Aviation Related Presentations
I have created several presentations on soaring and aviation related topics such as flight computers, recorders, ELTs and PLBs, avionics wiring, trailers, blipmaps and more. See this web page for more details.
Pilot Relief Systems
I have brought together information on my experiences with pilot relief ("pee") systems for glider and soaring pilots along with information from other resources. See this web page for more details.
Testing Batteries - Manual and Automated
Each year I like to test my ship's batteries and replace those that do not have enough individual capacity to last 3 hours at a 1A load. But how can the average pilot perform a reasonable "real world" test with easily obtainable equipment?
See the Excel spreadsheets linked below and this Soaring magazine article for an explanation of the testing that I perform and the simple test rig that I use, along with Excel templates for gathering the data and then graphing the results.
There are three versions of the spreadsheet;
2 Line LCD Display     240x320 LCD Display

Manually taking hours of battery test readings can be BORING! I have now automated testing using an inexpensive Arduino Duemilanove single board computer coupled with an LCD display (shield) and a few other components. There are two versions of the display. Initially I used a simple 2 line by 16 character LCD B/W display. Now I am using a 240x320 pixel LCD touch sensitive color display which allows more room for information, a simple graph, and other niceties. The complete required Arduino hardware might cost you $20-$30 on eBay.
The Arduino free editing software (required) is available here. After you open my Arduino code packages you will find full instructions in the comments near the top.
Pictures and my latest Arduino software package can be found here. An Excel spreadsheet to parse your automated data, and to graph the results, is also available in the same folder.
Soaring Landout Survival Kit
Over the years I have created a survival kit which I carry in my glider at all times to be prepared for landouts. See this web page for more details.
IGC File Name Decoding
Maybe you have wondered about the file names of the IGC log files that are generated by your flight recorder. For example, "15KC3WK1.IGC". It looks like a strange random combination of letters and numbers, but each character does have a meaning. In the example above it means, "1st Flight on May 20th, 2011 using a Cambridge flight recorder serial number 3WK". Simple? Not so much.
Please see this web page for more information.

Here is a

Cambridge Flight Recorders
The Cambridge Aero Instruments line of flight recorders are very popular with soaring pilots. Here is a
with some additional information on the following subjects;
O'Hare Class B Airspace Expansion
In mid-2008 the FAA started the process of expanding the O'Hare Class B airspace. This change was implemented on October 21, 2010. This has directly impact several soaring sites in the Chicago area, notably Sky Soaring near Hampshire, IL. More information can be found by clicking on this link|
Glider Maintenance Tool Box
A list of many things that you will need in a maintenance kit for your glider and during your road trips.
My Aviation Image Gallery
A repository of aviation images. Gliders, humor, powered airplanes, etc, etc.
Various pictures of my DG-101G ELAN (and a great home built trailer). What a fun, safe, ship to fly!
|Here are a few interesting soaring movies for your viewing pleasure. See this web page for more details.
Standalone Flight Recorders
|I have built two different types of standalone flight recorders for club use in mutiple ships. Each has it's pros and cons. See this web page for more details.|
NOTE: - While the club still owns and uses the EW Microrecorder, the Nano and other very small recorders definately look like interesting future choices.
Car Laptop Desk
|Great for retrieves! I built a simple laptop desk for the passenger's seat. It incorporates lighting, a 12Vdc power strip and a 110Vac inverter. I use it with a Delorme GPS system for retrieves. See this web page for more details and pictures.
Wedekind Safety Sleeve Installation
Everything that you wanted to know about L'Hotellier fittings and the several ways to comply with the FAA AD about them. Also, a step-by-step guide to the stallation of Wederkind Sleeves on a glider with L'Hotellier fittings. See this web page for more details and pictures.
Blanik L-13/L-23/L-33 Strut Information and Repair
(Click Image to Enlarge)
The repair/rebuild of the L-13/L-23/L-33 strut landing gear strut is an important skill if your strut has collapsed and is no longer holding gas (typically nitrogen). A repair/rebuild kit is required for the repair/rebuild. Old parts should not be reused and are not commonly available. To my knowledge kits are only available from Blanik (approximate cost US$500). Note that a replacement new strut is much more expensive. Also note that L-13's have been effectively grounded (at least in the US) and used struts from an L-13 can be reused in L-23's and L-33's.
