratch, deviating from the plans just enough to successfully install a Corvair engine. Read more

Fournier RF4D, Part 2
Flight Evaluation

Fournier In the April issue of Experimenter we reintroduced the Fournier RF4D self-launch sailplane, a very capable cross-country machine certified in France, many of which being lovingly restored and maintained in the United States under the experimental-exhibition rules. Its wood and fabric construction makes it an easy restoration for anyone with the confidence to take on such a project that once finished, can be flown by pilots who hold a glider category rating and a self-launch endorsement. Since no medical certificate or drivers license is required for glider operations, there is no restriction on pilots whose most recent FAA medical certificate was denied, suspended, revoked or withdrawn by the FAA.

This month we follow up with an article on the piloting aspect of owning and operating a Fournier RF4D. Read more

Electric Aircraft Advances Showcased at CAFE Symposium
In last month’s editorial, Experimenter editor Patrick Panzera made reference to his (then) upcoming attendance at the 2010 CAFE Foundation Electric Aircraft Symposium in order to get an overall grasp on the advances of electric flight and its immediate viability. EAA reporter Peter S. Lert also attended the symposium and gives his opinion on the overall event. Read more

The Electric-Powered Aircraft
Technical challenges
Electric aircraft
The thought of buzzing around the sky, quietly, with no carbon emissions is an enchanting one - and the promise of electrically powered airplanes. Just plug it in for a couple of hours and go flying. No carb ice, no oil stains, no $5 per gallon avgas. But how close is this to becoming a reality? How developed are the technologies that are needed to make an electrically powered aircraft? David Ullman takes a look at the different types of components, their state-of-the-art technology, and what developments you can expect. Read more

Don't Miss Canadian Pilot License Deadline
Pilot's LicenseTime is running out for Canadian pilots to apply for a new license from Transport Canada. The new style of license incorporates several requirements mandated by the International Civil Aviation Organization regarding security and fraud. Pilots who submit their application before the June 30 deadline will be issued a temporary certificate while their application is being processed. Currently there is a backlog and those who wait until after the deadline to apply miss out on the temporary certificate option and their license will be invalid until their new one arrives. An application can be found here.

From the Archives
Sport Aviation, May 1982
Rag Rose

In this month's issue, we present the story of Jake Jaks' Pober Junior Ace, which he built from plans. In November 1979, Sharron and Ted Travis began building "Rag Rose," a Corben Junior Ace they finished and debuted at EAA Oshkosh 1980. Unfortunately they had to ditch it in the woods on the way home to Michigan due to a carburetor problem. The Travises preferred to build from scratch or not at all, so rebuilding the aircraft in less than a year was quite a feat. It wowed the judges when it returned to Oshkosh in 1981. Read the article

You can also search the archives by subject for a multitude of technical and how-to articles.

Aviation Glossary
Confused by a strange aeronautical term? EAA's online Aviation Glossary can help.

INDUCTANCE - (1) The property of an electric circuit by which a varying current in it produces a varying magnetic field that induces voltages in the same circuit or in a nearby circuit. It is measured in henrys. Inductance symbol: L. (2) The capacity of an electric circuit for producing a counter electromotive force when the current changes.

NITRIDING - Gas nitriding is a case-hardening process whereby nitrogen is introduced into the surface of a solid ferrous alloy by holding the metal at a suitable temperature and in contact with a nitrogenous gas, usually ammonia. Nitrogen released by the decomposition of ammonia reacts with the metal to make iron nitride, a hardening substance. Process methods for nitriding include: gas (box furnace or fluidized bed), liquid (salt bath), and plasma (ion) nitriding.

Forum Review
The Eyes of an Engineer: Burt Rutan on Climate Change at AirVenture 2009
It's hard to mention electric flight or even electric automobiles without relating this technology to a reduced negative impact to the environment compared to its gasoline-powered counterpart. There's no doubt that reducing combustion emissions is good for everyone. At EAA AirVenture Oshkosh 2009, Burt Rutan looked at the climate change issues from an impartial engineer's perspective in an informative presentation. No matter where you might stand on the issues, this presentation will be eye opening and worth hearing. Listen to the forum.

UV-resistant packing tape for wing covering? 

If you're building an RV or not, "Construction Materials, Processes and Useful Information" by Van's Aircraft is a treasure trove of information for anyone building a metal plane.

David Algie of Algie Composite Aircraft is the innovator behind this unique aircraft project you may have seen at the Sun 'n Fun Fly-In at Lakeland, Florida, last month. All composite and designed around the use of a small block Chevrolet engine, the LP1 promises to be quite the performer.

Rod Herzig likes to fly and film with his Cozy III. Using a GroPro Motorsports Hero camera he filmed over a two week period earlier this year while flying around western Massachusetts and Southern New Hampshire. It comes with many different attachments and a 170 degree lens which allowed him to get some incredible shots.
