Introduction: I have created several presentations on various glider related topics EXCEPT for anything to do with flying (well). I haven't quite figured that out as yet.

Avionics Wiring for Soaring Pilots

I have seen many glider avionics installations which have made my hair stand on end (or fall out altogether)! This presentation is intended to provide basic instruction in some best practices on the wiring of avionics. Topics include wires types and gauges, crimp lugs, power, batteries, installation, mounting, etc.

Oxygen Systems for Glider Pilots

Once you have experienced the joys of soaring to high altitudes, you will want to do it again and again. However, you must learn how to use an oxygen system in your glider and, most importantly, lean how to conserve the limited amount of oxygen that you can take aloft. This simple presentation will help you learn how to create and use an oxygen system.

Trailer Wiring & LED Conversion

Trailer wiring can be daunting. Converting a European trailer like a Cobra to a US connector can be a chore. Then dealing with burn out or corroded bulbs can be frustrating. This presentation may just help you!

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.

Battery Testing

Each year I like to test my ship's batteries and replace those that do not have enough individual capacity to last 6 hours at a 1A load. But how can the average pilot perform a reasonable "real world" test with easily obtainable equipment?

See this information 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.

Survival Kits

Over the years I have created a survival kit which I carry in my glider at all times to be prepared for landouts. There is another version for when I fly out west. See this web page for more details.

Cambridge 302 Flight Recorders

The Cambridge Aero Instruments line of flight recorders are very popular with soaring pilots. Their last production produced was the model 302 (and 302A) which is highly regarded by glider pilots. Here is a web page with some additional information on the following subjects; logging error fixes,tones decoded, software and manuals, simulators.

L'Hotellier and Wedekind Sleeves

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 installation of Wederkind Sleeves on a glider with L'Hotellier fittings. See this web page for full details and pictures.

Carbon Fiber Instrument Panel Overlay

This presentation talks about applying the following types of carbon fiber to the face of an instrument panel plus the pros and cons of each with examples of the finished products;

  • Rigid sheets of real carbon fiber panels
  • Non-rigid sheets of 3M's Di-Noc "carbon fiber"

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, "85KC3WK1.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, 2018 using a Cambridge flight recorder serial number 3WK". Simple? Not so much. Please see this web page for more information.

Blanik L-13/L-23/L-33 Strut Information and Repair

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.

Several items are included here for downloading;

  • Scans from the L-23 service manual on the repair/rebuild/refill of the strut.
  • Pictures of an actual repair/rebuild of a Blanik L-33 strut. This should be the same for an L-13 or L-33.
  • Scans from the instructions included with the 2015 purchase of the repair/rebuild kit for the Blanik L-13/L-23/L-33 strut. This also includes how to build custom tools to facilitate repair/rebuild.
  • Pictures and information on refilling the Blanik L-13/L-23/L-33 strut with nitrogen.

Old Presentations that Need Updating



SPOT, Emergency Locator Transmitters (ELT) and Personal Locator Beacons (PLB)

NEEDS SOME SERIOUS UPDATING!

This presentation talks about the basics of what SPOT, ELTs and PLBs do and how they might benefit you. It covers the applicable ELT FARs and TSOs. It also covers the 6 September 2007 announced termination of processing of distress signals emitted by 121.5 MHz by the International COSPAS-SARSAT Organization 1 February 2009 and how that might impact you. A comparison is shown between the features and pricing of the SPOT versus the ACR ResQFix PLB.

Soaring Flight Computers

NEEDS SOME SERIOUS UPDATING!

This presentation details GPS systems for use for soaring pilots. I talk about how flight recorders are used, how they are wired together, how to upload and download flight logs and other details. I deal with what flight computers bring to the party, how they can help soaring, how they enhance moving map PDA displays, file structure, etc.

Download this 2007 SSA Convention presentation for complete details.


Basics of Dr Jacks BlipMaps and BlipSpots(PLB)

NEEDS SOME UPDATING!

Here is a short presentation on the use of blipmaps and blipspots which was created for a ChicagoLand Glider Council meeting.

Download this 2007 presentation for complete details. Also available is Dr. Jack's presentation from the 2003 SSA convention (by kind permission).
